USER MANUAL Eco Control Audio 500 NUK

1. Description of device

This baby monitor Eco Control Audio 500 allows you to listen in to your baby or small child in the nursery. It can also be used for sound-only monitoring of the elderly. This device is intended only for dry environments. It is not suitable for use in wetrooms or outdoors in wet weather. This device is intended for use in private households. It is not intended for commercial use. This device is intended as a supplementary aid. It is in no way a substitute for the physical presence and attention of parents, babysitters or carers.

1.2 Description of function

The baby unit 1 is set up in the room that is to be monitored. It registers the sounds in the room and sends it wirelessly to the parent unit 8. The parent unit 8 has a built-in rechargeable battery so that you can always set it up where you can see it. The battery is recharged using the supplied mains adapter. The limiting distance between baby and parent unit is about 40 m indoors and up to 250 m outdoors (in open country). The babyphone’s reception will vary depending on its surroundings. Thick walls or metal can reduce the range. The babyphone has an Eco-Mode, in which the transmitter (baby unit) automatically switches to standby as soon as your baby is sleeping peacefully. Depending on the sensitivity setting, it will not switch back on until your baby begins making a noise or starts to cry. If you want to be sure of hearing every single sound from the nursery you can use the VOX 17 button to set the transmission sensitivity to its maximum (=level 5). On this setting the baby unit is continually switched on (see "6.3 Using the VOX function to adjust the transmission sensitivity" on page 28). If you do not want to hear any sounds at all you can use the Vol - 11 button to set the volume to mute. In this case only the LED display 16 will show you if your baby is making noise. Activating Eco-Mode minimises the high- frequency radiation in the children’s room. In this mode the baby unit merely sends a brief signal to the parent unit every 30 seconds to test the connection. If the parent unit is out of range, the parents will be alerted by a beep. You will find more information about Eco- Mode in "4.5Eco-Mode" on page 26 and in "6.3Using the VOX function to adjust the transmission sensitivity" on page 28.

The baby monitor operates at a frequency of

2.4 GHz. This device may be used in all EU

countries. In Russia and Ukraine you should comply with the specific national restrictions.

2. Put the battery in its compartment as

indicated on the unit. Make sure you insert it with the correct polarity (+ and -).

3. Slide the battery cover 9 back onto the

4. Insert the small plug of the mains adapter

into the mains adapter socket 19 of the parent unit.

5. Insert the plug into a power socket that

matches the rating given in the technical data (see "9. Technical data" on page 31).

6. Initially, charge the parent unit

continuously for 10 hours to activate the full battery capacity. Subsequently the battery will take only about 5 hours to charge. It can also be charged while the unit is in operation. The POWER 15 LED indicates that charging is in progress. If it: – flashes green: the battery is currently being charged; – lights up green: the battery is fully charged; – lights up red and beeps at one minute intervals: low battery warning. Within about 15 – 20 minutes the parent unit will switch off automatically.

4.2 Connecting the baby unit

Note: Don’t install the baby unit 1 until the battery of the parent unit 8 is fully charged.

1. Put the baby unit 1 somewhere in the

nursery where your baby will not be able to reach it. An optimal distance between baby and the baby unit is from 1 to 2 m.

2. Insert the mains adapter plug into the

socket 3 of the baby unit 1.

3. Insert the plug into a power socket that

matches the rating given in the technical data (see "9. Technical data" on page 31).

4.3 Connecting baby unit and

baby unit 1 on. Keep the button pressed for a moment until the Power LED 6 lights up.

2. Use the On/Off button 14 to switch the

parent unit 8 on. Keep the button pressed for a moment until the LED 15 lights up a steady green. The connection will be set up automatically. While this is being done the connection indicator 13 will light up red. As soon as the connection has been established, the connection indicator on the parent unit 13 and the VOX LED on the baby unit 7 will light up green. If the connection indicator 13 begins to flash green, this means that there is a connection between the parent unit and the baby unit, but your baby is currently asleep and therefore the device has automatically activated Eco-Mode to reduce the high-frequency radiation in the children’s room and save energy. In the event that the connection between the parent unit and the baby unit breaks down, the devices will automatically attempt to establish a new one. If a new connection is not established within 30 seconds, the parent unit 8 will emit a regular beep and the connection indicator 13 will light up red. You may need to move the parent unit to a different location before a new connection can be established.

