OPERATION
Every time you use the M2M 3350 you should make sure that all other internet connections are
disabled. You will most likely need to connect to the modem before each use if you often
disconnect it from the PC. The typical bandwidth is 30-40kbps, similar to a dial-up 56kbps
modem.

LED Operation
The following defines the states of the LEDs on the front of the unit.
LED
PWR
GSM
COM
Note: A flashing GSM LED does not necessarily mean the unit is connected to GPRS but only
means the unit has registered with the GSM network.
6.2
SIM Card Tray
The SIM card must be placed in the SIM card tray. To eject the tray, press the yellow button with
a pen. The tray should insert easily into the holder. If it must be forced, it is not in right and you
should retry.
6.3
USB/COM Switch
To use the modem in USB mode, the selector switch must be set to 'USB'. The COM LED will be
turned off when in USB mode. To use the modem in serial mode or with the Bluetooth dongle the
selector switch must be set to 'COM'. The COM LED will be steady on yellow. In either case,
the USB cable must be connected to either a USB port or another power source as this is the main
power input.

Power
The USB port provides power to the modem. This must be connected to a USB port or the car
adapter. The input is 5V DC and the current rating must be >500mA.
