VHF MARINE TRANSCEIVER

Meets GMDSS requirements
The IC-GM651 is a compact VHF radio telephone with Ch 70
watchkeeping receiver and CLASS A DSC functions. The
radio meets the GMDSS requirements as required for SOLAS
regulated commercial vessels engaging in international voy-
ages. With the optional PS-250 DC-DC power supply, the
IC-GM651 also meets MED 96/98/EC, “wheelmark” require-
ments for European merchant ships.
Built-in ITU Class A DSC
An independent DSC receiver constantly watches Ch 70 VHF
DSC channel, while using another channel. The Class A DSC
provides automated distress and safety communication. Re-
ceived distress signals can be relayed to a coast station. Atotal
of 100 MMSI IDs can be stored with a 10-character name.
PS-250 DC-DC power supply and
PS-240 AC-DC power supply available
The optional PS-250* DC-DC power supply offers stable
12.5V power to the IC-GM651 from a 12V/24V DC (10.8–31.2V
DC) power source and provides floating ground connection.
The optional PS-240 AC-DC power supply unit is also avail-
able with the PS-250. When connecting a storage battery to
the PS-240, the PS-240 automatically switches the power
source for backup, even if the AC power fails.
* The PS-250 MUST BE USED with the IC-GM651 for MED certification
compliance.
HS-98 Handset and/or HM-126RB-1
speaker-microphone selectable
The IC-GM651 gives you the choice of a handset and/or
speaker-microphone. The handset provides clear audio even
in noisy environments. The speaker-microphone has a re-
mote control function to control operating channel and trans-
mit power with dedicated buttons.
Rugged and waterproof construction*
for professional use
To withstand harsh marine environments, the IC-GM651 has
been tested to and passed the rigorous salt spray test. In ad-
dition, the front panel of the IC-GM651 has waterproof pro-
tection equivalent to IPX7 which withstands 1m depth of
water for up to 30 minutes.
* The front panel of the IC-GM651 only.

Large full dot-matrix display
The large full dot-matrix display provides an easy-to-see user
friendly graphical interface. DSC operations can be made eas-
ily with the operation guide on the bottom line of the display
such as “ENT” to Set (OK), “CLR” to Go
back (BACK), “F8” to Print (PRT), etc.
The message icon ( ) on the display
shows you have a new DSC message.
Superior receiver performance
The IC-GM651 has excellent receive performance which al-
lows a weak signal a better chance of being heard when
louder signals are around it. The powerful audio output from
the front facing large 66mm diameter speaker further in-
creases the audibility and quality of received calls.
Slim dimensions for clean installation
The 109.4 mm* depth and 4×8” stylish design is easy to in-
stall into a limited space. Flush mount installation is available
with the MB-75 flush mount kit.
(* Projections are not included.)
