Wiring
· Keep autopilot connection cables away from radio aerials and cables

Compass Installation
There are three types of compass suitable for this autopilot - a TMQ compass-top sensor
(CTSB), a TMQ fluxgate compass (COMMAGB) or TMQ electronic compass
(ELECOM)
Installing a Compass-Top Sensor
A compass top sensor should be used as the pilot heading reference unit for steel boats.
Before attaching the CTSB to the top of a flat top compass, ensure there are no defects in
the compass, eg: sticking card, as this will affect the operation of the autopilot. Also, the
compass should be compensated.
Position
· Firstly determine the correct position of the CTSB on the compass glass top
(CTSB is central on the top and cable facing aft)
· Route the cable to the AP9 control unit position
