Manual of Radio Controlled Clock Movement

Step 1
Attach the motor to the clockface according to the diagram.
Step 2
Install the hour, minute, and second hands parallel to the 12 o’clock position and keep the distance between the hands.
Step 3
Pull out the positioning pin behind the motor.
Step 4 Insert the battery (AA, 1.5V, LR6) into the battery siot (ensure the polarity of the battery Is correct). You will see the second hand returns to zero, and the minute-hand sweeps to 12:00 and then enters the receiving state. This process takes 3-15 minutes. After receiving the current time, the hands will automatically adjust to the correct position the clock will function normally.

Summary:

The clock receives radio waves to automatically synchronize to the current time. The main feature ts that the time ts always and it will self-cocrect any time error (When the ACC switch bs set to the ON position, it has a radio wave reception function. if it ts set to the OFF position, radio wave reception ts not performed. This function is only available for the U.S. version).Due to the strength of the radio signal in each area, if the above operation does not receive the signal, remove the battery, and then repeat the
instaliation of the battery after 20 seconds; if the signal is not received after 15 minutes, move the clock in front of a window to receive the signal again. R can be used normally after receiving the signal.
Manual time adjustment:
The time can be adjusted manually while the clock is running. Press the SET key for more than 3 seconds, all the hands stop, the minute hand moves 6 times (that Is, | minute), and it enters the manual time adjustment mode . When the SET button is pressed for more than 1 second, the hour and minute hands will move quickly; if the SET button is pressed shortly (less than 1 second), it will increase by 1 minute. if the user does not operate the SET button and the REC button, after about 30 seconds, it will automatically exit the manual time adjustment mode and enter the normal timekeeping mode.
Reset:
Press the reset button to clear all the clock’s internal information. The hour, minute, and second hands are reset to 12:00, the radio wave signal will be received. if the signal reception is OK, the time will be Automatically Calibrated, This needs to be dlarified.normal functioning will restart after the time calibration ts completed.
Automatic reception of radio signals and automatic hand correction function:
When the hand position of the clock is inconsistent with the internal time for any reason, the clock automatically detects the hand position in several time periods and corrects it to be consistent with the internal time. in order to compensate for the clock’s quartz crystal error, the clock’s time will be automatically received 4 times a day, corresponding to the morning: 3:00, 4:00, 5:00, 6:00, in order to correct any time error to ensure the radio dock’s time accuracy.
Calibration of the second hand, correction of the minute hand
At 1:30:00, 9:30:00, and 17:30-00, the position of the second hand is detected, and then compared with the internal time and recalibrated as needed. After 3 minutes, it will exit the calibration process. At 1:52:00-2:00-00, the position of the minute hand is detected, and then compared with the internal time. If the deviation is greater than half a minute or more, it will be reset to 12:00:00 and then forced to receive radio time calibration. Check this. Needs to be clacified/rephrases. How is this issue corrected/resolved?
