RS232 Test
To run the test:
1. Select the RS232 Test from the Peripherals menu.
2. Attach the loop-back connector to the round connector
on the bottom of the hand-held computer, then press
[ENT]. The display changes to the second RS232 Test
menu (shown above).
The condition of each line-pair displays as passing or failing
the test. If any test fails, the hand-held computer should be
returned for service.

The Display Test activates each element in the LCD dis-
play. If a line appears broken, or there are gaps in the dis-
play, the LCD panel needs to be replaced.
