When using more than one tv-base If you only have one base, this base is automatically selected the first time you charge the controller in the base. If you have more than one base, you can change between these by placing the controller in the base you wish to use for approx. 5 seconds.
Usage Up to 1.0 m We recommend that you hang the controller around your neck when in use, on the lanyard provided.
Place the controller in the plastic holder at the end of the lanyard as illustrated. The breakaway buckle of the lanyard must be positioned at the back of your neck (1).
Transmission With either TV or audio connected • Press the transmission on/off key on the controller once to start transmitting from the connected source. An acoustic signal will sound in your hearing aids, and the transmission LED will turn green. • Press the key again once to stop transmission. The hearing aids will enter the Master program as indicated by a voice message or beep tones. The green LED will change briefly to red and then off.
If you carry your controller around with you and move outside the operating range, transmission will be interrupted and your hearing aids will switch to the Master program. The LED will flash at slow intervals to indicate that transmission has been interrupted. The change will be indicated by a voice message. If your hearing aids are set up with beeptone indication instead, no acoustic indication will sound.
Adjusting the volume Press the volume up key to raise the volume of the transmitted TV or audio sound. Press the volume down key to lower the volume. UP DOWN Mute You can mute the transmitted TV or audio sound on the TV or audio source. Room off If you wish to turn the hearing aid microphones off during transmission, so that you only hear the transmitted sound, press the room on/off key once. To turn the microphones back on, press again.
Recharging the battery The controller uses a rechargeable battery. When fully charged, the battery has a capacity of approx. 10 hours of transmission, decreasing over time. When the battery runs low, transmission is interrupted. To recharge the battery, place the controller in the base for approximately 4 hours. You can also recharge the battery using an appropriate USB power supply supplied by Widex. Contact your hearing care professional if the battery needs replacement.
