Except for Distress and Urgency calls, all communications shall be made on a sector working frequency. 4.6.2 Test transmissions Test transmissions shall include the name or call sign of the centre and shall be limited to 10 seconds or less. 4.6.3 VHF channel interference Attempt to identify the source when communication interference occurs. As the controlling station, resolve the situation by having one or all interfering stations cease transmission on the Port Control channel and either stand-by or move to another frequency. 4.6.4 Interruptions Normally a transmission that is in progress has priority over new calls; however, distress, urgency or safety communication to transmit shall be entitled to interrupt any transmission in progress that is of a lower priority. Any transmission may be made to effect the interruption followed immediately by the appropriate signal. Date: 18.08.2008 Page: 4-2 Doc: VTS Manual
