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.

-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)

6.2. CautionsforAdjustment
-Neverturnoff theMAINPOWERswitchuntil everyfancompletely
stops.
-To maintainand ensuresafety, alwaysuse thedesignated
components forreplacementparts.
-Ifremoving anyclamps, leadwires orconnectors, alwaysplace
themback intheirproperlocations.
-Becareful nottodamagetheleadwires orcomponents whenusing
asoldering iron orsimilartool.
6.3. Setting BeforeAdjustment
-Set up theprojectortoobtaintheprojection distance below.
-Turnthezoomknob ofthelensblock toobtainthelargest sizeof
