When humidity levels reach the dew point, condensation occurs and damage to
CR3000 electronics can result. Effective humidity control is the responsibility of
the user. The CR3000 module is protected by a packet of silica gel desiccant,
which is installed at the factory. This packet is replaced whenever the CR3000 is
repaired at Campbell Scientific. The module should not normally be opened
except to replace the internal lithium battery.
Adequate desiccant should be placed in the instrumentation enclosure to provide
added protection.

Your new CR3000 is already configured to communicate with Campbell
Scientific datalogger support software
(p. 90)
on the RS-232 port, and over most
comms links. If you find that an older CR3000 no longer communicates with
these simple links, update the operating system and do a full reset of the unit, as
described in Resetting the CR3000
(p. 454).
Some applications, especially those
implementing TCP/IP features, may require changes to factory defaults.
Configuring modifies the firmware of the CR3000. Programming modifies the
CR3000 CRBasic program. Settings are key to configuring the CR3000.
