VHF Marine - Restricted Operator's Certificate (MARITIME) - ROC(M)

.VHF - Marine ROC(M) with DSC Endorsement - Maritime Radio Is a must for boaters who want to operate a radio. In Canada anyone who uses a VHF radio is required by law to be certified in order to use a VHF or other marine radio transmitter. VHF Operators must follow the procedures described in the VHF Radiotelephone Practices and Procedures Regulations. Currently, all Marine VHF radio operators are required to have a Restricted Operator's Certificate (ROC) with maritime qualifications issued by an accredited agency under the authority of Industry Canada - Spectrum Management, a department of the Government of Canada.

The VHF radio is your lifeline in an emergency or distress situation and certain protocol must be followed.

In order to obtain a Restricted Operator Certificate (Maritime) one must successfully complete a VHF - Restricted Operator's Certificate Maritime ROC(M) course including the new Global Maritime Distress Safety System (GMDSS), Digital Selective Calling (DSC) Endorsement with the Maritime Mobile Service Identity (MMSI) System. Our CPS/Industry Canada Recognized instructor/Examiner will provide instruction. Successful completion of this course certifies you for VHF Maritime, MF and SSB Radio.

The DVD that accompanies this course includes a simulator allowing practice using DSC on your home PC or computer as well as practice questions for each chapter and practice exams. It can be played in a CD player to learn the protocol for the Verbal Radio portion and assists with preparation for the exam.
