■ Digital mode operationThe IC-V82/U82 with optional UT-118 DIGITAL UNIT can be op-erated for digital voice mode and low-speed data operationfor both transmit and receive. It can also be connected to aGPS receiver (compatible with an RS-232 output/NMEA for-mat/4800 bps) and transmit/receive position data.■ Call sign programmingFour types of call sign memories are available for your owncall sign “myC,” other station call sign “yUC,” nearest repeatercall sign “R1C” and another zone’s repeater call sign “R2C.”Each call sign memory can store up to 6 call signs, and eachcall sign programmed up to 8 characters.DD Your own call sign programmingYour own call sign must be programmed for both digital voiceand low-speed data communications (including GPS trans-mission).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 and hold [0• OPT] for 1 sec. then rotate [VOL] to se-lect the desired call sign channel.e Push [YY] to select call sign programming mode.• 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] to select 2nd digit, then rotate [VOL] to selectthe desired character or code.• 2nd digit blinks (1st digit stops blinking).• Repeat this step for programming your own call sign.y Push [0• OPT] to save the call sign.u Rotate [VOL] to select an another channel from “C1” to“C6.”i Repeat steps w to u to program your own call sign channels.42DIGITAL MODE OPERATION11 Requires Optional UT-118NOTE: All digital (DV) mode operation/settings require anoptional UT-118 DIGITAL UNIT. A transceiver without UT-118does not indicate any items for the digital (DV) mode de-scribed in this section.
