BATTERY REPLACEMENT
We recommend that you replace the battery every 1 month, or prior to logging critical data. The EL-USB-LITE does not lose its
stored readings when the battery is discharged 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.
For maximum logging life, only use Maxell or Panasonic CR1620 lithium batteries. Before replacing the battery, remove the EL-
USB-LITE from the PC.
Note:
Leaving the EL-USB-LITE plugged into the USB port for longer than necessary will cause some of the battery capacity to be lost.
WARNING: Handle lithium batteries carefully.
Dispose of in accordance with local regulations.
