1.1 Annual Performance Test
1.1.1 General
Netwave Systems recommends performing an Annual Performance Test (APT) every 12 months
referring to MSC.1/Circ.1222.
The APT can only be performed by Netwave Systems certified agents. An overview of the global
service network of Netwave Systems can be found on
‘Service’. For assistance please contact our service department.
Please note that an APT is valid/completed only when a Certificate of Compliance is issued.
1.1.2 Replacement/maintenance beacon and batteries Core Module
The expiry date of the beacon and the reserve power source (4 batteries in the Core Module) will
b
e checked during the APT but please note that these can expire in between the APT’s.
Beacon
The battery of the beacon needs to be replaced every 3 years. A beacon needs to be replaced
every 6 years. Expiry date can be found on the label of the beacon or in the most recent APT
checklist.
Batteries Core Module
The 4 batteries in the Core Module need to be replaced every 2 years after installation. Expiry
date can be found on the ‘battery expiration date’ label (placed on the outside of the Core Module),
on the expiry label of each battery or in the most recent APT checklist.
1.2 Operational Performance Test
1.2.1 General
According to resolution MSC. 333(90) the Voyage Data Recorder needs to be able to perform a
performance test at any time, e.g. annually or following repair or maintenance work to the VDR or
any signal source providing data to the VDR. This test may be conducted using the Bridge Control
Unit and should ensure that all the required individual data items are being recorded correctly.
Netwave Systems highly recommends performing an Operational Performance Test (OPT)
monthly.
This test should be performed by using the Bridge Control Unit. The performance test will indicate
the status of all connected sensors.
To start the OPT, push ‘Menu’ on the opening screen. This screen provides the choice for the
OPT.
