1 Safety Precautions
1.1 General precautions
The modem generates radio frequency (RF) power. When using
the modem, care must be taken to ensure safety as well as
compliance with all the regulations surrounding the use of RF
equipment.
Do not use the modem in aircraft, hospitals and petrol stations or
in places where using GSM products or other RF equipment is
prohibited.
Be sure that the modem will not be interfering with nearby
equipment such as pacemakers or medical equipment. The
antenna of the modem should be directed away from computers,
office equipment, home appliance, etc.
Always keep the modem at a minimally safe distance of 26.6cm or
more from a human body.
Do not put the antenna inside metallic boxes or other containers
1.2 Using the modem in vehicle
Check for any regulation or law authorizing the use of GSM
equipment in vehicles in your country before installing the
modem.
Installation of the modem should be done by qualified personnel.
Consult your vehicle dealer for any possible interference
concerns related to the use of the modem.
Be careful when the modem is powered by the vehicle’s main
battery. The battery may be drained after extended period.
1.3 Protecting your modem

supply source.
16 Bailing M40 Series www.bailing88.com
9 Communicating with the M40
After setting up the M40, communications can be established by directly
sending AT commands to the device using terminal software such as
HyperTerminal for MS Windows. The following sub-sections describe how this
is done.
9.1 Communications Testing for the M40
To perform a communications test after the M40 has been setup, do the
following:
Connect the RS-232 link between the external application
(DTE) and the M40 (DCE).
Configure the RS-232 port of the DTE as follows:
• Bits per second: 115, 200bps
• Data bits: 8
• Parity: None
• Stop Bits: 1
• Flow control: hardware
Using a communication software such as HyperTerminal,
enter:
AT↵
When communications have been established, the M40 will
respond with an “OK”, which is displayed in the
HyperTerminal window.
If communications cannot be established with the M40, do the following:
Check the RS-232 connection between the application (DTE)
and the M40 (DCE).
Check the configuration of the COM port used on the DTE
17 Bailing M40 Series www.bailing88.comRefer to the table below for other AT commands that can be used after getting
the M40 started.
AT Command Description
AT+CGMI To check if the serial link is OK. The M40 will respond with "Sierra
Wireless" when it is OK.
AT+CPIN=xxxx To enter a PIN code, xxxx (if activated).
AT+CSQ To verify the received signal strength.
AT+CREG? To verify the registration of the M40 on the network.
ATD<phone number> To initiate a voice call.
ATH To hang up (end of call).
Table: Basic AT Commands for the M40
9.2 Verifying the Received Signal Strength
The M40 only establishes a call if the received signal strength is strong
enough. Using communication software such as HyperTerminal, enter
AT+CSQ to check the received signal strength. The response returned will
follow the format +CSQ: <rssi>, <ber>
where:<rssi> = received signal strength indication, and <ber> = channel bit
error rate.
Refer to the table below for the description of the <rssi> values returned.
<rssi> Value Description
0 – 10 Received signal strength may be insufficient.
11 – 31 Received signal strength is sufficient.
32 – 98 Not defined.
99 No measure available.
Table: <rssi> Value Description
9.3 Verifying the Network Registration
To check the network registration, make sure that a valid SIM card has been
properly inserted into the M40.
Note: When using the M40 with Embedded SIM, ensure that the
device has been registered by the network provider.
18 Bailing M40 Series www.bailing88.comUsing a communication software such as HyperTerminal, enter AT+CREG?
to verify the network registration of the M40. Refer to the table below for the
list of main responses returned.
AT+CREG Response Description
+CREG: 0,0 Not registered.
+CREG: 0,1 Registered on the home network.
+CREG: 0,5 Registered on a roaming network.
Table: AT+CREG Main Reponses
If the M40 is not registered on the network, do the following:
Check the connection between the M40 and the antenna.
Verify the signal strength to determine the received signal
strength (refer to section 8.2 Verifying the Received Signal
Strength).
9.4 Checking the PIN Code Status
Using a communication software such as HyperTerminal, enter AT+CPIN? to
check the PIN code status. Refer to the table below for the list of main
responses returned.
AT+CPIN Response Description
+CPIN: READY The PIN code has been entered.
+CPIN: SIM PIN The PIN code has not been entered.

20 Bailing M40 Series www.bailing88.com9.6 Echo Function
If no echo is displayed when entering an AT command, it could mean either of
the following:
The “local echo” parameter of your communication software
such as HyperTerminal is disabled.
The M40 echo function is disabled.
To enable the M40 echo function, enter the AT command ATE1.
When sending AT commands to the M40 using a communication software
such as HyperTerminal, it is recommended to:
Disable the “local echo” parameter of your communication
software
Enable the M40 echo function (use the ATE1 AT command)
In a machine-to-machine communication with the M40, it is recommended to
disable the M40’s echo function (using the ATE0 AT command) in order to
avoid useless CPU processing.
