II. BATTERY INSTALLATION
A. REMOTE TEMPERATURE SENSOR
1. Remove the battery cover.
2. Observing the correct polarity, install 2 AA batteries. The
batteries will fit tightly (to avoid start-up problems make
sure that they do not spring free during installation).
3. Replace the battery cover.
B. PROJECTION ALARM
1. Remove the battery cover.
2. Observe the correct polarity, and install 2 AA batteries.
3. In addition or instead of inserting batteries, the AC adapter can be used. Simply plug
the adapter into the receptacle on the
underneath of the alarm clock and then plug
in adapter.
4. Replace the battery cover.
5. The projector will activate and remain on if
the alarm clock is plugged in. If only batteries
are used, the projector will only be activated
when a button is pressed. The projection is a
red light, not harmful under normal usage,
although care should be taken to not look
directly into the light.
Notes:
After the batteries have been installed a tone will sound, and the LCD (Liquid
Crystal Display) will activate.
The indoor temperature/humidity and the remote temperature will be displayed.
Also, the time will appear as “-:--”.
The WWVB search is automatically initiated, and a tower icon appears and
flashes with the time colon (no tower icon will appear if the WWVB is too weak to
be detected, and the time display will remain on “-:--”).
While the WWVB search is being conducted various numbers will appear in the
time display.
After 15 minutes, the projection alarm will either display the WWVB time, or
discontinue the search if the time is not found. If the search is cancelled “-:--” will
remain in the time LCD.
The projection alarm will conduct a WWVB search every hour until the first signal
is found.
Once the WWVB time is found, a search is automatically conducted nightly at
midnight.
If the signal is found at midnight, the tower icon will remain, if not, another search
will take place every hour (until 6:00 am) until the signal is found successfully.
If no signal is found during this period, the tower icon will not appear and the
clock will search again at 12:00 am the next night.
The radio-controlled time receiver is located on the bottom side of the projection
alarm. When using the AC adaptor be sure to keep the adapter cord away from
the bottom side of the unit as if the wire is too close it can cause weakened
reception sensitivity.
