CARE
AND
MAINTENANCE
Keep the product dry.
If
it
does get wet, wipe it dry immediately. Liquids might contain
minerals that can corrode the electronic circuits.
Keep the product away from dust and dirt, which can cause premature wear
of
parts.
Handle the product gently and carefully. Dropping it can damage circuit boards and
cases, and can cause the product to work improperly.
Wipe the product with a dampened cloth occasionally
to
keep it looking new.
Do
not use
harsh chemicals, cleaning solvents, or strong detergents
to
clean the product.
Use and store the product only in normal temperature environments. High temperature
can shorten the life
of
electronic devices, damage batteries, and distort or melt plastic
parts.
Ignition
The most common source
of
noise
in
reception is the ignition system. This is a result
of
the
radio being placed close to the ignition system (engine). This type
of
noise can
be
easily
detected because it will
vary
in
intensity
of
pitch with the speed
of
the engine.
Usually, the ignition noise can
be
suppressed considerably
by
using a radio suppression type
high voltage ignition wire and suppressor resistor in the ignition system. (Most vehicles employ
this wire and resistor but it may be necessary to check them for correct operation.) Another
method
of
suppression is the use
of
additional noise suppressors. These can
be
obtained from
most professional mobile electronics retailers.
Interference
Radio reception
in
a moving environment
is
very different from reception
in
a stationary
environment (home). It
is very important to understand the difference.
AM reception
will
deteriorate when passing under a bridge or when passing under high voltage
lines. Although AM is subject to environmental noise, it has the ability to received at great
distance. This is because broadcasting signals
follow the curvature
of
the earth and are
reflected back by the upper atmosphere.
