Display brightness adjustment
The display brightness on the HT model can be varied by using the rear panel DIP switches
(SW-5 on the LCI-90, SW-2 on the LCI-90R) to change the scan rate, or by adjusting the
rotary potentiometer (also on the rear panel) marked DISP. The DIP switch settings are
described in Appendix B. Varying the DISP potentiometer is most effective on the higher
scan rates. Decreasing the brightness prolongs the life of the screen.
