LTE, contact your service provider as soon as possible.
Notice to End User: Wireless Telephone Reliability Considerations When
Using the MXD-LTE Personal Emergency Response System
Your MXD-LTE has been designed to be very reliable when sending an alarm signal to the monitoring
center and then connecting the call to a live attendant. However, the MXD-LTE must have sufficient cell
phone reception to make and maintain a call using a cellular network.
Because wireless phones communicate using radio waves, you are hereby advised that the ability of the
MXD-LTE to connect to your monitoring center via the wireless telephone network is influenced by
many factors, including:
•
The distance between the MXD-LTE unit and the cell tower with which it is communicating. Please
understand that even though you may get reliable cell service using your personal cell phone from
your home, there is no guarantee that the MXD-LTE will do the same, as your personal cell phone
may use a different network and/or lack LTE technology.
•
Transmission of the cell signal may also be hindered by physical obstacles between your MXD-LTE
base unit and the nearest compatible base station, such as hills or large buildings; the presence of
unwanted electronic signals introduced by circuit components in microwaves, computers and
other electrical devices; or natural disturbances created by severe weather or even cloud
coverage.
•
Cell signal connection quality to and from the local cellular networks can and does vary,
sometimes substantially, from minute to minute. Moving the MXD-LTE base unit even just a few
feet can affect cell signal connection quality. It is possible that your unit will not be able to
complete a call because of the lack of cell service even though a connection was made without
problems when the unit was first installed and tested.
•
A large number of cell phone users trying to use the local network at the same time may overload
cell circuits and cause your MXD-LTE to detect a “busy” signal instead of completing its call.
•
During a local disaster, personnel from local, state, and federal emergency agencies may be given
priority to use the cell system. If this happens, your alarm call may not go through.
•
While wireless service providers attempt to design their networks to eliminate dropped calls, busy
signals and dead zones, no network is perfect, and coverage breaks within the general coverage
areas are still possible.
•
Calls may take a little longer to be connected to the Response Center than landline calls – perhaps
as much as two minutes from the time you press your personal help button – due to switching
and other delays.
•
Your MXD-LTE has an internal backup battery that will allow it to continue to operate for up to 27
hours after the loss of AC power. When the unit is powered by the battery, it may take a few
seconds to “wake up” and send a signal to the cell network, because the cell phone circuit may be
turned off to save energy. If your AC power is off, please be patient while the MXD-LTE unit turns
on its cell phone circuit and makes the connection to the network.
Please note:
the MXD-LTE’s
battery can only re-charge while the power switch is in the on (“I”) position.
