Introduction
Thank you for choosing the Adastra L15RC rechargeable megaphone for voice reinforcement. This product
is designed to offer convenient and easy operation for a wide range of portable public-address
requirements. Please read and keep the following instructions to gain the best results from your product.
Safety
The L15RC megaphone can produce high sound pressure levels at close quarters. Please be aware not to
aim the horn flare toward listeners at close proximity, which may risk damage to the listeners’ hearing.
The L15RC operates from a single 18650 Li-ion cell, which can be removed or recharged in situ.
If replacing the battery, please be sure to use an equivalent type and do not attempt to use other types of
batteries or non-rechargeable cells.
Positioning during operation
When in use, the hand grip of the megaphone should be folded out fully and held firmly with the flare
facing toward the audience. Keeping the loop strap around the wrist is advised for added security. If
needed, a shoulder strap may be attached to the 2 eyes moulded into the top of the housing. For
standalone operation, fold the handle in and sit on a stable surface with the flare facing the audience.
In between uses, the megaphone can be placed on a flat surface with the flare facing downward.
Cleaning
The housing is water resistant and can be cleaned with a damp cloth. Do not use detergents or solvents
on the housing and take care not to allow liquids to get inside the housing at the rear or via the battery
compartment.

Setting up
The L15RC is supplied with a single 18650 Li-ion rechargeable battery. Install the battery by unclipping
the cover of the battery compartment on top of the housing and inserting the 18650 cell with the button
+ end facing upward. The cell may arrive with you fully charged but if not, the power LED will not light or
appear dim and the battery will need to be recharged.
A USB to DC plug lead is provided with the L15RC for recharging the battery installed in the unit from any
5V, 1A USB power supply or charger. Connect this lead from the DC jack on the underside of the housing
behind the handle to an appropriate USB power supply.
Alternatively, the 18650 cell may be removed and charged externally using a battery charger that is
specifically designed for this type of cell.
Operation
Make sure that the hand grip is folded out fully and held firmly with the rear panel facing toward the
operator and the flare facing away. For added security, place the loop strap around your wrist.
Press the POWER/MIC button in and after 3 seconds, the power on indicator (2) will light and the
microphone will be activated. Speak into the microphone at approximately 10-20mm distance.
(do not touch the microphone to your mouth as this can cause feedback)
The output level can be adjusted by pressing and holding the volume down or volume up buttons (5, 10)
For continuous messages or alerts, it is possible to record up to 4 minutes of speech and replay in a
continuous loop. To do this, press the REC button (9) and the recording loop indicator (1) will light. Speak
the required message into the microphone. Press REC again when the message is completed.
(if longer than 4 minutes, the recording will stop automatically).
To play the recorded message back, press REPLAY (8). The RL indicator will flash and the message will be
continually repeated until REPLAY is pressed again to stop the loop. The output level can again be
adjusted by pressing and holding the volume down or volume up buttons.

The L15RC also has an inbuilt player for playback of pre-recorded audio tracks in mp3 format stored on
either a USB stick or microSD card. If power is switched on and a USB stick or microSD with mp3 tracks
stored is inserted into the connector at the top of the housing, playback should begin automatically. If
playback doesn’t start automatically, press the PLAY button (4) and/or check that the stored tracks are in
the correct format.
•Press PLAY to play or pause the current track. The PL indicator will flash slowly during playback.
•Press and hold the PLAY button to repeat the current track. The PL indicator will flash quickly.
•Press the Previous/volume down button (5) to go back to the previous track.
•Hold the Previous/volume down button to reduce the output level.
•Press the Next/volume up button (10) to advance to the next track.
•Hold the Next/volume up button to increase the output level.
If both USB stick and microSD card are inserted with mp3 tracks stored, the last one inserted will play
back automatically. To switch between the 2 devices, press the M button (7)
The L15RC also has an inbuilt siren for emergency alerts.
Be aware that this is very loud and do not point directly toward people at close range.
To operate the siren, press the SIREN button (6) and press again to cancel it.
Note: The siren always reverts the output level to full volume and stops any mp3 or loop playback.
When not in use, switch off the power button and place the megaphone face down (flare down) onto a
flat surface. Folding the handle away makes the megaphone more compact for storage or transport.
Remove the battery if not being used for long periods.
