4710 SUB-RECEIVERATTENUATORThe attenuator reduces the level of received signals.It is useful when there is strong interference from anadjacent frequency. Since the main transceiver andsub-receiver share the same antenna for the 144MHz and 430/ 440 MHz bands, activating theattenuator function for the sub-receiver also causesthe function to switch ON for the same band of themain transceiver.PRE-AMPLIFIERThe pre-amplifier amplifies the level of receivedsignals. It is useful when the receiving signal is weak.If there is no strong interference from adjacentfrequencies, switch the pre-amplifier ON to raise thereceiving signal level. Since the main transceiver andsub-receiver share the same antenna for the 144 MHzand 430/ 440 MHz bands, activating the pre-amplifierfunction for the sub-receiver also causes the functionto switch ON for the same band of the maintransceiver.DUAL WATCHIf different frequency bands are set on the maintransceiver and sub-receiver, you can still monitor theother band activities while transmitting on the TXband. It is useful that you can still monitor the localrepeater frequency (VHF or UHF band) while you areworking on a DX station on the HF band of the maintransceiver.If you have the same frequency band (VHF or UHFband) for the main transceiver and sub-receiver, youcan monitor both frequencies independently at thesame time. However, both receivers will temporarilymute when you transmit because the transceivershares the same 144 MHz and 430/ 440 MHz bandantenna between the main transceiver and sub-receiver.SCANAll types of scanning are also available for the sub-receiver. However, the operating frequency range islimited to the sub-receiver’s frequency coverage.Refer to “SCAN” {page 66} for details on how tooperate the scan function.NOISE REDUCTIONSince the sub-receiver can receive only in FM or AMmode, DSP noise reduction 1 (Line Enhanced) isavailable to reduce the noise from the receivingsignals. Refer to “NOISE REDUCTION” {page 56} fordetails on how to control and adjust the function.TRANSMITTINGFirst, confirm that the “ ” icon is on the SUB banddisplay. Press [SEND] or press and hold Mic [PTT],then speak into the microphone in your normal toneof voice. When you finish speaking, press [SEND]again or release Mic [PTT].SELECTING A TRANSMIT POWERYou can also adjust the output power for FM mode onthe 144 MHz and 430/ 440 MHz bands when you areoperating the sub-receiver.1 Press [PWR].• The current transmit power appears.2 Turn the MULTI/ CH control counterclockwise toreduce the power or clockwise to increase thepower.Note:uThe selectable range varies depending on the band and mode{page 79}.uOutput power configuration is also reflected in the maintransceiver.MICROPHONE GAINAccess Menu No. 41 and select “LOW”, “MID”, or“HIGH” for the microphone gain.Note: When using the optional MC-90 microphone in FM mode,select “HIGH” microphone gain. Microphone sensitivity is low in FMmode; this may cause insufficient modulation. For othermicrophones, select “MID” or “LOW”.FM REPEATER OPERATIONYou can also configure an independent repeateroffset frequency for the sub-receiver, if necessary.Refer to “FM REPEATER OPERATION” {page 32} fordetails.REVERSE FUNCTIONPress [TF-SET] to switch the sub-receiver Reversefunction ON (or OFF). “R” appears while the Reversefunction is active on the sub-receiver. Refer to“REVERSE FUNCTION” {page 34} for details.
