bage but must be disposed of in a responsible way. Follow the regulations from the environ-
mentally responsible local authorities which are valid at the time of disposal. As a rule, the
same procedure may be used which are applied for the disposal of car batteries, because the
EC II GSM SE battery is designed in a similar way.
The EC II GSM SE may not be used if the battery is not mounted and connected, but the bat-
tery can be replaced during operation. If battery is replaced during operation the battery alarm
can be activated but the reset button S1 can reset the battery alarm. If the battery is mounted
with reverse polarity the equipment will not be damaged but a battery alarm will be activated.
After battery replacement it is recommended that the reset button S1 on the printed circuit
board of the central unit is used. It will recharge the new battery completely and test it.
The battery can operate the equipment for at least 60 minutes as long as the current con-
sumption for various connected external units does not exceed the specifications.

7.2 Battery charging
The built-in battery charger checks that the battery is continuously charged and an empty bat-
tery is fully charged in a maximum of 14 hours. The battery charger is temperature compen-
sated and has a limitation of current charging to prevent damages if an empty battery is
mounted.
7.3 Battery test
The capacity of the battery is tested automatically every 30
th
day and the test can last up to 90
minutes depending on the condition of the battery. The better the battery the shorter the test
will be. If the battery voltage by the battery test sinks below a certain level a battery alarm
goes out. The first battery test is made after 17 hours of operation.
