AUX IN OPERATION 

 

Notes:

• 

If you cannot pair the unit with your Bluetooth enabled device, try solving the problem by 
turning the unit power off, then power on, and then starting the pairing process again.

• 

The Bluetooth function of the unit will remain paired unless the paired device goes out of 
range of 30 feet (10 meters). If the broken link is re-established within 20 seconds, the 
SB2145 will reconnect to the current paired device automatically. Otherwise you will need 
to make a manual connection again later.

• 

You may need to turn off the Bluetooth function of the paired external device first before 
making a new link.

• 

Refer to manual of your smartphone or external Bluetooth enabled device for correct 
Bluetooth operation instructions since it may vary from model to model.

• 

If your Bluetooth enabled device does not support A2DP, it will not play the music through 
the SB2145 system even after it is paired and connected successfully.

• 

If you are pairing and connecting your personal computer to the SB2145 using Bluetooth, 
you may need to set the SB2145 as your computer’s default sound device.

RE-LINKING TO A SMARTPHONE OR BLUETOOTH ENABLED DEVICE 

Even if your smartphone or Bluetooth device is already paired with the SB2145 and with both 
Bluetooth functions turned on, they can become unlinked at some point due to intentional 
manual disconnection or undesirable external signal interferences or over-range for more than 
10 seconds. If this happens, the unit will emit two short beeps. You can re-link them and resume 
play by:
1. 

Select “SB2145” from the device list on your smartphone or Bluetooth device. The SB2145 
should re-link to your Bluetooth enabled device within 5 seconds.

2.  Tap the play button of the music player on your Bluetooth enabled device to resume 

playback.

You can play other music sources (iPod, MP3 or other digital audio players) through the speak-
ers of the unit by connecting the AUX IN JACK to your external player’s audio out jack or 
headphone jack.
1.  Plug one end of a 3.5mm audio cable (not included) into the AUX IN JACK and the other 

end of the cable to the headphone jack of your digital audio player.

2. 

Slide the FUNCTION switch to the AUX IN position.

3. 

Turn on and start playing the external device you plugged into the AUX IN JACK.

4.  Slowly adjust both the volume controls of your unit and the external device until you reach 

a comfortable listening level. 

5.  Turn off both the external audio player and this unit after use. Unplug the audio cable from 

AUX IN jack

Notes: 

• 

If you connect the unit to the Line-Out Jack of your external device, you only need to adjust 
the VOLUME CONTROL of your unit. If you connect to the Headphone Jack of your external 
device, you may need to adjust both the volume controls of your external device and the unit 
to obtain the desirable listening level.

• 

Remember to turn off the unit when you have finished listening. Don't forget to switch off the 
power of your external audio device as well.
