16 3 INST ALLA TION ■ DC power suppl y connection Use a 13.8 V DC power supply with more than 12 A capacity . Make sure the ground terminal of the DC power supply is grounded. • See p . 74 for fuse replacement. ■ Cable connection Connect the cable as sho wn below .
■ Antenna installation D Antenna location T o obtain maxim um perf ormance from the transceiver , select a high-quality antenna and mount it in a good location. A non- radial antenna should be used when using a magnetic mount. D Antenna connector The antenna uses a PL-259 connector .
18 4 FREQUENCY SETTING ■ Preparation D T urning po wer ON/OFF Bef ore operating the transceiv er for the first time it’ s a good idea to reset the transceiv er’ s CPU . This will ensure that all transceiv er settings are at their def aults. See p.
■ Loc k functions T o pre vent accidental frequency changes and unnecessary function access, use the loc k function. The transceiver and HM-98 hav e 2 different loc k functions. D Frequency loc k This function locks the tuning dials and s witches electronically and also locks the microphone s witches.
20 4 FREQUENCY SETTING ■ Using the tuning dial q Select VFO mode with the desired band’ s [V/M H ]. • Push [CHG/L] if [V/M H ] is not display ed. w Rotate desired band’ s [DIAL] to change the frequency . • The frequency changes according to the selected tuning steps .
■ Setting a tuning step T uning steps can be selected f or each band. This transceiver has 8 tuning steps as f ollows: • 5 kHz • 10 kHz • 12.5 kHz • 15 kHz • 20 kHz • 25 kHz • 30 kHz • 50 kHz q Select VFO mode with the desired band’ s [V/M H ].

■ Receiving q Push [PO WER] for 2 sec. to turn power ON. w Set the audio le vel. ➥ Push the desired band’ s [MONI] to open the squelch. • Push [CHG/L] if [MONI] is not displa yed. ➥ Rotate the desired band’ s [V OL] control to adjust the audio output le vel.
24 5 BASIC OPERA TION ■ Monitor function This function is used to listen to weak signals without disturb - ing the squelch setting or to open the squelch manually e ven when mute functions such as the tone squelch are in use. ➥ Push the desired band’ s [MONI] to toggle the monitor func- tion ON and OFF .
25 5 BASIC OPERA TION ■ Selecting output power The transceiv er has 4 output po w er le vels to suit y our oper at- ing requirements. Low output powers during shor t-distance communications ma y reduce the possibility of interference to other stations and will reduce current consumption.
■ Accessing a repeater When using a repeater , the transmit frequency is shifted from the receive frequency b y the offset frequency . (p. 30) It is con- venient to prog ram repeater inf ormation into memor y chan- nels. (p . 32) q Select the desired band with the desired band’ s [MAIN].

29 6 REPEA TER OPERA TION ■ Subaudible tone (encoder function) Some repeaters require subaudible tones to be accessed. Subaudible tones are superimposed ov er your normal signal and must be set in adv ance. Each operating band and each memor y channel hav e inde- pendent settings.
30 6 REPEA TER OPERA TION ■ Offset frequency When communicating through a repeater , the transmit fre- quency is shifted from the receiv e frequency by an amount determined by the offset frequency . q Select the mode/channel you wish to set the offset fre- quency to , such as VFO mode or memor y/call channel.
31 6 REPEA TER OPERA TION ■ A uto repeater function (U .S.A. and Korea versions onl y) The U .S.A. and K orea versions automatically activ ate the re- peater settings (duple x ON/OFF , duplex direction, tone en- coder ON/OFF) when the operating frequency f alls within or outside of the general repeater output frequency range .
