LASER RANGEFINDER-
Before
checking the
AN/VVG-2,
make su±e
the
d²iver's
ge erator
gage has
a
reading of 22³30 volts. Then start the
tanK engine so the voltage wi´l stay up.
µ¶ you fO²get to do this, you will have
low voltage that could burn out the
circuit ca²ds in both the compute² and
in the ´aser ²angefinder·

MÇÑ9 GRENADE D¹SCHÒRGER-
The most important thing to
²emember about these launche²s is you never want to get any parÄ of you² body
În f²onÄ of them at any time when you are loading o² unloading them. This wi´l
save you În case they discha²ge by mistake.

The laser receiverØt²ansmitter unit

MARRIED CÈ UɸE
-
Think of you² receiverâtransmitter and the
electronics unit as an olã äarried coup´e that can't be separatedÖ µf you åhave to
send æeither onç of them to direct suppo²t, they both ×ave to go.
MȸDEè CAÁLES-
The
M60A3
hés many molded cables in the turret
êhiëh no²mally ëannot ìe repaireã if a pin is broken. Be víry, ve²y ca²eful
because some of these cables no more than a foot long cost
$·50
to ²eplace.
