RANGERs are shipped with a fused cigarette lighter plug.  The fuse is housed inside the tip of the 
plug.  (See arrow in below illustration.)  To remove fuse: unscrew and remove the tip and the fuse.  
Replacement fuses should be commonly available 2 Amp, AGC type fuses.  Substitutions are not 
recommended and may violate the RANGER's warranty. 

 

 
The RANGER wireless remote uses 2 AA disposable alkaline batteries.  These require periodic 
replacement by the user.  A typical set of batteries should last approximately six months, as long 
as the remote control is not stored in a manner in which one of the buttons is inadvertently 
depressed for a significant period of time.  The first indication that the batteries need replaced will 
be a reduced range of the wireless remote and a need to point the control toward the radar.  In the 
case of totally dead batteries, the radar unit will go through its self-test when plugged in, but not 
respond to commands from the remote.   
 
The batteries are changed as follows: 
 

•

  On the back side of the remote, slide the ribbed retaining latch of the battery cover down.  

The latch may be difficult to slide the first few times the batteries are replaced. 

•

  Carefully pivot the battery cover off of the remote, trying not to damage the guide hooks 

on the bottom of the battery cover. 

•

  Remove the batteries and replace them with new alkaline batteries 

•

  Carefully replace the battery cover, inserting the guide hooks into the housing first and 

then pivoting the cover back into position. 

•

  Slide the ribbed retaining latch up to lock the battery cover.
