Maintenance
Fuse Replacement
Ranger EZ radars 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.
Remote control batteries
The Ranger EZ 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.
