1.6 Indicator LED Flash Patterns
The instrument is equipped with a multi-colour indicator LED, located adjacent to the shackle.
The table below describes the pattern and colour indications.
1 - LGR instruments may be deployed without GPS lock. Data will be recorded but locaon informaon
will not be updated from the previous posion.
2 - The instrument may be deployed in any of these states. Data will be logged.
3 - 6000m variants of AML-6 and AML-3 LGR instruments do not have on-board GPS. Double-flash will
not occur.
4 - The instrument will show a solid white LED to signify the baery is full only when the instrument’s
power switch is in the off posion and the charging cable is installed between the instrument and a
power source.
1.7 Pressure Ratings
Pressure ratings may differ between installed sensors and the instrument body, and
deployments should never exceed the shallower of these ratings. For example, a 500m
instrument equipped with a 6000dBar pressure sensor is limited to deployments of 500m depth
or less. Similarly, a 6000m instrument equipped with a 500dBar pressure sensor is also limited
to deployments of 500m depth or less.
The instrument pressure rating is identified on the end of the instrument, adjacent to the
shackle. Typical ratings for AML-3 and AML-6 LGR instruments are 500m and 6000m (note that
the AML-3 LGR 500m instrument and both AML-6 LGR ratings use plastic housings, while the
AML-3 LGR 6000m instrument uses a titanium housing).
