BATTERY REPLACEMENT
WARNING: Handle lithium batteries carefully, observe warnings on battery casing.
Dispose of in accordance with local regulations.
We recommend that you replace the battery every 12 months, or prior to logging critical data.
The EL-USB-4 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.
Only use 3.6V 1/2AA lithium batteries. Check with your supplier that the battery you are ordering is 'press fit' and
is not fitted with solder tags. Before replacing the battery, remove the EL-USB-4 from the PC.
Note:
Leaving the EL-USB-4 plugged into the USB port for longer than necessary will cause some of the battery capacity
to be lost.
