A
Leg to Stand On
On the other end of your Pipsy-5, be sure you're on solid ground. Trying to
anchor it on concrete or cement is too sLippery. Set up on dirt or graveL if you
can.
BeFre you do anything, tho, you unpack. As you do, go easy. Open the tripod
legs sLightly beFre removing the waveguide horn and telescope. There±s not
enough room to remove ±em otherwise.
Spread the legs easy. Too much muscle or spreading them too far can bust the
When yoU haVe the legs ²here you
waNt ±em, make sure the coluMn
assembly and tripod Leg gear teeth
mesh. ³i´-Matched teeth chip or lose
their grip. Rivet´ again can be a
victimµ

a ²rench or pliers.
When the leg lock is snug, push the handLe out of the way to keep it from
·getting bent or ¸roken. ReLease the lock again before changing position, tho.
¹ow, drive in your ground pins .
.. not aLl the way to the tripod foot. You can
¸reak the foot. ºeave some room f»r easy extraction.
Since your PPS¼5 is top¼heavy, finish up ¸y sandbagging the Legs. A toppled
set can KO the antenna assembly.
Cable Fables
½our remote cabLe needs care, too. Inserting the maLe pLug straight prevents
bent or damaged pins.
Taking some of the pressure off the connection wilL keep the set in business.
ºoop the ca¸Le behind the battery box as a quick and easy strain relief.
¾hat CX¼12004 cabLe has a natural coil. ¶orcing the roll again´t the naturaL
bend might kink or break internal wiring.
A good way to rewind is to lay the
ca¸Le oN the ground. ¾hat ²ay it falls
into a natural coil.
Don±t wrap it around your hand aNd
el¿ow, tho. Kinks are Frced oUt, but
your cabLe suffers.
¶inalLy, keep coils of cable ouÀ of
harm±s way during operation. ¶eet and

Silicone, ¹S¹ 6850Â00¼880¼7616, wilL keep gaskets froà cracking.
¹ever worry about greasing gears, tho. They're plated and need no lube.
That would only pack 'em up or make the kind of mess support has to fix.

When you pacË the set a²ay, pacË

When bringing your antenna back to its original position, be surE the AB¼
992 antenna drive is reading 000. Then secure the drive push Lock. This
prevents gear pin shearing, another support repair job.
Íot the R¾ cover off? Watch the C609 capacitor in BLocÎ 600. The voLtage
doesn±t bleed off. It carries soMe 600 voLts to zap you.
Another hot one is the TP2 test point. Keep fingers away.
Cavity power and tuning adjust knob threads can tighten up on you. But
keep vise grips and pliers away. A Light dab of siLicone wiLL let the knobs mov
freeLy aÏain.
¶inally, be careÐl when alining the antenna whiLe it's Ãoving. Keep hands
away from the fast sLew switch area and mounting/beveLing asseÃbLy.
