8.4 Selecting the Display UnitLocation
The SL70 and SL70RC PLUS LCD display units are waterproof to CFR46
and can be installed either above or below deck. The display unit can be
mounted using the mounting bracket supplied, or console mounted using the
optional flush-mounting kit.
The dimensions of the display unit, including the bracket, are shown in
Figure 8-6 .
When planning the display installation, the following should be considered to
ensure reliable and trouble free operation:
• Convenience: the display unit should be mounted in a convenient posi-
tion, where it can be viewed straight-on or with a viewing angle of less than
35
°. Power the unit and select a suitable mounting location prior to install-
ing the display.
The mounting location should be easily accessible to allow operation of
the front panel controls.
• Access: There must be sufficient space behind the display to allow cable
connections to the rear panel connectors, avoiding tight bends in the cable.
• Interference: The selected location should be far enough away from
devices that may cause interference, such as motors, generators and radio
transmitter/receivers (see the EMC guidelines earlier in this section).
• Magnetic compass: Mount the display unit at least 3 ft (1m) away from a
magnetic compass.
• Cable runs: The display unit must be located near a DC power source. The
power cable supplied is 4.9 ft (1.5m), but a longer cable can be used if
required: refer to Section 8.3.
The maximum length of cable between a display and the scanner unit
should not normally exceed 60 ft (20 m). If you need to use a longer cable,
refer Section 8.3.
• Environment: Do not restrict airflow at the rear of the display unit.
Ventilation is required to prevent the unit from overheating.
The display should be protected from physical damage and excessive
vibration. Mount the display in a protected area away from prolonged and
direct exposure to rain and salt spray.
