Re: Autohelm ST4000 Plus problems
This may not apply to your 4000+ or its firmware version, but some Raymarine instrument heads have adjustable contrast:
To set the contrast level for the ST7001 display:
1. With the autopilot in Standby mode, press the disp key for one second to
access the LAMP screen.
2. Press the disp key for one second again, to display the CONTRAST screen.
3. Use the up and down arrow keys to set the required contrast level (from
1 to 15). >/quote>
