Sony Ericsson PC300 - Manual (Page 7)

Overview 3
The external antenna connector is an MMCX pattern.
The PC300 is a 3.3 volt PC card and has mechanical keying to prevent insertion in older 5 volt only
PCMCIA slots. Laptops 'Designed for Windows 98' and onwards have 3.3 volt support.
The amount of power that your PC300 draws from the laptop battery depends on several factors,
including status, frequency band, and distance to the base station that is used.
The PC300 can be turned off under software control from the Wireless Manager application or the
signal strength icon in the status tray. It is recommended that the user remove the card from the laptop
when flying to prevent any accidental transmission.
Protective Case
When it is not in use, you should store your PC300 in the protective case. You can affix a lanyard
to the case if required, so that you can carry your PC300 around your neck. The protective case can
also accomodate the accessory antenna.
Accessory Antenna GCA-14
GCA-14 is an accessory antenna to be used with PC300 Mobile Broadband PC Card in order to enhance
signal strength when using your PC Card in areas far from base stations or in areas with low GSM
or UMTS network signal strength.
