5. MAINTENANCE
Manual Selecting of Transmitter Battery Type
The type of batteries being used-Alkaline or rechargeable NiMH-are recognized
automatically during power up of the device or may be defined manually by the user.
Set battery type as alkaline:
1. Make sure that the Transmitter is turned off.
2. Press and hold the VOLUME UP (+) button.
3. While volume up button is pressed, press the power button. The chosen battery type will
be alkaline.
Set battery type as rechargeable NiMH:
1. Make sure that the Transmitter is turned off.
2. Press and hold the VOLUME DOWN (-) button.
3. While volume down button is pressed, press the power button. The chosen battery type
will be rechargeable NiMH.
If the battery type is not defined manually, it will be recognized automatically. Automatic
battery type recognition draws more current and can be unreliable if inadequate or
old batteries are used. The automatic battery recognition can also be unreliable if the
rechargeable batteries have not been charged in over one month.
