MFJ-925 Super-Compact IntelliTuner Automatic Antenna Tuner Instruction Manual

In Case of Difficulty

If the tuner acts erratic, reset the tuner to factory defaults.

If the tuner fails to tune, please double check all connections and follow the tuning procedures again. Be

sure you are using enough inductance (through manual adjustment) and minimum capacitance.

If the tuner arcs at the rated power levels, please double check all connections and follow the tuning

procedures again. Ensure you are not exceeding the tuner’s rated power handling capability. Be sure you

are using the least amount of inductance and the greatest capacitance possible that still allows matching

the load on the operating frequency.

Note: If the tuner arcs when operating on the 160-meter band, it may be necessary to reduce

transmitter output power.

If you are still unsuccessful, but the tuner does adjust and operate when used with a dummy load or

another antenna, please read “Grounding Hints” and “Antenna System Hints” on page 13.
