Display 31 shows the manual rate menu file option that can be adjusted by pressing and holding the ENTER key to get the double beep tone and the blinking cursor. Type in the new rate, then when finished, press the ENTER key again.

Display 32 shows the menu file option allows you to step the drive tracking frequency setting in tenths of a hertz, by using the PREV and NEXT (up and down arrow) keys. This is a convenient feature if you are trying to match the precise speed of a planet, comet, or any other non-stellar object. To exit this option, press the MODE key.

[ toc ] 5. Mode Five: KEYPAD OFF/ BRIGHTNESS ADJUST

In order to see very faint objects, it will sometimes be necessary to either dim or completely turn off the Keypad red LED backlighting. To do so press the MODE button until the display goes blank. This is the OFF option.

To set the Keypad brightness, press the ENTER button and adjust the brightness to your satisfaction with the PREV and NEXT keys. To exit, press the MODE key.

Note: The backlighting is done by edge lighting a plastic light bar underneath the Keypad. Four LED's are used and do not give a perfectly even backlighting of the keys as keys closer to a LED will be a little brighter than those keys further away.
