• Pressing-and-holding F1, F3 and F5 simultaneously while powering up the radio will cause defaults to be loaded. The user must either disconnect power to retain the old settings or press-and-hold the POWER button to overwrite them with defaults. All configurations, adjustments, frequencies and mode settings will be lost!

• Pressing-and-holding a button (other than POWER) while powering up the radio will cause it to enter a “button test” mode. If multiple keys are pressed, only the name of the button with the highest precedence will be displayed. In decreasing order, the precedence is: M2, G3, G2, BNDM, G4, M3, STEPM, STEPP, M1, M3, F1, F2, F4, BNDP, F5, G1 and POWER
• The“Band-” and “Band+” and the “Step-” and “Step+” functions may be swapped using menu selections.
