PHB or the Base Unit Help Button if the unit is properly installed. The unit will sound two quick tones
when it is reset. If voice announcements are enabled the unit will announce, “System Ready.”
The RESET Button may also be used to cancel your call for help if your MXD unit is inadvertently
activated. However, to cancel a call for help the RESET Button must be pressed within 10-15 seconds of
activation; otherwise, the unit will already be communicating with the response center. The response
center is staffed 24 hours a day, therefore, it is best to allow your MXD unit to complete the call and tell
the attendant that you accidentally activated your MXD unit.
Personal Help Button (Figure 3)
Each MXD unit is supplied with one or more Personal Help Buttons (PHBs). The PHB is a small
waterproof pendant that may be worn around the neck on a breakaway cord, or may be worn attached to a
wrist band. When pressed, the PHB sends a “Help needed” radio signal to the MXD base unit, causing it
to call the monitoring center. Within a few seconds, an attendant will talk to you through your MXD base
unit’s speaker to determine if help is needed. The PHB transmitter and the base unit receiver are carefully
designed to ensure that the base unit can detect the PHB’s signal at distances of up to 600 feet away from
the base unit.
Setup Guide
Your MXD is designed to work with many different types of telephone technologies, including traditional
Plain Old Telephone Service (POTS), Voice over Internet Protocol (VoIP), cable company telephone
systems, and Digital Subscriber Line (DSL) service. This section provides instructions for setting up the
MXD to work with POTS, DSL, and VoIP telephone service. Telephone systems provided by cable
companies generally require connections similar to POTS telephones. Please contact your service
provider if none of the following setups work for your system.
Initial Setup steps for Any Type of System:
For any of the following setups:
1. Locate a live telephone jack with an electrical outlet nearby. The electrical outlet must
not be controlled by a light switch. Select a location where the MXD unit can be placed
on a flat, horizontal surface and where it will be located centrally, in a part of your home
that is used frequently. While it is recommended that the MXD be placed on a flat,
horizontal surface, it can be wall mounted if necessary. The MXD unit should be located
away from the immediate vicinity of mechanical noise sources, i.e. oxygen generators,
electrical equipment, and all appliances such as televisions or stereos.
2. If a telephone handset has not been plugged into the telephone jack and used recently,
plug a telephone handset into the jack and make a call using the handset to a working
telephone number. Confirm that the call goes through and that both parties can hear and
speak to one another.
3. Unplug the telephone handset cord from the wall jack.
