Display Shows Only 16 Characters Per Line
Possible Cause: Processor module is not R 4.1.
What to do: Check the release number on the processor module.
■ If the processor module release number is lower than 4.1, the display shows a
maximum of 16 characters per line.
■
If the processor module release number is 4.1, unplug the modular telephone cord
from the phone then plug it in again. If the display is still incorrect, see “System
Phone Does Not Work.”

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: Wrong 206 and/or 400 module installed in the control unit.
What to do: Make sure lines with Caller ID service are connected to 206EC or 400EC
modules.
■
If Caller ID lines are not connected to 206EC or 400EC modules, install the
appropriate modules and/or make the appropriate connections.
■
If Caller ID lines are connected to 206EC or 400EC modules, go to Possible Cause 3.
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 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.
If “Coverage Call for XX’ does not display, call the hotline.*
