1.1 UNPACKING THE RECORDER
The recorder is despatched in a special pack designed to give adequate protection during transit. Should the outer box
show signs of damage, it should be opened immediately and the recorder examined. If there is evidence of damage,
the instrument should not be operated and the local representative contacted for instructions. After the recorder has
been removed from its packing, the packing should be examined to ensure that all accessories and documentation
have been removed. Once the recorder has been installed, any internal packing should be removed, and stored with
the external packing against future transport requirements.
