Putting into service
After connection of the external power supply the device will fi rst check the SIM
card. If no card has been installed, or if it is broken or cann't be recognized by
the unit, the red LED will start to fl ash quickly. In this case the SIM card has to be
changed.
If everything is OK the device will start the initialisation procedure and login to the
provider. This can take some time about 30 to 60 seconds. During this time the red
LED will fl ash quickly. After succesful login the red LED will fl ash slowly.
PIN code
For normal use we suggest to use SIM cards without PIN code. In this case deactiva-
te the PIN code for the specifi c SIM card using a mobile phone before you install it
into the GSM500.GC. If required also the following PIN code handling can be used.
Program using a mobile phone the PIN code to "0000" on the SIM card you are going
to use. Install now the SIM card into the GSM500.GC.
The device will now reprogram the PIN code automatically with a random generated
code and overwrite the old one, locking this way the SIM card with the device.

Battery
The bulid in NiMH battery is continously tested by the GSM500.GC. If it will dein-
stalled or fail the device will rise an appropiate alarm. A battery error is also showed
by the blue LED. Furhermore this status is also indicated by a special dial tone. Every
30 seconds the device will check if the battery is connected or not. Also the batte-
ry capacity is tested by a discharging procedure. The fi rst time this procedure will
take place 15 days after fi rst activation. During the procedure the battery will be
discharged over a load for 3 hours. If after the test the battery capacity will be below
a defi ned level an appropiate alarm is rised. The discharging test will not take place
or will be interrupted if the device is missing the external power supply. Furthermore
the battery is protected against deep discharge. The battery should be changed any-
way all 2 to 4 years depending on the installation enviroment and usage. In case of
substitution only the same or a equivalent battery must be used to avoid damage on
the product. The remaining capacity which should be recognized by the device after
a discharging procedure is programmable. As default this value is 4 hour emergency
power stand by time. This value can be changed in eight steps between 1 and 7
hours.
PLEASE NOTE!
The battery capacity can vary a lot depending from the working temperature.
If the GSM500.GC is going to be installed in location where temperature below
-5° C the threshold value should be reduced to avoid unnecessary battery
alarms.
