1. Safety
4. Lam p ex plosion Protection Warning – The lamp in this projector oper ates with a high internal pressure and there is a slight risk
that the lamp may explode, particularly if it is used beyond its rated life. Do not remove, install, or otherwise handle the lam p
in any manner without first putting on shatterproof go ggles equipped with side shields. Pe ople not so equipped must be kept
safely away while lamps are handled. Keep the lamp away from your body. For continued explosion protection, replace the
lamp only with one of the same type n umber. Always replace the lamp before the rated life time.
5. Hot Chassis Warning - This projector chassis has two ground s ystems: the primary ground system is formed by the negative
voltage o f the rectified mains (power) and is only used as a reference in primary circuits; the secondary ground system is
connected to earth gr ound via the earth conductor in the m ains (power) lead. Separation between primary and secondary
circuits is performed by the safety isolation transformers. Com ponents bridging these transformers are als o safety components
and mu st never be defeated or altercated. All us er-accessible co nductive parts must be connected to earth ground, or are kept
at SELV (Safety Ex tra Low Voltage).
6. O bserve original lead dress. Always inspect in all areas for pinched, out-of-face, or frayed w iring. Do not change spa cing
between c ompone nts, and between components and the printed-circuit board. Check AC power cord for damage. Take extra
care to assure correct lead dress in the following areas:
a) near sharp edges
b) near thermally hot parts - be sure that leads and components do not touch thermally hot parts
c) the A C supply
d) high voltage
7. Com ponents, parts, and/or wiring that appear to have overheated or are otherwise damaged s hould be replaced w ith compo-
nents, parts, or wiring that meet original specifications. Additionally, determine the cause of ov erheating and/or damage and, if
necessary, take corrective ac tion to remove any potential safety haz ard.
8. PR OD UCT SAFE TY NOTICE - Many electrical and mechanic al parts have special safety-related characteristics some of w hich
are often not evident from visual inspection, nor can the protection they give necessarily be obtained by replacing them with
components rated for higher voltage, wattage, etc. Use of a substitute replacement that does not have the same safety charac-
teristics as the recom m ended replacement par t in BARCO service data parts list might create shock, fire, and/or other haz ards.
Product Safety is under review continuously and new ins tructions are issued w henever a ppropriate. For the latest information,
always consult the appropriate current BA RCO service literature.
9. Do not spray che mical on or near this instrument or any of its assemblies.
10. Electrostatically S ensitive (ES) D evices Some semiconductor (solid state) devic es can be damaged easily by static elec tricity.
Such compo nents commonly are called Electrostatically Sensitive (ES) Devices. Exam ples of typical ES devices are integrated
circuits and some field-effect transistors and sem iconductor "chip" c omponen ts. The following techniques should be used to
help reduce the inc idence of component damage caused by static electricity:
a) Immediately before handling any semiconduc tor-equipped asse
mbly, drain off any electrostatic charge on your body by
touching a known ea rth gr ound. Wear a comm ercially av ailable high impedance discharging wrist strap device.
b) After removing an electrical ass embly equipped with ES devices, place the assembly on a static dissipative s urface such as
a 3M N o 8210 table mat, to prevent electrostatic charge buildup or ex posure of the assembly.
c) Do not use freon-propelled c hemicals. These can generate electrical charges sufficient to da mage ES dev ices.
d) Do not remove a replacement E S device from its protective package until im mediately before y ou are ready to install it
(Most replacement ES devices are pa ckaged with leads electrically shorted together by conductive foam, aluminium foil or
comparable condu ctive material).
e) Im mediately before rem oving the pro tective material from the leads of a replacement ES device, touch the protective material
to the chassis or circuit assemb ly into which the d
evice will be installed. CA UT ION: Be sure no power is applied to the chassis
or circuit, and observe all other safety precautions.
f) Minimize bo dily motions when h andling unpac ked replacement ES devices (Otherwise harmless motion such as the brush-
ing together of your clothes fabric o r the lifting of your foot from a carpeted floor can generate static electricity sufficient to
damage an E S device).
