the power up part, MCU also acts as a Watch Dog, when the terminal runs wrong, MCU will cut off the power

and recover it immediately to restart the terminal.

6.2 Serial Interface

T5320+G provides one asynchronous RS232 serial port (female).The RS232 standard interface serves to connect

a PC, Data Terminal Equipment (DTE) or other application, which acts as host controller of the T5320+G

Terminal with all its functions. Through the RS232 interface it can be used as GSM/GPRS modem for sending

and receiving of SMS, Data and Fax calls.

6.3.1 Audio interface

T5320+G has one pair of audio input and audio output; it can be connected to a speakerphone directly.

Figure 13: Speaker reference circuit

Firstly, customer must use the “AT +CSDVC=3” to select speaker audio channel.

Customer can set the terminal MIC gain level to make the sounds louder so that the listener can hear more clearly.

And if the sound a little lower on the terminal side, customer can use the “AT +CLVL” to make the sound higher

so that customer can hear clearly.

The AT commands should be send to the terminal by RS232 or USB interface, and the following table shows the

detail commands.

C. Safety Caution

Table 25: Safety caution

Marks Requirements

When in a hospital or other health care facility, observe the restrictions about the use of mobiles.

Switch the cellular terminal or mobile off, medical equipment may be sensitive to not operate

normally for RF energy interference.

Switch off the cellular terminal or mobile before boarding an aircraft. Make sure it is switched off.

The operation of wireless appliances in an aircraft is forbidden to prevent interference with

communication systems. Forget to think much of these instructions may lead to the flight safety or

offend against local legal action, or both.

Do not operate the cellular terminal or mobile in the presence of flammable gases or fumes. Switch

off the cellular terminal when you are near petrol stations, fuel depots, chemical plants or where

blasting operations are in progress. Operation of any electrical equipment in potentially explosive

atmospheres can constitute a safety hazard.

T5320+G_User Guide_V1.01 37 2013-04-15

Smart Machine Smart Decision

Your cellular terminal or mobile receives and transmits radio frequency energy while switched on.

RF interference can occur if it is used close to TV sets, radios, computers or other electric

equipment.

Road safety comes first! Do not use a hand-held cellular terminal or mobile when driving a

vehicle, unless it is securely mounted in a holder for hands free operation. Before making a call

with a hand-held terminal or mobile, park the vehicle.

GSM cellular terminals or mobiles operate over radio frequency signals and cellular networks and

cannot be guaranteed to connect in all conditions, for example no mobile fee or a invalid SIM card.

While you are in this condition and need emergent help, please remember using emergency calls.

In order to make or receive calls, the cellular terminal or mobile must be switched on and in a

service area with adequate cellular signal strength.

Some networks do not allow for emergency call if certain network services or phone features are in

use (e.g. lock functions, fixed dialing etc.). You may have to deactivate those features before you

can make an emergency call.

Also, some networks require that a valid SIM card be properly inserted in the cellular terminal or

mobile.
