Unique features
●
Available as semi-duplex or full-duplex, this class A VHF 
  radiotelephone incorporates advanced modular design 
 that allows for maximum installation flexibility.

When connecting your AIS to the new VHF, new possibilities 
become available. This innovative feature, unique to JRC, allows 
you with one push of the button, to quickly navigate through a list 
of targets in your surrounding area. Bearing, range and MMSI 
information of target vessels are sorted from the shortest range 
upwards. You can now easily select the vessel you wish to get in 
contact with, and send a DSC message immediately.
Intercom and loudhailer
The VHF radiotelephone has an intercom functionality for easy 
communication with multiple other VHF controllers onboard! 
Additionally, to always be in full control and on top of 
communication with deck or dock hands, a loudhailer function is 
built in. An optional external speaker with amplifier increases talk 
power, making your messaging loud and clear, thereby adding to 
the safety of the vessel.
Clear display
Improved visibility is realised by the integrated 3.8" high 
brightness silver LCD screen with excellent sunlight viewability. 
The main data is displayed in large characters for easy reading.
Extendable up to 5 controllers
The VHF series configuration allows having up to 5 controllers 
covering various important sections onboard. Additionally, there 
is a range of possibilities for connecting extra handsets and 
printers.
120 seconds digital recording
JRC has included a recording function for the last 
120 seconds of open squelch (voice). 
In situations where loud engines or other background 
noises disrupt your reception, this characteristic 
feature enables you to immediately repeat any 
unclear messages.

Wing controller
Easy configuration
The JHS-770S/780D is developed upon maximum flexibility, having a separate 
transceiver and controller allowing flexible installation in confined spaces. Either 
panel, desktop or overhead mounting is possible with this size reduced VHF 
radiotelephone.
Easy operation
The combination of push buttons and JOG dial operation, together with JRC's innovative 
software including easy menu structures ensures logical, accurate and convenient operation.
For wing and/or outside applications, JRC has developed an optional, simplified 
channel selector. This compact weatherproof unit allows basic operation, such as 
channel and power selection, and has a channel 16 preset.
