NOTE TO SERVICE PERSONNEL
UV-RADIATION PRECAUTION
The light source, metal halide lamp, in the LCD
projector emits small amounts of UV-Radiation.
A VOID DIRECT EYE AND SKIN EXPOSURE.
To ensure safety please adhere to the following:
1. Be sure to wear sun-glasses when servicing the
projector with the lamp
turned “on” and the top
enclosure removed.
2. Do not operate the lamp outside of the lamp housing.
3. Do not operate for more than 2 hours with the
enclosure removed.
UV-Radiation and Medium Pressure
Lamp Precautions
1. Be sure to disconnect the AC plug when replacing
the lamp.
2. Allow one hour for the unit to cool down before
servicing.
3. Replace only with same type lamp. Type
CLMPF0053DE03 rated 65V/155W.
4. The lamp emits small amounts of UV-Radiation,
avoid direct-eye contact.
5. The medium pressure lamp involves a risk of
explosion. Be sure to follow installation instructions
described below and handle the lamp with care.
Lamp Replacement
Note:
Since the lamp reaches a very high temperature
during units operation replacement of the lamp should
be done at least one hour after the power has been
turned off. (to allow the lamp to cool off.)
Installing the new lamp, make sure not to touch the
lamp (bulb) replace the lamp by holding its reflector
2.
[Use original replacement only.]

DANGER ! –– Never turn the power on without
the lamp to avoid electric-shock or damage of the
devices since the stabilizer generates high voltages
at its start.

Cleaning the lenses and reflectors
1. Lens cleaner
• Cleaning liquid:
Change the mixture ratio of alcohol and ether depending on ambient
temperatures. Make sure that the liquid evaporates from the lens
surface immediately after you rub it: This is the best ratio. The more
ether is used, the quicker the liquid evaporates.
• Method:
Use well-washed bleached cotton cloth or cleaning paper available
on the market. Damp the bleached cotton cloth with the liquid, and
hold the lens sandwiched in the cloth with your thumb and the index
finger. Turn the lens and wipe the surface clean from the center
outward to collect dust. Be careful not to rub the coated surface too
strong.

Controlling the total operating hours of the lamp
The following control is carried out when the lamp has been used for 1,900 hours and 2,000 hours.
1. After 1900-hour use
When the power is turned on, "LAMP" appears in the on-screen display for about 1 minute (flashing in yellow)
and the lamp LED indicator lights up in red.
When the 1,900-hour point comes up during use of the unit, the "LAMP" display starts flashing in yellow on the
screen for 1 minute at the very 1,900-hour point.
Now the lamp LED indicator changes from green to red.
2. After 2000-hour use
When the power is turned on, "LAMP" appears in the on-screen display for 5 minutes (flashing in red) and the
lamp LED indicator lights up in red. Five minutes thereafter, the power turns itself of f and the unit is interrupted.
When the 2,000-hour point comes up during use of the unit, the "LAMP" display starts flashing in red on the
screen for 5 minutes at the very 2,000-hour point. Five minutes later, the power turns itself off and the unit is
interrupted. (The lamp LED indicator stays red since the 1,900-hour point.)
If you try to turn on the power twice after the 2,000-hour point, the unit remains off.
3. When the 2,000-hour point comes up, take the following steps.
Replace the lamp with new one. While holding down both the "VOLUME "" and "SELECT/ADJ "" Keys on the
unit, turn on the main power switch (located on the back of the unit). The lamp operating hourmeter is now reset
to zero. Turn on the unit and make sure the time display shows "0000H".
XV-C100A/M/E
4. Displaying the total operating hours of the lamp
Change the STATUS3 data settings: PICTURE at 0, BRIGHT at MAX, COLOR at MIN, TINT at MIN, and
SHARPNESS at MAX. Hold down the SOUND DOWN and ENTER keys for longer than 2 seconds. By doing
this, the total operating hours will be displayed on the screen.

HINWEIS FÜR DAS WARTUNGSPERSONAL
ACHTUNG: UV-STRAHLUNG
XV-C100A/M/E
Die Lichtquelle im LCD-Projektor, eine MetallHalogen-Lampe, gibt eine geringe UV-Strahlung ab.
DIREKTE BESTRAHLUNG AUF AUGEN
UND HAUT MUSS VERMIEDEN WERDEN.
Zur Gewährleistung der Sicherheit muß folgendes
beachtet werden:
1. Bei Arbeiten am Projektor bei eingeschalteter
Lampe und abgenommenem oberen Gehäuse
muß unbedingt eine Sonnenbrille getragen
werden.
2. Die Lampe darf nicht außerhalb des
Lampengehäuses eingeschaltet werden.
3. Betrieb für länger als 2 Stunden bei
abgenommenem Gehäuse ist nicht zulässig.
Zur Beachtung bei UV-Strahlung
und Mitteldruck-Lampen
1. Vor dem Auswechseln der Lampe muß der
Netzstecker gezogen werden.
2. Vor Durchführung von Wartungsarbeiten muß das
Gerät eine Stunde abkühlen.
3. Die Lampe darf nur gegen eine der gleichen Art
ausgewechselt werden. Typ CLMPF0053DE03,
bemessen für 65V/155W.
4. Die Lampe gibt eine geringe UV-Strahlung ab,
daher muß direkter Augenkontakt vermieden
werden.
5. Die Mitteldruck-Lampe weist ein Explosionsrisiko
auf. Daher müssen die nachstehenden
Installationsanweisungen beachtet werden, und
die Lampe muß vorsichtig behandelt werden.
ËAuswechseln der Lampe
Hinweis:
Da die Lampe während des Betriebs sehr heiß wird,
sollte die Lampe erst ausgewechselt werden, nachdem
das Gerät mindestens eine Stunde ausgeschaltet war,
damit die Lampe ausreichend abkühlen kann.
Beim Installieren der neuen Lampe muß darauf
geachtet werden, die Lampe selbst (Glaskolben)
nicht zu berühren. Vielmehr muß die Lampe am
Reflektor 2 gehalten werden.
[Es darf nur ein Original-Ersatzteil verwendet
werden.]

GEFAHR! — Niemals die Spannungsversorgung
einschalten, ohne daß eine Lampe vorhanden ist,
um elektrische Schläge und Schäden am Gerät zu
vermeiden, da der Stabilisator anfangs hohe
Spannungen erzeugt.
