7.0 BATTERY OPERATION
• The scales can be operated from the battery, if desired. The
battery life is approximately 50 hours.
• When the battery needs charging a symbol on the display will turn
on. The battery should be charged when the symbol is on. The
scale will still operate for about 20 minutes after which it will
automatically switch off to protect the battery.
• To charge the battery, simply attach the power supply module to
the scale and plug in. The scale does not need to be turned on.
• The battery should be charged for 12 hours for full capacity.
• Below the display is a LED to indicate the status of battery
charging. When the scale is plugged into the mains power the
internal battery will be charged. If the LED is green the battery is
being charged. If it is red it is nearly discharged and yellow
indicates the battery is increasing the charge level. Continue to
charge overnight for a complete re-charge.
