Troubleshooting Steps
1. If the display is not illuminated and the customer's
battery is present with the phone, check that the
contact pads on the battery are not damaged, dirty, or
oxidized. Clean the contact pads or replace the
battery as necessary.
2. Check whether the phone's battery connector is
damaged, dirty, or oxidized. If the battery connector
is dirty or oxidized, clean it. If the battery connector
is damaged, send the unit to a location approved to
perform electrical repairs.
3. Check the tactile response of the power on/off key.
The key should feel like it is clicking when it is
depressed (most likely a click will not be heard). If
the power on/off key does not feel like it is correctly
responding when depressed, disassemble the phone,
pull the power key out of its hole in the frame, and
check for debris around the key (the key can be
pulled back out of its hole, but it cannot be removed
from the back cover). If necessary, clean the key
hole and around the key. If the key is damaged,
replace the back cover.
