Samsung Electronics-Contents may change without notice. 1-1
The SCH-211 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:
¥ UIS-95A : Mobile Station-Base Station Compatibility Standard for Dual-Mode Wideband Spread Spectrum
Cellular System
¥ UIS-96A : Speech Service Option 1 Standard for Dual-Mode Wideband Spread Spectrum Cellular Systems
¥ UIS-98A : Standards for Dual-Mode Wideband Spread Spectrum Cellular Mobile Station
¥ UIS-126 : Mobile Station Loopback Service Options Standard
SCH-211 is composed of main handset, rapid charger, cradle, two batteries (1300 mAh, 850 mAh), hands-free
kit, and travel charger. Hands-Free Kit is designed to be operated in half-duplex mode taking turn-around
delay between the phone and the system into account.

3-3-1 Antenna
1. Choose a proper location to install the
antenna.
¥ UThe center of the roof top provides the
best performance.
¥ UThe edge of the rear trunk also provides a
good performance. However, the antenna
should be higher than the roof of the car.
¥ UIn case of on-glass antenna, you should
align the antenna base with the round plate
to connect the cables correctly.
2. Mount the antenna vertically, connect the
antenna cable.
3. Tighten the antenna nut fully.

Installation
3-3-2 Cradle
1. Choose a location where it is easy to reach
and does not interfere with the driverÕs safe
operation of the car.
2. Separate the two halves of the clamshell by
removing the two large slotted screws. See the
figure 3-2.
3. Drill holes and mount the lower half of the
clamshell by using the screws.
4. Place the cradle onto the remaining half of the
clamshell and assemble them by using the
screws.
5. Reassemble the two halves of the clamshell
together. Adjust the mounting angle and
tighten the two slotted screws.

2. Install the hands-free box into the bracket.
3-3-4 Hands-Free Microphone
1. It is recommended to install the microphone
where it is 30-45 cm (12-18Ó) away from the
driver. Choose the location where is least
susceptible to interference caused by external
noise sources, ie, adjacent windows, radio
speakers, etc. Normal place is the sun visor.
2. Once the microphone has been correctly
positioned, connect the microphone wire to
the MIC jack on the hands-free box.

Installation
3-3-5 Cables
1. Connect the cradle and the hands-free box
with the data cable. See the figure 3-4.
2. Connect the antenna cable to the RF jack of
the cradle.
3. Connect the power cable as follows:
Connect the red wire to the battery (+) termi-
nal, black wire to the battery (-) terminal.
Then connect the orange wire to the switched
side of the ignition switch, and then connect
the brown wire 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.
