DST
The transmitter is preprogrammed to automatically make adjustment for Daylight Saving Time. The letters
“DST+” (Daylight Saving Time) will be displayed when adjustment for Daylight Saving Time is active. The
letters “DST” will be displayed when adjustment for Daylight Saving Time is inactive. If neither “DST+” nor
“DST” is on the display, Daylight Saving Time is not applied. The adjustment to Daylight Saving Time and back
to Standard Time takes place at 12:00 AM on the day of the change.
Note: The GPS signal does not encode information about Daylight Saving Time. In the spring when the
transmitter changes to Daylight Saving Time, the system analog clocks will adjust by advancing faster
than their normal speed to make the adjustment and then return to normal operation. In the fall when
the transmitter returns to Standard Time, the system clock will make the time adjustment and then
return to normal operation.
Synchronous Output
The transmitter comes with two relay output terminals located in the back of the transmitter (see Figure B).
One normally open and the other normally closed, provide a relay output connection to the Synchronous
Clock System.
GPS Wireless Clock Setup
Step 1 - Remove battery cover located on the
back of the clock and put the two alkaline D Cell
batteries (provided) into the battery holder.
Step 2 - Attach the battery cover to the original position.
Receiver setup is now complete. See Receiver Operation
for details of operation.
Detailed Clock Receiver Operation
When batteries are put into the clock, the clock hands will spin clockwise and stop at 12:00:00. The clock
receiver is then activated and it will look for a signal from the transmitter. During the very first installation, the
channel stored in the clock receivers nonvolatile memory is “CH00” and it will initially look for this frequency.
The clock will scan each channel automatically and it will spend up to 1 minute searching each frequency
until it finds the transmitter.
