Power Requirements 

 

  This Projection Alarm Clock is powered by a 5 volt a/c power adapter  

  Alternatively, optional 2-AAA alkaline batteries may be used. 

  Half of all warranty issues can be resolved by ensuring a good power source.  

A/C Power: 

  Insert the a/c cord into the Projection Alarm properly. Line it up and push it in.  

  Check that the outlet or power strip is working. 

Note:

 Some outlets (living room, bedroom) turn off with the light switch. 

Batteries: 

  We suggest name brand alkaline batteries.  Overpowered or underpowered batteries may 

cause loss of indoor readings, missing segments, dim display etc. 

  Use batteries dated at least six years in advance of the current year. Batteries dated earlier 

than six years from now may still work, but may be unstable in performance.   

  Alkaline batteries manufactured this year will have an expiration date 10 years in the future.   

Battery technology has improved and batteries will maintain voltage longer in storage. 
However, the environment the batteries reside in for the 10 years can deplete the power. 

  Good name brand batteries make less noise, which reduces the chance of RF (radio 

frequency) interference from the battery compartment.   A minimum voltage of 1.48V for 
each battery is necessary for proper performance.  

 

Projection Alarm Clock Factory Restart 

 

  REMOVE POWER: Remove batteries and a/c cord from Projection Alarm Clock and 

transmitter.  

  DISCHARGE ELECTRICITY: Press one of the buttons on the Projection Alarm Clock at 

least 20 times to clear all memory. Verify that the Projection Alarm Clock is blank before 
proceeding.  

  UNPOWERED 10 MINUTES: Let the Projection Alarm Clock sit with power removed for at 

least 10 minutes. 

  POWER UP: Insert 5-volt A/C power cord or install fresh alkaline batteries in the Projection 

Alarm Clock.  

  If the Projection Alarm does not display the indoor temperature after 30 seconds remove the 

a/c power adapter and start the setup process again.
