72PANEL DESCRIPTION2q RECEIVE INDICATOR“RX” appears when signals are received or thesquelch is open.w TUNE INDICATOR“TUNE” blinks while tuning, if an optional externalantenna tuner is connected. (p. 10)• “TUNE” appears after tuning is completed with AT-141.• “THRU” appears when the tuner through function is ac-tivated.• “SWR” appears when the antenna SWR worsens duringtransmit, depending on the transmit output power. If itappears, check your antenna system.e OPERATING MODE INDICATORShows the selected operating mode.• “J3E,” “USB,” “H3E,” “AM,” “LSB,” “J2B,” “AFS,”“F1B,” “FSK,” “A1A” or “CW” appears depending onoperating mode and setting.r SIMPLEX/DUPLEX INDICATOR“SIMP” appears when a simplex channel is se-lected.“DUP” appears when a duplex channel is selected.t FUNCTION INDICATOR“ ” appears when a secondary function can be ac-cessed.y CLARITY INDICATOR (p. 12)“CLAR” appears when the clarity function is acti-vated and shows shifting frequency in “Hz.”u SPEAKER OFF INDICATOR (p. 10)“ ” appears when the speaker output is turnedOFF.i AGC OFF INDICATOR (p. 11)“ ” appears when the AGC OFF function isturned ON.o POSITION/UTC TIME INDICATOR (p. 15)Shows position and/or UTC (or local) time. Whenan NMEA0183 ver. 3.01 data is applied to [GPS],the indication is up dated automatically.• When no NMEA data is applied, the position and UTCtime must be set in advance.• “GPS” appears when an NMEA0183 ver. 3.01 data isapplied to [GPS], “MNL” appears when the position ismanually set.• “UTC” appears when the offset time has not been pro-grammed. (No “UTC” indication when offset time is pro-grammed and shows local time.)!0 CHANNEL NUMBER INDICATIONShows the selected channel number.!1 S/ANTENNA CURRENT INDICATORShows relative driving antenna current levels dur-ing transmit and receiving signal strength during re-ceive.!2 NOISE BLANKER INDICATOR (p. 11)“NB” appears when the noise blanker function is ac-tivated.!3 SQUELCH INDICATOR (p. 11)“SQL” appears when the squelch is ON.!4 TRANSMIT INDICATOR➥ “TX” appears during transmit.➥ “TX” blinks while monitoring a transmit frequency.(p. 10)!5 CHANNEL NAME/RECEIVE FREQUENCYREADOUT➥ Shows the programmed channel names.➥ Shows receive frequency when no channel nameis programmed, or during frequency indication.➥ During DSC watch mode, displays “DSC WATCH.”!6 TRANSMIT FREQUENCY READOUTShows transmit frequency.!7 OPERATING GUIDE INDICATIONDuring DSC watch mode operation, shows severaltypes of guidance, according to the selected condi-tion.!8 SCANNING FREQUENCY READOUTDuring DSC watch mode operation, shows the pro-grammed scan frequency.• Decimal points blink.!9 MMSI CODE INDICATIONDuring DSC watch mode operation, shows the pro-grammed MMSI code.y IF FILTER WIDTH INDICATORShows the selected IF filter passband width duringe-mail operation mode.A G CS P
