Power Supply
Your MFJ-1278 is supplied with an AC adapter. Plug the power supply into a 110 VAC outlet and
plug the 2.1 mm coaxial plug into "POWER" jack locate at the rear of the MFJ-1278.
For operation on AC line voltage other than 110 V AC, you must obtain a suitable AC adapter
which will provide 12 VDC at 500 mA to operate your MFJ-1278.
If it is necessary for you to wire the 2.1 mm coaxial plug for your power supply, wire the 2.1 mm
plug so that the center pin is positive and the outside sleeve is ground.
