Maintenance
Notes on the replacement of the lamp unit J
The luminous source of the lamp is made of glass and may burst if you hi\
t it against a hard surface or drop  z
it. Please handle with care.
A Phillips screwdriver is required for replacement of the lamp unit. z
Be careful of hands slip when you using a screwdriver. z
When replacing the lamp unit, be sure to hold it by the handle. z
When replacing the lamp because it has stopped illuminating, there is a \
possibility that the lamp may be  z
broken. If replacing the lamp of a projector which has been installed on\
 the ceiling, you should 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.
The lamp contains mercury. Consult your local municipality or your dealer about correct disposal of used  z
lamp units.
Attention
Be sure to use the lamp unit specified. z
Note
The part numbers of accessories and separately sold components are subje\
ct to change without notice. z
When to replace the lamp unit J
The lamp unit is a consumable component. Brightness decreases according \
to duration of usage, so 
periodical replacement of the lamp unit is necessary. The estimated duration before replacement is 3 000 
hours for PT-TW330E / PT-TX300E, 4 000 hours for PT-TW240E. However, this may be shortened depending 
on individual lamp characteristics, usage conditions, and the installati\
on environment. Therefore, it is strongly 
recommended that a replacement lamp unit be prepared.
When the projection lamp of the projector reaches its end of life, the w\
arning message appears on the screen. 
Replace the lamp with a new one promptly.
Model nameLamp runtime
On screen:Warning Lamp message
PT-TW330E / 
PT-TX300EOver 2 970 hoursIf the lamp is used over 2 970 hours, the warning message will 
appear. When any button is pressed, the message will disappear. 
PT-TW240EOver 3 970 hoursIf the lamp is used over 3 970 hours, the warning message will 
appear. When any button is pressed, the message will disappear. 
Attention
If [Lamp Life Reminder] is set to [Off], the lamp warning message will not be displayed when the lamp used time reaches  z
the end of lamp life. In this case, please check the lamp life with the values at the [Lamp Hours Used (Normal)] and [Lamp 
Hours Used (ECO)].
Note
The usage period of  z3 000 hours / 4 000 hours is a rough estimate and is not guaranteed.Used for PT-TW330E/TX300E  zThe used lamp time is calculated internally in the following formula as the used time in each setting of [Normal], [Auto], [ECO1] and [ECO2] in [Lamp power mode]: Lamp runtime =  (Lamp runtime of [Normal] × 60 + Lamp runtime of [Auto] × 24 + Lamp runtime of [ECO1] or [ECO2] × 45) ÷ 60
  In order to estimate the lamp life, please refer to [Lamp Hours Used (Normal)] and [Lamp Hours used (ECO)] in the [Lamp settings] menu (Æ page 41). [Lamp Hours Used (ECO)] is a total real time under [Auto], [ECO1] and 
[ECO2] lamp power modes. Please note that they are not displayed individually .
  
Lamp use time =  ([Lamp Hours Used (Normal)] × 60 + [Lamp Hours Used (ECO)] × α1) ÷ 60
    When setting under both [Normal] and [ECO1]/[ECO2], not using [Auto]: α1 = 45
  
When setting under both [Normal] and [Auto], not using [ECO1]/[ECO2]: α1 = 24
  
When setting under both [ECO1]/[ECO2] and [Auto]: 24 < α1 < 45
 
               The ratio of α1 will be smaller if the used time of [Auto] is more than that of [ECO1]/[ECO2].
