Installing the Transmitter on a High Pressure Hose Extension

WARNING
Always use the pre-installed flow restrictor when using the transmitter directly attached to your regulator
(Installing the Transmitter on Your Tank Regulator, page 13). Always use the included air spool when connecting
the transmitter to a high pressure hose extension. Using the transmitter without either the flow restrictor or air
spool could result in serious injury or death from an air pressurization failure.
Before you install the transmitter on a high pressure hose extension certified to the EN 250:2014 standard, you
should read the transmitter position tips and choose a position that provides the best line of sight to the dive
computer.
