Battery Replacement
It is highly recommended that the battery be replaced every 12 months, or prior to logging critical data.
The TH10 does not lose its stored readings when the battery weakens or when the battery is replaced; the data
logging process will however be stopped and cannot be re-started until the battery has been replaced and the
logged data has been downloaded to PC.
Use only 3.6V lithium batteries. Before replacing the battery, remove the datalogger from the PC. Follow
diagrammatic steps 1 through 4 below.
NOTE: Leaving the RHT10 plugged into the PC USB port longer than necessary will cause some of the battery
capacity to be lost.

WARNING: Handle lithium batteries carefully, observe warnings on battery casing. Dispose of in accordance
with local regulations.
