Or

Alarm clock

Open the alarm clock tab.

To set an alarm, select Options > Set alarm. When an

alarm is active, is displayed.

To switch off the alarm, select Stop, or to stop the alarm

for 5 minutes, select Snooze. If the alarm time is reached

while the device is switched off, the device switches itself

on and starts sounding the alarm tone. If you select

Stop, the device asks whether you want to activate the

device for calls. Select No to switch off the device or Yes

to make and receive calls. Do not select Yes when wireless
phone use may cause interference or danger.

To change the alarm time, select Options > Reset

alarm.
To remove the alarm, select Options > Remove alarm.

Good luck please rate 4 thumbs up and please leave a testimonial.

i am having a nokia 1100, alarm and reminder are on on mode. however it is not making any sound. 

After several iterations with only time/chime/chronometer showing up, my husband hit mode, got chime, hit start stop and suddenly there was Alarm 1. We have yet to get Alarm 2 but hope to some day.

It sounds like you have an alarm set to switch on the phone at a set time and/of day, (or several alarms).

"Beulah, peel me a grape"

The Alarm overides the Profiles. If you don't want an alarm to sound, don't set it. There is no point in setting an alarm if you don't want it to ring. Set the Alarm warning tone! to Vibrate.

try to check the warning alerts, if is in the no sounds mode,
change it in to yes...

try dropping power to the unit for a minute and see if it will reset itself. if not, you have a logic board failure. that or a door switch. check the manual for an indication on the warning alarm.
good luck
