The AIS SART should be tested annually to confirm correct operation. In order to maximise the available battery capacity it is not recommended to test the AIS SART more frequently. Carry out the following steps to test the AIS SART:

1. Remove the AIS SART from the bracket or bag and move to an outdoor location with a clear view of the sky. Do not hold the AIS SART in the location marked over the internal GPS antenna.

2. Press and hold the ‘Test’ button for three seconds until the indicator starts flashing. The test is now active and the AIS SART will attempt to obtain a GPS position fix for five minutes.

3. The outcome of the test is indicated as shown in Figure 11. During the test AIS messages are transmitted and will be received by all nearby vessels. Refer to section 4.5 for further information on display of AIS SART position and messages on other equipment.

4. If a pass is not indicated by the end of the test period then the AIS SART should be relocated and the test repeated.
5. If battery expiry is indicated please contact your dealer to arrange for battery replacement. Section 5 provides further details on battery replacement.

The AIS SART test can be cancelled at any time by pressing and holding the ‘Test’ button for three seconds. The indicator will extinguish when the test has been cancelled.
