The Poly Sync 40 Series Bluetooth Speakerphone is a versatile and portable audio device designed for both mobile and corded connectivity, offering a seamless experience for calls and media streaming. This user guide outlines its setup, daily use, maintenance, and troubleshooting, ensuring users can maximize its features.
The Poly Sync 40 Series speakerphone serves as a high-fidelity audio solution for personal and professional use. It connects to computers via a combined USB-A and USB-C cable for corded operation and to mobile devices via Bluetooth for wireless convenience. The device is equipped with a range of controls, including dedicated buttons for Bluetooth pairing, volume adjustment, call management (answer/end, mute/unmute), and a special button for interacting with Microsoft Teams (on Teams models, requiring a desktop application). Additionally, it features a USB phone charge port, allowing users to power their mobile devices directly from the speakerphone. For enhanced audio experiences, two Poly Sync speakerphones can be linked together for daisy chain audio, enabling stereo sound or a party mode for larger gatherings. The speakerphone is designed to be intuitive, with LED indicators providing clear visual feedback on its status, such as pairing mode, connection status, call activity, mute status, and battery level.
Upon first use, the speakerphone needs to be activated by connecting its USB cable to a power source, which brings it out of a deep sleep mode designed to conserve battery. For corded setup, simply connect the USB cable to a computer, and the speakerphone powers on automatically. Mobile setup involves pressing the Bluetooth button for two seconds to enter pairing mode, then selecting "Poly Sync 40" from the mobile device's Bluetooth settings. A "pairing successful" audio prompt and a solid blue LED confirm the connection.
The device offers a "Secure Connection" feature for mobile use, particularly useful in conference room settings. When enabled via the Poly Lens Desktop App, this feature automatically disconnects the paired mobile device after each call, preventing unintended audio playback through the speakerphone. To re-establish the connection, users can press any button within 30 seconds after a call ends.
For models with a USB Bluetooth adapter (Poly Sync 40+), the adapter comes pre-paired to the speakerphone. Users simply insert the adapter into their computer, and the speakerphone connects automatically, indicated by a solid blue LED and an "PC connected" audio prompt. The adapter can be configured for music playback through computer sound settings (Windows or Mac) and can be re-paired if disconnected or purchased separately, typically requiring the Poly Lens Desktop App.
Daily operation is straightforward. The power button turns the device on or off with a two-second press. Calls are answered or ended with the dedicated call button. During a call, the mute button toggles the microphone mute status, and volume buttons adjust the audio level. The speakerphone also supports voice assistants (Siri, Google Assistant, Cortana) by pressing and holding the call button for two seconds. Teams models have a dedicated Teams button to quickly launch the Microsoft Teams desktop app or view notifications when connected via the USB adapter.
A customizable "Rocket" button allows users to assign various functions, such as play/pause media (default), device status check, clearing the trusted device list, activating the default voice assistant for mobile calls, redialing, or holding/resuming a call.
The daisy chain audio feature allows two Poly Sync speakerphones (Sync 40 and Sync 60 models are compatible) to be linked wirelessly. This is achieved by pressing both link buttons on both speakerphones for two seconds. Once linked, the system can be controlled from either speakerphone, and audio output can be configured for "Party" (default) or "Stereo" mode via the Poly Lens Desktop App. In Stereo mode, the primary device handles the right channel, and the secondary device handles the left.
Battery management is a key aspect of the Poly Sync 40 Series. Users can check the battery status by tapping the power button (for an audio prompt) or any button (to view the LED bar) when the speakerphone is inactive. The LED bar provides visual cues: a long white bar indicates a full battery, a medium white bar indicates high, a short white bar indicates medium, a solid red bar indicates low, and red flashes indicate a critical battery level. LEDs do not illuminate in standby mode.
Charging the speakerphone is done via its USB cable, connected to a computer or a wall charger. The LED bar pulses during charging and turns solid white when fully charged, with a full charge taking approximately 5 hours. For faster charging, a wall charger or a computer's quick-charge USB port is recommended. The speakerphone's combined USB-A and USB-C cable ensures compatibility with various ports.
The speakerphone can also charge a mobile phone by connecting the phone's charge cable to the speakerphone's USB-A port, provided the speakerphone's battery level is medium or higher. This connection only provides power.
Software and firmware updates are crucial for optimal performance and access to new features. Users are encouraged to keep their Poly device up-to-date using the Poly Lens Desktop App, which can be downloaded from poly.com/lens. This app also allows for customization of device behavior through advanced settings and options, including call control functionalities for certain softphones. The Plantronics Hub Desktop App also provides access to device settings.
Troubleshooting guidance is provided for common issues, such as the speakerphone not powering on (due to deep sleep mode), slow charging (suggesting a quick-charge port), or interaction problems with Microsoft Teams (ensuring it's a Teams model and using the desktop app). Solutions for stereo sound availability in daisy chain mode and the use of the Secure Connection feature are also detailed, emphasizing the role of the Poly Lens Desktop App for configuration.
