connect the battery, see section "Installation" on page 116.
Note: Place the phone in the charger and charge it for at
least one hour before using it the first time.

soap or any other cleaning materials may discolor or damage the
phone. Clean the battery contacts using ethanol or isopropyl
alcohol.
