4. Insert two alkaline batteries into the battery holder. It is essential that fresh, superior-quality batteries, with an
expiration date that exceeds five years past the installation date, be used for the system clock.
NOTE: Be sure to insert the batteries with the battery "+" end to the "+" end of the battery holder.
5. Once the batteries are properly inserted, the second hand will begin moving one step every second.
6. When the second hand gets exactly to the "12" position, press and release the button. The system clock will beep
twice.
7. Wait until the second hand crosses the minute hand and is precisely at the minute mark that the minute hand is
moving to, then again press and release the button.
The clock will beep twice and then the second hand will start to double step every other second. The clock will
l
continue to double-step every other second until the clock receives and decodes a valid time signal from the
transmitter.
The clock should receive the signal between 1 second and 45 seconds after the above procedure is complete.
l
Once a valid time signal has been decoded, the system clock will either advance at eight times normal speed or
l
it will slow down to half normal speed until the hands display the accurate time.
Once the clock has decoded a valid time signal from the transmitter, the clock will beep and continue to beep
l
with every valid decoded signal for the next minute.
