Replace Batteries - Automatic Setting Analog Clock

Complete the steps below to replace the batteries for a Automatic Setting Analog Clock.
1. Remove the clock from its location to access the back of the clock.
2. Remove the old batteries, wait 10 seconds.
3. Insert two new alkaline batteries.
NOTE: It is important to insert the batteries with the battery '+' end to '+' end of the battery holder to achieve proper
battery orientation.
When both batteries are in place, the clock automatically initiates the Self Initialization procedure to set its time.
Automatic Setting Clock Self Initialization Overview
After the batteries are inserted, the clock's receiver will begin to step through all channels, searching one channel every 5
seconds, scanning for a valid time signal from the transmitter.
Once a valid time signal has been received, the clock will AUTOMATICALLY set to the correct time as follows:
1. First, the second hand will step at eight times its normal speed until it finds the 12 o'clock position.
NOTE: The minute hand and second hand may take turns stepping while the second hand is moving to the 12 o'clock
position.
2. After the second hand is set to 12, the minute hand will begin to advance around the dial quickly towards the
correct time.
3. As the hour and minute hands advance toward the correct time, the hands will pause for about 5 seconds at a
displayed hand position of either 4, 8 or 12 o'clock, whichever of these positions falls just before the actual time.
4. After the hands pause, the hour and minute hands will proceed to advance quickly until the correct hour and
minute are reached.Once this occurs, the second hand will then step at eight times its normal speed until it
reaches the correct time. It will then continue to move once per second. The time displayed on the clock should
match the time displayed on the transmitter and the clock will operate normally.

Automatic Daily Transmitter Signal Check - Automatic Setting Analog Clock

At six pre-scheduled times a day (at 2 am/pm, 10am/pm, and 6 am/pm clock time, not actual time), the clock receiver
automatically turns on and begins searching for the transmitter signal, starting with the previously stored channel
number. If no signal is received on the first channel, the clock will scan all channels, searching for a signal.
If the clock has not decoded a signal from the transmitter for four straight days, the clock second hand begins to step
twice at two second intervals to call attention to a problem with the clock. This pattern is repeated and the clock displays
the correct time, but it is not synchronized and its time may drift. This two-second stepping pattern continues until the
clock receives a valid time signal from the transmitter. Once a valid time is received, the clock hands are set to the correct
time and resume moving normally.

Automatic Midnight Verification

Every day at midnight, the clock checks to ensure that the position of the hands are correct and will automatically correct
the hands if they are off. This resetting of the hands is the same as the Hand Alignment Check and Self Initialization
procedure.
