PoWer suPPly
The MURS Alert probe transmitter is powered by 4 CR123 batteries. It is recommended
that you use good quality batteries. When changing the batteries, do not mix old and
new batteries together. The life of the batteries should be about 6 months under normal
conditions. In high trac areas, the batteries will go down sooner. Also, in a cold climate
it is recommended that you put fresh batteries in at the beginning of winter.

Function
A. Detection: The MURS Alert probe transmitter is a metal detector that can be used to
detect vehicles. The probe sensor will detect movement of vehicles about 14 feet either
side of the probe. When a vehicle is detected, the MURS Alert will transmit a signal.
B. In order for the sensor to detect properly it is recommended that the probe be buried
along side the drive and the transmitter box mounted 4 to 5 feet high on a tree or post
nearby. If you have a very wide driveway, you may need to bury the probe in the center
of the drive. If you do this, place the probe and wire in a 2 inch schedule 80 PVC pipe and
bury it at least a foot deep. This is done to protect the probe and wire from any damage.
It is also prudent to place the wire in a conduit to protect it from inadvertent damage
from rodents or future digging projects.
C. Alert Signal: When a target is detected by the MURS Alert, an alert signal will be sent
to the M538-HT or M538-BS MURS transceiver. There are 4 dierent alert signals that
can be sent. The alert signal will be “Alert Zone One,...”, “Alert Zone Two,...”, “Alert Zone
Three,...”, or “Alert Zone Four,...”.
