code. These groups are accessed by placing the MXD base unit into RANGE TEST MODE by following
steps 1 through 3 for programming medication dispensers, and then by pressing the T/L button again to
enter in sequence each of the eight smoke detector, eight supervisory PHB, and eight CO detector groups.
Please note that no devices are currently available that are set up to communicate with the MXD
equipment, and the groups for these detectors should skipped for the present time when programming the
MXD to recognize PHBs and medication dispensers. Press the RESET button one time to exit the device
programming mode. When the RESET button is pressed, the unit will return to normal mode and
announce,
“
System Ready.

Mytrex MXD Features
Microphone and Speaker
The microphone in your MXD unit is sensitive enough to hear voice communication around corners and
in other rooms of your home. You do not need to be in the same room with the MXD unit for the response
center to hear you! Your MXD unit’s audio system is engineered to provide for an increase of up to 83
times the normal volume.
Two-Way Voice Communication
After connecting to the response center, your MXD unit shifts to a voice communication mode. When in
this mode, the response center attendant switches the MXD base unit between “talk” and “listen” modes.
This greatly increases the coverage and range of clear communication between you and the response
center attendant.
Remote Answering Feature
Your MXD may be used to answer an incoming telephone call. If your phone is ringing and you want to
use this feature, simply push the PHB and the MXD will become active in two-way voice communication
mode. To end the call, simply push the PHB again.
Hint:
Push the button while the phone is actually
ringing to make sure the calling party is waiting for you to answer the call.
Note:
In order to ensure that
the phone line is cleared in case you forget to end the call, the MXD will only remain connected for a pre-
set number of minutes, after which the MXD will automatically disconnect the call even if you are still
having a conversation. In the event that you need to send an alarm to your monitoring center while in
remote answer mode, push the PHB to disconnect the call, wait about 10 seconds, and then push your
PHB again to initiate the alarm call.
Inbound calling to the MXD
Your monitoring center and individuals authorized by you may activate your MXD to answer their
inbound calls without your doing anything. To use this feature, the calling party must first be provided
with a four digit code. A calling party with a valid code first calls your telephone number and lets it ring
once, and then disconnects the call. Then the individual waits 20 seconds and calls again. The MXD will
answer the second call after the third ring and send a beep signal. The caller then enters their code and
the MXD will shift to two-way voice mode if the code is valid.
Waterproof PHB
Your PHB may be worn as a necklace, or a bracelet. Both styles are waterproof, and should be worn in
the bathtub and/or shower. Your PHB uses an indicator light to show the status of its internal battery.
While your PHB is being pushed, the light on your PHB flashes green to indicate the internal batteries are
good; a red light indicates the internal batteries may be weak. Every time the response center receives a
signal from your PHB, its battery status is reported. Soft Touch PHBs, which require about half the
pressure to activate, are available. For more information contact your service provider.
