Intrinsic safety marine radio adopts a new optimized intrinsic safety design. The battery adopts dual output current limiting protection and short circuit protection. The whole structure design is compact and reliable,with safe and reliable intrinsic safety performance, and is the ideal professional communication transceiver in hazardous gas working environment.



Compliance with EU intrinsically safe certification standards

Passed the EU ATEX II 2G Ex ib IIB T4 intrinsically safe explosion-proof certification, in line with the SOLAS regulations for ship firefighters communication

 

Digital intercom / analog intercom dual use

Can be used as a digital radio or as an analog radio

 

UHF band

UHF (400-470MHz), strong signal penetration

 

Hidden LED screen display

Can display volume, power, channel, signal strength, squelch level time, etc.

 

Read and write frequency is fully encrypted User data is safer

 

One-button SOS emergency alarm

An emergency call can seek help from peers or the control center in case of emergency

 

Group call function

When this feature is enabled, each radio has its own independent frequency (channel) that can receive calls from other members of the group, regardless of which channel they are communicating on.

 

 

IP56 waterproof and dustproof

Waterproof and dustproof design, which increases the service life of the machine and can be used normally under various harsh environments.
