charger for 14 - 16 hours before the battery is fully charged and the handset ready for use.
Warning: Do not charge 4080 Handset in a potentially explosive atmosphere. Use only the
dedicated charger (orange) for charging of a 4080 Handset.
Note: During normal operation, it takes approximately 3 1/2 hours to charge the handset
from fully discharged to its full capacity.
• Place the handset in the charger.
For correct charging, be sure the room temperature is between 0°C and 25°C/32°F

sensor which will stop charging if the battery temperature is too high.

charging. When handset is turned off, the LED flashes at a low frequency while
charging and lights constantly when the charging is finished. There will be no
reaction for incoming calls.

will not vibrate. B-answer is inactive. The handset reacts normally for incoming calls.
The display goes back to normal mode when fully charged.
It is necessary to recharge the battery when the display shows BATTERY LOW, or if the
handset cannot be turned on. When the battery is fully discharged, up to 10 minutes may
pass before charging begins (display lights up). When the charger begins the charging,
status is shown on the display if the handset is turned on.
The handset displays a progress indicator bar that shows how fully charged the battery
is.

• LED continuously on - handset is fully charged
• LED flashing - handset is charging
