VHF
If your AMX has the optional VHF, it will turn on based on the depth or the status of the burn wire. If the
depth is deeper than 1.0 m, the VHF will turn off. The VHF will be turned on and stay on after the burn
wire is triggered.
Depth Sensors and Maximum Depth
The OpenTag3 is equipped with one of two types of pressure sensors, each of which has a maximum depth
that it can sustain. If the tag could go deeper than 300 m, the air void where the microSD card is located
should be filled with mineral oil. Mineral oil is non-conductive, and will keep the cap from imploding if the
tag goes deeper than 300 m.
