Note:  MIC GND and GND must not
 be connected together in the ARD9800 connector, or 
 RF feedback will result. 
 
o.  SP IN Connector  (3.5 mm mono jack) 
Connect to the radio equipment’s speaker jack.  (Input level: 0.5 V – 5 V p-p) 
 
 
 
 
Note:  The output signal from a radio’s “accessory” connector may not be sufficient to use for 
 this purpose.  Use the transceiver’s “speaker out” jack.  
 
p.  SP OUT Connector (3.5 mm mono jack) 
Connect an external speaker to this jack to disable internal speaker. 
 
 
 
 
q.  DC IN Connector  (EIAJ Type 4) 
Connect to a regulated power supply.  (10.7 ~ 16.0 V DC, Center pin – positive) For lower voltage 
battery operation, set the internal jumper terminal for battery operation, and then connect external 
batteries .   
						

							 11
  
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.

       Place the jumper between 1 – 2  (NOR) for normal operation. 
Change it between 2-3  (BATT) for battery operation. 
 
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: The SP OUT (external speaker output) has priority regardless of the above jumper 
 setting.

In case the microphone output level is too low to drive your radio equipment, 
place the jumper to the 2-3 position.  
                          Refer to Microphone Level Adjustment  at  page 17 for details.

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.

 be connected together in the ARD9800 connector, or RF 
 feedback will result. 
 
  
						

							 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  
3.      GND 
Chassis ground  
4.       TX 
Taking this pin to the ground will enable to transmit. 
(Same operation as the TX switch on the front panel.) 
                                                      5.       D/A 
Taking this pin to the ground will force the ARD9800 to the Digital voice 
communication mode. 
W hen this pin is left open, the operation mode will be set by the mode switch on 
the front panel.  
6.      MIC PTT 
PTT (Push To Talk) input. 
7.      MIC GND 
Microphone ground signal 
8.      MIC IN 
Microphone signal input 
 
  Connection to a PC 
A PC interface cable is included with the ARD9800. 
Parameter settings can be made by using terminal software. 
Refer to Control Commands at  page  23   for details 
  
						

							 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. 
 
                       Color                         Polarity 
                      ======================== 
                        RED                        Positive (+) 
                        BLACK                   Negative ( - ) 
      
Refer to Internal View: Battery operation at  page 12 for details 
   
If you have changed the internal jumper for low-voltage battery operation, 
supplied voltage must be within the range of 5.6 ~ 6.5 VDC. DO NOT apply 
12.0 V or severe damage will result, and the warranty will be void! 
Note: There is no low battery voltage detector built-into the ARD9800. 
. 
Connection to an External Speaker 
If an external speaker is desired, connect it to the SP OUT jack. This will also disable the internal  
speaker. 
 
 
 
 
 
Level Adjustment 
 
Microphone Level  
The microphone level has been properly adjusted at the factory with the provided microphone.  
Therefore, no further adjustment is needed for normal operation. 
 
             If you wish to use your own microphone rather than the included one, you will need to wire your 
                  microphone connector to match the pins of the ARD9800, and then adjust the microphone level as 
             described in the following steps: 
  
						

							 18 
1.  Connect your microphone to the Microphone connector of the ARD9800. 
2.  Turn the [LEV] knob fully counterclockwise. 
3.  Press and hold the PTT switch of the microphone, and speak into microphone normally. 
4.  Slowly turn the [LEV] clockwise until the [OVER] LED flashes occasionally, with the peaks of 
 your voice signal. 
 
 Radio Input Level 
     
Perform the following steps to adjust the radio input level of your radio equipment: 
 
1.   Connect the microphone to the ARD9800, and then connect the ARD9800 to your radio  
 equipment. Finally, Connect the ARD9800 to a power supply. 
2.  Turn the output level adjustment on the bottom of the ARD9800 fully counterclockwise. Turn  
the power on to the ARD9800.   Turn the power on to your radio equipment. 
3.  Set the mode switch to the Digital mode [10101]. 
4.      Press the  [PTT] switch to transmit from the radio equipment. 
5.     Adjust the microphone gain of the radio equipment until the ALC function just activates. 
6.      If the microphone gain is too low, readjust the output level on the bottom of the ARD9800. 
      
Microphone Balance 
           
If the output level of analog voice and digital voice are not equal, an adjustment can be made. To 
                        adjust the audio balance, perform the following steps: 
 
1.  First, set the proper microphone level in the digital voice mode. 
2.  Turn off the power to the ARD9800.  Press and hold the TX switch then turn the power back 
 on. The MODE LED should be blinking orange, indicating the ARD9800 is in the 
 microphone balance adjustment mode. 
3.  Holding the PTT switch, and while speaking into the microphone, adjust the microphone 
level. 
4.  After the adjustment is completed, push the TX switch to save the new setting. The STA LED 
 will light to indicate the setting process is completed. 
5.      To complete the operation, turn the power of the ARD9800 off, and then turn back it on.

Operations 
 
Note: All adjustments must be properly performed before operation. 
 
Voice Communication 
Your ARD9800 is capable of Digital Voice Communications and Analog Voice Communication. 
In the receive mode, the ARD9800 will automatically recognize the type of communication, and set the 
appropriate operation mode. 
In the transmit mode, the operation mode can be selected by using the front Mode switch. 
 
Digital Voice Communication 
            Set the mode switch  [10101 - ~] upward to the digital mode position.  [10101] 
Press and hold the PTT switch of the microphone.  The STA (Status) LED will flash for about 0ne (1) 
second while sending a data header signal. 
W hen the LED stops flashing, speak into the microphone normally. 
 
      
Analog Voice Communication 
             Set the mode switch  [10101 -  ~ ]  downward to the analog mode position.  [~] Press and hold the PTT 
switch of the microphone, and speak into the microphone normally. 
 
Data Communication 
 
Run a terminal software program to control the ARD9800, and to enter control commands. 
                      
Refer to Control Commands at  page  23 for details 
                            
Two different types of data, ASCII data or binary data, can be used. 
Both data can be mixed as communication data. 
 
    Receive 
Enter the command [ACO] to go into the converse mode. 
The received valid data will be decoded and displayed on the PC screen. 
 
If received data is missing, (which may occur during poor propagation conditions) “garbage” data 
may be displayed on the PC screen.
