The overall system is a combination of a receiver and a wireless microphone. The
combination for R-1000 or R-2000 could be selected as the following.
BASIC COMBINATION SYSTEM
R-1000 / R-2000 matches Q-1000
M-1000
BASIC COMBINATION SYSTEM
When two or more wireless microphone are used
carriers must be different from
the others in order to avoid mutual interference.
To make sure that the system performs correctly
please place the receiver at
least 1 meter above the ground and at least 1 meter away from concrete walls or
metal surfaces to prevent any reflection. The microphone should also be at least
1 meter away from the receiving antenna
as shown in Fig. 5.

INSTALLATION OF THE SYSTEM
OPERATION INSTRUCTIONS OF OVERALL SYSTEM
1. Turn volume control of the receiver as well as the mixer or the equipment to be
used to the minimum
then switch on the receiver. The pilot LED of the
receiver will light up
and the AF signal indicator will give a flash.
2. When a transmitter is switched on
RF signal indicator LED of the receiver
will light up indicating that the system is in normal operation. When indicator
LED of the receiver does not light up
indicating that the system does not
match
both of the transmitter and the receiver should be checked whether they
are in normal operation or not.
3. When a matching transmitter is switched on at distance within 15 meters away
from a receiver
RF signal indicator LED of the receiver does not light up
indicating that the system is matched but is in abnormal operation.
4. When sound is applied to the microphone while the system is switched on and
is in normal operation
AF signal indicator will light up accordingly
indica-
ting that audio output of the system is in normal operation.
5. AF output level can be adjusted by volume adjustor to match the maximum
input level of the equipment to be used.
6. Audio output level must be adjusted to match a proper input level of the mixer
or the equipment to be used. If output of the receiver is adjusted too high and
volume control of the mixer is turned too low, it will cause the mixer output to be
distorted. Conversely
the mixer output will not be distorted
but a poor S/N
ratio will be caused.
7. After proper adjusting the output volume of the system
adjust volume control
of the mixer or the equipment to be used to get a desired sound level output of
the microphone.
8. Power supply voltage can vary from 12-15V DC

CAUTION
1.Since use of an antenna extremely influences efficiency of the wireless microphone
system, proper selection and set-up are necessary. The shorter the better is the
most important rule to keep distance between the microphone and the receiiving
antenna.
2.In case of multi-channel operation, proper selection of non-interference channels is
of utmost importance.
3.Remove batteries out of the microphone if the unit is not to be used for a long period.
4.Tuned circuits and variable resistors & capacitors inside the transmitter and the
receiver have been precisely adjusted, please do not make any adjustment.
Otherwise, normal operation will be interrupted.
