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), handsfree 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.

3-3-4 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 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.

NOTE: This software must be executed in the Windows95/98 mode.

EQUIPMENT REQUIRED

Make sure you have the following equipment setup:

1. Minimum PC configuration: 586 CPU, 16MB RAM, Windows95/98, 5MB of disk space free for software upgrade.

2. PST Software with appropriate cable (DM Cable for SAMSUNG CDMA phone).

3. Serial Port (16550 Serial Interface Card).

4. POWER SUPPLY (3.8V) OR BATTERY

INSTALLATION

Software

1.Insert the PST floppy disk into drive (A:\).

2.Create an appropriate directory on the C:\ drive for PST software, Execute Setup.exe file,

The installation program creates folder and task bar on the windows95/98 start bar.

SAMSUNG CDMA Phone

The serial port should be configured to COM1 or COM2. Use the following procedure to connect the phone, cable, and PC . Plug the female end of the DM Cable into the 16550 card.

5-2-1 Getting Started

MAIN MENU SCREEN

1. At the Windows95/98, Double Click ÒUniPst.exeÓ.

2. The Main Menu Screen will be displayed. The Main Menu Screen shows the basic tasks that are available.

CAUTION: DO NOT attempt to program phone with a low battery.

PST SETUP

UniPst supports SAMSUNG CDMA portable telephone. You can select serial port COM1 or COM2.

5-2-2 Operation Procedure

Service Programming The Service Programming screens enable you to set and change the service activation parameters of the phones. These items can be changed individually or as a group via the ÒEdit ItemsÓ Property Sheet of the PST. There are several pages on the Service Programming Property Sheet (See below Figure).

Read Data from File

Click ÒopenÓ icon to select the name of a file whose extension is ÒmmcÓ. The values will be read from the named file, and will initialize the parameter values seen on the Service programming screen

Read Data from Phone

Click Read from the Phone icon to upload the current programmable parameters of the phone. The values are read from the phone, so the phone must have the power ON and be properly connected to the PST.

NOTE: To actually view the data you need to go to the Edit Items screens.

Edit Items

Click this icon to edit Number Assignment Module (NAM) items or UI items.

There are two types of screens:

1. Parameters associated with a particular Number Assignment Module (NAM)

2. UI items settings

Phone Book

Click this icon to edit Phone Book. While you edit cell, you can use <Enter> and < UP , DOWN,LEFT,LIGHT Arrow> and <SPACE> key. If you want to edit phone number or name , you must move rectangle box to cell where you want to edit , Write it down . if <UP and DOWN Arrow> key is pressed, the cursor moves to next cell or previous cell.

5-3 SAMSUNG Proprietary-Contents may change without notice

Save Data to File

Click this icon to save the current parameters to a file. Once you enter a filename, Click <OK> button to write all current parameters to that file. This way the same information can be downloaded into multiple phones.

Write to Phone

Click this icon to write the selected parameter values to the phone. Writing the selected values to the phone may take up to a minute. If there are dependencies in a field you can make all the changes in the proper fields and download the information all together. If you intend to use this ÒWrite to PhoneÓ feature, it is recommended that you do a ÒRead Data from PhoneÓ first, and then make the changes, so that nothing gets inadvertently overwritten.

NOTE: DO NOT TOUCH THE PHONE WHILE WRITING IS IN PROGRESS.

Software Download and Upgrade Screen

To begin a software upgrade or download, perform the following steps:

1. From the main menu screen choose DOWNLOAD MODE? Click open icon to choose a BIN file of the new software to be loaded. Choose the appropriate BIN file, then Click <Open> (see below figure).

2. Click Download? to begin downloading the file. You will notice various messages and a progress bar that informs the user what percentage of the downloading has already occurred.

3.Click Mode Select box, then Select SERVICE MODE?to return to the Service Mode Screen.

NOTE: DO NOT POWER OFF WHILE THE PHONE IS BEING DOWNLOADED!

1) ==> The AB (Input Argument Byte Number) values of these commands are used only in the manual test. In automatic test mode, the AB is regarded as 0.

2) ==> You can assign the value for these commands. If the AB value is assigned without argument, the test is achieved with the value stored in EEPROM.

3) ==> After you get a desired test value by performing these commands, if you want to save the value in EEPROM, use T-SAVE-VAL-I command to store the test value into the corresponding position.
