Self Test
A self-test routine will check the functions of the MFJ-926B. This routine checks the LEDs, the internal
buttons, the internal memory, and the power-down circuitry. During the self-test, you may stop the test
by turning off the unit; however, this should NOT be done during the memory test or the memory could
be corrupted. The self-test can be completed in approximately 10 seconds.
Note: Performing the self-test will reset the unit to its factory default settings.
Here is the self-test procedure:
1. Turn off the power to the tuner.
2. Press and hold
only the [TUNE] button while turning the power on.
3. The test begins by blinking the firmware version number via the two front panel LEDs. The
green LED blinks first, followed by the red LED. The version number X.Y is represented by the
number of times the green LED blinks for X and the number of times the red LED blinks for Y.
For example, green LED blinks one time and red LED blinks two times represent firmware
version number 1.2. This also tests the two LEDs.
