2.2 ST7000/6000 Control Unit
The ST6000 and ST7000 control units are identical in operation and
installation.The main ST7000/6000 control unit should be mounted close
to the steering station where it is:
• normally viewed straight on for the best display legibility
• well protected against physical damage
• at least 9in (230mm) from a compass
• at least 20in (500mm) from radio receiving equipment
• accessible from behind to install and run cables
Note:
The rear case is designed to breathe through a small duct in the
cable boss to prevent the accumulation of moisture. Direct exposure to
the rear of the control unit must be avoided.
