MD-550

SAFETY INSTRUCTIONS

CAUTION
The mounting location should satisfy the following conditions: Sparate from radio transmitter, radar, direction finder (at least 3m). Locate the equipment away from air conditioner vents. Keep the equipment out of direct sunlight. Vibration should be minimal. The location should be free of water spray. Do not install this unit on the overhead. Do not use the cable having a diameter greater than 11.7 mm.
Ground the equipment cable armor to prevent mutual interference and electrical shock. Observe the following compass safe distances to prevent deviation of a magnetic compass: Standard compass MD-550 1.40 m Steering compass 0.95 m
Turn off the power switch at the switchboard before beginning the installation.

Cables

Use the following cables (Japan Industrial Standard cables) or the equivalents.

Mounting

This unit has not power switch. If you do not connect the MD-550 to power switchboard or circuit breaker, install an external power switch (local supply), locating it near the MD-550.
