OUT-OF-SERVICE CODES
POWER FAILURES
LOST AUTHORIZED
CALLER CODE
When the MERLIN Attendant detects a problem, the unit enters an out-of-
service state and will not answer calls. The light labeled "battery" on the front
of the unit blinks up to ten times, pauses, then repeats the pattern.
A single blink indicates that time is allocated for announcements but
NOTE:
that either no announcements have been recorded or they have been
erased.
To restore normal operation, use a straightened paper clip to press the
recessed RESET button on the back panel of the MERLIN Attendant. This
procedure does not result in any loss of programmed options or recorded
announcements. If the problem reoccurs, count the number of times
(one to ten) that the battery light blinks, then call your AT&T-authorized
technician.
Do not attempt to reset your MERLIN Attendant by adjusting the
CAUTION:
setup switches. Doing so can result in loss of programming or
recorded announcements.
When setup switches 1 and 2 on the back of your MERLIN Attendant are set
to on (down), the MERLIN Attendant can maintain all of its programming
information up to eight weeks after interruption of power. However,
recorded announcements remain only up to three hours during a power
failure (provided the battery is fully charged at the time of the power outage
and setup switches 1 and 2 are down).
If power is interrupted for more than three hours, you must rerecord all of
your announcements once power is restored.
If the default authorized caller code (789) is changed and the new code is lost
or forgotten, the default code can be restored. However this procedure also
restores all the MERLIN Plus default settings so that any programmed setting
you changed must be reentered and all announcements must be rerecorded.
To restore the default code:
1 On the back of the MERLIN Attendant, set switches 1 and 2 to off (up).
2 Unplug the MERLIN Attendant from ac power.
3 Wait 30 seconds.
4 With switches 1 and 2 still off (up), plug the MERLIN Attendant back into
its power source.
5 Reset switches 1 and 2 to on (down).
6 Using the "on-site" progr amming procedures, dial the MERLIN Attendant.
7 Dial the default authorized caller code (*789 # #).
Dial this code quickly.
NOTE:
8 Dial *990046 # # to reset the MERLIN Attendant for MERLIN Plus
operation.
9 Reprogram your settings and rerecord your announcements.
