Audio Output Connection
There are two audio outputs on the back of the receiver, Mic-level balanced and Line-level
unbalanced. Use audio cable for the connection between the receiver and the amplifier/mixer.
 Unbalanced Audio Connection: If the amplifier/mixer has a 6.3mm φ phone jack, connect a
cable from the 6.3mm unbalanced audio output from the receiver to the amplifier/mixer.
 Balanced Audio Connection: If the amplifier/mixer has an XLR input, connect a cable from
the balanced XLR audio output from the receiver to the amplifier/mixer input.

Rack Mounting (Optional Kit)
The receiver can be cabinet-mounted by either one or two units as optional extras. If only one
receiver is to be mounted, an RMK-33 kit is available. It's installed as shown in Fig 1. If two
receivers are to be mounted, they can be assembled by an RMK-22 kit and installed as shown
in Fig 2.

Battery Type Setting
Alkaline or Rechargeable can be used with our transmitter. Our optional Battery Charger HC-24
can be used for both types of transmitters.
1. Press-release MENU button until the
CHANNEL-BATTERY TYPE page appears.
2. Press and hold SET button until NIMH or
AKLN flashes to denote readiness for
setting.
► ►
3. Press-release SET or MENU button to
select either NiMH (rechargeable battery) or
AKLN (alkaline battery).
4. After a battery type is chosen, wait about 3
seconds to store the setting.
►
Important: NiMH battery must be selected when rechargeable battery is being used. Never
select AKLN (alkaline) when a transmitter is intended for re charging as alkaline batteries are
not rechargeable. Wrong battery selection will result in battery sensing electronics to display
wrong and misleading status information. Recharging Alkaline Batteries is dangerous will lead
to damage of the transmitter & charger and will void all warranties. Alkaline and Rechargeable
batteries cannot be mixed.
GAIN setting (GT｜MT) for Controlling Device Sensitivity
Gain control enables the user to set different sensitivity levels (+/-) for the
device plugged into the transmitter – This allows more/less adjustment at
the mixer level.
GT is for the use of instrument with high impedance, such as guitar.
MT is for the use of low impedance such as lapel or headset microphones.
RF Power Setting
Important: Lower output power will reduce the RF transmission distance and higher output
power will extend the possible RF transmission distance. However, higher output power places
slightly more load on the battery and will reduce operating duration faster than lower output
power. Factory Setting is 10db.

Operation
1. Connect the adaptor to a wall outlet.
2. Insert the transmitter onto the charger.
3. Indicator LED: Solid red during charging. Solid Green when fully charged. Charging process
takes about 5 hours. (Using battery 1.2V 2100mAH. Transmitter refers to indicator.)
4. The power sharing allows series connection for simultaneous charging of max 6 transmitters.
Both chargers’ power status can be read by individual indicator③ or ④ on the master unit,
which turns on if connected. Connect up to 3 bases to one power supply.
5. This charger adopts intelligent compensation charging/control circuit for output-short
prevention and user-friendly operation.
Note
If the red LED doesn't light up or keeps flashing during the charging process, it indicates the
charging contacts error, the battery quality is poor, or has an output short. Please reposition the
transmitter or replace the batteries with new ones and ensure the correct connection between
the charger and transmitter and then restart the charging process.

This microphone requires 2 x AA batteries to operate. To install, remove the battery cover and
slide the batteries into the battery compartment & replace the battery cover.
When the microphone is switched ON, a blue LED will blink once to denote the batteries
installed are in good condition. If the LED remains illuminated, it means the batteries are
weak and require replacement.
Note: Batteries contain a corrosive acid that may leak and damage the microphone
when stored for a long period. Batteries should be removed from the microphone
before storing without use for more than 4 weeks.
