Panasonic LCD Projector Pt Vw350zu Pt Vx420zu Operating Instructions

							Notes on the replacement of the lamp unit
 
f The luminous source of the lamp is made of glass and may burst if you hi\
t it against a hard surface or drop it. Please handle 
with care.
 
f A Phillips screwdriver is required for replacement of the lamp unit.
 
f When replacing the lamp unit, be sure to hold it by the handle.
 
f When replacing the lamp because it has stopped illuminating, there is a possibility that the lamp may be broken. If replacing 
the lamp of a projector which has been installed on the ceiling, you sho\
uld always assume that the lamp is broken, and you 
should stand to the side of the lamp cover, not underneath it. Remove the lamp cover gently. Small pieces of glass may fall 
out when the lamp cover is opened. If pieces of glass get into your eyes\
 or mouth, seek medical advice immediately.
 
f The lamp may be ruptured. Care should be taken not to scatter pieces of the broken lamp glass when replacing the lamp 
unit. Pieces of the broken lamp may fall from the lamp unit especially w\
hen the projector is mounted on the ceiling, so when 
replacing the lamp unit do not stand directly underneath it or position \
your face close to it.
 
f The lamp contains mercury. Consult your local municipality or your dealer about correct disposal of used lamp units.
Attention
 
f Panasonic takes no responsibility for any damage or malfunction of the p\
roduct resulting from use of lamp units which are 
not manufactured by Panasonic. Use only specified lamp units.
Note
 
f The model numbers of accessories and optional accessories are subject to\
 change without prior notice.
When to replace the lamp unit
The lamp unit is a consumable component. Since its brightness gradually \
decreases over time, it is necessary to replace the 
lamp unit regularly. The estimated duration before replacement is 5 000 hours, but the lamp may go off before 5 000 hours has 
elapsed depending on individual lamp characteristics, usage conditions, \
and the installation environment. It is recommended 
that the Replacement lamp unit be prepared earlier.
If you continue to use the lamp unit after 5 000 hours has elapsed, the lamp turns of f automatically after approximately 10 
minutes, as it will cause malfunction of the projector.

Over 5 000 hours If the power is turned on without replacing the lamp, the 
power automatically turns off after approximately ten min
-
utes to prevent the malfunction of the projector.
Note
 
f To predict when to replace the lamp, check the lamp runtime displayed in [RUNTIME] in [STATUS] (x page 69) .
 
f 5 000 hours of use is a rough guideline, but is not a guarantee. The lamp runtime differs depending on the setting of "LAMP 
POWER" menu.

Attention
 
f If a command is transmitted after the lamp starts illuminating, there ma\
y be a delay in response or the command may not be 
executed. Try sending or receiving any command after 60 seconds.
 
f When transmitting multiple commands, be sure to wait until 0.5 seconds has elapsed after receiving the response from the 
projector before sending the next command. When transmitting a command which does not need a parameter , a colon (:) is 
not necessary.
Note
 
f If a command cannot be executed, the “ER401” response is sent from the projector to the computer .
 
f If an invalid parameter is sent, the “ER402” response is sent from the projector to the computer .
 
f ID transmission in RS-232C supports ZZ (ALL) and 01 to 06.
 
f If a command is sent with a specified ID, a response will be sent to the computer only in the following cases.  
- It matches the projector ID. 
- [PROJECTOR ID] ( x page 69) is set to [ALL].
