  • FIRST CHOICE VICTOR 888 Controller unable to calibrate

    Dear FRC First CHoice,

    I received 4 - Victor 888 controllers per my selection. Hooray!. I was able to re-calibrate 3 of the units
    but not the 4th unit. It does not seem to work as expected. How do I get a replacement?

    Best regards,

    Re: FIRST CHOICE VICTOR 888 Controller unable to calibrate

    Hi Marc,

    Can you confirm that the calibration button is working? The easiest way to know is:

    Resetting Calibration to Factory Pre-calibration:
    1. Power OFF the speed controller.
    2. Press and hold the Cal button.
    3. While continuing to hold the Cal button, Power ON the speed controller.
    4. A flashing GREEN indicator denotes calibration is reset. Release the Cal button.

    If this does not work, try working the button a few times. It may be sticking. If the button is working, what step is calibration failing in the following steps?

    User Calibration:
    1. Power ON the speed controller.
    2. Press and hold the Cal button. After a moment, the LED indicator on the Victor will begin alternating between RED and GREEN to indicate a cal mode.
    3. While continuing to hold the Cal button, move the joystick to the maximum and minimum positions. This can be done in any order and as many times as desired.
    4. While continuing to hold the Cal button, return the joystick to center (neutral position).
    5. Release the Cal button.
    6. A flashing GREEN indicator confirms a successful calibration.
    7. A flashing RED indicator denotes an unsuccessful calibration.

    An unsuccessful calibration occurs when either:
    a) Insufficient joystick travel was detected in forward and/or reverse.
    b) The trim tab is too far from center.
    c) The Joystick is too far from center when Cal is released.

    Let us know what does/doesn't happen when you go through these steps.

    Thanks,
    Kate
