3.4 I/O Cable Overview
Always remove the retaining strap on the end-cap underwater-connect cable
and dummy plug when disconnecting them. Failure to do so will break
the retainer strap.
Do not apply any upward force on the end-cap connector as the I/O cable is
being disconnected. Stressing the end-cap connector may cause the
ADCP to flood. Read the Maintenance guide for details on disconnecting
the I/O cable.
