Installing The Battery; Installing The Back Cover - BenQ M580 User Manual

Installing the Battery

With the battery's metal contacts facing downwards, align the
protruding tabs on the end with the holes in the battery bay. Then push
the battery toward the end of the bay to insert the battery's tabs into the
holes. Press down to click the battery into place.
Do not remove the battery when the phone is on. Doing so could
cause you to lose personal settings or data stored either on your SIM
card or in the phone's memory.
