1. SafetyPrecautions
1.1. General Guidelines
-Forcontinuedsafety, no modification ofanycircuitmust be
attempted.
-Unplug thepowercordfromthepoweroutlet beforedisassembling
thisprojector.
-Itisadvisabletouse anisolation transformerintheACpowerline
beforetheservice.
-Observetheoriginal leaddress during theservice. Ifashortcircuit
isfound, replace all theparts overheatedordamagedbytheshort
circuit.
-Aftertheservice, all theprotectivedevices suchas insulation
barriers, insulation papers, shields, and isolation R-C
combinationsmust beproperlyinstalled.
-Aftertheservice, check theleakagecurrenttopreventthe
customerfromgetting anelectricshock.

3. Connect M1toT1according toFig. 2and measurethevoltage.
4. Changetheconnection ofM1fromT1toT2and measurethe
voltageagain.
5. Thevoltmetermust read0.375 Vorlowerinbothofsteps3and 4.
Thismeansthat thecurrentmust be0.75 mAorless.
6. Ifthereading isoutoftheabovestandard, theprojectormust be
repairedand recheckedbeforereturning tothecustomerbecause
ofapossibilityofanelectricshock.
1.3. UVPrecaution and UHMLampPrecautions
-Besuretounplug thepowercordfromthepoweroutlet when
replacing thelamp.
-Because thelampreaches averyhigh temperatureduring its
operation, waituntil itcoolscompletelywhenreplacing theLamp
Unit.

-Thelampemits small amounts ofUV-radiation, avoiddirect-eye
contact withthelight.
-Because thehigh pressurelampinvolves arisk ofexplosion, never
touchthelampwireleadduring theservice. (See Fig. 3)

Whencontrolling multipleprojectorssimultaneouslywithasingleremotecontrol unit, remote
control unitIDissetintotheprojector IDor into"ALL" as describedinthestepsbelow:
1. PushIDSETbutton on theremote control unit.
IDnumber"ALL"will bedisplayedon theOSD.
2. Press theIDSETbutton 2secondsorlonger.
TheIDnumberwill changeinto"1". TheIDSETbutton will now
togglethrough IDnumbers"2", "3", "ALL", "1", and soon each
timeitissubsequentlypushed.
3. Select theIDnumberyou wish, thenpushENTERbutton on the
remote control unit.
Note:
Since theremote control unitIDisset to"ALL"byinitial setting, it
isnotrequiredtoset anIDnumberwhentheinitial setting isnot
changed.
