Can a Refrigerator/Freezer Guard and an answering machine or fax machine share the same line?
Yes. To have the answering/fax machine answer the phone, program the Refrigerator/Freezer Guard to answer the phone on the 5th ring. To access the Refrigerator/Freezer Guard, call the number and let the phone ring 3 times. Hang up and wait 20 seconds. Call the number again and on the 2nd ring the Refrigerator/Freezer Guard will answer. How do you enter a negative number when programming a temperature limit. To enter a negative limits, press the * key and then enter the number. For example, to enter -15 degrees, press the *15 and then the pound. You will here “negative 15 degrees”.
