3 Channel Master Care
This section contains a list of items you should be aware of every time you
handle, use, or deploy your Channel Master. Please refer to this list often.
3.1 General Handling Guidelines
• Never set the Channel Master on a hard or rough surface.
The urethane faces may be damaged.
• Always remove the retaining strap on the end-cap underwa-
ter-connect cable and dummy plug when disconnecting them.
Failure to do so will break the retainer strap.
• Disconnect the I/O cable by pulling it off in a straight in-line
motion. Stressing the end-cap connector may cause the
Channel Master to flood.
• Do not expose the transducer faces to prolonged sunlight.
The urethane faces may develop cracks. Cover the trans-
ducer faces on the Channel Master if it will be exposed to
sunlight.
• Do not expose the I/O connector to prolonged sunlight. The
plastic may become brittle. Cover the connector on the
Channel Master if it will be exposed to sunlight.
• Do not store the Channel Master in temperatures over 75
degrees C. The urethane faces may be damaged. Check
the temperature indicator inside the shipping case. It changes
color if the temperature limit is exceeded.
• Do not scratch or damage the O-ring surfaces or grooves. If
scratches or damage exists, they may provide a leakage
path and cause the Channel Master to flood. Do not risk a
deployment with damaged O-ring surfaces.
• Do not lift or support a Channel Master by the external I/O
cable. The connector or cable will break.
3.2 Assembly Guidelines
• Read the Maintenance section for details on Channel Master
re-assembly. Make sure the housing assembly O-rings stay
in their groove when you re-assemble the Channel Master.
Tighten the hardware as specified. Loose, missing, stripped
hardware, or damaged O-rings can lead to water ingress
and damage to the Channel Master.
