USER MANUAL BM 850 BABYFON

1 Introducing your new BABYFON ® BM 850 With your new BABYFON ® BM 850 you have chosen a quality product from VIVANCO. You can rely on the support provided by your new Babyfon and always hear your baby, no matter where you are in your home. N.B.: As the BABYFON ® BM 850 is a radio frequency device, certain settings on both devices must be absolutely identical to ensure that the transmitter and receiver can communicate with each other. Please refer in particular to chapter "5.2 Setting the channel and the personal security code". The BABYFON ® BM 850 provides the following functions: ESR - Electro-Smog Reduction Thanks to a new technology the electro-smog occurring near your baby is reduced considerably. This function is activated automatically as soon as the Babyfon is switched on; no further adjustments are required. Variable transmission output If the transmitter and receiver are close together (child's room and living room) you can reduce the transmission output. This considerably reduces any possible electro-smog (during transmission) even further. You protect your child from unnecessary electro-smog without impairing the functionality of the device at the same time. 863-865 MHz / 4 channels The BABYFON ® BM 850 operates in the frequency range from 863 to 865 MHz. This eliminates interference from conventional baby-monitoring devices and with four different channels you can avoid any other unwanted influences. Personal security coding To ensure optimal protection from external FM applications your Babyfon provides personal and individual coding. A personal code is created by entering a name or sequence of letters. This is transmitted simultaneously with the voice transmission. Only if this personal code corresponds to that of the receiver is the transmission accepted by the receiver and you hear only your own child. Variable response sensitivity To ensure optimal adaptation to your living conditions and ambient noise you can determine when the BABYFON ® BM 850 switches itself on and transmits. Acoustic range control When the acoustic range is activated a warning tone tells you that you are leaving the reception range. This warning tone stops automatically when you are back within the reception range. Keylock function The keylock prevents accidental adjustments to settings and thereby further increases the functional security of the device. Battery pack charge function The BABYFON ® BM 850 is equipped with an integrated battery pack charge function for the gentle charging of environment-friendly nickel-metal hydride battery packs. Battery pack status display A symbol in the receiver display and a warning tone indicate that the battery packs need charging. On the transmitter this is indicated only by a flashing symbol in order not to disturb your child. Belt clip / wall mounting The BABYFON ® BM 850 is fitted with a practical belt clip. Using a screw or hook you can also use the belt clip as a practical wall mounting.19 Use of the BABYFON ® BM 850 cannot replace, but only support the personal supervision of a child or person in need of care. We point out that we do not accept any responsibility whatsoever not covered by legal guarantee regulations. This applies in particular to this Babyfon being used for medical purposes for which it is not intended. The device is designed for private use.

3.3 Electro-smog in children's rooms

Due to the low radiation level there is no risk to your child's health as a result of electro-smog, according to current knowledge. We nevertheless recommend that you keep a safety distance of at least 1 metre between your baby and the BABYFON ® BM 850. The functionality of the BABYFON ® BM 850 is not impaired by the safety distance! Never place the transmitter inside the child's cot or playpen. The original Babyfon is equipped with a voice control feature that allows the device to transmit only when your child actually makes a sound. Therefore the BABYFON ® BM 850 transmits only when required and not permanently. This sensible function prevents superfluous electro-smog. When using plug-in chargers (AC adapters) you can minimise low-frequency magnetic fields by keeping a distance of 1 to 2 metres between the wall socket and the child's cot. Your Babyfon is equipped with intelligent charging technology. The plug-in charger becomes active only when the battery packs have been discharged below a certain lower limit. It then charges the battery packs up to a certain upper limit and becomes inactive again; the battery packs are now used as the power source. This means that you have optimal protection from additional electro-smog, even when the battery packs are being charged. This ensures that there will be no risk of electro-smog from the BABYFON ® BM 850 for your child.

3.4 Protecting the devices

When the devices are running they need sufficient air supply. If you use batteries, remove them if the devices are not used for a long period as they could otherwise leak. Switch off the devices after use. Protect electronic devices from moisture. The devices must under no circumstances come into contact with liquids. Therefore make sure that they are not submerged under water and that no liquid gets inside the casing. Protect electronic devices from temperatures above 40 °C. Therefore do not leave your BABYFON ® BM 850 in strong sunlight and never place it on hotplates or close to other heat sources. Always check before use that your BABYFON ® BM 850 functions correctly (see "4.3 Function test"). Defective devices must not be used. Never carry out repairs yourself; contact your dealer if the need arises. Never use caustic detergents to clean the devices as these could damage the plastic surfaces. Clean the devices with a dry or slightly moist cloth.

3.5 Using the plug-in charger

Connect the device only to a correctly installed mains socket with voltage which corresponds to that given on the nameplate of the plug-in charger. Make sure that connecting cable is not positioned so that people could trip over it. Make sure that the connecting cable is not pinched, crushed or stretched. When using an adapter or an extension cable, make sure that these comply with valid safety regulations. The maximum current given must not be exceeded.

6.1 Battery pack status indicator

The battery pack status indicator C5 indicates how full the battery packs are or, if batteries are used, how full these are: Battery packs/batteries full (3 bars) The batteries or battery packs are full or nearly full, allowing operation for several hours. Battery packs/batteries 2/3 full (2 bars) The batteries are partially emptied, but still allow normal operation. Battery packs/batteries 1/3 full (1 bar) The batteries are almost empty. Now is the time to replace the batteries or recharge the battery packs. Battery packs/batteries empty When the batteries or battery packs are empty the last status bar disappears and the battery pack status indicator C5 begins to flash. The device also emits a warning tone. Proper operation is no longer possible and the device switches itself off automatically after a few seconds.

