Tips on Adjusting Focus for Lens Memory Function
Optimum focus for lens memory function can be achieved on the projector by paying special attention in a few areas.
Focus adjustment after the projector has warmed up to normal operating temperature is better than doing so when the projector is cold.
Lens mechanics interact differently when adjusting focus from one direction to the other.
For this reason final focus adjustments should be done in a specific direction.
For optimum focus of lens memory function, follow the steps below.
For the zoom and the lens shift adjustment, perform the normal procedures.
See the Lens Memory section on page E-33 for storing the adjustment data.
Preparation (Recommend) :
Warm up the projector for about 60 minutes.
Adjusting the Focus
1) Practice focusing
Use the FOCUS (+) or (-) button on the projector or the remote control to increase the focus values or decrease the focus values to
verify the accuracy of focusing.
2) Try optimizing defocus
Use the FOCUS button (-) to decrease the focus values until pixel patterns are too blurry to be visible.
3) Obtain correct focus
Use the FOCUS button (+) to obtain the best focus. Do not use the FOCUS (-) button at this time.
Finally store the adjustments in memory.
If you adjust beyond the best focal point, go back to step 2) and repeat the procedures. Always adjust the focus from the negative
direction towards the positive direction.
NOTE 1: The Lens Memory function is available on the two optional lenses TL-1ZH/1Z or TL-2Z only.NOTE 2: The Lens Memory function is not available in the Link mode.
