1.3 Turning the Power On/Off
The power switch is combined with the [VOLUME] control. Turn the [VOLUME] control
clockwise until you hear a click. Further clockwise rotation of the control raises the loudspeaker
volume. To turn off the power , turn the control fully counterclockwise until you hear the click.
1.4 Adjusting the Backlighting
The [ /9] key adjusts the backlighting for the operation display and the keyboard. Each time
the key is pressed, the backlighting changes in the sequence of high, medium, low and off.
1.5 Turning the Loudspeaker On/Off
When you are using a handset and therefore do not require the internal or external loudspeaker,
you can turn it off by pressing the loudspeaker [ /4] key. The “loudspeaker off mark” ( )
appears.
1.6 Turning the Squelch On/Off
The squelch mutes the audio output in the absence of an incoming signal. Each time [SQL/5] is
pressed, the squelch is turned on or off. When radio noise is too jarring during stand-by condition, it may be muted by activating the squelch. “SQ” appears when the squelch function is
active.
Note: The squelch is disabled on the class of emission TLX or FAX; “SQ” blinks.
1.7 Selecting Class of Emission, Turning AGC On/Off
Selecting class of emission
The [MODE/1] key selects the class of emission. Each time the key is pressed, the class of
emission changes in the sequence of LSB, J3E, H3E, TLX (J2B) and FAX (F3C).
Indication Symbol Class of Emission
LSB* J3E Single Sideband radiotelephony(LSB)
J3E J3E Single Sideband radiotelephony(USB)
H3E H3E Equivalent to AM radiotelephony. Only at 2182 kHz for
transmitting, any frequency for receiving.
TLX* J2B Radio Telex
FAX* F3C Reception of weather facsimile broadcast
* Available with system setting by FURUNO authorized service agent.

T urning AGC on/off
AGC is automatically turned on when frequency is changed, and “AGC” appears when AGC is
active. To turn AGC on or off manually, press the [MODE/1] key while pressing and holding
down the [ENT] key.
1.8 Selecting Frequency
Frequency can be selected by:
• Direct key entry (Free selection within marine bands for ship stations
where a qualified Radio Operator is available.)
• Channel number entry
• [FREQ/CH] control
A receiving frequency can be selected by one of the above methods, but there is a restriction in
selecting a transmitting frequency . This depends on how the equipment is programmed according to the national radio regulation.
Frequencies are indicated by:
Voice frequencies: Designated by the CARRIER frequency. Assigned frequencies are 1.4 kHz
higher than the carrier frequencies.
Telex, DSC: Designated by the CENTER frequencies.

Do not forget to enter the last zero in the above example. The last numeral repr esents the 1/10
decimal place. Simply hitting [TX], [RX], [2], [1], [6], [1], [ENT] will set 216.1 kHz.
* Order of pressing may be reversed, that is, you may press [RX] first.
1-6
User channels
You can recall user channels through the keyboard by channel numbers. Once a channel is
selected with the keyboard, the channel can be changed with the [FREQ/CH] control.
For how to write user channels, see Chapter 3. 199 user channels ( 0-01 to 0-99 and 1-00 to 1-
99) can be programmed in addition to ITU channels.
To call the channel 1-20, for example:
Tx only
Press [TX], [CH], [1], [2], [0], [ENT]
RX only
Press [RX], [CH], [1], [2], [0], [ENT]
TX and RX paired
Press [CH], [1], [2], [0], [ENT]
Note: The standard sets provide readout of Rx CH No. and Rx frequency in kHz. When trans-
mitting, Tx CH and Tx freq. are displayed. Pressing the [ENT] key displays both Tx and Rx
frequencies.

This radiotelephone is furnished with J2B class of emission. The J2B is compatible with F1B
which may be used on other parties. You do not have to worry about F1B or J2B; you can just
select TELEX mode for narrow-band direct-printing.
Press [CH], [4], [0], [1], [2], [ENT], and a combination of TX frequency of 4178.0 kHz and

1.9 Displaying Station Name
User channels 0-01 to 0-65 can be registered with a name, and it or the Rx frequency can be
displayed on the second line of the display. This function is available when a system setting is
set to display both channel and frequency. See page 3-3 for how to register station name.
1. Press [ENT] and [CURS/2] keys together. Each time those keys are pressed together, Rx
frequency or station name is displayed on the second line of the display.

1.10 Transmitting
After selecting class of emission and frequency, you can transmit by pressing the PTT (pressto-talk) switch on the microphone (handset). (“T” appears when the PTT switch is pressed.
Output power can be evaluated on the operation display . Do not transmit any signal other than
emergency during the silence period, 00 to 03 min, and 30 to 33 min of every hour.
Tuning the antenna
Maximum transmission power is achieved only when the antenna impedance and transmitter
impedance match each other . Because the antenna impedance changes with frequency a means
must be provided to match (tune) the antenna impedance with the transmitter impedance. This
is done with the antenna coupler. The antenna coupler automatically tunes the transmitter to a
wide range of different antenna length (6 – 15 m). To initiate the automatic tuning, do the
following:
1. Press the PTT switch on the microphone (handset), or the [TUNE/7] key.
2. “TUNE” appears on the display.
3. Tuning will be completed within 2 to 15 seconds for a newly selected frequency, or less than
0.5 seconds for a once tuned frequency. (A built-in memory remembers coil and capacitor
settings.)
4. When the tuning process is successfully completed “OK” appears.

Using the microphone
Hold the microphone close to your mouth, press the PTT switch and speak clearly.

Reducing transmitter power
T o conserve energy and to minimize possible interference to other stations, reduce the transmission power . This should be done when using the transceiver in a harbor , near the shore or close to
communication partner (other ship). Each pressing of the [H/L /8] key selects high or low
output power. “LOW” appears on the display when low output power is selected. The output
power on 2182 kHz (distress and calling) is the rated maximum regardless of the position of the
[H/L /8] key.
1.11 Distress Call on 2182 kHz
The frequency 2182 kHz is an International radiotelephony distress, urgency and safety frequency for ship stations, public and private coast stations, and survival craft stations. It is also
used for call and reply by ship stations on a primary basis and by public coast stations on a
secondary basis.
Distress or emergency call is generally initiated by a radiotelephone alarm signal on 2182 kHz.
Watch keeping receivers on other parties will hear your call.
1. Press the [2182] key . 2182 kHz and the class of emission H3E is automatically selected (J3E
may be selected depending on system setting).
When the [2182] key is pressed, the following parameters are set automatically:
AGC: ON
Output power: Maximum
Loudspeaker: ON
Squelch: OFF

2. While pressing and holding down the [ALM] key, press
