1 PANEL DESCRIPTION ■ Function display q w e t TX INDICATOR (p. 5) Appears while transmitting. r t !1 y FREQUENCY DISPLAY (p. 11) ➥Shows the operating frequency. ➥Shows the channel name when the memory name function is selected. (p. 10) y o i u q MEMORY MODE INDICATOR (p. 5) Appears when memory mode is selected. w DUALWATCH INDICATOR (p. 7) Indicates when the dualwatch function is activated. e SCAN INDICATOR (p. 8) Indicates when the scan function is selected. r BUSY INDICATOR (p.
BASIC OPERATION ■ Power ON ■ Channel selection q Push [POWER] to turn power ON. ï VFO/Memory selection w Operate the transceiver as indicated in the following sections. e Select the desired memory channel (or VFO frequency) with the [V/M] keys. • When receiving a signal, appears and audio is emitted from the speaker. • Further adjustment of audio level may be necessary at this point. • Push [SQL] to adjust the squelch level. (p. 6) • Push and hold the tuning dial for 1 sec.
2 BASIC OPERATION ■ Squelch function ■ Dial select function The transceiver has a noise squelch circuit to mute undesired noise while receiving no signal. Use the dial select function to adjust the tuning behavior of the [DIAL] keys—use 1 MHz tuning when you want to change the frequency in large increments; use regular tuning (25 kHz or 8.33* kHz) when you want to change the frequency in smaller increments.
3 SCAN OPERATION ■ Scan operation • VFO scan q Push [V/M] to select memory mode or VFO mode, if necessary. • “ MR ” appears on the memory mode. w Make sure the squelch level is set to the threshold point. • Set a squelch level (01 to 25) where the noise is muted. Repeatedly scans all frequencies over the entire band. Scan step is minimum channel spacing. (eg 25 kHz or 8.33* kHz) *Except USA version lowest frequency highest frequency Start Scan Jump e Push [SCAN] to start scan.
3 SCAN OPERATION ■ On–hook scan ■ Dualwatch On–hook scan (Hanger scan) is available when taking the microphone from its hanger (off–hook) and /or returning it into the hanger (on–hook). q Push [SCAN] to start scanning. w When receiving a signal, scan pauses until the signal disappears. ➥ • You can converse by taking the microphone from the hook. e Place the microphone on the hook to restart scanning. r Scan restarts 2 sec. after the signal disappears even if you did not converse the station.
MEMORY PROGRAMMING ■ Programming a memory channel D Setting lock out channels The transceiver has 20 memory channels for storage of often -used frequencies. q Push [V/M] to select VFO mode, if necessary. w Turns the [DIAL] to select the desired frequency. q Push [V/M] to select memory mode, if necessary. • Push [DIAL/TS] one or more times to use the dial select function, if desired. e Push [V/M] for 5 sec. to enter memory programming mode. • “ MR ” and memory channel number appear.
4 MEMORY PROGRAMMING ■ Memory names ï Programming memory names q Select the memory channel to be programmed: ➥ Push [V/M] to select memory mode. ➥ Turns [DIAL] to select the memory channel. w Push [V/M] for 5 sec. to enter memory name writing mode. NOTE: •Push PTT switch to abort the programming memory name. • The following characters can be used in names: ➥ 0 to 9, A to Z (capitals), (space), $, %, ’, (, ), ✽, +, “ , ”, –, /, <, =, >, ?, @, [, \, ], ^, _ and `.
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. 5 D Beep tones ON/OFF Confirmation beep tones normally sound when you push a key. These can be turned ON or OFF as you prefer. D Entering initial set mode q While pushing and holding [V/M] + [TS(DIAL)], push [POWER] sw to turn power ON.
5 OTHER FUNCTION D Priority channel The priority channel is used to store your most often-used channel for quick recall. In addition the priority channel is monitored during priority scan modes. The default setting for the priority channel will differ depending on pre-programming. ➥ Push [PRI] to toggle the priority channel mode or previous mode. • Setting the priority channel q While pushing and holding [V/M] and [DIAL(TS)], push [POWER] to turn the power ON. • The transceiver enters initial set mode.
CONNECTION AND INSTALLATION ■ Rear panel and connections 6 Antenna › External speaker jack ⁄ ¤ fi OPC-871 HEADSET ADAPTER (Option) ‹ red: + Supplied DC power cable q Connects to an antenna Ask your dealer about antenna selection and best installation location.
