Insert the Battery
Your device is provided with a lithium-ion battery and is designed to be used exclusively
with original NGM batteries and chargers. The battery must be inserted into the backside
of the phone. Insert the battery into the battery compartment with its contacts facing
those of the phone. Then, put on the back cover by first inserting it on the bottom of the
phone and then pressing it on the top to adjust it on the upper part of the phone. To
remove the cover, use the slit in the lower right part of the phone, remove the top part
first and then the bottom part, as shown below.
