1. Confirm the symptom and that the problem exists on all
phones. Make sure all other ELAN phone features are working
properly.
2. Verify that the Door Station is properly connected to the
Door Station bus on the COM2, and the connector is plugged
snugly into the Door Station jack. Verify proper DIP switch
settings on the Door Station. If the problem still exists, there
may be a problem with the COM2 or Door Stations. Contact
ELAN Technical Support from the job site at 1-800-622-ELAN.

Speaker
microphone
and/or Door
Station Output
levels are too
high.
1. Confirm that problem occurs on all phones.
2. If the problem is specific to only one phone, it is likely that
the mic sensitivity of that phone is incompatible with ELAN
3. If the problem occurs on all phones, it is probably due to
feedback between the Door Station mic and speaker. There
are two ways to alleviate this. We suggest that you try (a) first,
as it will not result in any loss of Door Station mic or speaker
levels:
a. Stuff the Door Station rough-in bracket with insulation
b. On the front of the COM2, find Door Station Microphone
Input Level Adjustment control and turn it counterclockwise.
Test Door Station communications. If this did not eliminate
the problem completely, locate the Door Station Output Level
Adjustment control and turn it counterclockwise. Test Door
Station communications.
If problem still exists, call ELAN Technical Support at 1-800-
622-ELAN.

Verify the correct connections for the doorbell, (see Chapter 3
