INITIAL USE
After inst alling two AAA alkaline batter ies, the clock will display time and date. Immediately the radio signal reception is initiated and the aerial flashes. After 4 to 8 minutes, a full aerial tower shows that the MFJ-122 has successfully received the time signal and automatically set the time and date. Radio signal reception and time calibration is automatically initiated everyday at 3:00AM.
If the signal is too weak and the clock cannot receive the proper time information, reception will be terminated after 8 minutes and the aerial tower will disappear. After an unsuccessful attempt to receive the signal, the MFJ-122 will automatically attempt to acquire the signal at 4:00AM, 5:00AM, and 6:00AM. If the MFJ-122 fails to receive the radio signal, place the MFJ-122 near a window or rotate the clock in 45-degree steps. To enhance radio signal reception place your clock where minimum electrical disturbance or shielding effects are expected. Try to avoid positioning very close to TV sets or computers. The best reception time is at night when interference sources are lowest. After positioning the MFJ-122, press the
