Battery Troubleshooting
There is a slight risk of explosion if you replace the batteries with an incorrect type. Call
the PRC Service Department before replacing the batteries: (800) 262-1990. Outside the United
States, call your local distributor.
Use only the battery charger that came with the device. Other chargers may damage the
batteries in the device.
If the batteries die:
A low battery warning will sound when the batteries are getting low; a more urgent sound will
be heard when the batteries are critically low.
If NuVoice is running, yellow NuVoice warning boxes will appear instructing you to plug in the
battery charger.
If NuVoice is not running, the Windows “low battery” and “shutting down” warnings will
appear.
Plug in the battery charger to continue using the device. If the charger is not plugged in,
NuVoice and/or Windows will shut down and the device will turn off. To restart your device,
plug in the battery charger and press the power button. If the batteries are completely dead,
allow them to completely charge before turning the device on again.

High-Efficiency Fluorescent Lights and the Use of Infrared
There is often a compatibility problem between many infrared controls and high-efficiency
fluorescent lights.
If the device is being used in a room that has high-efficiency fluorescent lighting, the infrared,
including headpointing, computer access, remote control commands, etc., may not work. Turn
the lights off and the IR will work correctly.
