This document serves as a user manual for the Infinix X6815B, providing essential information for its operation, maintenance, and compliance. The manual begins with an explosion diagram, detailing the internal components of the device, followed by a "Know your phone" section that highlights external features and their functions. Subsequent sections cover SIM/SD card installation, charging procedures, and important FCC compliance statements, including SAR information.
The Infinix X6815B is a mobile phone designed for communication and various smart device functionalities. Its core function is to facilitate wireless communication, allowing users to make calls, send messages, and access data networks. The device is equipped with a front camera, enabling users to capture selfies, participate in video calls, and use facial recognition features if available. The volume keys (Volume + and Volume -) are provided for adjusting audio levels during calls, media playback, and notifications. A combined Power key and side fingerprint sensor offers a convenient and secure method for turning the device on/off, locking/unlocking the screen, and authenticating user access through fingerprint recognition.
For usage, the device supports the installation of SIM and SD cards. The manual instructs users to power off the mobile before attempting to install these cards, emphasizing the importance of following the provided visual guide for correct placement. This ensures proper recognition of the SIM card for network connectivity and the SD card for expanded storage.
Charging the Infinix X6815B is a straightforward process. Users can charge the device by connecting it to a charger or a computer using a USB cable, which is included with the phone. A critical maintenance feature highlighted in the manual is the recommendation to use only INFINIX brand chargers and cables. This is not merely a suggestion but a warning, as using other chargers or cables may damage the device and, importantly, invalidate the phone's warranty. This emphasizes the need for users to adhere to manufacturer-specified accessories to ensure the longevity and warranty coverage of their device.
The manual also includes a comprehensive FCC Statement, which is crucial for understanding the device's regulatory compliance. The device complies with Part 15 of the FCC Rules, meaning it is designed not to cause harmful interference and must accept any interference received. Users are informed that unauthorized changes or modifications could void their authority to operate the equipment. The FCC Statement further details that the equipment has been tested and found to comply with Class B digital device limits, providing reasonable protection against harmful interference in residential installations. In case of interference, the manual suggests corrective measures such as reorienting the receiving antenna, increasing separation between equipment, or consulting a dealer/technician.
A significant portion of the FCC Statement is dedicated to SAR (Specific Absorption Rate) information. This section describes the device as a radio transmitter and receiver, designed to meet emission limits for radiofrequency (RF) energy set by the Federal Communications Commission. The SAR limit set by the FCC is 1.6 W/kg, and the manual provides the highest SAR values for the Infinix X6815B when tested at the ear (1.112W/Kg) and when worn on the body (1.014W/Kg). It clarifies that while SAR values may vary, they all meet government requirements for safe exposure. The maximum scaled SAR in hotspot mode is 1.175W/Kg. This information is vital for user safety and regulatory transparency, assuring users that the device operates within established safety guidelines.
For body-worn operation, the manual specifies a minimum separation distance of 10mm between the user's body and the handset, including the antenna, to comply with RF exposure requirements. It also advises against using third-party belt-clips, holsters, or similar accessories that contain metallic components, as these may not comply with RF exposure requirements. Users are instructed to use only supplied or approved antennas. This guidance is essential for maintaining the device's safety profile during practical use.
Finally, the manual acknowledges DTS patents and states that the device is manufactured under license, indicating the inclusion of DTS audio technology. It also confirms that the operating system is Android™ and that Android is a trademark of Google LLC, providing important software-related information. This comprehensive manual ensures users are well-informed about their Infinix X6815B, from its physical components and operational procedures to critical safety and regulatory compliance details.
