Lamp

It is recommended that the lamp (sold separately) be replaced when the remaining lamp life be-
comes 5% or less, or when you notice a significant deterioration in the picture and color quality.
The lamp life (percentage) can be checked with the on-screen display. See page 44.

For lamp replacement, please consult your nearest Sharp Authorized Projector Dealer or Service
Center.
IMPORTANT NOTE TO U.S. CUSTOMERS:
The lamp included with this projector is backed by a 90-day parts and labor limited warranty. All service
of this projector under warranty, including lamp replacement, must be obtained through a Sharp Autho-
rized Projector Dealer or Service Center. For the name of the nearest Sharp Authorized Projector Dealer
or Service Center, please call toll-free: 1-888-GO-SHARP (1-888-467-4277).
U.S.A. ONLY
Caution Concerning the Lamp

This projector utilizes a pressurized mercury lamp. A loud sound may indicate lamp failure. Lamp
failure can be attributed to numerous sources such as: excessive shock, improper cooling, surface
scratches or deterioration of the lamp due to a lapse of usage time. The period of time up to failure
largely varies depending on the individual lamp and/or the condition and the frequency of use. It is
important to note that failure can often result in the bulb cracking.

When the lamp replacement indicator and on-screen display icon are illuminated, it is recommended
that the lamp be replaced with a new one immediately, even if the lamp appears to be operating
normally.

Should the lamp break, the glass particles may spread inside the lamp cage or gas contained in the
lamp may be vented into the room from the exhaust vent. Because the gas in this lamp includes
mercury, ventilate the room well if the lamp breaks and avoid all exposure to the released gas. In
case of exposure to the gas, consult a doctor as soon as possible.

Should the lamp break, there is also a possibility that glass particles may spread inside of the
projector. In such a case, it is recommended you contact your nearest Sharp Authorized Projector
Dealer or Service Center to remove the damaged lamp and assure safe operation.
Replacing the Lamp
Caution
•Do not remove the lamp unit immediately after operation of the projector. The lamp will be hot and touching
it can lead to burn or injury.
•Wait at least one hour after the power cord is disconnected to allow the surface of the lamp unit to fully cool
before removing the lamp unit.

If the new lamp does not light after replacement, take your projector to the nearest Sharp Autho-
rized Projector Dealer or Service Center for repair. Purchase a replacement lamp unit of type BQC-
PGA20X//1 from your nearest Sharp Authorized Projector Dealer or Service Center. Then carefully
change the lamp by following the instructions described in this section. If you wish, you may have
the lamp replaced at your nearest Sharp Authorized Projector Dealer or Service Center.

COMMANDPARAMETERRETURN
BUTTONS & REMOTE CONTROL KEY
PC control
A computer can be used to control the projector by connecting an RS-232C serial control cable (cross type,
sold separately) to the projector. (See page 20 for connection.)
Communication conditions
Set the serial port settings of the computer to match that of the table.
Signal format: Conforms to RS-232C standard. Parity bit: None
Baud rate: 9,600 bps Stop bit: 1 bit
Data length: 8 bits Flow control: None
Basic format
Commands from the computer are sent in the following order: command, parameter, and return code. After
the projector processes the command from the computer, it sends a response code to the computer.
Info
•When more than one code is being sent, send each command only after the response code for the previous
command from the projector is verified.
Note
•When the projector is put into the standby mode, a message “Shutting Down. Please Wait.” is displayed for
about 20 seconds. At that time, if the “POWR_ _ _1” command is being sent, “ERR” will be returned and this
command is not received.
Commands
Example: When turning on the projector, make the following setting.
