Compliant to new FCC Class D DSC Regulations
- Escalating DSC Alarm
- An on/off switch for the radio to automatically switch to
channel 16 when a DSC call is made
- 2 receivers, one for the radio and one to monitor channel 70
for DSC full time
Superior receiver performance
The IC-M604A has excellent receive
specifications*
which allow a weak signal a better chance of being heard when
louder signals are around it. The powerful 5.0W (typical) audio
output from the front facing speaker further increases the
audibility and quality of received calls.
* More than 80dB for intermodulation
rejection and adjacent channel selectivity, and 0.22μV (typical)
high sensitivity.
Large LCD with dot-matrix characters
The large full dot-matrix display is designed for optimum
readability in any lighting condition. With the extra large
font, the channel number is maximized on the display and upper
and lower case characters can be easily read.
30 Watt 2-way hailer capability
When connected to an external hailer horn, communication with
other boats, deck or dock hands is easy. The built-in 30W
amplifier increases your talk power making your message loud and
clear. Four foghorn patterns are also available.
Submersible construction
(1m depth for 30 minutes)
The IC-M604A, including the supplied microphone, withstands
submersion in up to 1.0m depth of water for 30 minutes. It is
equivalent to IPX7 waterproofing.*
* except cables
Built-in ITU Class-D DSC
No matter what channel you're tuned to, a separate and
independent receiver inside the M604A continuously monitors Ch.
70. The 10-keypad allows simple and efficient operation of the
DSC emergency functions, vital for your safety at sea.
Position request and position report
Over and above the DSC, your own and other ships´ position data
can be exchanged with the position request or position report
functions. The received position information can be transferred
to external GPS or navigation equipment*.
In addition, the polling (request/ reply) function checks
whether a specific ship is within the communications range.
* NMEA 0183 format is required.
Improved GPS information indication
When connecting to an
external GPS receiver, the GPS information indication function
shows course and speed data as well as position, date and time
on the display.
Front and rear
panel microphone connection
The speaker microphone can be detached from the front panel and
can be connected to the rear panel without any modification. An
optional 6.1m (20ft) microphone extension cable, OPC-1000, is
available.
RX speaker function
The RX speaker function, receiver-repeater allows you to monitor
the received radio audio from a hailer horn on the deck or
tower. You can also make an announcement on-board from the
microphone.
Favorite channel function
This function allows quicker channel selection. Set the “TAG”
channel to the channels used most often. When pushing the
up/down buttons on the speaker microphone, only tagged channels
are selected and untagged channels are skipped. The “TAG”
scanning function detects only tagged channels.
