Safety precautions
General precautions
– The modem generates radio frequency (RF) power. When using the modem care must be taken on safety issues related to RF interference as well as regulations of RF equipment.
– Do not use the modem in aircraft, hospitals, petrol stations or in places where using GSM products is prohibited.
– Be sure that the modem will not be interfering with nearby equipment. For example: pacemakers or medical equipment. The antenna of the modem should be away from computers, office equipment, home appliances, etc...
– An external antenna must be connected to the modem for proper operation. Only used approved antennas with the modem. Please contact authorized dealer on finding an approved antenna.
– Always keep the antenna with minimum safety distance of 26.6cm or more from human body.
– Do not put the antenna inside metallic box, containers, etc.
Using the modem in vehicle
– Check for any regulation or law authorizing the use of GSM in vehicle in your country before installing the modem.
– Install the modem by qualified personnel. Consult your vehicle dealer for any possible interference of electronic parts by the modem.
– The modem should be connected to the vehicle’s supply system by using a fuse-protected terminal in the vehicle’s fuse box
– Be careful when the modem is powered by the vehicle’s main battery. The battery may be drained after extended period.
Protecting your modem
To ensure error-free usage, please install and operate your modem with care. Remember the following:
– Do not expose the modem to extreme conditions such as high humidity/temperatures, rain, direct sunlight, caustic/harsh chemicals, dust, or water.
– Do not try to disassemble or modify the modem. There is no user serviceable part inside and the warranty would be void.
– Do not drop, hit or shake the modem. Do not use the modem under extreme vibrating condition.
– Do not pull the antenna or power supply cable. Please attach or detach by holding the connector.
– Connect the modem only according to the instruction manual. Failure to do it will void the warranty.

Engineering Sample known issues
Below are the know issues of the M100 3G Engineering Samples:
1. For audio, when a call is initiated, you can hear the other party but the other party cannot hear you.
2. Operating temperature range tests are still pending.
3. GPIO is available on 4-pin Molex connector but there is no analog input as on the M100evo/M100-2G.
4. Engineering Sample supports only passive GPS antenna, final product will support both passive and active
GPS antenna.
5. Engineering Sample doesn’t support CSD call, updated firmware will be provided by Sierra Wireless end of
June.
6. DCD, DSR, DTR signals are not currently available on the serial port.

General Purpose Input/Output port
This port can be configured as either an input or an output and is mapped to GPIO26 in the internal micro-controller.
– To setup this port as an input, type AT+WIOM=1,"GPIO26",0 on the serial port. Then to read the status of the input, type AT+WIOR="GPIO26" .
+WIOR: 0 means 0V while +WIOR: 1 means a positive voltage of no more than 12V. Higher voltages may damage the unit.
– To setup this port as an output, type AT+WIOM=1,"GPIO26",1 on the serial port. Then set the state of the output with AT+WIOW="GPIO26",0 for 0V, or AT+WIOW="GPIO26",1 for 2.8V.
Note: Please note that the input port is put by default to High status internally, so you just need to short it to the ground to make it low, and open to make it high.
7.3
RS232 auto-online mode (power saving)
When on auto-online mode, the RS232 transceiver will shut down most of its hardware, to save power, if it does not detect a valid input for more than 100 µs . The RS232 transceiver will wake up when valid input is detected again. By default, auto-online mode is not active. To activate it, issue AT+WIOM=1,”GPIO22”,1,0 followed by AT+WIOM=4 .
This setting needs to be set once, and will be saved in memory.

Troubleshooting
8.1
The modem’s LED does not light
– Check if the modem has been properly connected to a 5-32V power supply
– Check if the power connector is properly inserted
– Check the fuse in the power cord
8.2
The modem’s LED lights but does not blink long time after power up
– Check if a valid SIM card has been properly inserted
– Check if the SIM card has been locked (refer to AT+CPIN command in AT command guide)
– Check if the external power has been properly connected to the modem
– Check if the network coverage is available
– Make sure that the CTS and DTR pins of the serial port are not connected together
8.3
The modem does not respond to the terminal program
– Check if the RS232 cable has been properly connected
– Check if your program has proper settings. Factory setting of the modem is:
• 115200 bps
• 8 data bits
• No parity bit
• 1 stop bit 4.
8.4
No voice could be heard for the modem’s speaker output when a call is answered
– Make sure a voice call has been made (refer to AT command guide)
– Enter the AR+SPEAKER=1 command
