6.5.2.1 KIRK 3040/KIRK 4020/KIRK 4040 and KIRK 4080 Handsets
When charging the battery for the first time, it is necessary to leave the handset in the
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
and 77°F. Do not place the handset in direct sunlight. The battery has a built-in heat
sensor which will stop charging if the battery temperature is too high.
If the handset is turned off when placed in charger, only the LED indicates the
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.
If the handset is turned on when charging, the display shows the charging status. It
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.
The handset LED gives the following indication:
• LED continuously on - handset is fully charged
• LED flashing - handset is charging
