PANEL DESCRIPTION
!1 KEYPAD
Enters the selected channel number (or fre-
quency*) for direct channel selection. (p. 7)
Stores a receive frequency into a user chan-
nel or ITU simplex channel when:
pushing [CE] (s appears)
entering the desired frequency via the keypad
pushing and holding [RX] (p. 12)
Adjusts the RF gain after pushing [FUNC] to
reduce the receiver sensitivity. (p. 10)
Stores a transmit frequency into a user chan-
nel (except General versions) when:
pushing [TX] ($ ashes)
pushing [CE] (s appears)
entering the desired frequency via the keypad
pushing and holding [TX] (p. 12)
Selects the transmitter channel for cross
channel operation (Europe versions only)
when:
pushing [TX] ($ ashes)
entering the desired channel number via the key-
pad
Selects the transmit output power after push-
ing [FUNC]. (p. 9)
Toggles the channel number input and fre-
quency input.* (p. 8)
•“s appears when frequency input* is selected.
The channel selector and keypad changes the
frequency while s appears.
Clears the entered digit and retrieves the pre-
vious channel (or frequency*) while entering
numbers. (p. 7)
Enters the name programming condition,
after pushing [FUNC], for changing the chan-
nel name. (p. 12)
Toggles the channel and frequency indica-
tions. (p. 6)
Enters “–” for ITU simplex channels. (p. 7)
Enter channel number with up to 4 or 5 digits
when s does not appear. (p. 7)
Enter the frequency with up to 6 digits* when
“” appears. (p. 8)
!2 SQUELCH SWITCH [SQL] (p. 10)
Activates the voice squelch function to reject un-
desired background noise while no signal is
being received.
The squelch opens only when the received signal
contains no 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] (p. 9)
Selects an operating mode temporarily. Available
modes differ with 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 OVEN INDICATOR (GMDSS version only)
Internal high-stability crystal oscillator unit contains
a temperature-compensating oven heater. This
high-stability crystal oscillator improves frequency
stability.
•“STANDBY appears when power to the main unit is
turned off.
!7 TRANSMIT FREQUENCY SWITCH [TX FREQ]
(p. 9)
Displays the transmit frequency and opens the
squelch to check and monitor the transmit fre-
quency.
!8 2182 kHz SELECTION SWITCH
[2182kHz
RESET
] (p. iii)
Selects channel 0 (2182 kHz; distress call fre-
quency).
The channel selector does not function when select-
ing channel 0.
Ignores external control and gives the front panel
control priority when an external controller
(NMEA format) is connected.
!9 ALARM SWITCH [ALARM] (p. iii)
Emits a distress alarm signal from the speaker.
Transmits a distress alarm or alarm testing signal
when pushed together with the [TX FREQ]
switch.
NOTE: General versions are not equipped with this
[ALARM] switch.
*Some versions do not have frequency selection and fre-
quency indication.
