Don’t wait to replace the battery until
you get the low memory battery warn-
ing. Depending on how often you use
the PLGR, that warning might come and
go without your seeing it. If the battery
is a year old, this
is
your warning!
Also, be aware that a dead memory
battery might leak. If it does, it could
damage the battery compartment and
other areas of the PLGR.
Some leaks happen when you screw
the memory battery cover back on. The
cover’s coiled spring punctures the bat-
tery. Make sure the spring has not been
twisted out of alignment. If it has, get it
back in place before you put the cover
back on.
When you replace the 3.6-volt, lithi-
um battery don’t be fooled into using an
AA battery. The 1.5-volt, L91, lithium
battery, NSN 6135-01-333-6101, likes
to impersonate the memory battery. It
will fit into the compartment, but it lacks
the power to hold on to the stored data.
When you’re changing the memory
battery, don’t forget to have a pri-
mary battery installed or to connect
your PLGR to an external power
source. Otherwise, you’ll wonder
where your memory went.
Finally, when you send your PLGR in for repair, send the memory battery with
it—installed in the PLGR! To diagnose and repair the PLGR, the manufacturer will
need to see the info the memory battery has stored.

Global Positioning System…
Thanks for the Memories
The battery is
good for a year,
but after that, it’s
on
borrowed
time…
…And
so is my
memory!
fault
codes…
satellite
data…
my
almanac!
so
where
is it!?!
say, chum,
did you
remember
to change
the PLGR’s
battery?
I’m s’posed
to change the
battery!?
ah… I
forget?
O
nce a year, cowboy, you need to
say adios to the 3.6-volt, lithium
memory battery, NSN 6135-01-
301-8776, in your precision light-
weight GPS receiver (PLGR).
The memory battery preserves
the fault codes, satellite data and
almanac when your PLGR is not in
use. But like any battery, this one
will eventually run out of juice.
Your PLGR’s
memory battery
doesn’t look
like much, but
if it’s dead,
leaking, or
missing, you can
say
goodbye
to your stored
data.
what? 1.5
volts?
no sir,
I’m 3.6 volts
all the way!
you’re s’posed
to have all
that stuff!