3. First go and check on baby to make sure

4. Then try to set up a new connection by

moving about. The connection will be automatically re- established as soon as you are within range.26 As soon as the connection has been set up the connection indicator 13 will again light up green.

  • The power supply for the baby unit 1 works only via the mains adapter.
  • The parent unit 8 can be operated with no mains connection using the battery. The state of the battery is indicated by the POWER 15 LED. If it: – lights up green: the device is switched on and the battery is fully charged; – flashes green: the battery is currently being charged; – lights up red and beeps at one minute intervals: low battery warning. Within about 15 – 20 minutes the parent unit will switch off automatically. During these 15 minutes you can still activate and deactivate any functions you wish. Please be aware that using e.g. the Talk-Back function and/or maximising the volume control will increase the unit’s power consumption and therefore reduce the remaining time you have available. You should connect the mains adapter to your mains supply as soon as the POWER 15 LED begins to flash red.
  • The parent unit can be connected to the mains via the mains adapter and receive power from there, while at the same time recharging the battery. If the parent unit is switched on, recharging the battery will take somewhat longer. While the battery is charging, the LED 15 flashes green. Notes: – With a fully charged battery you can operate the parent unit for up to 18 hours. The exact time will depend on how the unit is used (whether the parent unit frequently switches on, whether the two-way speaking function is much used, how high the volume is set, etc.). – Charging an empty battery takes about 5 hours.

Description of function This babyphone has an Eco-Mode setting, which not only saves electric power but also minimises the high-frequency radiation in the nursery. At VOX levels 1, 2, 3 and 4, (see "6.3 Using the VOX function to adjust the transmission sensitivity" on page 28) Eco-Mode is activated automatically about 10 seconds after your baby goes to sleep and no longer makes any noise. You can see when this happens because the connection indicator 13 will begin to flash green. In Eco-Mode, not only the baby unit is automatically set to standby, but also the parent unit. While Eco-Mode is activated, any functions that might wake the baby are automatically deactivated. For example, you cannot use the Talk-Back function, but even in Eco- Mode you are always connected to your baby and always know if you are still within range. This babyphone has a range checker that also works in Eco-Mode. If you are out of range, you will automatically receive a warning even if Eco-Mode is activated, because even in standby mode, the baby unit sends a signal to the parent unit every 30 seconds to check the connection. If the connection indicator 13 lights up green, there is a functioning connection between the baby unit and the parent unit. If the connection indicator 13 flashes green, Eco-Mode has been activated. If the connection indicator 13 changes to red, this means that you are out of range and/or the two units are no longer communicating. Note: Check the range of your baby monitor before using Eco-Mode. Make sure that the two units are always within range, so that you can hear your baby. The device automatically switches to transmission mode as soon as your baby27 makes a noise that exceeds your selected sound threshold (VOX levels 1 - 4). Eco- Mode is deactivated immediately and the connection indicator 13 stops flashing. At VOX level 5 the device transmits continuously and Eco-Mode is deactivated. If you want to check that everything is OK while Eco-Mode is activated (although this already indicates that your baby is sleeping peacefully), you can deactivate Eco-Mode by switching to permanent transmission mode:

until all 5 LEDs 16 are lit.

and off The baby unit 1 will switch on automatically as soon as you have connected the mains adapter and plugged it into the power supply. You can subsequently switch the baby unit on or off at any time:

  • The Power LED 6 lights up green while the baby unit is switched on.
  • The VOX LED 7 on the baby unit lights up green when there is an established connection between it and the parent unit.
  • The VOX LED 7 will not be lit while the baby unit 1 is switched to Eco-Mode or if it was not possible to set up a connection to the parent unit.

on and off To switch the parent unit 8 on or off, press and hold the On/Off button 14: – when you hear a beep and the Power LED 15 lights up, the parent unit is switched on; – when you hear a beep and the Power LED 15 goes out, the parent unit is switched off.

