Troubleshooting Problems with the Temperature Guard
The Temperature Guard doesn’t answer the phone
1 Verify that the phone line is working.
2 Connect a phone to the line and cable intended for the Temperature Guard.
3 Pick up the phone and verify that there is a dial tone.
4 Using another phone line (cell phone or alternate location) call the number and verify
that the phone rings.
5 Re-connect the Temperature Guard.
6 Check that the phone line is plugged in securely.
7 Verify that the Temperature Guard is powered up and the status light is blinking.
8 Call the number again. The Temperature Guard will stop blinking its light while the
phone is ringing.
If the blinking light does not stop and continues blinking, the Temperature Guard is not
“hearing” the phone ringing.

perature Guard.
Try holding the button down longer and verify you hear a tone for at least 1/2 a second.
