1. General Description
The SCH-811 cellular phone functions as both analog cellular phone working in AMPS (Advanced Mobile
Phone Service) mode and digital cellular phone working in CDMA (Code Division Multiple Access) mode.
CDMA type digital mode applies DSSS (Direct Sequential Spread spectrum) mode which first came to be used
in the military.
The DSSS reduces channel cross talk and allow to use one frequency channel by multiple users in the same
specific area, resulting in increase of channel capacity to about ten times compared to that of analog mode
currently used.
Soft/Softer Handoff, Hard Handoff, and Dynamic RF Power Control technologies are combined into this phone
to reduce the call drop while usage.
CDMA digital cellular network consists of MSO (Mobile Switching Office), BSC (Base Station Controller),
BTS(Base Station Transmission System), and MS (Mobile Station). MS meets the specifications of the below:
E IS-95A : Mobile Station-Base Station Compatibility Standard for Dual-Mode Wideband Spread Spectrum
Cellular System
E IS-96A : Speech Service Option 1 Standard for Dual-Mode Wideband Spread Spectrum Cellular Systems
E IS-98A : Standards for Dual-Mode Wideband Spread Spectrum Cellular Mobile Station
E IS-126 : Mobile Station Loopback Service Options Standard
SCH-811 is composed of main handset, rapid charger, three batteries (1600 mAh, 1000 mAh, 550mAh), hands-
free kit, car adaptor, and travel charger. Hands-Free Kit is designed to be operated in full-duplex mode taking
turn-around delay between the phone and the system into account.

Connect the red wire to the battery (+) terminal, black wire to the vehicle chassis. Then connect the battery (-)
terminal to the vehicle chassis. Connect the yellow wire to the switched side of the ignition switch, and then
connect the white to the stereo mute wire from your vehicle stereo.
4. Connect the other end of the power cable to the PWR jack of the hands-free box.
Notes:
It is recommended to connect the power cable directly to the battery to avoid power noise.
Make sure the connection, in the vehicle, between the battery (-) terminal and vehicle chassis is made correctly.
Make sure the fuse having a proper capacity is used on the power cable.
Make sure the cables do not pass over any sharp metal edge that may damage it.
