Caution

Maintenenca work on the done only by trained and
qualified personnel at a company approved service center
within the warranty period. For locations of Fluke Service
Centers worldwide and contact information, see the Fluke
website:

www.fluke.com

.

With the proper use, the Logger does not require special maintenance other
than periodic calibration at a Fluke calibration center.

If the Logger gets dirty, wipe it off carefully with a damp cloth without
cleaning agents.

Lithium Battery

The 1745 Logger contains a vanadium pentoxide lithium rechargeable battery
and a sealed gel-type, lead-acid battery. These batteries are automatically
recharged during normal operation. Neither one is user-servicable.

Disposal

If you discard the Logger, you must recycle it at an appropriate recycling
center as required by local regulations.
