Introduction
Thank you for choosing the Adastra L50U megaphone with USB/SD player. This product is designed to
offer convenient and easy operation for a wide range of portable public address requirements. Please use
the following instructions to gain the best results from your megaphone.
Safety
The L50U gaphone can produce high sound pressure levels at close quarters. Please be aware not to me
aim the horn flare toward listeners at close proximity, which may risk damage to the listeners’ hearing.
The L50U operates from D batteries. It is advised to use alkaline or NiMH batteries and 10 x “ ” cell to
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 handle of the megaphone should be held firmly with the flare facing toward the
audience. Alternatively, the megaphone can be slung under the arm using the supplied shoulder strap or
free-standing on a flat surface An M8 threaded insert is also provided for mounting onto a plate or stand. .
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 or the battery compartment.
Setting up
Before operating the L50U megaphone, it
will be necessary to load it with 10 x “D”
cell batteries. Alternatively, a 12Vdc
supply can be connected to the 12Vdc
input on the side panel.
To access the rear battery compartment,
press down the latch at the rear of the
housing marked “PUSH OPEN” and allow
the rear cover to fold down. Remove the
plastic insert from the battery
compartment and load 2 batteries into
each of the 5 cylinders as shown in the
diagram. Replace the insert and close the
cover.
Note: the pairs of batteries are loaded
with alternate polarity as imprinted on the
outside of the insert.
