I have a pair of GPM-400s, with a compact keyboard hooked up via SeaTalkng. when the system starts up (there's a switch on the dashboard that powers the system), the 2nd GPM-400 (not the master) seems to boot faster than the master, and the alarm beeps loudly for about 30 seconds until the keyboard is responsive, and then it stops.
Is there a change i can make so that it doesn't beep?
