When the clock time matches an event time and that day is set to “
ON
” or “
A
”, the
CTG-1
will output the corresponding sin-
gle, double or triple bong or buzzer alert tone. The
CTG-1
will also open terminals 3 and 4 (normally closed) and close ter-
minals 4 and 5 (normally open), allowing the capability of switching out the audio from the phone system and switching in
the alert tone from the
CTG-1
. Similarly, while a contact closure is made shorting pins 9, 10 or 11 to pin 12, the
CTG-1
will
output the corresponding sound (doorbell, evacuation signal or emergency siren). In the case of the siren or evacuation
signal, terminals 3 and 4 will open, and terminals 4 and 5 will close and the sound will continue for the duration of the con-
tact closure input. Terminals 3, 4 and 5 will return to their normal states at the end of each doorbell tone.
Note:
Terminals 6, 7 and 8 will operate the same as terminals 3, 4 and 5 but are electronically isolated from terminals 3, 4
and 5 for switching a separate device.
IMPORTANT:
While operating, the
CTG-1
continuously checks the event time information stored in memory. If a problem
is detected, the
CTG-1
displays “
EEE
” to indicate an error. Normal clock function continues in the background. To clear
the error, press any button and the
CTG-1
will return to normal operation. If the “
EEE
” display persists, contact Viking
Technical Support at 715-386-8666.

. Unplug the
CTG-1
from power. Pause a few seconds and then plug the
CTG-1
back in. Push
the
CANCEL
and
SINGLE
buttons at the same time and release them. Repeat, and after releasing the buttons the sec-
ond time a long beep will be heard indicating that the
CTG-1
’s memory has been cleared. Turn DIP switch

to enable battery backup.
Note:
After completing this procedure, it will be necessary to reset the clock time (see
Programming
section
A
), and
if enabled, the day of the week (see
Programming
section
B
) and alert tones on/off (see
Programming
section
C
).

Unplug the
CTG-1
from power and turn DIP switch 1
OFF
. Remove the shunt as shown in the diagram above to change
from 60 Hz to 50 Hz, or replace it to change from 50 Hz operation to 60 Hz. Power the
CTG-1
back up and turn DIP
switch 1
ON
. Set the
CTG-1
to the current time.
