the installation procedure for Microsoft Windows XP-based notebooks and PCs. Normal modem interaction is
achieved through a notebook/PC dial-in, to access the AT-command set via a serial link, e.g. for access to the
internet or dialing a call.
Note that GSM-only users should ignore all references to GPRS functionally and features.
Damage to the RF power-amp may occur if the modem is powered-up without a suitable antenna, or the antenna i
disconnected whilst the modem is powered. Note the modem may be supplied with an in-built helix antenna (right
hand picture in 4.2 below) or with a connector (left-hand picture) for an external antenna.
If the modem is being correctly operated, and yet does not provide a connection to the internet from your PC,
please check your PC fire-wall settings.
