Setting the time
Through lens:
Using a small, thin object such as a pen or hairpin, press “set” buttons through front lens access holes. If
the access holes are on the right side of the lens, then the top “set” button advances hours and bottom “set” button
advances minutes. If the access holes are on the bottom of the lens, then the left “set” button advances hours and
the right “set” button advances minutes.
Remote switches:
Some systems may have two push button switches for setting the time. These switches can be mounted
anywhere for easy access. They are provided on system where the holes in the lens may not be accessible. The
switches are just momentary push buttons, a press and release will either advance the hours or minutes. The
BLACK “set” button advances hours, the RED “set” button advances minutes. Each time that you make a change
to either the hours or minutes, the seconds are reset to zero.
Adjusting the accuracy:
The clock is accurate to +/-2 minutes a month as it is set, but it can be tuned for better accuracy if desired.
Press and hold both of the set buttons for several seconds. The clock will display “C 0”. The “C” indicates that it is
in the calibration mode and the second number is the current calibration value. The calibration value indicates the
number of seconds to add or subtract each day. The clock can be adjusted from +7 sec/day to -7 sec/day.
Press the minute set button to change the cal value. Press the hour set button to return to normal clock
operation.
