OVERVIEW

1. OVERVIEW
Reliable GMDSS (Global Maritime Distress and Safety System) communication requires improved
technology through automation and digital electronics. SRG-4 MF/HF Radio Equipment, designed and
developed for medium and long range communications, fully satisfies all the requirements of GMDSS. The
SRG-4 consists of a MF/HF transmitter, a Digital Selective Call (DSC), a Narrow Band Direct Printing
(NBDP) device, a MF/HF receiver and the DSC watchkeeping receiver. These units are used to
communicate digital data and is ideal for automatic processing in distress safety communications as well as
ordinary communications. Maintenance and inspections is made simple through the self-diagnostic functions
and by modularization of the respective units.
1.1 Features
(1) Total control
In order to satisfy the requirements of GMDSS and improve ordinary communications, it is impossible
to avoid increasing the complexity of the equipment while adopting the conventional method of
combining desk-mounted instruments for simple operations.
The SRG-4 is set up with the major modules combined as one unit or circuits within a single
cabinet. Thus, it is possible to rationalize the total control system by interlinking the respective module
controls.
(2) Operability
All general operations such as communications, controls and monitoring, are performed by using the
printer and the compact type controller (including the data terminal) which is installed in a convenient
place. DSC and NBDP operations such as communications, editing messages and viewing received
messages are performed by using the controller. Distress calls can be sent and received by one-touch
operations in an emergency.
(3) Configurability
The system cabinet (main unit) and the antenna tuner (which can be installed near the antenna) are
controlled by MF/HF controller. Therefore, a large area is not required for operation.
(4) Miscellaneous
* Switch to the auxiliary power supply (batteries), can be on/off to supply power of the outside
equipment in case of using such as a VHF radio and INMARSAT equipment.
* An auxiliary power supply (battery) charger is provided.
* More than one controller can be installed. (option)
* Can be operated FULL DUPLEX Radio.

c) Wait until the green LED on the front panel of the DSC watchkeeping is on
d) Press the [PWR] key on the front panel
3.2 Operating on AC power
When AC power is supplied to the main unit, the SRG-4 works automatically on AC power.
Although the [PWR] key is not pressed, DSC and watchkeeping receiver works.
DSC watchkeeping scanning frequency is indicated by six LEDs on the MF/HF control panel.
In this mode, if a DSC distress or DSC alarm call is received, the [DISTRESS] or [OTHERS] LEDs on
MF/HF control panel will light up and the alarm tone is sounded.
(Refer to 6.13 for the operating instructions if a DSC distress or DSC alarm call is received.)
3.3 Operating on DC power (Battery)
When AC power is disconnected, the SRG-4 automatically switches to the DC operation and the [DC]
LED on MF/HF control panel will light up. When transmitting by NBDP or DSC, or transmitting a
distress alert signal, it automatically selects high/low power mode. In this case, it is not necessary to press
[TX] key. when press the MF/HF key, be selected MF/HF equipment, outside equipment(VHF or

charged, a low current is supplied to maintain the rated battery voltage. The charge mode indicator
between automatic and normal is by the charge switch on the system cabinet.
∙
Auto mode - When the battery is low, automatically charge. The default is auto mode.
∙
Normal mode - Regardless of battery status, charge the battery.
