5. Toimintatilat

The VIKEFON BTB002BL supports three distinct operating modes: Transmitter (TX), Receiver (RX), and Bypass.

5.1. Lähetintila (TX)

In TX mode, the adapter transmits audio wirelessly from a non-Bluetooth device (e.g., TV, PC, iPod) to Bluetooth-enabled headphones or speakers.

1. Slide the Mode Switch to 'TX'.
2. Connect the adapter's TX Input to your audio source (TV, PC) using the appropriate cable (Optical or 3.5mm AUX).
3. Varmista, että Bluetooth-kuulokkeesi/kaiuttimesi ovat pariliitostilassa.
4. The adapter will automatically search for and connect to nearby Bluetooth devices. The TX LED will illuminate, and the codec LED (HD, LL, or SBC) will indicate the active audio codec.

5.2. Vastaanotin (RX) -tila

In RX mode, the adapter receives audio wirelessly from a Bluetooth-enabled device (e.g., smartphone, tablet) and outputs it to a non-Bluetooth audio system (e.g., wired speakers, home stereo).

1. Slide the Mode Switch to 'RX'.
2. Connect the adapter's RX Output to your audio system (speakers, amplifier) using the appropriate cable (Optical, 3.5mm AUX, or RCA).
3. Enable Bluetooth on your smartphone or tablet and search for 'VIKEFON BTB002BL'.
4. Select the device to pair. The RX LED will illuminate, and the codec LED will indicate the active audio codec.

5.3. Bypass Mode (Wired Connection)

Bypass mode allows for a direct wired connection between your audio source and output device, bypassing the Bluetooth functionality. This is useful when Bluetooth is not needed or when you want to quickly switch between wired and wireless without re-cabling.

1. Slide the Mode Switch to 'BYPASS'.
2. Connect your audio source (e.g., TV) to the adapter's TX Input.
3. Connect your audio output device (e.g., soundbar, wired speakers) to the adapter's RX Output.
4. Audio will pass through the adapter directly.

Refer to Image 5.2 for a visual representation of Bypass Mode, showing a TV connected to a soundbar via the adapter.

6. Pariliitos ja yhteys

6.1. Bluetooth-pariliitos

Parin muodostaminen uuden laitteen kanssa:

2. Ota NFC käyttöön älypuhelimellasi.
3. Tap your smartphone near the NFC logo on the adapter.
4. Vahvista pariliitospyyntö älypuhelimellasi.

6.3. Dual Stream (TX Mode) / Multi-Point (RX Mode)

The device supports connecting to two Bluetooth devices simultaneously:

• TX Mode (Dual Stream): After pairing with the first Bluetooth headphone/speaker, put the second device into pairing mode and press the 'Quick Pairing' button on the adapter again. The adapter will connect to both devices, allowing two users to listen to the same audio source.
• RX Mode (Multi-Point): The adapter can connect to two smartphones simultaneously. After connecting the first phone, connect the second phone. You can then switch between audio sources from either phone.

7. Audio Codecs

The VIKEFON BTB002BL supports several audio codecs, indicated by the LEDs on the device:

• aptX-HD: Provides high-definition audio quality, offering a superior listening experience. For aptX HD to be active, both the adapter and the connected Bluetooth device must support aptX HD.
• aptX Low Latency (aptX LL): Minimizes audio delay, ensuring perfect synchronization between video and audio, ideal for watching TV or movies. Both devices must support aptX LL for this codec to be active.
• SBC: The standard Bluetooth audio codec, offering basic audio quality. This codec will be used if aptX HD or aptX LL are not supported by both connected devices.
