WARNING/SAFETY INFORMATION

 

  The GX750 is a radio transmitting device.

 

   When transmitting, keep any part of your head or body more than 20 cm from  

the antenna.

 

  Do not transmit near electrical blasting equipment or in explosive atmospheres.

 

  Do not allow children to operate a radio transmitter unsupervised.

OPERATOR QUALIFICATIONS

Any person in Australia operating a VHF marine radio should possess at least a Short Range 
Radio Operators Certificate of Proficiency (SROCP). Alternatively, operators may obtain a Long 
Range Radio Operators Certificate of Proficiency (LROCP), which covers the operation of both 
VHF and MF/HF equipment.

Many TAFEs and marine organisations offer courses leading to examination for the SROCP and 
LROCP although such courses are not compulsory. Persons wishing to obtain the SROCP or 
LROCP should first purchase a copy of the Maritime Radio Operator Handbook which is essential 
reading for every boat owner in Australia.

The Australian Maritime College (AMC) provides the marine examination and certificate service 
on behalf of the Australian Communications and Media Authority (ACMA). The AMC can 
provide the details of organisations and individuals offering courses and or conducting exams.
