Operation

Please read all the warning notices at the front of this manual before applying

power to the AIS Transponder and setting the equipment to work.

Activation

It is recommended that AIS should not normally be powered down and should

always remain in operation continuously. However, based on the Master’s

professional judgement, either transmissions may be inhibited by selecting

‘Silent mode’ or the AIS may be powered down entirely if continuous operation

might compromise the ship’s safety or security. This might be necessary in

waters where pirates or armed robbers are known to operate or during some

cargo handling or maintenance operations.

Actions of this nature should always be recorded in the ship’s logbook.

Reactivation of the AIS should take place as soon as the reason for deactivation

has passed.

Compliance

The M-2 AIS complies with international standards and is type approved in

accordance with the European Marine Equipment Directive. The EU Declaration

of Conformity, shown on the rear pages, lists the relevant approval standards .

Details of other Worldwide type approvals are listed on the McMurdo website
