*The compression ratio depends on the redundancy of data items. The more redundant the
data, the higher the compression ratio will be.
**The observation length is defined to be the amount of time the chamber is closed
collecting data.
Using a Wireless Card
An optional wireless package (p/n 8100-565) is available from LI-COR for those
users who want to control the LI-8100A via a wireless network. The wireless
package includes a fixed networking Type II PC Card that can be inserted into
either of the two PC card slots in the Analyzer Control Unit. The wireless PC card
will replace either the Ethernet adapter card or Compact Flash card. The wireless
card included is the only card warranted for use with the LI-8100A; while other
cards could be used, LI-COR cannot guarantee the integrity of the data. Separate
instructions for wireless networking with a PDA are included with the LI-8100A;

Wireless Communication".
Air Filters
There are two Balston air filters located inside the Analyzer Control Unit. One of
the filters is on the flow path from the attached chamber, and the other is on the
bellows air path, and is used only when a Survey Chamber is attached. The
bellows air path draws air from outside of the Analyzer Control Unit through a port
on the front panel.
The air filter on the flow path will need to be replaced after about 3 months of
continuous use, depending upon the conditions under which the instrument is
