Initial Start-Up
After inserting new batteries into the MFJ-124, the clock will automatically begin searching
for the radio signal. The LCD display (6) will initially read:
•
L:0~5: This indicates the strength of the signal received. Level 5 indicates the
signal strength is OK. Levels 0~4 indicate the signal is weak.
•
00~59: seconds counting.
•
OFF: Alarm off mode.
•
The receiving tower symbol will begin to blink. This indicates the MFJ-124 has
entered the time signal receiving mode.
If the MFJ-124 has received and locked into the signal, the tower symbol will stop
blinking and remain steady. The LCD display (6) will show the correct time and continue
working. The MFJ-124 will search for the time signal four times a day to auto-adjust the time
and date.
If the MFJ-124 is out of the signal area and cannot receive time signal, the MFJ-124 must
be set manually. Please follow the instructions under Manual Time Setting.
