POWER Switch/POWER Indicator:

 

   This switch is used to turn the  
   880iR ON (switch up), or OFF 
   (switch down). When the POWER 
   switch is in the ON position, the 
   POWER light will glow red.

2. IR Indicators (IR):

 These lights will 

  glow red when the corresponding 
  microphone is turned on. This light 
  confirms the 880iR is receiving a 
  steady infrared signal.

AF Indicators (AF):

 These lights 

  flash green when audio (voice) 
  from the microphone is detected.

4. A VOLUME:

 Controls the volume 

  level of the teacher microphone 
  that is switched to Channel A.  
  Rotating the knob clockwise  
  increases output level.

5. B VOLUME:

 Controls the volume 

  level of the optional second  
  microphone that is switched to 
  Channel B. Rotating the knob  
  clockwise increases output level.

Speak 

in a natural voice. A normal conversational speech level 

will provide an adequate signal. It is not necessary to increase  
the intensity of your voice—the amplification system provides  
adequate amplification (approximately 5 – 10 dB) above  
ambient room noises.

TIPS ON CLASSROOM AMPLIFICATION

Avoid

 wearing jewelry that may rub or bump against  

the microphone.

Turn

 the LightMic off during private conversations with a student,  

parent, or other classroom visitor. You can also cover the LED  
lens on top of the LightMic to block the signal.

 Recharge

 batteries each night. When recharged nightly, operating  

 time (actual usage) for the transmitters will last through a typical     
 school day.

Our Service Department (800.732.8999, 6:30 a.m. – 5 p.m., 

PST) will handle all your repair/replacement needs.
