ComNav P4 Installation and Operation Getting Started
Document PN 29010100 V1r0 - 101 -
Reset
A full reset of all the P4’s operating parameters will be initiated when the ENTER button is
pressed and held until the
word “Reset” changes to upper case “RESET.” This change
indicates that a full reset has been completed.
Resetting means that any configurations you have set (including Compass and Drive
Setup), as well as all
parameter adjustments you have made, will be lost. You should use
the full-reset option only on the advice of an authorized
ComNav service representative.
Caution! A “full reset” means that ALL of the parameters in the entire autopilot system
will
revert back to the default settings installed at the factory. All custom information will be lost.
Vessel Type
Set the vessel type to match (as closely as possible), the kind of craft that the autopilot is
being installed on.
The system then automatically selects a specific set of equations and
constants – for use in the
P4’s steering algorithms – which have been found to work
reasonably well with typical craft
of the chosen type. Also selected are the initial values of
the Steering Parameters used in
those equations (see the Sea Trials and Auto Menu
sections for more details).
NOTE: during Sea Trials, and later in normal operation, you can adjust any or all of
the
Steering Parameters’ values, to better suit your own vessel, and/or the current
sea
conditions.
Choose this for planing-hull boats with
outboards
or stern-drive legs.
Choose this setting for full displacement
boats that
do not plane or rise out of the
water at cruising
speed.
Choose this if your boat rises partially out
of the
water at cruising speed.
Large, with a slow
Helm response
Vessels in this category are typically
over 125’
LOA and/or 100 GRT (e.g.,
freighters, tankers,
dredgers, car/truck
ferries, fish processors, etc.).
