11 NBDP TRANSMITTING, RECEIVING
11-11
11.9.2 Preparations
To use automatic telex, you will need to register three items:
• Answerback code
• Scan groups
• Station names
Registering answerback code
The coast station assigns a Telex number. This number functions as an answerback code.
An answerback code contains the following:
OOOOO SHIP X
OOOOO: Coast station-assigned five-digit telex code
SHIP: Ship name
X: For shipboard station, normally X is entered.
The procedure for registering the answerback code is the same as which appears on page
9-1. If an answerback code was registered before the commissioning of the coast station,
a new answerback code must be entered. To enter a new answerback code, contact
FURUNO or an authorized FURUNO agent or dealer.
Registering scan groups
The central system emits a free-signal to indicate a coast station radio channel is in idle
condition and available for ship-to-shore calls. The free-signal is detected and recognized
by the shipboard equipment as a permission to start the transmission. Then, the shipboard
operator initiates a call.
You can scan search for the free-signal automatically by registering coast station radio
channels in scan group(s). The procedure for registering scan groups for coast station use
is the same as that which appears on page 9-7.
Registering stations
The next step is to enter station name. The procedure is the same as that shown on page
9-3.
