Connecting the transmitter

1 Connect the power adapter to the DC IN input socket located on the transmitter rear panel.
2 Connect the power adapter provided to an electrical outlet.
3 Connect the transmitter to your audio source.

RCA adapter cable, audio cable, 6.3 mm to 3.5 mm adapter plug and an external microphone are provided for various type of connection to your audio source (e.g. TV set, Hi-Fi system, MP3 or iPod).

Please note that only one input (either analogue audio input or optical input/TOSLINK) must be connected.

The green power indicator LED will blink as soon as you have connected the power adapter to the electrical outlet and when the audio signal is detected from the audio source, the green LED indicator will glow constantly.

Using the optical TOSLINK digital audio cable

If your audio source has an optical audio output (TOSLINK/S-PDIF), connect the two devices with the included optical TOSLINK digital audio cable. This connection offers a higher transmission quality and a lower susceptibility to electrical and magnetic interference.

Please make sure the optical TOSLINK digital audio cable does not get bent or folded! Avoid tight bending radii.

• A fully charged battery provides up to 5 hours of listening enjoyment.
• To conserve battery power, the receiver automatically shuts off if no signal is detected for a period of approx. 5 minutes or when the level is too low. However, if the signal returns to an acceptable level, the transmitter will automatically switch ON again.

Changing the rubber ear buds

Two pairs of ear buds are delivered with the device (L=large/S=small).

The ear buds "L" (large) are already mounted on the headset.

1 For changing the ear buds pick the mounted ear buds at the end and tear them off simply.

2 Position the spare ear buds onto the "open ends" and let them snap into place.

External microphone

If your TV set or HiFi system does not have any audio jack you should use the external microphone.

1 Connect the analogue audio cable to the microphone.
2 Fasten the microphone holder using the adhesive strip adjacent to the speaker grill on the TV and then clip the microphone into the holder so that it locates just above the speaker.
3 Please set a very low volume on the TV / on the HiFi system. The position of the microphone has a decisive influence on the volume - please determine the best position by experimentation.

Note: The output will be in mono when using the microphone.

Please make sure that the microphone is not too close to the sender, otherwise this will result in interference being picked up by the microphone which will be heard as digital noise in the headset.

Setting up an additional receiver (TV 2400-1 / TV 2410NL-1)

Your TV 2400-1 / TV 2410NL-1 is an additional receiver for your TV 2500 / TV 2510NL. After having inserted and charged the battery you will have to register it to the transmitter. There is no limit number of receivers to be registered to the TV 2500 / TV 2510NL transmitter for use together.

Inserting and charging the rechargeable battery

1 Insert a battery into the headset receiver.
2 Charge the battery before first use. Switch off the receiver (position OFF). Place the receiver into the charging cradle of the transmitter. The charging process starts automatically. The battery LED indicator will be red and will turn to green when the battery is fully charged. This takes about 2 hours and 30 minutes.

Alternatively you can use the fully charged spare battery from the transmitter.

Registering the receiver

1 Turn off the transmitter if it is on (disconnect from the mains).
2 Disconnect the audio source input.
3 Turn on the NEW headset, the LED indicator will be flashing on and off slowly.
4 Press the MIC button and hold for 3s, the green LED indicator will flash on and off quickly.
5 Turn on the transmitter immediately (must be done within 9s, or need to redo step 4).
6 If the registration is successful, you will hear a short confirmation tone in the headset and the green light on the headset will automatically stop flashing and will light constantly. This indicates that registration was successful.
7 Reconnect the audio source input.

Operation

Operation

Hearing damage due to high volumes!

This receiver allows you to set higher volumes than conventional headphones. This can cause hearing damage in persons with healthy hearing and especially in children.

- Before putting the receiver on, set the volume on the receiver to a low value.

- Do not continuously expose yourself to high volumes.

1 Switch on the audio source. The green indicator LED on the transmitter will glow constantly.
2 Switch the On/Off switch on the headset receiver to ON position,
3 Flex the head set arms outwards until the ear buds can be inserted in the ear. Please note the ear buds can be angled through a movement up, down or sideways, so as to enter the ear a little deeper. This will improve the sound quality and volume. Gently press the ear buds further into the ear to find a comfortable position for the ear buds and an ideal position for the sound.

4 Adjust the tone clarity setting if necessary.

Note: When the battery level is low you will hear 3 beeps every minute in the headset receiver. The headset receiver will be switched off automatically after 5 minutes.
