6. Troubleshooting
Use the following section to diagnose and remedy various common fault
conditions.
6.1. Phone not responding to 1234stat0 request via SMS:
•
With handset removed from cradle is there a dial tone indicating the unit
is ready to make a call or pulsing dial tone indicating no network
connectivity?
•
With the faceplate removed check if any of the internal indicator lights
are illuminated, if not, lift handset from cradle, do indicator lights come
on? If yes see Indicator functions under section 4.9 and the various
FUNCTION and ERROR Light scenarios below;
•
Check the unit is switched on by pressing the On/Off button, see section
4.10.
•
If still no Indicator Lights on, check the unit is connected to an external
DC power source. If necessary check the input voltage is in the range 9V
to 18V.
•
If it is known no external DC power source is connected check the
internal battery is physically connected and if necessary check the
terminal voltage coming from the battery pack is greater than 3.75V. If
the voltage is below this value the unit could be in auto-shut off mode
and the internal battery will need to be charged. Connect the external DC
power source and allow the battery to charge for a minimum of 30
minutes, full charge will take in excess of 5 hours.
•
If there is no voltage present across the internal battery terminals check if
the in line battery fuse has been blown? If the fuse has blown, check the
internal battery leads have been connected with the correct polarity, if not
remedy and replace the in line battery fuse assembly. NOTE: This
assembly is a safety component and MUST ONLY be replaced with the
correct in line fuse assembly from GAI-Tronics.
6.2. ERROR light is permanently ON
•
Check the SIM card has been installed and has been installed correctly,
see section 4.5.
6.3. ERROR light flashing Long/Fast
•
This indicates the SIM card is locked and a PIN code is required to
unlock it. The PIN code can only be entered via the USB connection
using the command: AT+CPIN
