f Since the luminous lamp is made of glass, it may burst if dropped or hit with a hard object. Handle with care.
f Do not disassemble or modify the lamp unit.
f When replacing the lamp unit, be sure to hold it by the handle because its surface is pointed and its shape is

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 reaching to 5 000 hours, depending on the characteristics of the individual lamp, 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 off automatically after approximately
10 minutes, as it may cause malfunction of the projector.
The message is displayed for 30 seconds. If you press any button
Over 4 800 hours on the control panel or the remote control within 30 seconds, the
message disappears.
Over 5 000 hours The message remains displayed until you press any button.
Note
f To predict the lamp unit replacement time, convert the runtime of [NORMAL], [ECO1] and [ECO2], which are set from the [PROJECTOR
SETUP] menu → [LAMP POWER], to the equivalent runtime of [[NORMAL] respectively. After checking the runtime of [NORMAL], [ECO1]
and [ECO2] displayed in the [PROJECTOR SETUP] menu → [STATUS] → [RUNTIME] → [LAMP (ET-LAV400)], calculate the converted
runtime by referring to "Formula for lamp unit replacement time (rough estimate)". (
f The lamp unit replacement time of 5 000 hours is a rough guideline instead of a guarantee.
