Testing the PHB (Range Test Mode)
1. Locate T/L button on the back of the MXD3G and press one time.
2. The MXD3G will announce “Range Test Mode.”
3. Immediately activate the PHB by pressing and holding down the button. A green light will illuminate
on the PHB and a steady tone will sound from the MXD3G as long as it is detecting the PHB.
4. While activating the PHB, walk around all areas of the home and yard. Listen for gaps in the tone.
Gaps indicate “dead zones” where the PHB is not detected. If “dead zones” are detected, try
relocating the MXD3G and/or contact your provider.
5. To finish the Range Test, stop pressing the PHB. After the tone stops, press the black RESET button
on the back of the MXD3G. The unit will announce the signal strength and “System Ready”.
Testing the MXD3G
The manufacturer recommends that the MXD3G be tested at least every 30 days. Most response
centers welcome regular testing. Attendants are available 24 hours a day to help. Please check with
your provider concerning their testing policy.
1. Press the PHB and wait for the response center attendant to speak to you through the MXD3G.
2. When the attendant answers, simply inform him/her that you are doing a test.
Troubleshooting (Status Light)
The MXD3G speaks the system status each time the RESET button is
pressed. The Status light displays the following light signals when
operating.
Unit is properly connected
Unit is currently trying to call the response center
AC power not available, unit is running on battery
Cellular connection problem or weak signal strength
Cellular connection problem and AC power problem
When the MXD3G is in “Range Test” mode, the Status light will show:
Base unit is receiving signal from the PHB
Base unit is NOT receiving signal from PHB
Turning off the MXD3G
The MXD3G automatically turns on when it is connected to AC power.
When the MXD3G is removed from service, it is important to turn it off to
preserve the battery.
1. Unplug the MXD3G from the AC outlet.
2. After the Status light begins to flash, press the T/L button on the back
of the MXD3G three times.
3. The base unit will speak “Hold help to turn off.”
4. Press and hold the HELP button until the Status light stops blinking.
