7. BATTERY
•
The scales can be operated from the rechargeable battery, if desired.
The GBK/GFK scales have up to 70 hours battery life before needing to
be recharged if the backlight is disabled and the battery is fully charged.
•
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 a period of time after which it will automatically switch off
to protect the battery.
•
To charge the battery, simply plug into the mains power supply. The
scale does not need to be turned on.
•
The battery should be charged for 12 hours for full capacity.
•
To the right of 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.
8. BACKLIGHT
The backlight for the LCD can be set by the user to always off, always on or
automatic (on only when the scale is in use or a key is pressed). See setting of the

9. AUTO POWER OFF
The auto power off can be set by the user to disable the feature or to a pre-set time
interval. See setting of the parameter “S3 AoF “ in section 13.3.
