Connect Adaptor and Charging
To charge the battery, insert the adaptor pin to jack. Adaptor simply plugs
into the main power. The scale does not need to be turned on.
The battery should be charged for 12 hours for full capacity.
Left to the count display is an LED to indicate the status of battery charging.
When the scale is plugged into the mains power, the internal battery will
be recharged. If the LED is green, the battery is fully charged. If it is red,
the battery is running low on battery and if yellow, the battery is being
charged.
Do not use any other type of power adaptor than the one supplied with the
scale.
Verify that the AC power socket outlet is properly protected.
Note: Please charge the battery before using the scale for the first time
.
