6.1 Battery selection
To avoid leakage and poor autonomy, it is highly recommended that only good quality, new and identical
alkaline batteries be put into the UNO. Good quality rechargeable batteries can also be used with the
UNO and recharged with an external charger.
The batteries n eed to be replaced if the UNO displays “LO” on its digital display or if it does not power-up
when the I/O control key is pressed.
6.2 Battery installation
- Put the UNO face down on a flat surface.
- Lift the kickstand.
- Open and remove the battery door.
- Insert one battery in the nylon strap (to ease removal) and insert it at one extremity of the UNO battery
compartment with the right polarity. To avoid intermittent contact and involuntary disconnection, firmly
insert the batteries. Insert the other batteries over the nylon strap with the right polarity so that pulling on
the strap will pull every battery out of the UNO.
- Put the battery door back in place.
6.3 Battery removal
- Put the UNO face down on a flat surface.
- Lift the kickstand.
- Open and remove the battery door.
- Hold down the UNO and slowly pull on the nylon strap to remove the batteries. Do not use a pointed
tool to remove the batteries, since that could puncture them. The batteries need a firm pull to be removed
in order to have a reliable contact.
