I have model 1104 sensaphone and lost manual. I want to know how to change dial out numbers

To change the phone numbers in the Sensaphone 1104 press [SET] [phone number] <1-4> then enter the telephone number you want the unit to dial, and press [enter]
*Remember to program the telephone number JUST how you need to dial it from that location. If you do not require a 1 or area code do not program it in, as this can cause the dial out to fail.*

Here is a link to the manual if you need one. Also, since this model was discontinued, the direct replacement for this unit would be the Sensaphone 400.
