The SMS Lite
has an LED, labelled ‘Link’ situated next to the aerial connection. The
LED will indicate various events that have occurred:
▪
When it powers on it will toggle on and off 5 times slowly.
▪
While it is has connected to the network it will indicate 1 short pulse every two
seconds.
▪
Each time it sends an SMS OK it will indicate a burst of 5 short pulses.
▪
If it tried to send an SMS but there was a problem it will indicate 3 long pulses.
The SMS-Lite may indicate and error code that can be used to identify the following
issues:
▪
2 pulses indicate that the Modem won't power on.
▪
3 pulses indicate that the Modem won't respond to commands.
▪
4 pulses indicate that the SIM card is not inserted.
▪
5 pulses indicate that the SMS-Lite is not registered to the cellular network.
▪
6 pulses means the cellular operator is not supported by the device
(contact
QTech).
▪
7 pulses indicate that the SIM card is currently busy. This can occur briefly during
the initialisation phase after it is powered on.
Errors 2 and 3 require the SMS-Lite be returned to QTech for service.
Error 4 may be fixed by checking the SIM card inside the SMS-Lite.
Error 5 is normally caused by a weak signal to the cell tower.
Error 6 may occur in some overseas locations.
Error 7 may occur if the SIM card is not compatible with the SMS-Lite.
There is one other type of error indication, and that is when the SMS-Lite tries to send a
message but gets an error code back from the phone network, it will blink 3 times
slowly. If the message was sent successfully it will blink 5 times quickly. The normal
reason for an error is that there is no credit on the SIM card, but could also be
something like the cell tower being busy.
