Preparing the Radio Microphone for use
The 1810 Handheld Radio Microphone incorporates a transmitter
powered by a 9 volt PP3 type battery (supplied).
1 Prior to fitting the battery
ensure that, if fitted, the small
rubber insulating cap has been
removed from the positive (+)
terminal of the battery.
2 To fit the battery, twist the micro-
phone collar in the direction
indicated by Arrow 1 (shown
above).
Carefully pull the
microphone body
down (see arrow
2, above) to
reveal the bat-
tery chamber.
3 Fit the battery, noting the
correct location of the battery
terminals.
Push the body back up into
the closed position and twist
the collar to lock the body in place.
Switching on the Radio Microphone
A switch is located at the base of the radio microphone.
With the switch
pushed to the
RIGHT, the radio
microphone is
switched OFF. Push
the switch to the
LEFT to turn the
radio mic ON.
A red LED glows near the switch to indicate that the microphone
is switched on. If the light does not glow, check the condition of
the microphone battery and replace it if necessary.
The Radio Microphone is now ready for use.
Checking the Frequency of the Radio Mic
A label fitted inside the battery
compartment lists the frequency
range of the radio microphone.
Ensure that the radio microphone
frequency is the same as the
receiver. If necessary, check
that the channel selector
found in the body
of the microphone
has not been
set to a new
frequency.
New microphones will be set to
channel 1 unless supplied with a
Coomber Radio Mic PA system. In this
case the microphone(s) will match the
receiver units installed.
Useable Distance
Outside: In ideal conditions the radio microphone will operate
up to 50 metres from the receiver. Note obstructions, (such as metal
objects, vehicles, scaffolding etc) between the microphone and
the receiver will impede performance.
Indoors: Building structure can affect performance. Dense material,
particularly steel beams, can interfere with the signal, so it will be
worth experimenting to get the best results by positioning the receiver
at a location most “visible” to the microphone user.
Note: Two radio microphones of the same frequency will not operate
together - one will cancel the other out. With this is mind, please
inform us of the frequency of your existing radio microphone
should you wish to order a second radio microphone system.
