It is recommended to ask an authorized engineer to replace the lamp unit. Contact your dealer. Consult your dealer to purchase a replacement lamp unit. (for PT-LW321E / PT-LW271E / PT-LX271E: ET-LAL330; for PT-LX351E: ET-LAL340; for PT-LX321E: ET-LAL331) CAUTION: ■ Do not replace the lamp unit when it is hot. (Wait at least 1 hour after use.) The inside of the cover can become very hot, take care to avoid burn inj\ uries. 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.

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- LX351E, 4 000 hours for PT-LX321E, 4 500 hours for PT-LW321E, and 5 000 hours for PT-LW271E / PT- LX271E. However, this may be shortened depending on individual lamp characteristics, usage conditions, and the installation environment. Therefore, it is strongly recommended that a replacement lamp unit be pr\ epared. 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-LX351EOver 2 970 hoursIf the lamp is used over 2 970 hours, the warning message will appear.

Used for PT-LW321E zThe used lamp time is calculated internally in the following formula as the used time in each setting of [Normal], [Auto] and [ECO] in [Lamp power mode]: Lamp runtime = (Lamp runtime of [Normal] × 60 + Lamp runtime of [Auto] × 27 + Lamp runtime of [ECO] × 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).
