    Using buttons : buttons have the main and secondary function activated by [F] press. Alphanumeric buttons are used like those of a mobile telephone to type characters. Button [ENT] is used to accept a selection.
    Button [CE] is used to cancel commands or return to previous menu level.
    Knobs are rotated by dragging mouse cursor around their centres.
    Distress button is covered by a flap, which opens automatically with a click on the button.
    Function How to implement

    channel selection The transceiver has 160 programmable user channels and ITU channels. All channels are divided into groups, user channels making up 8 groups of 20 channels in each plus groups for ITU channels. ITU channel groups are for 4MHz (2 groups for duplex and simplex channels), 8MHz (2 groups), 6 MHz (2 groups) and so on, for 8Mhz, 12Mhz, 16Mhz, for 18Mhz, 22MHz and 25 MHz.
    A channel can be selected in two ways : using the knobs and the keypad. The GRP knob is used to select a channel group, the CH knob - to select a channel within a group.
    The second way is channel selection by keyboard : type in channel number by alphanumeric keys and press ENT. The user-programmable channels has only digits (1..160), so just type in numeric keys; to select a simplex ITU channel, a string like 4-3 (4MHz group, channel 3) should be entered. To enter dash, hit button [0 DIM] 3 times, so hit [4] [0] [0] [0] [3] [ENT] in succession.
    The currently active radio channel is shown on the display in two ways : as a channel number or as frequency. To switch between these two modes, press [FREQ/CH].
    setting programmed channels channels from 1 to 160 are programmed. To program a channel, select its number by using GRP and CH knobs or by typing its number on the keypad. The diplay shows empty frequency field if has not been set already. Press [CLAR/RX]. Type RX frequency value using numeric keypad. Press AND HOLD(!) [ENT] button. Press [TXF/TX] to set TX frequency. If the field is empty, type a frequency value using the keypad. If it is not, use CH knob to select a digit position and then press a digit button to change the digit.
    When entering a frequency value, change emission type, if needed, using [MODE/SET] button.
    Do not forget to press and hold [ENT] to save the value. If just press [ENT], the frequency will be adjusted temporarily, but not saved!
    tune the receiver diplay shows blinking "TUNE" sign if the transceiver is not tuned. Press [TUNE].
    transmitting stop all scans, set a channel and press the PTT (Push-To-Talk) button on the microphone. Hold down the button while you speak. To be heard from another ship equipped with another MF/HF radio, the receiving radio must hold the receiving (RX) radio frequency equal to transmitting (TX) frequency of the transmitting radio. Specifically, it means that the communication is OK when the two parties communicate on the same SIMPLEX (equal TX and RX frequencies) channel.
    Communications between ships are not possible on duplex channels, which have different RX and TX frequencies.
    Only ship-to-coast commincations are possible on duplex channels, as a coast radio swaps RX and TX channel frequencies.
    The transceiver should be tuned to be able to transmit (press [TUNE]).
    tune the receiver diplay shows blinking "TUNE" sign if the receiver is not tuned. Press [TUNE].
    setting squelch level [SQL] button is used to switch squelch function on and off to suppress interference noise. Press [F] and then [SQL]. Note that during a scan the noise may lock a channel, so squelch should be off when scanning
    channel scan frequencies for scan are taken from a whole channel group. Select a group by GRP knob, switch squelch off (display should not show the SQL sign) by [F] and [SQL]. Press [F] and [SCAN] to start scanning frequencies of the selected group. To stop the scan, press [F] and [SCAN] again. Any rotation of [GRP] or [CH] knobs also stops the scan. Scan type is selected in initial set mode.
    programmed scan programmed scan scans frequency range from channel 159 to channel 160. Switch squelch off (display should not show the SQL sign) by [F] and [SQL]. Press [F] and [SCAN] to start scanning. To stop the scan, press [F] and [SCAN] again. Any rotation of [GRP] or [CH] knobs also stops the scan.
    Scan type is selected in initial set mode.
    scan type selection scan type selection is NOT CURRENTLY AVAILABLE, channel scan is the default mode.
    switch between radio and DSC watch mode press [DSC].
