Chapter 1: Operation
1.1 Getting started
This handbook describes how to operate, maintain and install the Raymarine
ST60+ Compass instrument. The Compass instrument shows both compass
heading and steering indication. Where GPS or similar positioning data is
available from another instrument, Course Over Ground (COG) is calculated and
can be used to provide a true course display.
Switching on and off
All the time that power is applied to the instrument, you can use the disp button
to switch the instrument off and on as follows:
• To switch the instrument off, hold down the
disp button for approximately
5 seconds. After this time, a switch off count down of 4 seconds occurs. Keep
the
disp button pressed during this period, to switch off the instrument.
• To switch the instrument back on, hold down the
disp button for approxi-
mately 1 second.
When the power supply is switched off, none of the instrument buttons (including
disp) has any effect.
Notes: (1)
Each time power to the instrument is switched on, the instrument is ini-
tially in the on condition. You do not need to use the
disp
button to
switch the instrument on.
(2)
When the instrument is on, the operation of the
disp
button will perform
other operating functions, as described below.
Calibration alert
If the CAL legend on the digital display flashes for the first 30 seconds after any
power up, use the appropriate procedures in
Chapter 4, Calibration
to:
1. Apply the factory defaults.
2. Carry out the linearization procedure.
