■ Digital mode operationThe IC-V82/U82 with optional digital unit UT-118 can be op-erated for digital voice mode and low-speed data operationfor both transmit and receive. Also available for connectingGPS receiver (compatible with an RS-232C output/NMEA for-mat/4800 bps) and transmit/receive position data.■ Call sign programmingFour kind of call sign memories are available for your own callsign “myC,” other station call sign “yUC” and nearest repeatercall sign “R1C” and another zone’s repeater call sign “R2C.”Each call sign memory can be stored up to 6 call signs, andeach call sign programmed up to 8 characters.DD Your call sign programmingYour call sign must be programmed for both Digital voice andlow-speed data communications (including GPS transmis-sion).q Push [A•FUNC] and [0•OPT] to enter OPTION SET MODE, thenpush [YY] or [ZZ] several times to select the call sign selectmode.• “myC” appears.w Push [0• OPT] for 1 sec. then rotate [VOL] to select the de-sired call sign channel.e Push [YY] (or [ZZ]) to set into call sign programming condition.• The 1st digit blinks and channel indication stops blinking.r Rotate [VOL] to set the desired character or code.• Push [ZZ] or [YY] to move the cursor to left or right, respectively.t Push [YY] (or [ZZ]) to select 2nd digit, then rotate [VOL] toset the desired character or code.• 2nd digit blinks (1st digit stops blinking).• Repeat this step for programming your call sign.y Push [0• OPT] to fix the call sign.u Rotate [VOL] to select an another channel from “C1” to“C6.”i Repeat steps w to u to program your call sign channels.40DIGITAL MODE OPERATION11 Required Optional UT-118NOTE: All digital (DV) mode operation/settings are re-quired an optional digital unit UT-118. The transceiver with-out UT-118 does not indicate any items for the digital (DV)mode that described in this section.
