Self Test
The Self Test should be the initial step in troubleshooting problems
with Optiset E series telephones. The purpose of the Self Test is to
perform an internal check of the telephone. A successful Self Test
causes all status lights to flash once, and the display, if present, to light
for one second.
Begin the Self Test
Unplug and replug the line cord from the telephone base or the wall
outlet and observe the status lights and display. (The process of
unplugging and replugging the line cord is also referred to as “resetting
the telephone.”)
Note:
Make sure the handset is in its cradle before running the Self
Test.
Evaluate the Self Test Results
See if the Self Test results match any of the problems listed below. If
so, follow the recommendations. If not, see if your problem is listed in
“Other Problems” on page B–2.
All the status lights flash, but the display does not light up.
The telephone has failed the Self Test. Call your next level of support.
No status lights flash when the telephone is reset.
There is a problem with either the telephone base or the line cord.
Verify that the line cord is connected securely at both ends.
Other Problems
The dial tone is not audible through the handset, though
everything else works.
Verify that the handset cord is securely connected to both the handset
and the bottom of the telephone.
If you have the Privacy Option installed, remove the option and see if
the problem still exits. If not, the Privacy Option may need to be
replaced.
