or “ChgBat W/PowerOn” at Extensions 10 and 11
Possible Cause:
System battery power is low.

Communications Installation
guide).
Display Does Not Show Caller ID Name/Number
Possible Cause 1:
Not receiving Caller ID service from local phone company.
What to do:
Contact your local phone 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:
Extension connected to a module that does not support
Caller ID.
What to do:
Make sure lines with Caller ID service are connected to a PARTNER
ACS processor module, or 206EC, 308EC, or 400EC modules. 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 phone display.
If
Coverage Call for XX
(where XX is the extension that activated the
Call Coverage) displays, the call is a coverage call. Call Coverage displays
the extension number of the person who activated the feature rather than
Caller ID information.
