mc900 won't go into PL squelch

[gsmendelson]

I have an mc900 programmed for PL squelch. The problem is the radio will not use it, it is always in carrier squelch.
I've tried the obvious things, including permanent on hook setting in the rss, trying a different microphone (both with a clip on the back), etc.
The middle yellow light is on all the time, and there is a small downward arrow head under the left digit of the display (far left corner).
Pressing the monitor button causes it to beep, and holding it in turns off squelch entirely.

I do have scan set up, and with either microphone, it goes into scan.

Any ideas? Pointers to docs?

Thanks in advance.

For future reference, I found the problem.
First you have to set the "on hook" option on the radio features/misc page to match your microphone.
Second you have to set the PL tone in the PL tones page.
Third you have to select the PL on the channel options page.
Fourth, which is where I had it wrong, is you have to change the squelch type to PL on the SECOND channel options page.

I did not know there was a second page.
