BASIC OPERATION 5 ■ Setting squelch level The squelch circuit mutes the received audio signal depending 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 select the squelch level. • "LEVEL 1" is loose squelch (for weak signals) and "LEVEL 9" is tight squelch (for strong signals). • "AUTO" indicates automatic level adjustment by a noise pulse counting system. • "OPEN" indicates continuously open setting.

The transceiver has total 5 operating modes (A 3 band: FM, WFM and AM modes, B band FM, FM-N, AM and DV modes). The mode selection is stored independently for 4 each band and memory channel. 5 Typically, AM mode is used for the AM broadcast stations 6 (0.495-1.620 MHz) and air band (118-136.995 MHz), and WFM is used for FM broadcast stations (76-107.9 MHz). 7 WFM mode cannot be selected above 810 MHz for U.S.A. version. 8 ➥ Push and hold [MODE](REC) for 1 sec. several times to 9 select the desired operating mode. 10 • While pushing and holding [MODE](REC) , rotate [DIAL] is also available to select operating mode . 11 • Display example 12 FM 13 A 1 4 5 0 0 025 14 PSKIP FM mode 15 WFM A 1 4 5 0 0 025 16 WFM mode PSKIP 17 REC MODE AM A 1 4 5 0 0 025 18 PSKIP 19 AM mode 21
