7
times, again at 4:00 AM and at 5:00 AM. If the unit fails to receive the RCC signal at
5:00 AM, it will not automatic enter the RCC receiving mode again until 2:00 AM on the
following day. The RCC receiving period for this unit is around 7 minutes.
NOTE:
Please check the following if you are having problems getting the clock to set
automatically:
If you are using batteries, check them and replace if necessary.
Try rotating the main unit 90 degrees or relocate it to another location opposite
where you have it placed. The antennas are directional and you might be able to
improve the signal strength by turning the antenna.
Place the SFA2650 along a wall or near a window that faces the source of the
broadcast (Fort Collins, Colorado).
Relocate the clock at least 3-6 feet away from any computer monitors, which can
cause interference (some monitors have a scan frequency at or near the WWVB
carrier frequency of 60 kHz).
If nothing else works, take the clock outdoors at night and power it down (remove
the batteries and unplug it), then power it up again to force it to look for the
WWVB signal. If the unit works outdoors but not indoors, you probably have a
local interference problem inside your house or building.
The shielding provided by a metal building might prevent the clock from working.
For example, if you live in a mobile home or a house with steel siding, the clock
might not work because the signals are being blocked.
RCC reception icons
1. When the unit enters RCC receiving status, the RCC indicator (tower-shaped icon) (#4)
will flash on the display.
2. When unit is receiving the signal, the RCC indicator (#4) and the RCC receiving indicator
(#5) will flash.
3. If RCC signal is too weak to be received, the RCC indicator (#4) keeps flashing but the
RCC receiving indicator (#5) will not be displayed.
4. If the unit received the synchronization signal, the RCC indicator (#4) and the RCC
receiving indicator (#5) will both be displayed solid and exit the receiving mode.
5. When the unit fails to receive the signals in a day, it will receive the signal again at 2:00
AM on next day. To exit the RCC receiving mode, press the
“DOWN/TIME ZONE” button.
The RCC indicator icon (#4) disappears from display.
6. During the receiving of the RCC signal, if the alarm sounds, it will exit RCC receiving
mode first and change to alarm mode.
7. When received a DST signal, the DST indicator will appear on display.
