Care and Maintenance
Caution: Using a fuse that does not meet this requirement can
damage your detector, the power cable, or the vehicle's electri-
cal system.
1. Turn the knurled ring on the cigarette-lighter plug counter-
clockwise to unscrew it.
Caution: If you must use pliers to loosen the ring, be care-
ful not to crush the ring or the metal tip inside the ring.
2. Remove the ring and tip from the power cord’s cigarette-
lighter plug, then remove the old fuse.
Note: Take care not to lose the ring, tip, or the spring inside
the plug.
3. Check the fuse. If it has blown, replace it.
4. Replace the metal tip inside the ring, making sure the
spring is intact, then place the fuse inside the cigarette-
lighter plug and screw the ring back onto the plug. Make
sure the tip is visible when you reassemble the cigarette-
lighter plug.
