• Remote Focus Unit (version 2) Backlight Output Problems 

    If there is no backlight output, there are 2 options for the enduser to choose from:

    1. Check T1 for damage.  If physically damaged or T1 is making a squealing sound, it needs to be replaced by a certified ETC technician.
    2. Check the RFU configuration to see if the backlight timer is on.  The default setting for the timer is: 05 Min., 00 Sec.  To check the configuration, press and hold the top 3 buttons on the numbered portion of the RFU keypad upon boot up ("7, 8, 9" on the EXPN RFU2; "+, Thru, -" on the OBSN RFU2) .  Cycle through each option with the "+" key and enter the desired time when the backlight option is reached.  Press "Enter" when finished.
