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.
