The unit can store up to three phone numbers, phone1, phone2, phone3. Programming the numbers is simple, you’ll just send a text message to the number given during activation (once you have it save it to your contacts for future use). For example, if you wanted to program 555-555-5555 as your first number you would send a message exactly as it appears below:
Note: To program a phone number into the unit’s phone 1 slot, you must start the message with the word phone1. To program the second and third numbers you’ll simply use the words phone2 or phone3, respectively, in place of phone1.
When the unit receives the message, it will chirp twice and then it will respond with a text message that contains the current settings. You should wait for the text message response on your phone before proceeding. If an error occurred while processing your text message, the alarm will beep 3 times.
