Removing the Battery and
the System Card
To remove the battery and System Card:
1. Remove the rubber boot, if attached.
2. Place the 475 Field Communicator face down on a level, secure surface.
3. Loosen the battery retaining screws until the top of each screw is slightly above the
top of the 475 Field Communicator.
4. Slide the battery off the 475 Field Communicator. Do not pull up the battery because
this could damage the connector pins.

System Card socket is spring-loaded.
6. Grasp the System Card with your fingers and slide it straight out of the 475 Field
Communicator.
