Replacing the Battery
Replacing the Battery
The PC3x uses a
fl
at three volt Lithium coincell battery to power the clock. When the battery
voltage runs low, the unit boots up with a low battery message.
Note
: The battery voltage can be checked at anytime using the Scanner Diagnostics. See
page 4-11 for more information.
Accessing the Battery
1. Place the PC3x upside down on a
fl
at protected surface.
2. Remove the seven screws that secure the access panel and set it safely aside.
Removing the Battery
The battery (CR2032) in the PC3x keyboard is mounted into a holder on the Engine Board and is
accessible when the access panel is removed.
1. Insert a
fl
at plastic tool (plastic knife, pen cap, etc.) into one of the openings between the
battery and the holder to lift the battery.
