Introduction
Thank you for choosing the Adastra MG-220 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 the following instructions to gain the best results from your megaphone.
Safety
The MG-220 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 MG-220 operates from 8 x “D” cell batteries. It is advised to use alkaline or NiMH batteries and 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.
Note:
It is important to load the batteries into the rear compartment with the correct polarity.
Failure to do so will result in the megaphone not working and could lead to overheating and
damage to the unit. Please check the diagram in the “Setting up” section below.
This product does not have a recharging circuit, so it is not possible to recharge NiMH batteries
when installed in the unit.
Positioning during operation
When in use, the pistol grip 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.
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.
