Software version 2.10 upgrades
This section describes several software enhancements made in
upgrading software version 2.07 to software version 2.10. Please
note that all of version 2.10's enhancements apply to each later
software version, including versions 3.12 and 3.18 as described

Anchor-watch alarm honk
In the anchor-watch alarm function, you can set the 941 to honk,
in addition to beep, as long as you've connected a honker with
pin #14 on the interface connector. Once you set the anchor-
watch alarm to honk, a continuous honking sequence begins
when either your vessel moves outside the specified anchor-
alarm radius or if the navigation source (e.g., GPS) becomes
unavailable.
Note: On the ALARMS & BACKLIGHT screen, the ANCHOR
ALARM field must be set to ON.
To set the anchor-watch alarm to honk:
1. Press the STAR key once to display the ALARMS &
BACKLIGHT screen.
2. Press the CURSOR PAD to highlight the HONK OUTPUT
field, then press the EDIT ALARM menu key.
3. Press the CURSOR PAD to select ANCHOR ALM, then press
the ENTER key.
If your vessel moves outside the set anchor-alarm radius, for the
next 10 seconds, the exclamation point begins flashing and the
alarm automatically starts beeping (you'll only hear the beeping
if you've set the ALARM AUDIO field to ON). The honk sequence
then starts for a total of 3.5 minutes: 1 second of honking
followed by 14 seconds of silence; 2 seconds of honking followed
