COMMISSIONING
Handheld microphone
The portion located under the display consists of an interwoven metal cylinder
and a plastic cap. Do not remove the plastic cap separately. Remove the metal
cylinder together with the cap. After the careful removal of the microphone han
-
dle from below the display, place two size AA (1.5V) alkaline batteries into the
battery compartment observing the marked polarity (the positive end pointing
downwards). Replace the battery compartment cover. The device is turned ON
by a single pressing of the button under the display and turned OFF by a longer
(~2 seconds long) pressing and holding down of the button. The useful life of
alkaline batteries is typically ~10 hours, but this may vary depending on the con
-
ditions of use. On the digital display a battery symbol shows the battery status.
• Replace the batteries when indicated by the battery symbol on the display, or if
operating range is reduced, or transmission becomes noisy. • Batteries can only
be replaced by adults. • Do not use batteries of various brands and/or status to-
gether. • Remove the batteries right away when depleted, or if the device will not
be used for a longer period. • If any fluids have leaked from the batteries, clean
the battery compartment with a dry cloth wearing protective gloves. • Never
open, place into fire or short circuit the batteries. • Never charge non-rechargea
-
ble batteries. Explosion hazard! • Do not use rechargeable battery cells instead
of batteries, as the voltage output and efficiency of these is significantly lower. •
The efficiency of batteries is reduced in cold ambient temperatures, thus more
frequent replacement may be required.
Receiver
Connect the plug of the supplied power adapter into the rear DC socket and then
connect the power adapter to the mains socket. Some domestic appliances can
generate noise in the sound, when connected to the same mains socket (power
supply), or when operated in the vicinity of this device. Connect the 6.3mm di
-
ameter jack (
MIX OUT
rear mixed output) to the 6.3 mm connector of an amplifi
-
er, mixer, active soundbox or Hi-Fi equipment. For professional applications use
the two symmetrical XLR connectors for less noise and longer cable connection.
The appropriate length connection cable is available separately. Finally, set the
two antennas into vertical position.
Switch the device ON using the
POWER
switch located on the left side of the
front panel. The two digital displays light up, which represent the channels of mi
-
crophone “A” (
CH-A
) and “B” (
CH-B
). Controls on the side of each display adjust
the volume of the respective microphone. Set the volume controls to medium
position before switching the device ON. If an external appliance generates
noise during operation, reposition the antennas into a position, where reception
is better. Otherwise, try to select a channel with less noise.
SETTING, PAIRING, FUNCTIONS
Set the volume control of the amplifier to minimum level. After switching on the
receiver and the amplifier, turn on the two microphones as well. After a short
period of time the
MUTE
signal, which is lit during loss of connection, turns off.
Automatic pairing was successful when the
MUTE
signal does not show on the
microphones and the respective (
CH-A
and
CH-B
) displays show the same
frequency. The volume meter instrument flashes beside the
AF
signal when
the microphone detects sound. Slowly set the volume control of the amplifier
to medium position while setting the desired volume level with the two turning
knobs of the receiver unit (
VOL-A
and
VOL-B
).
If connection was not achieved, or it is not clear, change to another frequency.
In order to do so, unwind the lower part of the handle and press the
SET
button
several times to find a noise-free channel. Upon changing the channel, the new
frequency will be immediately and automatically synchronized between the mi
-
crophone and the receiver unit. The currently selected frequency shown on the
displays of the microphone and the receiver unit will again match. During further
use, by a short pressing of the
ON/OFF
button of the microphone, the currently
selected frequency can be displayed for a short period of time and can be mod
-
ified in sequence using the
SET
button. The channel/frequency assignment of
the two microphones varies, thus they can be set to the same channel as well.
Microphone sensitivity can be set using the
VOL +/-
buttons located on the
handle of the two microphones. This is a practical solution for elimination of
any possible pop noise. During the pressing of the volume control buttons level
indications
V1…V5
(Volume 1-5) are shown on the display. When the buttons
are released, the set value is automatically stored.
• NOTICE! For a stable connection and increased operating range find the chan
-
nel which is most ideal for the given situation at the given location. Selection of
a less appropriate channel can result in a reduced operating range.
• Place the devices to be paired in a close vicinity. In case of connection prob-
lems, select another frequency, or turn the microphone and the receiver unit off
and back on again, or reposition the devices.
• The
MUTE
signal of the receiver unit indicates that radio connection was lost,
while the
AF
instrument on the bottom shows the modulation level.
• Walls, nearby electric appliances and moving bodies can disturb reception, or
reduce the operating range. In particular mobile phones, Wi-Fi routers, com-
puters or larger metal objects.
• Several microphone sets can be used in the same area, as long as various
channels are selected for each.
• A volume set too low results in higher noise, while a volume set too high will
result in distorted sound. The volume setting of the amplifier and the micro
-
phone receiver should correspond. Ideal setting also depends on the position
of the microphones.
TIPS
• The antenna of the handheld microphones is located on the bottom. There
-
fore, avoid holding the plastic cap of the microphones as this can suppress
transmission.
• Do not move the microphone in the hands as it modifies the conditions of
reception.
• Frequencies around 800MHz may be noisier if, in the given geographical re
-
gion, it is also used by mobile phone stations.
• Avoid the presence of powered mobile phones, Bluetooth devices, television
sets, computers, Wi-Fi routers or other radio frequency equipment in the sur
-
roundings, as these can disturb reception.
• The receiver unit should be at least 1 m above ground level. Do not mount the
receiver on walls, wall-mounted shelves, as this significantly deteriorates the
conditions of reception.
• If the microphone is positioned in front of or nearby the loudspeaker, pop noise
may be generated, which can damage the loudspeakers. It is best to place
the microphone behind the soundbox. Increase the volume carefully during
commissioning.
TROUBLESHOOTING
If there is no sound reception, or sound reception is noisy, check whether
- connection is according to instructions / - supply voltage is present and bat
-
teries are good / - the cables are undamaged / - amplifier settings are correct
/ - recommended distance was exceeded / - any nearby electric appliances are
causing interference / - antennas are set vertically / - the plastic cap is covered
CLEANING
Before cleaning disconnect power supply by switching the device OFF and re
-
moving the plug from the charger. Use a soft, dry cleaning cloth. Avoid the use
of any aggressive detergents and liquids.
