USB Charging Operation

YU4 features one 5V 1.0 A USB charging port on the back panel. This is a convenient power source to

charge your devices.

When YU4 is in Playback Mode (LED White) and Standby Mode (LED yellow), the port is active, and

whatever device is connected is able to draw up to 1.0 A of power.

Bluetooth

Operation

1. We recommend keeping a maximum distance of 10 meters between the speaker and your device.

The best signal delity is within this range.

2. You can stream audio from your device to the speaker using either the player control buttons of

your device or the control buttons of the remote control (see diagram of Remote Control on page 5

of this manual – buttons #20, #21, and #22).

3. Take note of the following behavior and functionality during Bluetooth operation. When you are

successfully connected, the Blue LED will be lit solid, and your device will show as connected to ‘YU4

by Kanto’.

• The connection between speaker and device remains active even if input source has changed.

For instance, you can switch to another input source (e.g. RCA) and return to Bluetooth

operation without losing signal connection and, therefore, do not need to pair with the device

again.

• When the speaker is put in Standby mode or powered OFF, Bluetooth connection with the

device is lost. When the speaker returns to Playback mode, the Bluetooth connection between

the speaker and device is re-established. However, you may notice a choppy playback signal for

approximately 30 seconds after reconnection. It will normalize.

• While the speaker can be paired with more than one device, only one device can play and

transmit audio signal at a time.

4. The YU4 remote control features a Bluetooth Reset button to quickly disconnect a paired device and

allow a second device to pair with the speaker (button #7 on the Remote Control diagram on page

5).

• Press Bluetooth Reset button to disconnect a paired device.

• Follow the pairing instructions to pair another device.

• The same behavior and functionality apply to the second device.

Bluetooth

Pairing

YU4 features Bluetooth 4.0 with Qualcomm® aptX™ technology and can be paired with many devices

for wireless audio playback from your phone, MP3 player or tablet. Pairing is easy.

1. Press the Bluetooth button ( ) on YU4’s remote to select it as the input source. The Bluetooth LED

(blue) will ash to indicate that YU4 is in pairing mode.

2. Enable your Bluetooth device to search for a new device to pair with. Select ‘YU4 by Kanto’ from the

list of Bluetooth devices available for pairing.

3. If pairing is successful, the Bluetooth LED (blue) will remain solid. You will not need to pair the same

Bluetooth device again - ‘YU4 by Kanto’ will remain on your device list until you remove it from the

list.

4. If the device does not pair with YU4, turn the speaker’s ON/OFF Switch to the OFF position, then

repeat Steps 1 to 3. Alternatively, you can press the Bluetooth reset button ( ) on the remote or

turn o Bluetooth on your device and turn it back on again.
