The Radio Information Board

I have a friend that uses an EF Johnson 5317 mobile for Civil Air Patrol. He was set up on a channel for CAP, made one transmission, keys down, and hears 3 beep tones before the unit transmission occurs and he wants to know why. He is physically handicapped and has trouble seeing smaller print. I while also search for an on-line manual, but in the meantime if anybody knows the significance of the 3 beep tones it would be greatly appreciated.

This, by the way, is a URL for the manual http://www.squadron282.com/resources/manualefjohnsonmobile.pdf

The reason for the beeps could me multiple but here are my thoughts
1. If this is programmed for use on a trunking system then you may be hearing the 'go ahead' or 'talk permit' tone
a. Because this is a CAP radio I doubt this is it
2. The radio could be programmed to do some sort of Pre TX ANI (probably DTMF)
3. There could be an over/under voltage issue with the radio (it will be indicated on the display)

I.S.

Someone (probably) pressed the button to put it into crypto mode and the radio was not set up for that. Pass him along this cheat sheet that will put the radio into a working condition. Excuse the formating. Cut and past this into a text editor and change it to monospaced fonts so it looks right.
Or message me and I'll send a PDF.
