215BASIC OPERATION12345678910111213141516171819 Setting squelch levelThe squelch circuit mutes the received audio signal depend-ing on the signal strength. The receiver has 9 squelch levels,a continuously open setting and an automatic squelch setting.➥ While pushing and holding [SQL], rotate [DIAL] to selectthe squelch level.• “LEVEL 1” is loose squelch (for weak signals) and “LEVEL 9” istight squelch (for strong signals).• “AUTO” indicates automatic level adjustment by a noise pulsecounting system.• “OPEN” indicates continuously open setting. Operating mode selectionOperating modes are determined by the modulation of theradio signals. The transceiver has total 5 operating modes (Aband: FM, WFM and AM modes, B band FM, FM-N, AM andDV modes). The mode selection is stored independently foreach band and memory channel.Typically, AM mode is used for the AM broadcast stations(0.495–1.620 MHz) and air band (118–136.995 MHz), andWFM is used for FM broadcast stations (76–107.9 MHz).➥ Push and hold [MODE](REC) for 1 sec. several times toselect the desired operating mode.AFMFM145 00025AWFMWFM176 00025AAMAM118 00025FM modeWFM modeAM mode• Display exampleAMemoNameMemoNameμPRIOPRIO WXWX EMREMRDTCSDTCSFMFMLOWLOWATTATT145 000P SKIP+DUP+DUP25000000SQUELCH:LEVEL9μ 000000P SKIPSQUELCH:AUTOμ 000000P SKIPAutomatic squelchMaximum level[DIAL]
