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.