  • The connection indicator 13 on the parent unit 8 shows the state of the connection to the baby unit 1. It: – lights up green when it has a connection; – flashes green when the baby unit is in Eco-Mode and indicates that your baby is sleeping peacefully; – lights up red if the connection has broken down or the baby unit is switched off. Notes: – If the baby unit 1 is in Eco-Mode and the parent unit moves out of range, the connection indicator 13 will light up red. You will also hear a beep every 30 seconds. – As soon as the parent unit 8 comes back into range, or the reason for the breakdown in communications is eliminated, the connection indicator 13 lights up green again indicating that the units are able to communicate. – When the units are first switched on, the connection indicator 13 will initially be red. The parent unit and baby unit will set up a connection. As soon as the connection is set up the display will turn green.28
  • The power supply indicator POWER 15: – lights up green: the device is switched on and the battery is fully charged; – flashes green: the battery currently being charged; – lights up red and beeps at one minute intervals: low battery warning. Within about 15 – 20 minutes the parent unit will switch off automatically. Please be aware that this interval may be reduced, depending on how you use the device (for example, VOX level 5 uses more power than level 1).
  • The display 16 with the 5 LEDs has three functions. The LEDs are only visible when in use. – indicates the noise level in the nursery. The more LEDs are lit, the louder the noises; – indicates the different levels when you are adjusting the volume. The more LEDs are lit, the louder the sound from the loudspeaker; – indicates the different levels when you are adjusting the VOX sensitivity. The more LEDs are flashing, the sooner the device will react to sounds. If 5 LEDs are lit the device will switch to continuous transmission.

6.3 Using the VOX function to

adjust the transmission sensitivity Babies make a lot of different noises. These can range from loud breathing through babbling to calling or loud crying. The VOX function can be set up in such a way that only loud sounds such as crying or calling are transmitted while quieter sounds are not registered. The VOX function sets up the transmission sensitivity of the microphone. The higher the VOX level the more sensitive the device is to noises.

1. You activate the VOX function by briefly

pressing the VOX button 17. The LEDs 16 indicate the sensitivity of the current setting by flashing.

2. You can increase or decrease the

transmission sensitivity by pressing one of the buttons VOL + 10 or VOL - 11. The number of flashing LEDs 16 corresponds to the selected level: – VOX level 1 = extremely low sensitivity, reacts only if baby screams really loudly; – VOX level 2 = low sensitivity, reacts if baby screams loudly; – VOX level 3 = normal sensitivity, reacts if baby cries normally; – VOX level 4 = high sensitivity, reacts even to slight sounds; – VOX level 5 = Eco-Mode is switched off. The unit is set to transmit continu- ously. You can set up the volume at which the parent unit should output the transmitted sounds using the two buttons VOL + 10 and VOL - 11 (see "6.4 Adjusting the volume control" on page 29). Note: After activating the VOX function, you have about two seconds to alter the transmission sensitivity. The device will then automatically switch back to transmitting sounds. You can see this has happened because the LEDs 16 will no longer be flashing, and the VOL + 10 and VOL - 11 buttons now only modify the volume. Caution! In continuous transmission mode at VOX level 5, all sounds are transmitted continuously. When the baby is sleeping peacefully, the volume is automatically reduced to its lowest level after a few seconds to minimise background noise. As soon as the child begins to make a noise, the volume automatically returns to its previous setting.29

6.4 Adjusting the volume

1. You can use the VOL + 10 and VOL - 11

buttons to set the volume at which you hear the sounds emitted by the parent unit. Each time you press one of the buttons you will hear a beep at the volume that is currently set up and it will show you with the accordance of lit LEDs 16. The louder your chosen setting, the louder any beeps will be and the more LEDs will light up. Note: When the VOX function is set to low sensitivity (see "6.3 Using the VOX function to adjust the transmission sensitivity" on page 28), then quiet sounds will not be transmitted regardless of the volume setting. This means that turning up the volume will not enable you to hear anything more. If you want to hear more of the sounds from the nursery you will need to increase the transmission sensitivity by selecting a higher VOX level.

