Reducing transmitter power
To conserve energy and to minimize possible interference to other stations, reduce the transmis‘
sion 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
[HIL I8] keyl
1.11 Distress Call on 2182 kHz
The frequency 2182 kHz is an International radiotelephony distress, urgency and safety fre—
quency 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 (1315
may be selected depending on system setting),
When the [2182] key is pressed, the following parameters are set automatically:

1.10 Transmitting
After selecting class of emission and frequency, you can transmit by pressing the FIT (press-
to— talk) switch on the microphone (handset). (“T" appears when the FIT 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 FIT 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 anewly 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.
1.12 Receiving
You can select a receiving frequency by one of the following methods:
- Direct frequency entry, or
- Channel number entry
Adiusting RF gain
In normal use the [RF GAIN] control should be set for maximum. If the audio on the received
channel is unclear or interfered with other signals, adjust (usually reduce) the control to im-
prove clarity.
Clarifier adiustment
If reception is unclear, try to clarify the signal as follows. For manual entry of frequency, sim-
ply tum the [FREQ/CH] control for fine tuning.
1. Press the [CLARl/3] key. (If a frequency is selected by CH No., the cursor which was
located at the channel number. moves under the 10 Hz place and “CLAR” appears on the
display.)
2. Turn the [FREQ/CH] control to fine tune the receiver on the wanted frequency.
3. To terminate this operation, press the [CLARI/S] key again. The cursor returns to the chan-
nel number.
S-meter
During reception, the meter works as a Sensitivity Meter indicating the relative signal strength
coming into the receiver front end. While in transmission, it indicates output level at the trans—
ceiver.
02468105
\l\\l|lllll/
Figure 1-11 S—meter
Note: S—meter will not work with AGC off.
Monitoring traffic on intended transmit frequency
When a semi—duplex (two-frequency simplex) channel is selected, it is recommended to moni-
tor it if there is no existing traffic on the frequency you are going to use. To do this, press the
[RX] key followed by the [ENT] key. The transceiver unit monitors traffic on the selected
frequency for three sec. If you want to monitor continuously, press the [TX] key followed by
the [ENT] key.
2. While pressing and holding down the [ALM] key, press
the [ENT] key. The alarm signal. modulated at 1300 Hz
and 2200 Hz tones alternately. is emitted at full power
for 45 sec.
The alarm can be monitored from the loudspeaker. The
alarm may be canceled at any time by pressing the [ENT]
key for immediate speech transmission.
3. Distress calls and Distress message
(1) Speak slowly and distinctly, “MAYDAY, MAY-
DAY. MAYDAY. pronounced as the French expres-
sion “m’aider”.
(2) This is;
(3) The name of your vessel and call sign three times.
Then, continue with the distress message, which con—
sists of:

Squelch is used to mute the receiver audio output when the receiver input is less than a preset
value or dominant noise is higher than a preset (1000 Hz) frequency. To switch the squelch
function ON, press the [SQL/S] key. Make sure the label “SQ” appears on the display To pick
up a weak signal at high audio frequencies, you should remove the squelch function notwith-
standing a possible increase of background noise. To do this, press the [SOL/5] key again.
Make sure the label “SQ" goes off.
Noise blanker (NB)
The noise blankcr clips inputs of noise resulting from an engine ignition or motor brush sparks,
It can be enabled or disabled through the system settings.
1.14 Frequency Sweep
Sweep is the function where the receiver searches for a signal within a selected frequency
coverage. AGC is automatically tumed on in frequency sweep.
The defaults of respective parameters are as follows:
Sweep stop signal level: 3
Sweep step time: 2 sec
Sweep width: 100 kHz
Step frequency: 1 kHz
These can be adjusted on system codes 9951 through 9954‘
Note: Sweep width is the frequency width to sweep on both sides of the selected frequency.
Sweep step is the frequency interval at which the receiver sweeps the sweep width.
Mrs
1. Select the sweep center by key operation.
2. Press the [SCAN/6] key. “SWEEP” appears and the receiver starts sweeping. To stop sweep-
ing, press the [SCAN/6] key.
ITU channels
To select the scan group (band or channel, including user channels), shift the cursor to either the
position of the band or channel number by pressing the [CURS/Z] key. (Band scan is useful to
watch frequencies on the same channel in different bands.)
2. Press the [SCAN/6] key, and “SCAN” appears. The receiver starts scanning‘ stopping at a
channel where the signal is stronger than the scamstop level. The receiver will restart scan-
ning when the traffic goes out of that channel or designated time elapses, depending on

Scan/sweep-stcp signal level
When the receiver detects a signal whose level is stronger than the preset
level it stops scanning and receives the signal. The setting on system code
9955 is available only when “0" (SQ working condition) is selected here.
Setting range: 0 (Squelch working condition is effective as set on code
9955), 1—10 (S-meter level); Factory setting: 3
Scan/sweep—stop time
When a signal is detected, the receiver stops scanning/sweeping and dwells
on this channel frequency. When “0” (RX) is selected, the receiver keeps
receiving until the traffic goes out of this channel frequency. Define the
dwell time between 1 and 99 sec.
Setting range: 0 (RX), 1—99 sec; Factory setting: 2
