Charging the battery
When the weight display shows “
lb1
”, the battery voltage is low in voltage and
should be recharged. Connect the main power cord to the outlet. The charging
process will start while the scale is powered on or not.
When the battery is getting close to the low battery, the annunciator
(PRECAUTION AGAINST LOW BATTERY) will come on. Prepare to charge the
battery.
The scale can be used while the battery is charging. After fully charged, the scale
will change the charging process to trickle charge automatically.
The battery cannot be charged with the OP-04 in operation. Turn the power off to
charge.
Charge the battery at a temperature between 0°C (32°F) and 40°C (104°F).
Preferably 5°C (41°F) ~ 35°C (95°F) is recommended.
Charge the battery when using for the first time.
The battery must be recharged regularly if the scale is not used for a long
period of time. Every 3 months in a warmer area and every 6 months in a
cooler area will be needed.
