[. . . ] 6) *NOTE: The VFO/memory switch [V/M] and the memory write switch [M/W] functions may not be available depending on version. 3 BASIC OPERATION I Power ON q Push [POWER] to turn power ON. 2 I Channel selection ï VFO/Memory selection q Push [V/M] to select memory mode or VFO mode. Rotate the dial to select a desired frequency/channel. w During memory mode operation, push [V/M] key to transfer the memory contents to VFO. · Push [V/M] to select VFO mode. 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. 6) · Push and hold the tuning dial for 1 sec. to select the [TS], each push increments/decrements to the frequency are either 10 kHz or 1 MHz. 7) NOTE: Only frequency data is transferred even if the memory channel has a memory name. ï External speaker output control External speaker output can be turned OFF, if desired. w Rotate the dial to select "SP OFF". e Push [SQL] to turn to the previous mode. NOTE: This function available both internal and external speakers. 4 r Push and hold [PTT] to transmit, then speak into the microphone. · Transmit indicator lights. t Release [PTT] to receive. 2 BASIC OPERATION I Squelch function The transceiver has a noise squelch circuit to mute undesired noise while receiving no signal. I Dial select function Use the dial select function to adjust the tuning behaviour 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. · 1 MHz tuning or regular tuning steps can be selected. (see diagrams at right) e Push and hold [DIAL(TS)] for 1 sec. to return to normal operation. D Setting the squelch level q Push [SQL] to turn the level adjusting mode ON. w Turn the tuning [DIAL] to select the squelch level. · `SQ 01' is loose squelch and `SQ 25' is tight squelch. (Initial level is `SQ 01') · `SQ 01' indicates that the squelch circuit is turned off. ·" " appears on the display. e Push [SQL] to return to regular operation. 1 MHz tuning selected I Side tone function When using an optional headset, such as those from the David Clark Co. via the OPC-871 HEAD SET ADAPTOR, the transceiver outputs your transmitted voice to the headset for monitoring. 17) Regular tuning selected I LCD backlight control The backlight of the can be set OFF, Low or High.
