Set up an Automatic Setting Analog Clock
To set up an Automatic Setting Analog Clock, apply power to the clock and it automatically initializes its setup and searches for a
signal from Transmitter to receive its time.
WARNING
Battery-powered clocks: for sites with multiple Transmitters or repeaters it's important that batteries are inserted when the
clock is at its permanent installation location.
Clock signal search frequency - time update
A clock's search frequency is when its receiver turns to search for a Transmitter signal, starting with the previously stored
channel, to receive a time update. When a clock is first powered on, it automatically initializes its set up and searches for a signal
to receive its time. The only model that requires a specific setup is a Manual Setting Analog Clock.
The scheduled search frequency varies by clock model as defined below.
Analog Clock signal search frequency: six pre-scheduled times a day at 10:01, 2:01 and 6:01 a.m. and p.m. lock time (not the
actual time of the day), a clock's receiver turns on to search for a Transmitter signal to receive a time update, starting with the
previously stored channel number.
Digital Clock/Timer signal search frequency: every 10 minutes on the 5's (5, 15, 25, 35, 45, 55 minutes) of the hour, a clock's
receiver turns on to search for a Transmitter signal to receive a time update.
When a clock has not received a valid signal/time update for three consecutive days, it displays a visual signal loss indicator; an
analog clock's second hand advances and pauses continuously (stepping) and a digital clock/timer's colons flash.
Transmitter broadcast schedule
The type of antenna determines a Transmitter's broadcast schedule, which should be taken into consideration when installing
new system devices. System devices receive a time update during its scheduled signal search or when powered on from a
broadcasting Transmitter.
Broadcast (Transmit) Schedule Transmitter with Internal Antenna: broadcasts its synchronized time continuously to the system
clocks and devices.
Broadcast (Transmit) Schedule Transmitter with External Antenna: broadcasts its synchronized time to the system clocks and
devices from the 39th to the 6th minute of the next hour and changes to a standby mode during the 7th to the 38th minute of the
hour (standard broadcast schedule). During initial power-up, the Transmitter broadcasts for 8 consecutive hours. After the 8 hour
power-up period, the Transmitter reverts to its timed broadcast schedule.
NOTE
In the event of a facility wide power outage, a Transmitter with an External Antenna will broadcast for 8 hours upon the
