Caution:
Please read this manual carefully before operating Damage caused by misuse is
not covered by the warranty
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.
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.
Controls
- Trigger switch
- Siren switch
- Push to talk switch (with lock)
- Microphone
- Volume control edge roller
Setting up
Before operating the MG-220 megaphone, it will be necessary to load it with 8
x “D” cell batteries.
To access the rear battery compartment, release the lever clip at the top and
allow the rear cover to fold down.
Load the battery holders with 8 x “D” cell batteries with alternating
polarities as shown below.
Polarity symbols are imprinted on the inside of the rear cover to help with
this.
Alternatively, the MG-220 can be powered by an external 12Vdc source
(such as car battery) connected via a 2.1mm DC jack located between the pistol
grip and rear cover hinge. This jack is covered with a rubber plug for
protection.
The image on the left shows the underside of the rear of the megaphone.
Operation
The pistol grip should be held firmly in one hand with the rear panel facing
toward the operator and the flare facing away. Alternatively, the megaphone
can be slung under the arm using the supplied shoulder strap.
Holding the microphone in the other hand and pressing in the push-to-talk
button (3) will activate the microphone. If the push-to-talk button cannot be
pressed in, it may be locked. Slide this button down to unlock and press in to
talk.
Set the volume control edge roller (5) to the centre of its travel and speak
into the microphone (4). Adjust the volume control to the required volume
level.
Alternatively, the microphone may be hooked onto the rear cover for single
handed operation.
Pressing the trigger switch (1) activates the microphone.
There is also a siren function which emits a loud sweeping tone for warnings
or alerts.
To activate this, slide the siren switch (2) on the rear of the pistol grip to
the SIREN position.
Sliding it back to the TALK position cancels the siren.
Remove batteries if not being used for long periods of time.
