I
f your unit has received an
expendable-unattended
ground
sensors (E-UGS) system, read
this article carefully.
This applies
to all E-UGS conFgurations.
The E-UGS comes with 55
ground
sensors.
Each
sensor
contains
one
non-rechargeable
battery pack. When you receive
a sensor, you won’t know how
much battery life is left. That
means
you
might
position
a
ground sensor that has a short
battery life. Or you might think a
powerless sensor is faulty. Either
way, your surveillance suffers.

The E-UGS consists of one base station kit and one sensor kit.
±or more E-UGS information and technical support, go to the Applied Research
Associates (ARA), Inc. website:

How Much Battery Life?
Before you position a ground sensor, Fnd out how much life is left in the battery
by running a system function test:
Press the mode button on the bottom of the sensor for
1 second:
•
If the battery indicator light blinks
green four times,
it means the battery is
fully charged.
•
If the light blinks
green three times and red once,
the battery has a
75 percent charge.
•
Two green
and
two red blinks
mean a
50 percent
charge.
•
One green
and
three red blinks
mean a
25 percent
charge.
Run the test on each sensor when your unit receives
the E-UGS and again right before deploying the sensors.
The system function test is described in the user’s manual,
which comes with the E-UGS.
A fully charged battery can last 3 to 4 months. It’s recommended you replace the
sensor if it shows a 50 percent charge or less.

Don’t bother
to recover

in the field.
instead,
position
new
sensors.
That’s the
recommendation
from PM Ground
Sensors.
Check battery charge
before
use
well, I’m getting ready
to put you guys out to
do your thing… I just
need to ask you first…
are your
batteries
good?
y
eah
h
h
!
suuure
they
are!
soldier, you need to
check us sensors
-- each
and every one --
before
you put us to work.
oh, c’mon guys
this is
important!
