2-1: PRECAUTTONS
1. ElKl "N" seriqs projectors have been designed
for the ultirnate in simplicity and ease of seryice
and repair. Eaeh screw is very impcrtant, and
when servicing or re-assembling th€ projector,
scfaw$ should not b€ omittd
or carelessly fost.
All screws should be firmly tightened to assure
rel iable projector operation after re-assembly -
?. When lubricating the projector's plastie parts,
silicon oil or grease should be us€d. Other types
of lubricants may harm plastic partr. Avoid
using any solvents such as Trichloroethylene,
which will harm rnost plastic or painted parts.
3. EIKI projectcrs require a minimum of special
tsols. The mort important is an ordinary l5O
Phillips screw driver s€t.
4. To avoid damage to screw heads, it is important
to remember the adage "70% push, 3096 turn."
It is also irnportant to select the right size screw
driver blade. A rule of thurnb is to use the largest
blade possible.
5. To avaid possible electrical shock, always dis-
connect the proiector from the power source
when servicing.

AND TEST EQUIPM€NT
A. Tools:
When servicing ElKt "N" series, ordinary
ISO {Phillips type} screw drivers and single-
bladed scr'evr drivers should be enough.
(ElKl screw driver kits, PlN 5615 are availa-
ble-) A Malex extractor taol is most useful
when replacing the pins of Nylon connectors
to the transformer or motcr,
B. Speciallcols:
ElKl "N" series have been designed so that
no special tools are required to service the
projector. However, a common elaw protru-
sion gauge {Tool No- 32O{1T} is most
helpful for accurately setting the claw pro-
trusion. Standard 16mm film may be used as
a thickness gauge where n€cessary- {Most
filrn is about 0.l5mm or -005" thick).

C. T s! _quipment:
A limited amount of test equipment is required
for routine maintenance and modular replace-
ment. However, vrhen servicing the individual
modules such as the amplifier, the follawing
equipment and test films would be essential:
a. Vom {Voltage/Ohm meter}
b. Oscilloscope
c. Audio AC VTVM
d. Wow & Flutter Meter
e.40slHz SMPTE Test Filrn
f. 3130t1z Wow & Flutter SMPTE Test

g. Mulli Frequency SMPTE Test Film
h. 7000H2 Sound Focus SMPTE Test Filrn
i. 7000H2 Mag. Azimuth SMPTE Test Film
i- Buzz Track SMPTE Test Film.
