3.1 Indicator Instructions
1) The power indicator (red) indicates whether the power get through or not. The indicator
light is on when the device is power on; the light is off when the device is turned off.
2) The network indicator (green) indicates whether the device get connected with network
or not. The indicator light flickers slowly with network connected, while it flickers fast
with network disconnected, this indicator is ever light during conversation.
3) The working indicator indicates the current working mode. The indicator light is off in
voice mode while the indicator light is on in fax mode.
4) The signal intensity indicators (green) display the current signal intensity. When the

signal is stronger, more indictor lights will be on, vice versa.
3.2 System Initialization
1) When the system is power on, the signal intensity indicator, working indicator and
power indicator lights are on.
2) When the system completes initialization, the power indicator light is on and the
working indicator light is off; the network indicator and signal indicator reflect the
network and signal intensity respectively.
3.3 Telephone Functions

5. Troubleshooting
5.1 Network
The GSM fixed wireless terminal needs about 15 seconds to search for local GSM

network (specific time spent subject to local network conditions).

5.3 FAQ
QHow long after startup can I dial the phone number or send/receive faxes?
AThe startup takes about 15 seconds, then the signal light is on, and the system operates in
normal state.
QCan I send/receive faxes by connecting the fax machine to the telephone port?
ANo, only the fax machine connects to the fax port can it send/receive faxes.
QWhy it spends a long time to connect to network after I dial the number?
APlease dial “#” after dialling the number, then the device will send the number immediately.
QCan I use the ordinary SIM card to send/receive faxes?
ANo. The SIM card has two numbers – the main number and associate number. The main
number sets up voice and G3 fax functions, implementing calling and fax outbound
respectively; the associate number sets up G3 fax function to receive faxes. The two
numbers are different, please contact local operator for details. As for the data set-up for
mobile SIM card, the G3 fax standard must choose TS62, namely GSM AUTOMATIC G3
FAX. Choose the speed rate as 9600bps to activate mobile fax business, then the SIM card
need to cancel the VPN to become ordinary user.
QWhen I send/receive faxes, can I make conversion first and then send faxes like fixed fax
machine?

ANo. This function requires that GSM network should support TS61.
QWhich kind of fax machine is ideal for me to choose?
AWe suggest you choose laser fax machine.
QWhy the pages draw out when I use my thermal fax machine to receive faxes?
AThe reason is that the thermal fax machine’s feed speed cannot synchronize with the
network data input speed. This situation also appears when the thermal fax machine
connects to PSTN to receive faxes. It will return to normal to use laser fax machine
instead.
