Fuse Replacement

. If the fuse has blown, remove the tip from the lighter plug
followed by the old fuse. Replace the fuse with a 1-amp, 3AG
fuse. Defeating the fuse protection can damage your unit or
your vehicle’s electrical system and will void your warranty.
Note—the tip is in two pieces; be careful not to lose either piece
or the spring inside the holder. (See diagram above).

Three Radar Frequencies
Three microwave frequencies have been allocated by the fcc
(Federal Communications Commission) and are used for
traffic Radar. They are:
X band: 10.525 gh
z
K band: 24.150 gh
z
Super Wideband Ka: 33.4 gh
z
to 36.0 gh
z
Both X and K bands are well known to motorists who have
traveled with Radar detectors. Introduced first was X band
Radar which became common during the 1960s. In the mid
1970
s the lower powered, more difficult to detect K band Radar
was introduced. In 1987, fcc approval was given for Radar
equipment using a third frequency, Ka. In response to this,
beltronics
introduced the first Radar detectors capable of
detecting X, K and Ka band signals. In late 1990, fcc approval
was given to Wideband Ka: 34.2 gh
z
to 35.2 gh
z
. Once again,
bel
responded with Wideband Ka detection. Today, the
bel 980
and bel 950 detect the complete Super Wideband Ka
frequency allotted for police monitoring—33.4 gh
z
to 36.0 gh
z
.
