Floating Radio

The orange center makes it visible and easy to retrieve. This rugged radio is also designed to meet JIS7 (IPX7) specifications. This means it’s designed to operate properly after being submerged in one meter deep water for 30 minutes.


Very little maintenance is required to keep your Cobra Marine VHF radio in good operating condition:

  •  Keep the radio and charger clean by wiping with a soft cloth and mild detergent.Do not use solvents or harsh or abrasive cleaners, which could damage the case or scratch the LCD screen.
  • If the radio is exposed to salt water, wipe with a soft, moist cloth at least once a day to prevent buildup of salt deposits, which could interfere with button operation.
  •  This is especially important if you are using alkaline batteries.

VHF Marine Radio Procedures 

Maintain Your Watch

Whenever your boat is underway, the radio must be turned On and be tuned to Channel 16 except when being used for messages.


If there is no answer,switch to 3 watts and call again. You have the ability to go up to 6 watts of output power to increase your calling distance. Remember, the lower wattage outputs will conserve your battery and minimize interference to other users.

Calling Coast Stations

Call a coast station on its assigned channel. You may use Channel 16 when youdo not know the assigned channel.

Calling Other Vessels

Call other vessels on Channel 16 or on Channel 9.  You may also call on ship-to-ship channels when you know that the vessel is listening on a ship-to-ship channel.
