Optional Lens Installation
This section describes how to install the lens.
Before installation
* Determine the optional lens to be used to obtain a desired projection distance. There are six optional lenses available:
GT13ZLB, GT19ZL, GT20ZL, GT24ZLB and GT34ZLB (Zoom lens)
GT10RLB (Short throw fixed-focus lens)
* Press the power button (ON/STAND BY) on the projector or POWER OFF button on the remote control for a minimum of two seconds to turn off the
power, wait 90 seconds (2 minutes in the optional Long Life lamp 001-716) for the cooling fan to stop, turn off the main power switch then disconnect
the power cable.
Check that the projector has cooled off sufficiently before proceeding.
CAUTION
* The projector and lens contain high-precision parts. Do not induce shock to the projector or the lens.
* Do not touch the lens surface. Doing so can degrade the optical performance.
