The design of the mounting platform for the scanner should take into account the
vibration requirements defined by IEC 60945.

■ All installations should facilitate protection of equipment, including cabling, from
damage.
■ The cables should be kept as short as possible to minimize attenuation of the signal.
■ Crossing of cables should be done at right angles(90°) to minimize magnetic field
coupling.
■
Install the radar cable as far as from the cables of other radio equipment in order to
prevent other radio equipment from interfering with the radar operations. Especially
inter-wiring cables between scanner unit and display unit of the radar should not be
run parallel with the cables of other radio equipment.
■ Cable should not be exposed sharp bends.
■
Ensure that the equipment is grounded.
■ Maintain a flat level surface on which to install the scanner.
■ Use sufficiently thick steel material and reinforcement material for the scanner's
installation surface (mount base) to reduce vibration and impact. Keep the mount
base flat and smooth.
■ If there is a partial gap between the mount base and the scanner chassis's legs, work
on the installation surface so that it becomes flat and smooth, or make adjustments
by inserting metal shims.
If a gap exists and the scanner is tightly clamped, the chassis will distort and become
damaged by vibration.
■ Avoid using vibration-proof rubber and resin
■ Do not insert an elastic body, such as vibration-proof rubber or resin, between the
mount base and the scanner chassis' legs. If rubber or resin is inserted, the amplitude
of vibration increases, resulting in the possibility of damage to the scanner.
Furthermore, if installation bolts become loose due to deterioration of rubber or resin,
the scanner may be damaged or fall from its mount
