I must have something set wrong, but I can't figure out what.

The switch is set to ring, not vibrate. In preferences I have the 'sound mode on' volume set to 7 and the alarm tone set to 'alarm', 'play sound ' set to 10 times 'repeat alarm' as 3 times and 'alarm preset' as 1 minute. The calendar shows the little alarm symbol, but when the time coems nothing happens. The screen doesn't change, nothing.

It does the same thing whether the Treo is active or in "shutdown" mode

TIA

Take care,
Rich