The parent unit can be “MUTED”. Sounds from the nursery will then no longer be transmitted.

1. Press the VOL - 11 button repeatedly

until you can no longer hear beeping. No sounds will now be transmitted.

2. The LEDs 16 will continue to indicate the

noise level in the nursery. The more LEDs are lit the louder are the noises in the nursery.

3. You can cancel the mute setting by

pressing the VOL + 10 key.

4. If the parent unit is muted and you

You can use the “Talk-Back” function to speak to your baby.

1. Hold down the TALK 18 button on the

parent unit. When you hear a beep, this means that voice connection is established.

2. At the same time, speak into the

microphone 20 on the parent unit. Your baby can now hear your voice from the loudspeaker 2 on the baby unit.

3. Release the TALK 18 button in order to

hear the baby’s reaction. Notes: – If the baby unit 1 is in Eco-Mode, this function is deactivated so that you do not inadvertently wake your baby. In this case, two consecutive beeps will remind you that the Talk-Back function is currently not available. – If the volume of the parent unit is set to “MUTE” (see "6.4 Adjusting the volume control" on page 29), it will automatically be increased to level 1 as soon as you press the TALK 18 button.

7. Cleaning and care

Warning! To avoid the risk of electric shocks, injuries and damage: – Always disconnect the mains adapter from the power socket before cleaning the device. – Never immerse the individual parts in water. Caution! Under no circumstances use abrasive, corrosive or scratching cleaning agents, as these could damage the device.

The wireless transmissions of this baby monitor use modern FHSS technology. Frequency Hopping Spread Spectrum (FHSS) is a digital frequency spreading method for wireless data transmissions. Unlike earlier methods, the whole of the transmission power is not concentrated on a single frequency. Instead, the carrier frequency is changed at random. The individual data packets transmitted via the different carrier frequencies are then reassembled in the receiver. This method has several advantages over conventional radio transmission:

  • It is also much more difficult to intercept the radio signal, because the listener does not know how the signal is distributed among the different frequencies and how to correctly reassemble it. For this reason the same method is used by Bluetooth and by the military.
  • Radio transmissions that use this method are also much less susceptible to interference. This is because a given carrier frequency is always used only very briefly before switching to another. If there is interference on one frequency it will affect only small data packets, and appropriate correction algorithms can compensate for such errors. Wireless connection 2.4 GHz FHSS Transmission frequency 2408 MHz - 2474 MHz, max EIRP 100mW Number of channels 12 / automatic channel selection Line of sight range about 250 m Range within enclosed rooms about 40 m. Successful transmission depends on the environment. Walls or trees can seriously interfere with reception.

In addition to the seller's warranty obligations arising from the contract to purchase, we as the manufacturers provide a warranty of 24 months from purchase of the appliance as long as the appliance is used properly and the operating instructions are followed. Evidence of the date of purchase and the type of appliance should be provided by means of a receipt. The purchaser's statutory rights are unaffected by this manufacturer warranty. During the warranty period, we undertake to remedy any defects attributable to poor materials or workmanship. Wear parts are excluded from the warranty. Minor deviations from specified quality which do not affect the value or usability of the appliance are not covered by the warranty. We are likewise unable to accept the warranty if the defects on the appliance are due to transport damage for which we are not responsible, if they are attributable to misuse or lack of care or if the appliance has been interfered with by persons not authorized by us to do so. The warranty service will involve repair, replacement of parts or replacement of the appliance at our discretion. The warranty period will be neither extended nor restarted by the performance of warranty services. The warranty for any spare parts fitted will expire with the warranty for the appliance as a whole. Extended or different claims, especially those relating to the making good of damage sustained outside the appliance, are excluded unless liability is compulsory in law. We will not accept the costs or risks of transport. An appliance sent in without evidence of the purchase date will be treated as a repair. The appliance will only be repaired following discussion with the customer.
