Charging Status Indicator (For the inbuilt MB-70 12V rechargeable batteries): A

flashing red light indicates charging is in progress while a steady red light indicates that the

batteries are fully charged. However, if the indicator remains flashing after normal charging

hours, it means the inbuilt rechargeable batteries are damaged and both damaged inbuilt

batteries must be replaced immediately.

AC Input Socket: A built-in switch mode power supply allows for AC power inputs ranging

from 100V to 240V.

Battery Cover: There are two battery covers, one for each rechargeable battery. In the

event that you ever have to change a battery, please observe the correct polarity and always

keep the battery full-charged. Unless you experience some battery failure, changing or

uninstalling batteries should not be necessary. If in doubt, please contact your nearest service

agent or supplier.

Wheels: Heavy duty and a truly user friendly feature.
