4610 SUB-RECEIVERThe “ ” and “ ” icons are both on the sub-receiver display:• You can do all the above, plus transmit on theSUB band frequency.This transceiver provides many other methods forselecting a frequency quickly. For further details, referto “SELECTING YOUR FREQUENCY” {page 37}.SUB-RECEIVER PANEL METERThe multifunction meter measures the parametersdescribed in the table below. The S-meter appearswhen in receive mode and the PWR meter appearswhen in transmit mode. Peak readings for theS- meter and PWR functions are held momentarily.elacS yalpsiD etatSnoitcnuFS htgnertslangisdevieceR evieceRRWP rewoptuptuotimsnarT timsnarTNote: Peak Hold readings cannot be deactivated.SELECTING A MODE FOR THE SUB-RECEIVERFirst, confirm that the “ ” icon is on the SUB banddisplay. If it is not, press [SUB] or [CTRL] to assignthe function controls to the SUB band.The SUB band can only be used to transmit in FMmode and receive in FM or AM mode. Press [FM/AM/ NAR] to toggle the operating mode for the sub-receiver. The narrow bandwidth operation for AM isnot available for the SUB band frequency. Refer to“Narrow Bandwidth for FM” {page 29} for FMoperation.FM CTCSS OPERATIONYou can assign an independent CTCSS tone to thesub-receiver. Refer to FM CTCSS OPERATION{page 35} for function and control details.FM DCS OPERATIONYou can assign an independent DCS code to the sub-receiver. Refer to FM DCS OPERATION {page 36}for function and control details.TONE FREQ. ID SCANThis function scans through all the tone frequenciesin order to identify the incoming tone frequency onthe receiving signal of the sub-receiver. Refer toTONE FREQ. ID SCAN {page 34} for function andcontrol details.DCS CODE ID SCANThis function scans through all the DCS codes inorder to identify the incoming DCS code on thereceiving signal of sub-receiver. Refer to DCS CODEID SCAN {page 36} for function and control details.• Holding down the key changes the bandscontinuously.• If “MHz” is visible on the display, first press[1MHz] to exit from the 1MHz Step Up/ Downmode.ADJUSTING THE AUDIO FREQUENCY (AF) GAINTurn the SUB AF control clockwise to increase theaudio level and counterclockwise to decrease thelevel.SUBCALLC.INUTOSBSBSUBSEL1MHz CTRLMRM VFOMG.SELM.INM.INQUICK MEMOSATLA/BM/S REVTRACEMAINMANUALRFAFSQLSUBCHMULTIBC MAINGAINVFO/CHVFO/M A=BSPLITMENU TF-SETMAIN SUBSG.SELSCANRITCW TUNE 9.6k STARIT/SUBCONXITALTSETCLEARP.C.T_ +HF/VHE/UHF ALL MODE MULTI BANDER TS-2000AFSQLNote: The position of the SUB AF control does not affect the volumeof beeps caused by pressing buttons.

The SUB bandLED turns off when the squelch is ON.SELECTING A FREQUENCYWhen you operate both the main transceiver and thesub-receiver at the same time, you will be in one ofthe following conditions. First, check where the “ ”and “ ” icons are on the display, then follow theinstructions below.The “ ” and “ ” icons are both on the MAIN banddisplay:• Turn the RIT/ SUB control to adjust the sub-receiver frequency.“ ” is on the SUB band display and “ ” is on theMAIN band display:• Turn the RIT/ SUB control to adjust the sub-receiver frequency.“ ” is on the MAIN band display and “ ” is on theSUB band display:• Turn the RIT/ SUB control, the MULTI/ CH control,or the MAIN control to adjust the frequency. Or,directly enter the frequency using the numerickeypad {page 37}. However, the input frequencymust be within the sub-receiver frequency range.The frequency you selected may round up to thenearest workable frequency step size {page 37}.You cannot transmit on the sub-band frequency.
