Panasonic DLP Based Projector PT-D7500U PT-D7600U Operating Instructions

							71
Lamp select
Two internal lamps in the projector can be used either
in “DUAL” or “SINGLE” mode depending on users
needs or viewing conditions.
In the “SINGLE” mode, the projector may automatically
switches between one lamp and the other, or one of
the lamps can be specified.
“DUAL”: Two lamps illuminate.
“LAMP 1”: One lamp illuminates.
(Lamp Unit 1 is always used)
“LAMP 2”: One lamp illuminates.
(Lamp Unit 2 is always used)
“SINGLE”: One of the lamps illuminates.
(The lamp with shorter operating hours is automatically
selected)
Lamp power
The luminance of the projection lamp can be changed
depending on users needs or the viewing conditions.
“HIGH”: Set when high brightness is necessary.
“LOW”:  Set when high brightness is not necessary.

Note• When set to “LOW”, it is possible to
reduce power consumption, reduce
operating noise and extend lamp
service life.Note
• When set to “SHORT”, operating noise
increases a little.• If any of “LAMP 1”, “LAMP 2” and
“SINGLE” has been selected, when a
currently lit lamp expires, or is turned
off due to the elapsed time of lamp
lighting exceeding 1500 hours, the
other lamp will be turned on.
If “DUAL” has been selected, when
either of the two lamps expires, or is
turned off due to the elapsed time of
lamp lighting exceeding 1500 hours,
the other lamp with elapsed time not
exceeding 1500 hours continues
lighting.
Further, if the elapsed time exceeds
1500 hours for both lamps, the
projector will enter a standby state.
• If only one lamp is mounted, select
“LAMP 1” or “LAMP 2” according to
the relevant lamp unit.
In “LAMP 1” or “LAMP 2” mode, if the
corresponding lamp is not installed,
the other lamp will turn on.
• If the lamp selection is changed,
picture is muted during lamp switching
execution. (7-25sec.)(Approx. 160 secs.)

How to switch the input impedance (signal level) of the synchronization signal
When the ET-MD95RGB input module (sold separately) is mounted, the user can switch the input impedance
(signal level) of the synchronization signal with the analog RGB input.
Choose 75 Ωwhen connecting with the equipment whose synchronization output impedance is 75 Ωsuch as a
signal selector, or switch to HI-Z (TTL) when connecting with the equipment whose synchronization output is TTL
such as a video card of a PC.

• If a wrong command is received, the projector will send an “ER401” command to the computer.
• Projector ID supported on the RS-232C interface is ZZ (ALL) and a group of 1 to 64 and 0A to 0Z.
• If a command is sent with a projector ID specified, the projector will return answer back only in the
following cases:
If it coincides with the projector ID,
ID specification is ALL and VPS-SYSTEM is the master, or
ID specification is group and Group is the master. • No command can be sent or received for 10 to 60 seconds after the lamp starts lighting. Try
sending any command after that period has elapsed.
• When sending several commands, be sure to wait for a response from the projector before sending
the next command. When sending commands without parameters, a colon (:) is not necessary.
