Battery installation & charging
Install the battery as shown on the next page. Once you have installed the
battery, the screen indicates the battery status (see table below). If necessary,
place the handset in the telephone base to charge the battery. For best
performance, keep the handset in the telephone base when not in use. The
battery is fully charged after 6 hours of continuous charging. See the table
on the
Technical specification page of the user’s manual for battery
operating times.
If the screen is blank, you need to charge the handset without interruption for
at least 0 minutes to give the handset enough charge to use the telephone
for a short time. The screen shows
LOW BATTERY and the backlight is off
until you have charged the battery without interruption for at least one hour.
The following table summarizes the battery charge indicators and actions
to take.
