Introduction
Thank you for choosing the Adastra L01 portable megaphone for voice reinforcement.
This product is designed to offer convenient and easy operation for a wide range of portable public
address requirements. Please use these instructions to gain the best results from your L01 megaphone.
Safety
The L01 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 L01 operates from 4 x “C” cell batteries. It is advised to use alkaline or NiMH batteries and remove
these when not in use for long periods of time. Some batteries can leak fluids which are corrosive and can
cause damage to the internal circuitry.
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. In
between uses, the megaphone can be placed on a flat surface with the flare facing downward, protected
by the rubber trim around the flare edge.
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
Before operating the L01 megaphone, it will be necessary to load it with 4 x “C” cell batteries.
To access the rear battery compartment, press the battery compartment release button (5) and the rear
section of the megaphone will flip upwards to reveal the battery holder.
Load in the C cell batteries with alternate polarities as shown in the diagram below. Note the imprinted
“+” and “-” symbols inside the compartment and ensure that the correct polarities are observed.
Fold down the rear section to cover the battery compartment until it clicks firmly shut.

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 the wrist.
Adjust the volume control slider (3) to the centre of its travel and slide the Speech / Off / Siren switch (4)
to the “Speech” position - the LED indicator (2) will light to show that the megaphone is activated. Speak
into the microphone (1) and adjust the volume slider up or down to suit the output level required.
When speech is finished, move the switch to the “Off” position, which also preserves the battery.
If an alert is required, moving this switch to the “Siren” position will emit a loud sweeping pitch from the
horn. Switching to “Off” again stops the siren.
When not in use, 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 batteries if not being
used for long periods.
