zInstall the modem driver software following the procedure defined in our software
installation user guide.
zInsert the SIM card into the SIM card holder with the correct direction (the SIM
Card’s chamfered corner must match with the latch on the housing).

I2R GSU-600 Wireless Modem User Guide
zConnect the modem and USB port with the USB extender cord（see note）.
zThen the modem is powered on from the USB ports
NOTE: The extender cord is a three ports unit, port 1 and port 2 are together for the
PC side, port 1 is used to get power from the PC and simultaneously transmit data between
the PC and the modem (see figure 4 & figure 5), port 2 is only used to get power from
the PC to enhance the power supply of the modem, it can ’t be used to transmit data (see
figure 4&figure 7); Port 3 is only for the modem (see figure 4 & figure 5):

We do not recommend inserting only port 1 to the PC side to start up the modem (see figure 6), in this way ,
the modem can not work steadily in the case of heavy load during data transmitting, since only one USB
port can not afford so much current, please refer to chapter 7.
