You can test it out by setting it for an earlier time.....like 1:30 PM just so you can see if it works and what the alarm will sound like. I've done that before because I'd already missed one call.............didn't want to risk missing another one.

On my cell phone you have to "unset" the alarm after it's gone off otherwise it will go off everyday at that time. Yours might be different. My cell phone is a little antiquated and doesn't have all the bells and whistles most do.

My last appt with Dr. S was last week and I had my alarm all set.....I was ready to go......and they called me about an hour prior to my scheduled time to see if I'd mind taking an earlier appointment. I didn't mind and found out later that, since I had taken the earlier time slot, he'd only charged me 1/2 of what he normally does for a consultation. Bless him!
