Main functions

Switching on and off the device

Press and hold the Multifunction (2) button for 2 seconds to turn on the device. You will see that the Function and charge indicator (4) turns on. You will also hear a confirmation sound when switching on the device.

To turn off your device, press and hold the Multifunction (2) button for 2 seconds. You will hear a confirmation sound and the Function and charge indicator (4) will switch off.

Important: press the Reset (7) button to force shutdown.

Charging the battery

When the battery level is below 10%, you will hear a sound to remind you to charge it. Plug the mini USB end of the provided USB cable into the MicroUSB charging port (6) of your Outdoor Box and the other USB end to any device with an USB charging port and 5 V output (PC, USB wall charger, car charger, etc) to charge the battery. The Function and charge indicator (4) turns red and switches off once the charging process has been completed. The charging time is approximately 3 hours.


  • Use a 5 V 2 A AC/DC power adapter.
  • Do not leave your Outdoor Box completely discharged for a long time.

Playback modes

Double-click the Multifunction (2) button to see the different playback modes and select the one that you prefer. A voice will confirm the selected playback mode:

Bluetooth -- FM Radio -- microSD -- Line-in


Once you have selected the playback mode, access the list of available devices on your smartphone or tablet and select your "Outdoor Box". The devices will be connected without codes. Once the connection has been established, you will hear a confirmation sound.

At this point, you will be able to start playback on your smartphone or tablet. The Bluetooth wireless connection's range is up to 10 meters.

Press Next (1) or Back (3) to control playback from the speaker.

Your Outdoor Box saves the last connected device and automatically pairs with it the next time you turn the speaker on.

Click the Multifunction (2) button three times to start a new Bluetooth search and pair your speaker with a different smartphone or tablet.

Call control (hands-free function)

Once the speaker and your smartphone are paired, you will be able to answer incoming calls from the speaker itself.

When receiving a call, the song you are listening to stops and the ringing tone sounds instead. To answer an incoming call you will only have to press the Multifunction (2) button. Press it once again to hang up.

Keep a distance of 30-50 cm from the speaker for a proper voice reception. The microphone is placed behind the front grille.

TWS (True Wireless Stereo)

This option makes it possible to wirelessly pair a second Outdoor Box Dive/ Shower and hear music with twice as much power. This way, you will create a stereo sound system made up of two different channels: left and right.

To do so, switch on both units, select Bluetooth mode and click three times the Multifunction (2) button on one of the units. You will hear a sound confirming that both devices have been successfully synchronized.

From that moment on, you can start Bluetooth playback any time to hear music through both speakers at the same time. The first connected speaker will be fed with the left channel (L) and the other one with the right channel (R).

If you want to disable this function, click the Multifunction (2) button three times. Both devices will be disconnected.

Switch to the next/ previous track and adjust volume from any speaker while TWS mode is enabled. If you turn up the volume of any of the speakers, you will be turning up the volume of both of them at the same time.

Important: This is only possible if Bluetooth mode is enabled. In all other playback modes (microSD, FM radio or line-in) a TWS connection is not possible.

FM radio

Once FM radio mode is enabled, click the Multifuncion (2) button three times to start searching for FM radio stations. The process may take a few minutes. Once the search has been completed, press and hold Next (1) or Back (3) to select the radio station you want to hear from all saved radio stations.

If you place the speaker somewhere else, the device will carry out a new search to obtain a proper radio wave reception.

Your Outdoor Box saves the last selected radio station when you turn it off and on once again.

Important: The battery charging process may interfere with radio signals depending on the AC/DC power adapter used.

MicroSD player

The device plays .mp3 and .wav files from microSD cards (up to 64 GB). The contents play automatically a few seconds after inserting the microSD card.

Playback will resume from the last track you listened if you turn off the speaker or remove the storage unit and then turn it on once again and insert the very same unit.

Press Next (6) or Back (5) to switch to the next or previous track.

The folders and files of your external cards or sticks will be read in chronological order.

Click the Multifunction (2) button three times to move to the next memory card folder.

Auxiliary audio input

Your Outdoor Box also features a Mini jack audio-in (5) to connect your external devices using the provided audio cable.

Important: It is not possible to control music playback from the speaker while using this mode. To control playback functions you will have to use the connected music player.


Press the hidden reset button located inside the Reset (7) hole to force the device to shut down.