6.2 Charging the battery packs

The BABYFON ® BM 850 comes with automatic charging control. To use this feature, the devices must be connected to the AC adapter D. If the battery pack condition falls to an insufficient level the BABYFON ® BM 850 automatically begins charging the battery packs. When the battery packs have been charged the BABYFON ® BM 850 automatically switches off battery charging. Note: Thanks to this automatic charging control the battery packs are protected against both unnecessary overcharging and total discharge, thereby increasing their service life.

1. Insert the small plug on the cable of the AC adapter D into the connection socket for

the plug-in charger A6 / B6 of the device concerned.

2. Plug the AC adapter D into a mains socket with voltage that corresponds to that

given on the charger's nameplate. The control lamp for the plug-in charger A7 / B7 lights up. If the battery packs are empty, charging now begins and the battery pack status indicator C5 indicates that charging is taking place.

3. When the battery packs are fully charged the battery pack status indicator C5 shows

full (3 bars) and the BABYFON ® BM 850 automatically stops charging. When charging the battery packs, please observe the following: N.B.: New battery packs must be charged for at least 10 hours without interruption before use to ensure that they reach their full capacity. The battery pack charging time varies according to the type of battery pack used. The battery packs supplied need approx. 6-8 hours before they are fully charged. Using the battery packs included with the set operation of up to two days is possible. This may vary depending on the mode of operation.

6.3 Battery operation

N.B.: When using batteries the plug-in charger must not be connected under any circumstances as this could cause the batteries to overheat and thereby damage the device.

7. Exit the setting by pressing the mode button (MODE) A4 / B4.

N.B.: Repeat the setting on the other device so that both devices have the same channel and security code settings.

5.3 Setting the response sensitivity (Only on transmitter A)

With the response sensitivity you set the volume at which the transmitter is activated and begins to transmit sound to the receiver. There are several settings available. Find the best setting by trial and error. Press the selection buttons (DOWN/UP) A3 to adjust the response sensitivity. In the dis play the "Response sensitivity / volume" indicator C6 shows how sensitively the transmitter responds. The transmission / reception indicator C7 lights up on the transmitter when it is activated and begins transmitting.

5.4 Setting the transmission output (Only on transmitter A)

If you are close to the child's room with your receiver (example: living room and child's room) you can reduce the transmission output on the transmitter. This considerably reduces any possible electro-smog (during transmission) even further. You protect your child from unnecessary electro-smog without impairing the functionality of the device at the same time.

1. Press the mode button until the transmission range indicator C1 starts flashing.

2. Press the selection buttons (DOWN/UP) A3 to change to half or full transmission

3. Confirm the selection with the confirmation button (OK) A2.

5.5 Setting the volume (Only on receiver B)

You can set the receiver volume at one of several levels. Find the best level by trial and error. Press the selection buttons (DOWN/UP) B3 to set the volume.

5.6 Setting the range alarm/warning tone (Only on receiver B)

The range alarm activates a warning in the receiver when the transmitter and receiver are too far apart to ensure a proper transmission. If the permitted range is exceeded for more than 30 seconds the alarm symbol C2 and the background illumination flash in the display. If the warning tone is activated, this also sounds.

1. Press the mode button (MODE) B4 until the alarm symbol C4 begins to flash.

2. To switch on the warning tone, press the confirmation button (OK) B2. The alarm

symbol C2 then appears permanently in the display. To switch off the warning tone, press the mode button (MODE) B4 again and the alarm symbol C2 disappears.

When the keylock is activated all the keys are locked. The settings can no longer be changed, e.g. if a child gets hold of the device and plays with it or if you carry the device in your pocket. This prevents operating errors.

1. To switch on the keylock, press the confirmation button (OK) A2 / B2 for at least 2

seconds until "KEYLOCK" appears in the display.8.3 Table of malfunctions 9 Contents and technical data

1x BABYFON ® BM 850 transmitter, 1x BABYFON ® BM 850 receiver, 2x AC adapters, 4x battery packs (AAA), operating instructions, warranty pass.

No. of channels: 4 Frequencies: 863 to 865 MHz Power supply: 4 NiMH battery packs (included) or 4 NiCd battery packs or 4 AAA batteries Battery pack charge: AC adapter 9 Volt/200mA Transmission output: max. 10 mW

This Vivanco FM product conforms with the European R&TTE directive for FM systems in non-harmonised frequency ranges. These systems can be sold and operated in the following countries: Germany, France, the Netherlands, Belgium, Spain, Portugal, Italy, Switzerland, Austria, Finland, Norway, Sweden, Denmark.

Instead of the batteries supplied you can also use 4 AAA type batteries. Advantages: longer operating time than with battery packs; greater range as batteries emit higher voltage than battery packs. Disadvantages: higher operating costs as they are not rechargeable; unkind to the environment as they are not reusable. 7 Range of the devices In view of the physical diffusion characteristics of radio waves, you will have to determine the range of your BABYFON ® BM 850 in your surroundings by trial and error. In optimal conditions, the range is up to 400 metres. However, the actual range depends very much on local conditions, e.g. location of the transmitter, type of building or atmospheric conditions. The range may also be reduced if you enclose the receiver in your hands. The spreading of radio waves can be physically influenced only to a slight degree, with the result that there are places in the house or garden where radio contact does not take place although the transmitter and the receiver are only a few metres apart (in a straight line). Due to the numerous factors influencing FM products it is not possible to give a "range guarantee". However, you should be able to move around freely with your BABYFON ® BM 850 within the house/apartment. You can easily determine the range in your surroundings by placing a radio in front of the BABYFON ® BM 850 transmitter. When you can hear the transmission clearly, move around with the receiver in the area where you have perfect functionality. 8 Troubleshooting
