Autopilot Installation
EMC Considerations & Precautions:-
All TMQ equipment and accessories are designed to the best industry standard for use in
the marine environment. Their design and manufacture conforms to the appropriate
Electromagnetic Compatibility (EMC) standards, but good installation is required to
ensure that performance is not compromised.
Although every effort has been taken to ensure the autopilot will perform under all
conditions, it is important to understand that some factors could affect the operation of the
product.
Complete installation instructions are provided in this manual. Some preliminary
suggestions follow:
Installation:-
To reduce the risk of operating problems, all TMQ equipment and cables connected to it
should be at least 1 metre (3 feet) from any equipment transmitting or cables carrying radio
signals, eg: VHF radios, cables and antennas. In the case of SSB radios, the distance
should be increased to 2 metres (7 feet).
Genuine TMQ cables should be used at all times. Cutting and rejoining these cables could
compromise EMC performance and should be avoided unless doing so is suggested in the
installation instructions.
Position of electronic compass is important to ensure no magnetic interference. It may be
necessary to trial several positions before deciding on an optimum position. Check other
side of bulkhead, dash and/or deck head for any material which may interfere with the
compass (steel or iron in particular). Keep electronic compass away from the boat’s
magnetic compass.
Check:-
Always check the installation before going to sea to make sure that it is not affected by
radio transmissions, engine starting, low battery voltage or other problems.
In some installations it may not be possible to prevent the equipment from being affected
by external influences. Usually this will not damage the equipment but may lead to
resetting of memory or momentary incorrect operation.
