Further explanation of the LED functionality is described below:
RED LED
(Power
Indicator)
When the unit is powered on using main power, the LED will be permanently on.
When the main power is cut, the unit will switch to backup battery mode, the
LEDwillashuntilthebackupbatteryrunsoutofpower.
Troubleshooting: Check that you have a valid 12V or 24V source connected to
the device. The Red wire should be connected to the positive terminal, and
the Black wire should be connected to the Ground terminal. If there is power
applied to these wires, please check the power supply by using a Voltmeter
across Red and Black wires of the device. If there is 12V supplied but the device
is still not powering up, please disconnect both wires, then leave the device
unplugged for 5 minutes, then reconnect. This process will reset the internal fuse
on the device.
YELLOW LED
(GSM/GPRS
Indicator)
TheyellowLEDwillashwhenthedeviceisconnectedtothetrackingserver
with a valid GPRS connection. It will stay on continually when it is in sms mode
only, or when the GSM is present but there is no connection to the server.
Troubleshooting: If the yellow light is not on at all, please ensure the GSM
antenna is connected, and that the sim card is properly inserted, with the gold
terminals facing the circuit board. Please ensure the terminals are clean, and
the sim card clips into place appropriately. If this fails, please put the sim card
into a phone, and make sure that it is registered, and that you are able to send
a message from the phone. Please ensure the sim pin on the sim card has been
disabled (this can be done in the security settings in a mobile phone). If the
yellowlightison,butnotashing,pleaseensurethatyouhavethecorrectAPN,
username and password set for the network. The APN is usually different for each
network provider, and can be found by calling the telecommunications provider,
some telecommunications providers require a username and password to be
declared, please ensure that you have these details. The APN, username and
passwordcanbesetonlyfromtheprimarydenedphonenumber(pleaserefer
to the Users Manual for setting primary identity). The primary phone needs to
send commands for setting the APN, username and password (these commands
can be found in the command list in the users manual) If the LED comes on
solid, and stays on solid for a period of about 1~ 2 minutes, then turns off for
30 seconds, before turning on again, this means that the device has weak GSM
signal, and it is trying to acquire GPRS. Please take the vehicle outdoors and
check the GSM reception on any phone using the same service provider.
If the problem persists, please try a different GSM antenna.
GREEN LED
(GPS
Indicator)
ThisLEDwillstayonwhenthereisavalidGPSx.WhenthereisnoGPSsignal,
or the device is unable to get clear view of the sky, the LED will be off.
Troubleshooting: Please ensure that the GPS antenna (gold connector) is
connected to the gold antenna connection, and that it is mounted in a suitable
spot with clear view of the sky. The vehicle must be outside to be able to get
aGPSx.
