Specific Absorption Rate (IEEE)

Your model wireless phone meets the governmental requirements for exposure to radio waves.

Your mobile device is a radio transmitter and receiver. It is designed and manufactured to not exceed limits for exposure to radio frequency (RF) energy set by the Federal Communications Commission (FCC) of the U.S. Government and by the Canadian regulatory authorities. These limits are part of comprehensive guidelines and establish permitted levels of RF energy for the general population. The guidelines are based on standards that were developed by independent scientific organizations through periodic and thorough evaluation of scientific studies. The standards include a substantial safety margin designed for the safety of all persons, regardless of age or health, and to account for any variations in measurements.

The exposure standard for mobile devices employs a unit of measurement known as the Specific Absorption Rate (SAR). The IEEE SAR limit set by the FCC and by the Canadian regulatory authorities is 1.6 watts per kilogram (W/kg), averaged over one gram of tissue. Tests for SAR are conducted using procedures accepted by the FCC and by Industry Canada with the mobile device transmitting at its highest certified power level in all tested frequencies. Although the SAR is determined at the highest certified power level, the actual SAR level of the mobile device while operating can be below the maximum value. This is because the mobile 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, the lower the power output.

Before a mobile device is available for sale to the public in the U.S. and Canada, it must be tested and certified to the FCC and Industry Canada that it does not exceed the limit established by each government for safe exposure. The tests are performed in positions and locations (e.g., at the ear and worn on the body) submitted to the FCC and available for review by Industry Canada. The highest SAR value for this mobile device when tested for use at the ear is 1.32 W/kg, and when worn on the body, as described in this guide, is

0.94W/kg. The SAR value for this mobile device in its data transmission mode (body-worn use) is 0.23 W/kg. Body-worn measurements can differ, depending upon available accessories and regulatory requirements. The SAR information includes the Motorola testing protocol, assessment procedure, and measurement uncertainty range for this product.

XT300 specifications

The Motorola XT300, commonly known as the Motorola Backflip, is a unique smartphone that gained popularity for its innovative design and features when it was launched in 2010. This device represents a distinctive approach to smartphone ergonomics and functionality, appealing particularly to users looking for a combination of style and practicality.

One of the standout characteristics of the XT300 is its flip design, which allows the phone to rotate around its hinge. This design not only protects the screen when closed but also utilizes a unique rear-facing keyboard that flips open to reveal a QWERTY layout. This keyboard enhances text input efficiency, catering to users who frequently type messages or emails. The display features a 3.1-inch capacitive touchscreen with a resolution of 320 x 480 pixels, providing vibrant colors and decent clarity for viewing photos, videos, and apps.

The Motorola XT300 operates on the Android 2.1 Eclair platform, which was considered cutting-edge at the time of its release. This operating system provided users with access to a multitude of applications through the Android Market, enabling customization and enhanced functionality. The device comes equipped with an 528 MHz ARM 11 processor, which, while modest by today’s standards, facilitated smooth operation for casual applications and general usage during its era.

In terms of connectivity, the XT300 supports 3G HSPA networks and Wi-Fi, allowing for quick internet access and streaming capabilities. The device also features Bluetooth for connecting various accessories like headsets or keyboards, increasing its versatility.

The camera on the XT300 is a 5-megapixel shooter, featuring autofocus and LED flash, which enables users to capture decent quality photos and videos. While it might not compete with modern smartphone cameras, it was suitable for casual photography during its time.

Battery life is another notable feature of the Motorola XT300, with a removable 1400 mAh battery that offers a respectable standby time, catering to users who rely on their phones throughout the day. With its balance of unique design, functionality, and features, the Motorola XT300 remains a memorable smartphone from the early days of Android devices, showcasing Motorola's commitment to innovation in mobile technology.
