Procedure
1 Make sure that the Wide Band Transceiver (WBT) is installed in the correct location,
and that it is suitably oriented for easy maintenance and replacement of parts.
2 Make sure that the physical installation of the unit has been completed.
a Make sure that the compartment ("sonar room") is provided with ample
ventilation to prevent system units from overheating.
b Make sure that the compartment ("sonar room") is clean and dry.
c Make sure that the bulkhead structure to which the Wide Band Transceiver
(WBT) is fastened is substantial enough to hold the unit securely under all
operating conditions.
d Make sure that ample ventilation is provided to avoid overheating.
e Make sure that you have free access to all the connectors on the Wide Band
Transceiver (WBT) for maintenance purposes.
f Make sure that the bolts, screws or studs that have been used are all of the
correct size.
g Make sure that the correct flat and shake-proof washers have been used.
h Make sure that all the nuts have been tightened properly.

3 Make sure that the unit is not physically damaged, and that the surfaces and
paint-work are clean without dents or scratches.
The physical handling during the installation may have caused some minor
scratches to the surfaces or paint-work. This can be accepted. However, if rough
handling has caused serious damage, this must be recorded with a written statement
and necessary photos, so that corrective actions can be made.

a Make sure that the unit is securely connected to the ship's ground with an
earthing strap. The strap must be in addition to any incidental electrical contact
made by the mounting lugs on the unit.

ship's ground is approximately 0 (zero) Ω.
5 Make sure that cable installation has been completed.
a Make sure that all cables leading to and from the unit have been properly
mounted and secured.
