This document outlines the operation and maintenance of the Shenzhen tSmart Electronic Co.,Ltd True Wireless Stereo Earbuds, model HF-BTSX1TWS-BK (FCC ID: 2ATP7-BTSX1). These earbuds are designed for a seamless audio experience, offering both stereo and mono modes for versatile use.

Function Description

The earbuds are primarily designed for audio playback and phone calls. They utilize Bluetooth® 5.0 technology for wireless connectivity, ensuring a stable and efficient connection to your device. The multifunction button (MFB) on each earbud serves as the primary control interface for various functions.

In Music Mode, a single press of the MFB allows you to play or pause your audio. To skip to the next song, press and hold the MFB for 3 seconds until you hear a click voice. This intuitive control scheme allows for easy management of your music without needing to access your connected device directly.

For Phone Talking Mode, the MFB provides comprehensive call management. A single press will answer or hang up a call, making it convenient to manage incoming and ongoing conversations. If you wish to reject an incoming call, press and hold the MFB for 2 seconds. Additionally, a double press of the MFB will call back the last dialed phone number, offering quick access to recent contacts.

The earbuds support two primary connection modes: Stereo Mode and Mono Mode.

In Stereo Mode, both earbuds are used together to provide a rich, immersive stereo sound experience. To initiate Stereo Mode, simply take both earbuds out of their charging case. They will automatically power on and connect to each other. Once connected, activate Bluetooth® on your phone and search for "BTSX1" to pair. A notable feature of Stereo Mode is its flexibility: if one earbud is placed back into the charging case, the other will continue to function independently. Should you remove the first earbud from the case again, it will automatically reconnect to the other, seamlessly restoring the stereo experience.

Mono Mode allows you to use a single earbud independently, which can be useful for awareness of your surroundings or extending battery life by alternating earbuds. To use Mono Mode, take either earbud out of the charging case. It will automatically power on and enter pairing mode. Then, activate Bluetooth® on your phone and connect to "BTSX1".

A key convenience feature is the automatic reconnection capability. After the initial successful connection, the earbuds will automatically connect to your phone in future uses, regardless of whether you are using mono or stereo mode, simplifying the user experience.

Usage Features

The earbuds are designed for ease of use from the moment you take them out of the box. Power management is largely automated. When you place the earbuds into the charging case, they will automatically power off and begin recharging. The charging case itself is intelligent, detecting when the earbuds' battery is full and stopping the recharging process to prevent overcharging.

During the charging process for the earbuds, an LED indicator on the earbud will glow red. Once fully charged, this LED will turn blue and then switch off, providing a clear visual cue of their charging status. For the charging case, its LED will flash red while it is being charged. When the charging case is fully charged, its LED will turn blue.

Maintenance Features

The manual provides guidance on troubleshooting common issues to ensure the longevity and optimal performance of your earbuds.

One common issue addressed is sound cutting out. The manual explains that this can occasionally occur in environments with strong Bluetooth® or Wi-Fi interference and is considered normal behavior for wireless devices.

Another important maintenance point is earbuds not recharging. If this happens, the first step is to check if the charging case itself has sufficient battery. If the charging case battery is depleted, it needs to be charged first. If the charging case battery is normal, the issue might be due to dust or sweat accumulating on the charging pins inside the case or on the earbuds themselves after prolonged use. In such cases, cleaning the charging pins is recommended to restore proper contact and charging functionality.

To check the charging status of an earbud, simply open the charging case cover. If the earbud's LED is red, it indicates that it is currently charging. You can also observe the LED on the charging case: if it is flashing red, it signifies that an earbud inside is charging.

The product overview highlights key physical components:

Power charging touch point: This is where the earbuds make contact with the charging case for power transfer.
MFB/Indicator light: The multifunction button also integrates an LED light to indicate status (e.g., charging, pairing).
Headset speaker: The component responsible for audio output.
Power charging 'indicator light: An LED on the charging case to indicate its charging status.
USB charging port: The port on the charging case used to recharge the case itself.

The manual also includes a 90-day limited warranty, advising users to return defective products with proof of purchase for repair or replacement. This ensures support for any manufacturing defects within the specified period.

Finally, the device complies with FCC regulations, ensuring it meets standards for electromagnetic interference and safe operation. Users are advised that any unauthorized modifications could void their authority to operate the equipment.
