Safety Precautions Compliance with Safety Standards The Samsung Cellular phone meets all standards and recommendations for the protection of the public from exposure to radio frequency (RF) electromagnetic energy established by governmental bodies and other qualified organizations. To reduce the risk of fire, electric shock, serious personal injury, or property damage, please follow these guidelines: Driving Using a wireless phone while driving is illegal in some states and countries. Know the laws and regulations for your area, and pull off the road and park if you need to make a call. If you must use the phone while driving, purchase and install the optional Hands-Free Car Kit. Electronic Devices Your wireless telephone is a radio transmitter and receiver. When the power is on, the phone receives and sends out RF energy. Most modern electronic equipment, such as equipment and cars, contains an RF signal shield. RF energy may affect some inadequately shielded electronic equipment. Turn off tour phone in health care facilities, and always request pacemakers and hearing aids, to determine if they are shielded adequately from external RF signals. Note if there are any regulations posted in area regarding the operation of wireless phones, and learn where you can use them safely within facility. Aircraft Turn off your phone before boarding any aircraft. The Federal Aviation Administration (FAA) requires that you have prior permission from the crew to use your phone while the plane is on the ground. FCC regulations prohibit using your phone is in the air. Do not use your phone at any time while traveling on board a plane. SPH-i325 Quick Reference.doc 3/28
Blasting Areas Construction crews often use remote-control RF devices to set off explosives. To avoid interfering with blasting operation, turn off your phone when you are in a blasting area or in any area with signs posted as "Turn off two-way radio." Other Dangerous Areas Turn off your phone in any area with a potentially explosive atmosphere. It is rare, but your phone or its accessories could generate sparks, which could explosion or fire. * Fueling areas, such as gas stations * Below deck on boats * Furl or chemical transfer or storage facilities * Areas where the air contain chemicals or particles such as grain, dust, or metal powders * Any other area where you would normally be advised to turn off your vehicle engine Do not transport or store flammable gas, liquid, or explosives in the compartment of a vehicle containing your or accessories. Certification Information (SAR) Your wireless phone is a radio transmitter and receiver. It is designed and manufactured not to exceed the exposure limits for radio frequency (RF) energy set by the Federal Communications Commission(FCC) of the U.S. government. These FCC exposure limits are derived from the recommendations of two expert organizations, the National Counsel on Radiation Protection and Measurement (NCRP) and the Institute of Electrical and Electronics Engineers (IEEE). In both cases, the recommendations were developed by scientific and engineering experts drawn from industry, government, and academia after extensive reviews of the scientific literature related to the biological effects of RF energy. The exposure limit set by the FCC for wireless mobile phones employs a unit of measurement known as the Specific Absorption Rate (SAR). The SAR is a measure of the rate of absorption of RF energy by the human body expressed in units of watts per kilogram (W/kg). The FCC requires wireless phones to comply with a safety limit of 1.6 watts per kilogram (1.6W/kg). The FCC exposure limit incorporates a substantial margin of safety to give additional protection to the public and to account SPH-i325 Quick Reference.doc 4/28
for any variations in measurements. SAR tests are conducted using standard operating positions accepted by the FCC with the phone transmitting at its highest certified power level in all tested frequency bands. Although the SAR is determined at the highest certified power level, the actual SAR level of the phone while operating can be well below the maximum value. This is because the phone is designed to operate at multiple power levels so as to use only the power required to reach the network. In general, the closer you are to a wireless base station antenna, the lower the power output. Before a new model phone is available for sale to the public, it must be tested and certified to the FCC that it does not exceed the exposure limit established by the FCC. Tests for each model phone are performed in positions and locations (e.g. at the ear and worn on the body) as required by the FCC. The highest SAR values for this model phone as reported to the FCC are : CDMA Mode Head: 1.00 W/Kg, Body-worn: 1.28 W/Kg, PCS Mode Head : 1.36 W/Kg, Body-worn: 0.862 W/Kg. For body worn operations, this model phone has been testde and meets the FCC exposure guidelines when used with a Samsung accessory designated for this product or when used with an accessroy that contains no metal and that positons the handset a minimum 1.5 cm from the body. Non-compliance with the above restrictions may result in violation of FCC RF exposure guidelines. SAR information on this and other model phones can be viewed on-line at www.fcc.gov/oet/fccid. This site uses the phone FCC ID number A3LSPHI325 Sometimes it may be necessary to remove the battery pack to find the number. Once you have the FCC ID number for a particular phone, follow the instructions on the website and it should provide values for typical or maximum SAR for a particular phone. Additional product specific SAR information can also be obtained at www.fcc.gov/cgb/sar. SPH-i325 Quick Reference.doc 5/28

