!2 SQUELCH SWITCH [SQL] (p. 10)
➥ Activates the voice squelch function to reject
undesired background noise while no signal is
being received.
• The squelch opens only when the received
signal contains voice or FSK components.
➥ Starts and stops the scan function after pushing
[FUNC]. (p. 7)
!3 NOISE BLANKER SWITCH [NB] (p. 10)
Turns the noise blanker function ON to remove
pulse-type noise such as engine ignition noise.
• "NB" appears when the function is turned ON.
!4 AGC OFF SWITCH [AGC] (p. 10)
Deactivates the AGC function to receive weak sig-
nals blocked by strong adjacent signals.
• "ê" appears when the [AGC] switch is turned
ON (stands for AGC deactivated).
!5 MODE SWITCH [MODE]
Temporarily selects an operating mode. Available
modes differ with the transceiver version.
• J3E (USB), H3E, J2B (AFSK), FSK, R3E, and
A1A (CW) modes are available.
• The temporary mode is cleared and the previous
mode appears when changing a channel.
!6 TRANSMIT FREQUENCY SWITCH [TX FREQ]
(p. 9)
Displays the transmit frequency and opens the
squelch to check and monitor the transmit fre-
quency.
!7 2182 kHz SELECTION SWITCH
[2182KHz • ] (p. 6)
reset
➥ Selects channel 0 (2182 kHz; distress call fre-
