Getting Started

Controls and Ports

IMPORTANT: Be sure to read the safety instructions overleaf before proceeding.

Plug In and Charge

Connect the mains adaptor to the speaker and plug into a suitable mains outlet.

  • The battery indicator LEDs will indicate that the battery is being charged.
  • When charging is completed the LEDs will stop flashing. The speaker is ready for use away from the mains supply if needed.
  • The speaker may also be used whilst charging.

Power On

To switch on the speaker, press and release the ON/OFF button (short press).

  • The power indicator will light, a tone will confirm power on, and the Bluetooth LED will flash.
  • The first time the speaker is used the Bluetooth LED will continue to flash.
  • If previously used and paired it will attempt to connect to the previously paired device – see ‘reconnecting bluetooth device’.

Connect Bluetooth

Use Bluetooth settings on your phone / tablet / etc to connect to the speaker.

  • The Bluetooth name is Beacon 310, 320, or 330 in line with the model of your speaker.
  • When connected there is an acknowledgement tone and the Bluetooth LED will stop flashing and remain on.
  • Play audio content from your connected device as you wish.

Volume Control

Control the volume using the speaker or the connected device.

  • Control the volume using the Volume Up or Down buttons on the speaker. You can press and hold the buttons to more rapidly change the volume.
  • The speaker will flash the battery status LEDs to indicate maximum or minimum volume level is reached.

Automatic standby feature

If the audio from your connected device stops then the speaker will shut down automatically to save power.

  • After 10 minutes without audio it will start to flash the power LED.
  • After a further 5 minutes without audio it will turn off.
  • If audio resumes during this time the power saving timer will be cancelled.

Power Off

To turn off the speaker, give a long press on the ON/OFF button.

Bluetooth Reconnection

When the speaker is turned on it will attempt to reconnect to the last used device.

  • If the speaker cannot connect it becomes discoverable and you may connect another device.
  • Alternatively, even when the speaker is already connected, a long press on the Bluetooth button will disconnect the current device and make the speaker discoverable so that a new device may connect.
  • Beacon 330 only – A short press on the Bluetooth button will cause the speaker to reconnect to previously paired devices if they are within range (up to 10 devices in total).

AUX Input

A non-Bluetooth device may be plugged into the speaker using a 3.5mm stereo jack plug (socket at bottom rear).

  • Pushing the plug into the socket automatically switches the speaker to Auxiliary input mode and the Bluetooth LED will change from Blue to White.
  • Removing the 3.5mm plug will revert to Bluetooth operation.

Reset / Reboot Speaker

To reset your speaker use a paper clip to push the reset switch through the pin hole located underneath the speaker.

Battery Life / Charge Time

Playback time (approx):

  • Beacon 310 / 320 – 12 hours
  • Beacon 330 – 15 hours

These figures are only approximate and are very dependent on playback volume, battery age, temperature and charge output usage (Beacon 330).

Battery charge time – approximately 3 hours (Beacon 330 may take longer).

EQ Setting (Beacon 330 only)

The Beacon 330 speaker offers a number of sound profiles.

  • Give a short press on the ON/OFF button to access EQ settings.
  • The EQ LED will light or flash according to the current setting. The current battery status will also be shown.
  • Press the Volume buttons to step through the settings.
  • The sound will change as you step through the options. After a few seconds without button presses the speaker will store the new setting.
  • The stored setting is remembered even if the speaker is switched off.

Stereo Mode (Beacon 330 only)

Two Beacon 330 speakers may be linked to form a stereo pair with one playing the left channel and the other playing the right.

  • Take the speaker that your device is paired with (or the one that you will plug into using the Aux-In socket). This will become the left channel speaker.
  • Switch on that speaker and then press the Stereo Mode button on its base. 
  • Switch on the other speaker. The two speakers should then discover each other and connect.
  • Ideally the speakers should be not more than about 4 metres apart and located in the same room.
  • The volume, EQ and power off functions may be controlled by either speaker and will operate on both.
  • It will be necessary to press ON/OFF buttons on both speakers to turn on a previously connected pair, but they should then reconnect automatically.
  • To cancel stereo mode pairing give a long press on the Stereo Mode button on either speaker while they are connected.
  • When using the auxiliary input both speakers will play in mono.

Device Charging (Beacon 330 only)

The Beacon 330 has a USB type A socket on the back into which the user may plug a charging lead for another device (such as a phone).

USB output 5.0V DC, 1.0A (maximum).

  • The speaker’s battery will be used to charge the connected device.
  • Charging a device from the speaker will shorten the play-time available from the speaker’s battery before it needs charging.
  • The battery in the speaker may not have sufficient capacity in all cases to fully charge the connected device.