Synchronizing Information This chapter introduces the basic features of Microsoft® ActiveSync® technology. It describes how to use ActiveSync for synchronizing information on your Smartphone with your desktop computer and/or a server running Microsoft® Exchange® Server. For detailed information about using ActiveSync, see ActiveSync Help on your desktop computer. Understanding ActiveSync ActiveSync synchronizes information stored on your Smartphone with Microsoft® Outlook® information on your desktop computer or Microsoft Exchange Server. It also allows you to share files between your device and your desktop computer. When you synchronize, ActiveSync compares the information on your device with the information on your desktop computer and/or Exchange Server and updates all locations with the most recent information. With ActiveSync, you can:  Synchronize Inbox, Contacts, Calendar, and Tasks information on your device with your desktop computer.  Synchronize Inbox, Contacts, and Calendar on your device with the Outlook information on a server running Microsoft Exchange Server so that you have the latest information, even when your desktop computer is turned off. You can synchronize Tasks information with your desktop computer, but not with a server. You can synchronize with an Exchange server if your company or service provider is running Microsoft Exchange Server with Exchange ActiveSync.  Copy (rather than synchronize) files between your device and your desktop computer.  Synchronize on a schedule to control when synchronization occurs.  Select which types of information are synchronized and specify how much information is synchronized. For example, you can choose how many weeks of past appointments to synchronize. Setting up ActiveSync Using Microsoft ActiveSync, you can synchronize information on the device with your SPH-i325 Quick Reference.doc 26/28
desktop computer and/or Microsoft Exchange Server. This section explains how to:  Install ActiveSync on your desktop computer.  Create a partnership between your desktop computer and the device.  Configure an Exchange Server connection (if you will be synchronizing with a corporate or service provider server running Microsoft Exchange Server with Exchange ActiveSync).  Set up a synchronization schedule. If you want to keep the information on your device always up to date, set up ActiveSync to synchronize as items arrive. You can synchronize as items arrive only if your company or service provider is running Microsoft Exchange Server with Exchange ActiveSync. Installing ActiveSync and creating a partnership Before you can synchronize information with a desktop computer, you must first install ActiveSync on your desktop computer and create a partnership between your Smartphone and your desktop computer. You can also set up synchronization between the Smartphone and a Microsoft Exchange server at this time. You can install ActiveSync on the desktop computer from the Smartphone Companion CD. For more information about installing ActiveSync, see the Quick Start Information. ActiveSync is already installed on your Smartphone. As soon as ActiveSync installation completes, the New Partnership Wizard automatically starts. This wizard helps you set up a partnership between your Smartphone and your desktop computer or with an Exchange server. When you create a partnership, you specify your synchronization settings; for example, the type of information to synchronize, whether or not to synchronize with both your desktop computer and an Exchange server. Once a partnership is set up, ActiveSync on your desktop computer recognizes your Smartphone when you connect it, and automatically applies the synchronization settings you specified. When you finish using the wizard, the first synchronization begins automatically. When synchronization completes, you will notice that the information from your desktop computer or Microsoft Exchange Server that you selected now appears on your Smartphone. Before you begin setting up ActiveSync, you should get the information you will need and connect the device to your computer. SPH-i325 Quick Reference.doc 27/28

GH68-08136AHearing Aid Compatibility with Mobile PhonesWhen some mobile phones are used near some hearing devices (hearing aids and cochlear implants), users may detect a buzzing, humming, or whining noise. Some hearing devices are more immune than others to this interference noise, and phones also vary in the amount of interference they generate. The wireless telephone industry has developed ratings for some of their mobile phones, to assist hearing device users in finding phones that may be compatible with their hearing devices. Not all phones have been rated. Phones that are rated have the rating on their box or a label on the box. The ratings are not guarantees. Results will vary depending on the user’s hearing device and hearing loss. If your hearing device happens to be vulnerable to interfer-ence, you may not be able to use a rated phone successfully. Trying out the phone with your hearing device is the best way to evaluate it for your personal needs. M-Ratings: Phones rated M3 or M4 meet FCC requirements and are likely to gener-ate less interference to hearing devices than phones that are not labeled. M4 is the better/higher of the two ratings. T-Ratings: Phones rated T3 or T4 meet FCC requirements and are likely to be more usable with a hearing device’s telecoil (“T Switch” or “Telephone Switch”) than unrated phones. T4 is the better/higher of the two ratings. (Note that not all hearing devices have telecoils in them.) Hearing devices may also be measured for immunity to this type of interference. Your hearing device manufacturer or hearing health professional may help you find results for your hearing device. The more immune your hearing aid is, the less likely you are to experience interference noise from mobile phones.
