TURN
on the transmitter (green LED will indicate power, red LED
indicates that batteries need to be recharged).
POWER on the amplifier (red LED will indicate power; green LED

TRANSMITTER/MICROPHONE needs to be worn in a way as to
have a clear path to the receiving sensors.
POSITION the transmitter/microphone six inches from your
mouth.
RELAX and speak at a comfortable level. Remember, you do not
have to project your voice.
CHARGE
the batteries every day. Ni-MH batteries will last for 6-8
hours of continuous use. Recharge for at least 12 hours
(overnight). (Ni-MH-Batteries need to be replaced annually.)
HAVE ANOTHER PERSON MONITOR your amplified voice from
time to time to make sure it is not too loud.
