Switch off the power and remove battery pack. Remove three (3) screws from the back of the transceiver. Locate the DC and MIC jacks and remove the plugs. Carfully seperate lower part of the back cover and remove from the handheld. 2. Remove the inner partition. First lightly push the charging electrodes and pass them through the holes of the inner partitiom. 3. Remove antenna, VOL and Tuning control knobs. Remove rubber cover from top of radio. 4.Remove inner assembly and locate green wire soldered to two (2) pads behind the Volume control on the PC board. Carfully unsolder one side of the green wire, tape that end off so it will not come in contact with any other part of the circuit. 5. Reassemble the radio, reset the microprocessor by pressing [F] and the Power on switch at the same time. This should allow transmit operation from 136.00 MHz to 173.995 MHz. Remember, unless you have authorization to transmit outside the amateur frequencies, you can risk losing your hard earned license.
