2.  Plug the 3.5mm stereo plug into the audio input jack of the recording device.           

3.  If it is to be used, plug in the in-car microphone into the In-Car Mic jack in the side of the 

receiver base.  

4.  Turn on the transmitter and place it in the charging cradle with the beltclip facing out.  

The Charge LED will light if there is power.  If the LEDs do not come on, check the 
connections and repeat.  

Installation is complete.  Refer to Operation Section for more information.      

 

4) Guidelines and recommendations for best performance.  

Compatibility 
The transmitter and receiver must synchronize to work together (see Synch process on page 3).  
The synch operation only needs to be performed the first time a system is used, or when a new 
bodypack is used with a base previously synched to another bodypack.  Do not synch multiple 
times, just once until a new bodypack is used.
  Any PR24ND can be synchronized with any 
PB24N or PB24ND.  

Using Multiple Wireless Systems 
The PW24ND system has 95 possible  channels  that are really different frequency hopping 
schemes.  Each synchronized base and transmitter will automatically find a clear channel so up 
to 40 systems can work together in one location depending on other interference problems.  

Potential Sources of Interference 
There are many potential sources of interference for your wireless system.  Any electronic 
product that contains digital circuitry including digital signal processors (reverb/multi-effects units), 
electronic keyboards, digital lighting controllers, CD and DVD players, and computers, all emit RF 
energy that can adversely affect the performance of your wireless system.  It is always best to 
place the receiver as far away as possible from these devices to minimize potential problems.  

The PW24ND operates in the 2.4MHz ISM band and other devices in that band may interfere.  
The spread spectrum technique used in the PW24N is very robust and should operate even in the 
presence of other 2.4MHz devices such as walkie-talkies, LANs, cordless phones, etc. in the 
area.    

Battery Recommendations 
The Lithium-Ion battery built into the PB24N transmitter will work at full capacity for over 500 
charge cycles.  If you notice lower than usual battery life over time, it may be time to replace the 
cell.
