1 1 ACCESSOR Y A TT ACHMENT D Antenna CAUTION: T ransmitting without an antenna may damage the transceiver . Insert the supplied antenna into the an- tenna connector and screw down the an- tenna as shown at right. Keep the jack cover attached when jacks are not in use to avoid bad contacts from dust and moisture.
■ Panel description q VOLUME CONTROLS [VOL] (p. 5) T urns power ON and adjusts the audio level. w PTT SWITCH [PTT] (p. 5) Push and hold to transmit; release to receive. e CHANNEL UP/DOWN SWITCHES [ Y ]/[ Z ] ➥ Push to select the operating channel or frequency .
3 2 P ANEL DESCRIPTION ➥ When memory mode is selected, this switch sets the dis- played channel as a scan lock-out channel when pushed for 2 sec. (p. 8) - “SKIP” appears on the display . i SQUELCH SWITCH [SQL] ➥ Push and hold to open the squelch.
4 2 P ANEL DESCRIPTION ■ Function display q MEMOR Y MODE INDICA TOR (p. 9) Appears when memory mode is selected. w LOCK INDICA TOR (p. 6) Indicates that the lock function is in use. e LOW BA TTERY INDICA TOR ➥ Appears when the battery is nearing exhaustion.
5 3 BASIC OPERA TION ■ Receiving and transmitting CAUTION: T ransmitting without an antenna may dam- age the transceiver . q Rotate [VOL] clockwise to turn power ON, then set to the 10 o’clock position. w Push [V/M] to select memory mode or VFO mode.
6 3 BASIC OPERA TION ■ Setting squelch level The transceiver has a noise squelch circuit to mute undesired noise while receiving no signal. ➥ T o open the squelch: Push and hold [SQL] to open the squelch. This is useful to listen to weak signals that do not open the squelch.
7 3 BASIC OPERA TION ■ Dial select function Use the dial select function to adjust the tuning behavior of the [ Y ]/[ Z ] keys—use 1 MHz tuning when you want to change the frequency in large increments; use regular tuning when you want to change the frequency in smaller incre- ments.
8 4 SCAN OPERA TION ■ Memory (lockout) scan Memory scan repeatedly scans all programmed memory channels, except those set as lockout channels. q Push [V/M] to select memory mode, if necessary . • “ ” appears. w Puch [SCAN] to start scan. - T o change the scan direction, push [ Y ] or [ Z ].
9 5 MEMOR Y PROGRAMMING ■ Programming a memory channel The transceiver has 19 memory channels for storage of often -used frequencies. q Push [V/M] to select VFO mode, if necessary . w Push [ Y ] or [ Z ] key to select the desired frequency . • Push [V/M] key one or more times to use the dial select function, if desired.
10 5 MEMORY PROGRAMMING ■ Memory names ï Programming memory names q Select the memory channel to be programmed: ➥ Push [V/M] to select memory mode. ➥ Push [ Y ] or [ Z ] to select the memory channel. w Push [M/W] for 5 sec. to enter memory name writing mode.
11 6 OTHER FUNCTIONS ■ Initial set mode Initial set mode is accessed at power ON and allows you to set seldom-changed settings, in this way you can “customize” transceiver operations to suit your preferences and operating style. D Entering initial set mode q While pushing [V/M] + [ ], turn power ON.
■ Charging precautions NEVER attempt to charge dry cell bat- teries. This will cause internal liquid leakage and damage the battery case and transceiver . NEVER connect two or more chargers at the same time. Charging may not occur under temper- atures of 10°C (50°F) or over tempera- tures of 40°C (104°F).
13 7 BA TTERY P ACKS D Multiple charging with the BC-121 The optional BC-121 allows up to 6 battery packs to be charged simultaneously . Six AD-81 ’ s and an AC adapter (may be supplied with the BC-121 depending on version) are additionally required.
14 7 BA TTERY P ACKS ■ About the battery pack D Operating period Depending on the attached battery pack, the operating period of the transceiver varies.
CLONING 15 8 Cloning allows you to quickly and easyly transfer the programmed contents from one transceiver to another transceiver , or , data from PC to a transceiver using the optional EX-21 19 cloning software.
16 9 TROUBLESHOOTING If your transceiver seems to be malfunctioning, please check the following points before sending it to a service center . POSSIBLE CAUSE SOLUTION REF. No power comes on. • The battery is exhausted. • Bad connection to the battery pack.
