SAFETY 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 your phone 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 appliance, 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 26.6 cm 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. Do
remember the following:
• Do not expose the modem to extreme conditions such as high humidity/rain, high
temperatures, 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. Attach/ detach by holding the connector.
• Connect the modem only according to the instruction manual. Failure to do it will void
the warranty.

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 on the power cord
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 has been properly connected to the modem
Check if the network coverage is available
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
• 8 data bits
• No parity bit
• 1 stop bit
CHAPTER 7: RF exposure information
To maintain compliance with FCC RF exposure requirements, use handset that maintain a
20cm separation distance between the user's body and the host and antenna. MPE limit for RF
exposure at prediction frequency is 0.558mW/cm2 for GSM850MHz and 1mW/cm2 for
GSM1900MHz. The MPE for GSM850MHz is 0.488mW/cm2 and 0.277mW/cm2 for
GSM1900MHz. It satisfies RF exposure compliance.
