Section 1: Short Operating Instructions.
These Short Operating Instructions provide a quick reference guide to setting up and
operating the NT888G MK2 Autopilot. The locations in the manual where more
detailed descriptions can be found are shown against each heading in brackets, e.g.

1.1
Control Unit Display Data & Initial Control Settings - (Section 2.4).
The NT888G MK2 Autopilot is Speed Adaptive and – provided it is used in adaptive
mode and calibrated for the correct vessel type (DISP or HSC per 2.16) – will
automatically set its own control parameters for optimum steering performance.
Adaptive/non adaptive operation is selectable via
CONTROLS
key operation and
entry to the
Controls Menu
which is shown on the right of the main display.
Unless alternative settings have been established from experience during sea
passages with the Autopilot in operation, selection of the non adaptive mode will be
necessary to enable primary control settings (YAW, RUDDER, COUNTER RUDDER)
to be manually adjusted.
If conducting first time sea trials or - if unfamiliar with NT888G MK2 Autopilot
operation – see section 2.4.

Autopilot is engaged (“ON” key operation).
