TMQ AP4 | Revision Date: 01.07.2022 Version 10588
When the commercial timer is
enabled and the autopilot is in
control of the boat (i.e.: in AUTO,
GPS or REMOTE AUTO mode),
the AP4 internal alarm sounds after
completion of the selected interval
and the louder external alarm one
minute later, unless the timer is
previously reset.
In SET, PWR and remote POWER
modes, the timer can be set to any
required time as for a pleasure boat.

The following is a brief overview of

The AP4 can be controlled with a

or PWR

the AUTO position, move switch to
OFF and then back to AUTO.
