infrared microphone/transmitters
The infrared microphone/transmitter is comprised of a microphone input, signal processing
circuits and several emitting diodes that transmit the vocal signal to the sensor.
The microphone/transmitter can be the Sapphire or Handheld. The rechargeable batteries
will provide 6–8 hours of service per charge. Place the microphone/transmitter in the charger
for overnight charge and it will be ready for another day's use.
The drop-in battery chargers are specifically designed to recharge lithium & NiMH batteries
at an optimum rate for maximum operating capacity and extended service life. Charger will
automatically start charging the batteries upon insertion and will shift to a maintenance
charge when batteries are fully charged.

words of caution and limitations of infrared
Be sure that the path of transmission between the emitter and sensor is not obstructed.
The Sapphire pendant transmitter will not function if placed in pocket.
Infrared will not work outdoors in sunlight.
Dark surfaces will not reflect infrared well and can limit distance of transmission.
Rooms larger than 1600 Sq. Ft or have high ceilings can begin to exceed the ultimate
performance of the Quantum II.
If dropouts are experienced in areas, as additional sensor ICS-55 sensor can extend the system
performance.

IRH-35 handheld transmitter
The Handheld Microphone Transmitter (IRH-
35) is most applicable for student use or direct
presentation. It has an "on/off" switch and a
battery level indicator LED; Green=useable charge,
Red=low battery. The transmitter has 10 emitting
diodes: 8 around the bottom of the handle, and 2
toward the top of the handle. The metal housing
provides low handling noise and insures durable
longevity.
