■ Open the battery lid located in back of the scale and turn main switch off.
■ Separate the battery connector and take out the discharged battery.
■ Put a charged battery in rear and connect the battery connector.
Turn main power switch on and cover the battery lid.
■The drop of battery voltage can affect the brightness of display.
To prevent this, the regular battery recharging is recommended.
■In case the battery will be left without recharging for a long time,
it is desirable the main power switch is set off.
Otherwise, it also can affect the battery life.
