1 1

What to do: Re-enter the date, day, and time using System Date (#101), System Day (#102), and
System Time (#103).
■
If the display is correct, the problem is solved.
■

or “ChgBat W/PowerOn” at Extensions 10 and 11
1 1
Possible Cause: System battery power is low.
What to do: Replace the system batteries (see “Inserting Batteries in the Processor Module” on
page 2-11 ).
Display Does Not Show Caller ID Name/Number
1 1
Possible Cause 1: Not receiving Caller ID service from local telephone company.
What to do: Contact your local telephone company to check on Caller ID service.
■
If you are not receiving Caller ID service, subscribe to it.
■
If you are receiving Caller ID service, go to Possible Cause 2.
Possible Cause 2: Line connected to a module that does not support Caller ID.
What to do: Make sure lines with Caller ID service are connected to a processor, 206EC, 308EC,
or 400EC module. If Caller ID lines are not connected to one of these modules, install the
appropriate modules and/or make the appropriate connections.
Possible Cause 3: Someone activated Call Coverage.
What to do: Check the system telephone display.
■
If
Coverage Call for XX
(where XX is the extension that activated the Call Coverage)
appears, the call is a coverage call. Call Coverage displays the extension number of the
person who activated the feature rather than Caller ID information.
■
If
Coverage Call for XX
does not display, call the helpline number listed on the front, inside
cover.
