Troubleshooting Steps
1. If there is an issue with any of the keys on the flip
assembly, check the contact pads on the flip
assembly for damage, dirt, or oxidization. If any of
the contact pads show signs of dirt or oxidization,
clean the contacts. If any of the contact pads are
damaged, replace the flip assembly.
2. Also check the flip assembly's board connection for
damage, dirt, or oxidization. If the connection
shows signs of dirt or oxidization, clean the
connector. If connector is damaged, send the unit to
a location approved to perform electrical repairs.
3. If the information in the display does not reduce to
the visible display area when the flip assembly is
closed, check the flip switch for dirt, oxidation, or
damage. If the flip switch is dirty or oxidized, clean
it. If the flip switch is damaged, send the unit to a
location approved to perform electrical repairs.
