Channel selection

Press F1. The printer responds by printing:
'ITU Coast station / interShip channel (C/S)?:
After pressing 'C' or 'S' as desired the channel number is requested and must be typed in.
The validity of the channel number is checked.
If the channel number does not exist this is indicated. If the channel number exists the
corresponding frequency pair is printed and the transceiver is set accordingly.
The radiotelex distress and safety frequencies may be selected by simultaneously pressing
'Ctrl' and the appropriate function key F1 to F6.
6.2.5 Transmitting a message
Before calling, it must be ensured that the transmission will not interfere with transmissions
already in progress. Switch the loudspeaker on and listen on the selected channel.
Press Call FEC or Call ARQ as desired and enter the call code of the station to be called.
For communication between two stations the ARQ mode should be used. FEC is used to
broadcast a message.
Before any message can be sent, wait until the connection has been established, or in the
case of FEC until the opening phase sequence has been transmitted. When the system is
ready for message transmission a ">" is printed and the Tx keyboard indicator shines steady
light.
After a successful ARQ connection has been established, answerback codes may be
exchanged by pressing the WRU and DE keys. A message may now be transmitted by
pressing carriage return (¬Enter) followed by the message to be transmitted, either typed in
directly from the keyboard, or recalled from the text memory by pressing the Send Message
key. Communication with coast stations must be in accordance with the procedures specified
by the particular coast station. Where the appropriate facilities are provided by the coast
station, traffic may be exchanged with the land telex network. Having completed the trans-
mission, an exchange of answer-back codes should take place. The radio connection is
terminated by pressing the Break key.
6.2.6 Editing a message
A text memory is used for storing a message for later transmission. The message can be
transmitted one or more times. The message is printed out when the Send Message key is
pressed in standby mode.
A message can be entered into the text memory after pressing the Edit Message key in
standby mode. Any previous contents of the text memory are printed out then it may be
supplemented, corrected or deleted. The maximum size of a message is 4000 characters.
