1. General Introduction
The SCH-210 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:
IS-95A : Mobile Station-Base Station Compatibility Standard for Dual-Mode Wideband Spread Spectrum
Cellular System
IS-96A : Speech Service Option 1 Standard for Dual-Mode Wideband Spread Spectrum Cellular Systems
IS-98A : Standards for Dual-Mode Wideband Spread Spectrum Cellular Mobile Station
IS-126 : Mobile Station Loopback Service Options Standard
SCH-210 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.

3-1 Installing a Battery Pack
1. To attach the battery pack after charging, align
it with the phone about 1cm (1/2") away from
its place so that the two arrows on the phone
are seen, the battery charge contacts pointing
downward.
2. Slide the battery pack upwards until it clicks
firmly into position. The phone is now ready
to be turned on.
3. To remove the battery pack, release it by
pressing the button on the rear of the phone.
4. Slide the battery pack downward about 1cm
(1/2") and lift it away from the phone.
3-2 For Desk Top Use
1. Choose a proper location to install the charger
for desk top use.
2. Plug the power cord of the charger into an
appropriate wall socket. When the power is
connected correctly, the lamps turn on briefly.
3. To charge the battery pack, insert the battery
pack into the rear slot of the charger. The lamp
marked BAT on the front panel of the charger
lights up red.
4. If you do not wish to use the phone while
charging the battery, insert the phone with the
battery pack attached into the front slot of the
charger. The lamp marked PHONE on the
front panel of the charger lights up red.
Press this button to release
the battery pack

antenna.
The center of the roof top provides the best
performance.
The edge of the rear trunk also provides a
good performance. However, the antenna
should be higher than the roof of the car.
In 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.

3-3-2 Cradle
1. Choose a location where it is easy to reach and
does not interfere with the driver's 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.

3-3-3 Hands-Free Box
1. Drill holes in a proper location for the hands-
free box, attach the mounting bracket by using
the screws. See the figure 3-3.
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 (12-18") 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.

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 (+)
terminal, 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.
