The Radio Check reassures us that the VHF is working properly and is therefore a function of undeniable value at the level of safety.
It is strongly suggested to carry out the Radio Check before every sea trip, in order to avoid surprises when we will have to use the VHF.
If we are technical installers, we can use this function instead of other sophisticated tools.
The function shows the voltage of the batteries in transmission, the RF transmission power and detects the correct functioning of the antenna.
