3) Insert a “AA” alkaline battery in back of movement. Follow diagram on
battery housing to make certain battery is not put in backwards. Use
only alkaline batteries as they have longer life and are less prone to
leak.*
4) Watch closely as the second hand approaches the 12:00 position.
Precisely as the second hand reaches 12:00, press and release the
red button on the back of the movement. You should hear a “BEEP”.
5) When the second hand has stepped one second past the minute hand,
press and release the red button again. You should hear another
“BEEP”. You will also notice that the second hand starts to double step
every other second.
6) While your second hand is double stepping, press and release the red
button again. This will activate the signal strength system for 20-30
seconds, in order to help you find the best installation location, were
the clock will receive the strongest signal.
When checking the signal reception, move very slowly, and follow the
guidelines below:
A).
an on-off beep every second indicates good signal reception.
This will be a good location for your clock, and the clock
should set itself to the correct time within 24-48 hours in this
location.
B) A static, or continuous beep, indicates poor signal reception.
C) No beeping indicates no signal reception at all.
