Mounting considerations
Select a mounting location, keeping in mind in the following points:
• Locate the unit away from heat sources.
• Select a location where the shock and vibration are minimal.
• Locate the unit away from places subject to water splash and rain.
• Make the maintenance space shown in the outline drawing for maintenance and
checking purpose.
• A magnetic compass will be affected if the unit is placed too close to the magnetic
compass. Observe the compass safe distances at the front of this manual to prevent
interference to a magnetic compass.
• Select a mounting location considering the length of the cables to be connected to
the unit.
• For bulkhead mounting, be sure the mounting location is strong enough to support
the weight of the unit (13 kg).
• The unit should be 4 m or more away from the VHF/MF/HF antennas.
