1. General Description

The SCH-620 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-620 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.

IMPORTANT INFORMATION Purpose

The Product Support Tool (PST) offers you the ability to interface with the SAMSUNG CDMA telephone using a PC. With this tool you can program the phones network system requirements and functionality, swap phone data, and download software upgrades. This document supports UniPST version 1.xx.

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 (3.8 V) or Battery

INST

ALLATION

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.
