Notes:
• If the battery is completely discharged when the phone is placed in the charging unit,
there will be no display initially until the battery has reached a certain charge level. This
may take several minutes and does not mean there is a malfunction.
• Even when the phone is switched off, the battery will still slowly discharge.
• When the battery capacity is almost exhausted, a series of warning beeps sounds. This
warning can be disabled, see chapter
, page
. If you
are making a call, you have approximately five minutes' talk time left before the handset
switches itself off.
• The state of charge is also available via the service menu: Press key 5 and hold it down
for a moment.
• Information on operating times can be found in the chapter "Battery charge and usage
