Your MXD unit is equipped a highly sophisticated radio receiver that is carefully matched to the PHB.
The receiver has very high sensitivity, and interference rejection. The PHB is waterproof and designed
specifically for PERS service.
The base unit can receive signals from the PHB from a distance of up
to 600 feet.
*
* Your MXD unit is designed to provide for your peace of mind and comfort within the privacy of your
home and yard. The signal from the PHB is limited by various factors, and may vary from home to home.
It is your responsibility to know the effective operating limits of your PHB, and to use it within these
limits. See page 7, step 5 for instructions on how to complete a PHB range test.
Battery Monitoring
Your MXD unit is equipped with an internal rechargeable battery; the battery provides uninterrupted
power to your MXD unit for up to 80
hours if AC power is lost. While the battery powers your MXD
unit, the battery condition is constantly monitored by the MXD unit.
ETL Listed
The Mytrex MXD has been certified by ETL to UL Standards 1637 and 1635, and Canadian CSA
standards for Home Health Care Signaling Equipment. The ETL Listed Mark is proof that your MXD unit
has passed rigorous product safety testing, and has achieved certification.
Remote Programming
Any operational function or parameter can be reprogrammed to customize your MXD unit to your
specific needs, such as dialing “9” to obtain an outside line from your telephone system.
Optional Features
Automatic Voice Test
Subscribers may request the MXD to initiate periodic Automatic Voice Test from their service provider.
Many subscribers feel that these tests provide them with added safety and peace of mind. During an
Automatic Voice Test all critical functions of your MXD unit are tested, including the microphone,
speaker and PHB, to ensure the system is working properly. When the Automatic Voice Test feature is
enabled, the MXD will automatically send an “Automatic Voice Test” message to your response center.
The attendant will greet you, and may ask you to press your PHB, verify your address and phone number,
and ask if any assistance is needed.
Automatic Dial Test
If the Automatic Voice Test is not used, it is strongly recommended that the Automatic Dial Test feature
of your MXD unit be used. This test verifies the ability of your MXD unit to deliver a message to your
response center. When the Automatic Dial Test feature is enabled, your MXD unit will automatically
send an “Automatic Dial Test” message to your response center. If the response center does not receive
an expected test call from your MXD unit, the response center or your service provider may contact you
to help determine the cause.
AC Power Monitoring
Your MXD unit can detect AC Power loss and AC restore, and may be programmed to send automatic
“AC Fail” and/or “AC Restore” messages to the response center.
