Testing the PHB (Range Test)
1. Locate the T/L button on the back of the MXD and press one time (Figure
1).
2. The MXD 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 MXD, 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 MXD and/
or contact your service 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 MXD (Figure 1). The unit
will announce the "System Ready."
Note: The manufacturer recommends that the
MXD be tested at least every 30 days. Emergency
Response Center Operators are available 24 hours a
day to help.
1. Push the button on your activator and wait for
the Emergency Response Center Operator to
speak to you through the MXD.
2. When the Emergency Response Center
Operator answers, simply inform him/her that
you are doing a test.
