Automatic Speed Selection; Manual Speed Selection - Simrad AP35 Instruction Manual

Simrad AP35 Autopilot

2.10 Automatic Speed selection

The AP35 provides two different sets of steering parameters for controlling
the response of the boat at different speeds (HI or LO) while in AUTO and
NAV modes.
The AP35 always selects the HI speed steering parameters when first
switched on. This is a safety feature. After initial turn on, selection of the
steering parameters is done automatically, based on the availability of input
data from either an external speed log or an external navigator, or manually.
The AP35 automatically selects the HI or LO parameter set. The speed at
which the AP35 changes from HI to LO (or opposite) is determined by the
"Transition Speed" set in the Installation Setup Menu.

2.11 Manual speed selection

Select AUTO mode. To toggle between HI and LO speed parameters, press
the "AUTO" button two times quickly (Double click).
If you change boat speed it is recommended that you select HI or LO
parameters correspondingly.
The manually selected steering parameter set (HI or LO) will remain in
effect until you re-enter AUTO mode or restarts.
