5. MAINTENANCE
Manual selecting of battery type on AT-6000-TE Transmitter:
The type of batteries being used—Alkaline or rechargeable NiMH—can be recognized
automatically during power up of device or defined manually by user.
Procedure to set battery type as Alkaline:
1. Make sure that the Transmitter is turned off.
2. Press and hold VOLUME UP (+) button.
3. While volume up button (+) is pressed, press the POWER ON button. The chosen battery
type will be alkaline.
Procedure to set battery type as NiMH:
1. Make sure that the Transmitter is turned off.
2. Press and hold VOLUME DOWN (-) button.
3. While volume down button (-) is pressed, press the POWER ON button. The chosen
battery type will be rechargeable NiMH.
If battery type is not defined manually the battery type 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 haven't been charged for over a month.
