* Please use Windows 10 64-bit only for this model. Product capacity representation Storage capacity representation The capacity of the storage device (HDD, SSD) of the manufacturer is calculated assuming that 1 KB = 1,000 Bytes. However, the operating system (Windows) calculates the storage device capacity assuming that 1 KB = 1,024 Bytes. Therefore, the available capacity of the HDD in Windows is smaller than the actual capacity due to the difference in capacity calculation. For example, for an 80 GB HDD, Windows calculates the capacity as 74.5 GB, (80x1,000x1,000x1,000) Bytes/(1,024x1,024x1,024) Bytes

= 74.505 GB. In addition, the capacity representation in Windows may be even smaller because some programs, such as Samsung Recovery, may reside in a hidden area of the HDD. Memory capacity representation The available memory capacity in Windows is less than the actual capacity of memory. This is because some memory is required for regular system operations. For example, for 1 GB (= 1,024 MB) memory installed, Windows may report the capacity as 1,022 MB or less. 6 Getting started Layout Features or options may differ depending on the model. The items marked as optional may not be provided or may be provided in different locations. Since some space on the SSD is reserved for system recovery and operations, the available space on the SSD may be less than the actual capacity. 7 Getting started Front view 1 Number/Name Camera indicator light Microphone Camera LCD Operating status LED Description This indicates the camera operating status.

The computer has an additional partition for restoring data or saving backup files (only for models with the Samsung Recovery application). This partition is called a Recovery Area and it includes a recovery image comprised of the operating system and applications. Why is the capacity representation of the hard disk drive (HDD) in Windows different from the product specifications?

The capacity of the storage device (HDD or SSD) of the manufacturer is calculated assuming that 1 KB = 1,000 Bytes. However, the operating system (Windows) calculates the storage device capacity assuming that 1 KB = 1,024 Bytes, and therefore the capacity representation of the HDD in Windows is smaller than the actual capacity. The capacity representation in Windows may be smaller than the actual capacity because some applications occupy a certain area of the HDD outside of Windows. For models with the Samsung Recovery application, the HDD capacity representation in Windows may be smaller than the actual capacity because the Samsung Recovery application uses a hidden area of 520 GB of the HDD to save the recovery image, and that hidden area is not counted towards the total size available to Windows. The size of the Samsung Recovery application varies by model. 59 Troubleshooting What is a recovery image?

Miscellaneous This refers to the operating system, drivers, and software that are converted to a data image. It is required to recover the computer and is embedded in the computers HDD. However, this is not provided for storage devices where the capacity is less than 64 GB, due to their small capacities. How can I restore a computer that does not have the Samsung Recovery application?

Wireless devices are closely regulated and use may not be allowed. 82 Appendix Radio frequency wireless communication can interfere with equipment on commercial aircraft. Current aviation regulations require wireless devices to be turned off while traveling in an airplane. 802.11ABGN (also known as wireless Ethernet or Wi-Fi) and Bluetooth communication devices are examples of devices that provide wireless communication. In environments where the risk of interference to other devices or services is harmful or perceived as harmful, the option to use a wireless device may be restricted or eliminated. Airports, hospitals, and oxygen or flammable gas laden atmospheres are limited examples where use of wireless devices may be restricted or eliminated. When in environments where you are uncertain of the sanction to use wireless devices, ask the applicable authority for authorization prior to use or turning on the wireless device. Every country has different restrictions on the use of wireless devices. Since your system is equipped with a wireless device, when traveling between countries with your system, check with the local Radio Approval authorities prior to any move or trip for any restrictions on the use of a wireless device in the destination country. If the system came equipped with an internal embedded wireless device, do not operate the wireless device unless all covers and shields are in place and the system is fully assembled. Wireless devices are not user serviceable. Do not modify them in any way. Modification to a wireless device will void the authorization to use it. Please contact the manufacturer for service. Only use drivers approved for country in which the device will be used. See the manufacturer System Restoration Kit, or contact the manufacturers technical support for additional information. 83 Appendix United States of America USA and Canada Safety Requirements and Notices Do not touch or move antenna while the unit is transmitting or receiving. Do not hold any component containing the radio such that the antenna is very close to touching any exposed parts of the body, especially the face or eyes, while transmitting. Do not operate the radio or attempt to transmit data unless the antenna is connected; if not, the radio may be damaged. The use of wireless devices in hazardous locations is limited by the constraints posed by the safety directors of such environments. The use of wireless devices on airplanes is governed by the Federal Aviation Administration (FAA). The use of wireless devices in hospitals is restricted to the limits set forth by each hospital. Explosive Device Proximity Warning Do not operate a portable transmitter (such as a wireless network device) near unshielded blasting caps or in an explosive environment unless the device has been modified to be qualified for such use. Use On Aircraft Caution Regulations of the FCC and FAA prohibit airborne operation of radio-frequency wireless devices because their signals could interfere with critical aircraft instruments.

Exposure to Radio Frequency (RF) Signals Certification Information This product can contain an embedded 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 Council 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. Before a new model is available for sale to the public, it must be certified to the FCC that it does not exceed the exposure limit established by the FCC. Evaluation per each model is performed in positions and locations (e.g. at the bottom on the body) as required by the FCC. 87 Appendix For body worn operation, this model meets the FCC RF exposure guidelines when used with Samsung accessory designated for this product. Non-compliance with the above restrictions may result in violation of FCC RF exposure guidelines. RF exposure or SAR information can be viewed on-line at www.fcc.gov/oet/ea/fccid/. This site uses this product FCC ID number on the outside of the product. Sometimes it may be necessary to remove the battery pack to find number. Once you have the FCC ID number for a particular product, follow the instructions on the website and it should provide RF exposure information or values for typical or maximum SAR for particular product. For corresponding model only The Specific Absorption Rate (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 wireless devices to comply with a safety limit of 1.6 watts per kilogram (1.6 W/kg). SAR level of this device while operating can be well below the maximum value. This is because the device 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. 88 RTC caution CAUTION: Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type recommended by the manufacturer. Discard used batteries according to the Manufacturers instruction.
