1. Assembling the transmitter HiFi CD-Recorder DVD-Recorder Walkman etc. SCART Power supply unit The volume adjustment of the TV, HIFI, CD should be set to a comfortable listening level for other members of the household.
2. How it works When you first charge the battery packs for the headset receiver, charge them for at least 6 hours. Only use original battery packs. The package includes two battery packs and one dummy. You will recognize the dummy as it has no metal contact surfaces. Standby indicator: The blue LED indicates that the device has established a connection with the audio source and is on Send.
3. Radio range The transmitter is designed to have a radio signal range of 80 metres under optimum conditions. The following conditions may result in a reduced range: n Signal transmission through building structures or vegetation n Interference from TVs, computer monitors and mobile phones. Under certain circumstances, this may prevent the receiver from functioning at all. n Positioning of the transmitter at an unfavourable distance from surfaces which reflect radio waves, for example floors and walls.
4. Channel selector A, B, C With the channel selector you can change the frequency of the transmitter. If channel A is distorted you can change to another channel. NOTE: If the transmitter is switched to another channel, the receiver also has to be set to another channel. (See specifications.) The channel selector is located on the rear side of the transmitter or receiver. Transmitter and receiver must both be set to the same channel.
5. Volume adjustment of the receiver There is no ON/OFF switch! The receiver automatically switches on when worn. The stethoscope headset will switch off automatically when you remove it.
6. Battery pack replace If the sound quality of the receiver becomes noisy and distorted you should replace the battery pack with a charged one or charge the receiver, including battery, in its cradle. WARNING: Do not force the battery pack into the charger or receiver! How to get the most out of your rechargeable batteries Please make sure that both batteries are used on a regular basis. Constantly recharging the batteries will shorten their service life.
7. Maintenance of the headset receiver The ear pieces have to be cleaned or exchanged if dirty. To replace, please use the silicone earpieces for DIR headsets.
8. Replacing the silicone covers with the transparent cover of the volume control The transparent cover has the following protective functions: n It prevents any unintentional changes in the volume level. n It protects dust and liquids from coming into contact with the volume control.
