c Optional Lens Installation
This section describes how to install the lens.
See page 2-8 for installing the GT12ZLB lens and page 2-10 for the GT06RLB lens.
Before installation
* Determine the optional lens to be used to obtain a desired projection distance. There are nine optional lenses available:
GT12ZLB, GT13ZLB, GT19ZLB, GT20ZL, GT24ZLB, GT34ZLB and GT48ZLB (Zoom lens)
GT06RLB and 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 extended life lamp GT60LPS) 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.
