7. Troubleshooting:
Please refer to the following table for possible trouble if the indicator light for PWR is
steadily on or you cannot dial any number after the power supply is on.
Number Binary Code
ST0 ST1 ST2
Designation
0 000 〇〇〇 No signal
1 001 〇〇● Network registration
failed
2 010 〇●〇 PIN needed
3 011 〇●● PUK needed
4 100 ●〇〇 No valid SIM card
5 101 ●〇● Operator locking failed
6 110 ●●〇 Terminal locking failed
If you may find and deal with the error according to the above table, do it by yourself.
You may restart the terminal for checking of any improvement. If you cannot deal with the
error, please turn to the distributor or the operator.
7.1 Troubleshooting telephone set:
The telephone set linked to the terminal should be DTMF (dual-tone multi-frequency)
phone. If both T (for DTMF) Mode and P (for DC Pulse) Mode are available, make sure
your phone set is always switched to T Mode when connected with the terminal. After
connecting the phone to the terminal, pick up the handset and see if the PHONE indicator
light glows or not. If it glows, the connection is all right. If it blinks, check the connection.
After checking if the PHONE indicator light still blinks, there is error in the telephone set.
Use a new phone set and see if it works. If still no working, turn to the distributor or the
operator.
7.2 Troubleshooting power supply:
The POWER indicator light shows the working conditions of the power supply. If
POWER light is off, the AC power is not available or the voltage is lower than the working
level.
7.3 Troubleshooting antenna:
If the voice is not clear or intermittent and no error found in the telephone set, turn to the
antenna for possible cause.
See if POWER indicator light is blinking.
If no GSM signal strength indicator lights are on, check the antenna:
See if the antenna is damaged or not;
GSM FIXED WIRELESS TERMINAL 11 USER MANUAL

See if the connection between the antenna and the terminal is tight or not;
See if the antenna is placed in a vertically upright position and if the antenna is far away
from any barrier.
※The antenna should be as far away from the telephone line and power supply line. Do
not wind the antenna line with the telephone line as this may cause GSM
electronic-magnetic wave interference in power supply and telephone line.
