Rocky Mountain Radar RMR-8RDS - Manual (Page 9)

Try to avoid road splash or other liquids that can damage the
internal components and reduce the performance of the detector.
Periodically check and wipe off any dirt from the front antenna
and scrambler modules. Use a soft cloth to avoid scratching the
lens.
TROUBLESHOOTING
If the Control Module does not turn on:
Check the power cord. Be sure all power connectors are
properly installed and pushed in all the way.
Check the fuse in the power cord that goes to the cigarette
lighter socket.
The cigarette lighter socket may be dirty. Clean it with a soft
cloth to ensure a good clean connection.
There may be a problem with the vehicles electrical system.
Be sure to fully press the Power button.
CAUTION: Do not place any metal objects other than the
cigarette lighter or a cigarette lighter plug in the cigarette lighter
socket. Doing so could blow a fuse in your vehicle or cause the
metal object to become very hot.
If the remote gives false alerts when the vehicle hits bumps:
Check the vehicle’s electrical system including main battery
cable and alternator connections.
Install a filter capacitor (470uf, 35 volts) on the back of the
cigarette lighter socket across the power connection.
Verify that the front antenna and scrambler modules are not
obstructed.
Relocate the front antenna and both scrambler modules to a
clear view of the road.
Verify the cables are correctly connected to the Control Module.
FUSE REPLACEMENT
The lighter socket adapter of the power cord has a replacement
2 amp SAG fuse located below the silver tip. To check or
replace the fuse, slowly and carefully unscrew the tip of the
plug. Make sure the spring and silver tip located inside the plug
do not fly out when you remove the cap. Check fuse and replace
if necessary.
