GSM LED (5):
This LED shows the current GSM status. For this, the LED has the following presentation options:
• LED is lit green = Searching for GSM network
• LED flashes green (every 1 s) = Device registered at the GSM network
• LED flashes green (every 1/2 s) = call / phone connection
• LED flashes red/green = no GSM network connection / PIN error / invalid SIM card / PUK / …
• LED off = no power supply present / product off
When the product is charged via the USB socket without any SIM card inserted, the green LED is displayed. Since this LED is
controlled right by the GSM module and the GSM module was switched off entirely (switch in the SIM card holder), this LED may be
lit by accident. Without SIM card, the GSM module is definitely off and will not try to log on to the GSM network.
Battery LED (4):
The internal battery is charged and managed via a separate hardware. Thus, the battery can also be charged when no SIM card is inserted and
the entire GSM hardware is deactivated. This LED provides the following information:
• LED is lit red: The battery is being charged
• LED is lit green: The battery is charged completely
• LED is lit orange (red and green at once): An error was recognised (e.g. no battery present)
• LED off = no USB voltage present
GPS status LED (1):
This LED is used to recognise the activity and status of the GPS receiver. The following display options are available for this:
• LED flashes blue: Current GPS position determined correctly
• LED is lit blue: GPS position not determined or determinable
• LED off: GPS module is in sleeper mode / switched off
The GPS receiver is on the front, right below the GPS-LED.
Important note on accuracy of GPS positions:
Accuracy of the GPS position determined depends on many factors. Since the GX103+GPS leaves the GPS receiver off at all times
for runtime reasons in battery-powered operation, this will negatively influence accuracy. The GPS signal as such is overlaid by
correction data that are saved in the device and will accelerate, among others, satellite search. Therefore, we recommend that the
product is left to assess the GPS positions for a few minutes if there are any problems with accuracy. This procedure is called
“tracking”. It should reduce the deviation to regular GPS accuracy. For this, observe the description on the command “TRACK”
LEDs in the buttons “1”, “2” and “3” (8/9/10):
These LEDs have various functions. The primary task is showing the current status behind the function that was linked to the corresponding
button.
If, e.g., the motion detection was configured behind button “1” (“MOVE”), pushing this button will activate the alarm sensor with its last settings
(can be recognised by the activated LED). Another push of the button will switch off this function and therefore the LED again.
Since the buttons have different functions in the “CALL” mode, the function described above only applies in regular mode (in which the alarm is
deactivated).
