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.

LED

• Channel “A” or “B” select-

able

• 10 high-power emitting 

diodes

• Diodes at top and bottom 

of handle for increased  
Coverage (2 Top aimed 
out, 6 Bottom 360°, 

 

   2 Bottom aimed down)

• 360º IR radiation for as-

sured connectivity

• Two “AA”, Duracell, re-

chargeable NiMH batteries

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.
