Balances with the optional rechargeable battery will need to be charged for 12 hours before the
balance can be operated on battery power for the first time. The battery is protected from
overcharging so the balance can remain connected to the AC power. When the battery is fully
charged the battery indicator on the display will stop blinking.
To remove the rechargeable battery option and install C cell batteries, reference the Recharging
Battery Option instruction manual for step by step instructions as well as disposal instructions.
CAUTION: Risk of explosion can occur if the rechargeable battery is replaced with
the wrong type or if it is not properly connected.
Note:
After power on, it is recommended to warm up the balance for at least 5 minutes before using it.
