Then it begin to access to initial re-
ceiving time signal, it takes maxi-
mum 10 minutes. If receiving
successfully, the hands will find the
correct time and work normally.
(Running condition after the OK re-
ceiving).
The dealing of the initial
failed receiving
If the signal is bad, and the RCC si-
gnal can not be received within 10
minutes the clock will exit receiving
and start to timing from the position
12:00:00, but then every breaking
hour the hands will stop running
and start receiving signal, If within
10 minutes, receiving signal the
hands turn to the position 12:00
and forward the correct time work
normally.
If the receiving above is failed again,
the clock will forward the MCU time
and work until it receives RCC signal
or repeat 15 times failing receiving,
the clock exit the hands stop at
every breaking hour, then enter into
the auto-force receiving.
From that time, the clock will enter
into one time auto-force receiving
at AM3:00 every day and the hands
will stop working at that time.
If only the above any receiving is
OK, the clock will update the MCU
time, the hands turn to the position
of 12:00 firstly, then forward the
correct time and run normally.
The timing state of receiving OK
---Auto-adjustment receiving
everyday
Under the normal timing state (after
receiving OK), the clock will auto-
receive the signal to adjust time 9
times per day, only adjust the se-
cond difference need at most 10
minutes, it will update the MCU time
,the auto-receiving time is as fol-
lows:
Receiving time: AM 1:00,2:00,3:00,
4:00,7:00, 11:00
；
PM 3:00, 7:00,
11:00.
During the above receiving, the se-
conds will stop at 20s for 2~20s.
When the clock runs to AM2:00,
3:00, 4:00, during the 3 times re-
ceiving signal which detect the hour
difference (the signal time with one
hour difference from the clock
time).
The hands will stop timing and enter
into the auto-force receiving.
(The receiving action same as Force
Receiving function).
If in the 9 times of auto-receiving, 6
times repeat auto-receive without
signal, the auto-receive will stop,
and the clock run to AM3:00 the
hands stop, then enter into force-
receiving.
(The receiving action same as Force
Receiving function).
Manual setting
Under the normal running condi-
tion, press M.SET button greater
than or equal to 3 seconds, the se-
cond hand stop and the minute run
fast.
Then the clock enters into manual
setting. Press M-SET button, the mi-
nute hand will run fast and when
you set free the button, it will stop.
Press the button each time, the mi-
nute hand goes one minute. If don't
press the M.SET button within 7 se-
conds, then exit the manual setting
function, and the clock run at the
set time.
