form the following test. 
1  Use another phone line and call the Temperature Guard. 

2  When asked to enter the pin number, enter “

#999“

 (including the “pound” sign). 

Hang up 

after the Temperature Guard says “

Goodbye

” 

The Temperature Guard will call all of the programmed telephone numbers. 
Do not enter the PIN during this process or the unit will stop calling out.   

Troubleshooting Tip #1

 

You can listen in to verify communication by waiting 10 seconds after hearing “Goodbye” 
and listening in on a phone on the same line. 

 

What do I do if the Temperature Guard doesn’t call my phone numbers? 

Verify that the numbers are programmed correctly.  Telephone numbers must be pro-
grammed exactly as they would be dialed from a telephone on the same line. (Including 1 + 
area code, if necessary) 

Verify that a DSL filter is in place if there is DSL service on your telephone line. 

Verify that you have “touch tone” service. 

Verify that you have long distance service if calling a long distance number. 

See Troubleshooting Tip #1 above, listen for messages from the phone company during 
the test call. 

If you have a digital phone line through your cable company or other non-standard tele-
phone system (Vonage, VoIP), our system may not be compatible with it.   Your telephone 
service provider may be able to assist you by adjusting their hardware.  There are no set-
tings on the Temperature Guard to adjust. 

 

Some Helpful TIPS 

• 

If the Temperature Guard is having trouble receiving your programming entries, try 
holding the button for a longer amount of time. 

• 

Include all necessary digits for phone numbers.  Long distance numbers must include 1 
and the area code.  Do not turn off your long distance service if you are going away for 
an extended period of time and you expect the Temperature Guard to call a long dis-
tance number.   

• 

Do not place the unit in direct sunlight as this will effect the temperature and humidity 
readings. 

• 

Do not place the unit near heating or cooling sources if you wish to monitor the average 
temperature of a room.  

• 

Placing the unit on the floor will cause the Temperature Guard to sense a temperature 
that is lower then the actual ambient temperature. 

• 

To monitor the power status of specific devices; connect the Temperature Guard’s 
power plug into the same power source as the device you wish to Temperature Guard.  
It is possible for an isolated power outlet to lose power.
