MODEL 346 INSTALLATION AND OPERATION MANUAL
2.1 UNPACKING
The recorder is shipped in a special pack, designed to ensure adequate protection during transit. Should the
outer box show signs of abnormal wear or damage, it should be opened immediately and the recorder examined.
If there is evidence of damage, the instrument must not be operated, and the local representative should be
contacted for instructions.
After removing the recorder from its packing, the packing should be examined before it is discarded to ensure that
all accessories and documentation have been removed.
2.1.1 CHASSIS REMOVAL
Open the door of the recorder.
Depress the latch at the lower right corner of the chart cas-
sette (figure 2.1.1a). Pull the cassette up and out until it
disengages from the recorder chassis.
Locate the chassis jacking bolt shown in figure
2.1.1b and release the recorder chassis from the
case by rotating the bolt anti-clockwise. This also
has the effect of disconnecting all rear terminal
board connections (including power) to the recorder
chassis
Note...
If the recorder has been installed, it should be iso-
lated from mains (line) power, before it is removed
from the case.
