If you have changed the internal jumper for low-voltage battery operation, 
battery voltage must be within the range of 5.6 ~6.5 VDC. DO NOT apply  
12.0V or severe damage will result, and the warranty will be void!  
Note: No low battery voltage detector is built-in the ARD9800.

Interfacing the ARD9800 
 
Connection to a Radio 
 
Before using your ARD9800, you will first need to wire the cable between your radio 
equipment and the ARD9800. 
 
For your convenience, an 8-pin of a microphone connector for the ARD9800 is included.  
You will need to prepare, however, your own microphone connector for your radio 
equipment.

 16  Connection to a Microphone 
 
A speaker microphone is included with your ARD9800.  However, if you wish to use your own  
microphone with the ARD9800, you may do so by wiring your microphone to correlate with the input 
jack of the ARD9800. Below are the pin assignments of the Microphone connector of the ARD9800. 
 
1.      Speaker output  
Monitor output signal is present at this pin. 
2.      BIAS 
Power source for an electlet condenser type of microphone. 
5V DC through 2.2K ohm of resistor

 17    Connection to a Power Supply 
To operate your ARD9800, use a regulated power supply.  
The operating voltage must be within the range of 10.7 ~ 16.0 V DC  (approximately 200mA). 
A DC power cable is also included with the ARD9800.
