Make sure the ground terminal of the DC power supply is grounded. • CONNECTING TO A DC POWER SUPPLY • CONNECTING TO A DC POWER SOURCE • See p. 62 for fuse replacement. • See p.
2 INSTALLATION ■ Antenna installation D Antenna location D Antenna connector To obtain maximum performance from the transceiver, select a high-quality antenna and mount it in a good location. A nonradial antenna should be used when using a magnetic mount. The antenna uses a PL-259 connector. • PL-259 CONNECTOR Roof-mount antenna (Drill a hole or use a magnetic mount.) Gutter-mount antenna Trunk-mount antenna 30 mm ➀ Slide the coupling ring down. Strip the cable jacket and soft solder.
3 SETTING A FREQUENCY ■ Preparation D Turning power ON/OFF ☞ NOTE: Before operating the transceiver for the first time it’s a good idea to reset the transceiver’s CPU. This will ensure that all transceiver settings are at their defaults. See p. 62 for CPU resetting details. Push [PWR] for 1 sec. to turn power ON or OFF. Push [PWR] for 1 sec. D VFO and memory modes The transceiver has 2 basic operating modes: VFO mode and memory mode. Push [V/MHz] to select VFO mode when the transceiver is not in VFO mode.
