carrier's agent be present when opening the carton. Save the carton packing material for
future use.
After unpacking the system, inspect it thoroughly for hidden damage and loose
components or fittings. If the contents are incomplete, if there is mechanical damage or
defect, or if the system does not work properly, notify your dealer.

• Provide space enough to access the front panel connectors and for installing a cradle for
the speaking device.
• Provide at least 120 mm space at the back of the SAILOR 7222 VHF DSC radio to
allow free air circulation and for cable access.

SAILOR GMDSS Console or on a bulkhead using the screw kit included in the delivery.
