AOR, LTD.

Features

 Digital voice communications using existing analog 2 way radios with encryption.

The ARD9900 uses the same au io frequencies (300 Hz ~ 2500 Hz) as microphone

au io to mo ulate the voice signal. This allows you to use an analog ra io as a igital

voice transceiver.

 Digital voice communications in the Single Side Band (SSB) mode.

The automatic frequency clarifier function a justs frequency rift automatically in the

SSB mo e. (Approximately up to +/- 125 Hz).

 Utilizes the ODF ( ulti Carrier odulation) circuit that is effective against ulti-path or

Selective Fading.

 Automatic digital receive

Automatic voice signal etector recognizes the receive signal as analog or igital,

automatically switching to the appropriate mo e.

 Digital Slow Scan TV (SSTV)

 Built-in video-capture function (NTSC or PAL depending on version)

Compresses the signal into our original a aptive JPEG format. Sen an receive

images in the Digital mo e. Built-in vi eo output connector allows viewing the picture on

an external monitor.

 Built–in high grade Vocoder (A BE)

Utilizing high gra e igital voice compression; elivers quality igital voice

communications.

 Built-in FEC error correction

A powerful error correction circuit elivers stable an reliable communications.

 Data communications on the HF band

Data communication is possible on the HF (High frequency) ban s at no extra cost.

(Spee may be limite by regulations in certain juris ictions.)

 Small and compact unit. Easy to operate.

Simply connect the ARD9900 to the microphone jack an the speaker out jack. No

complicate or risky ra io mo ifications are necessary.

 Utilizes a uniquely designed high performance DSP (Digital Signal Processor) engine

 Battery operation for field use.

Information to the Digital Device user

This equipment uses an can generate ra io frequency energy an , if not installe an

use in accor ance with the instructions, may cause harmful interference to ra io

communications. However, there is no guarantee that the interference will not occur in a

particular installation. If this equipment oes cause harmful interference to ra io or

television reception, which can be etermine by turning the equipment off an on, the

user is encourage to try to correct the interference by one or more of the following

measures:

 Reorient or relocate the receiving antenna.

 Increase the separation between the equipment an receiver.

 Connect the equipment to an outlet on a circuit ifferent from that to which the

receiver is connecte .

 Consult the ealer for technical assistance.

Precautions

To prevent fire, personal injury, or unit amage, please observe the following precautions:

 Do not attempt to a just this unit unless instructe to o so by this manual.

 Do not expose the unit to irect sunlight or place the unit close to heating

appliances.

 Do not place the unit in excessively usty, humi , wet areas.

We are not responsible for any amages to the ra io equipment ue to improper settings

or interface.

We are not responsible for any loss of communications ue to an unexpecte change of

propagation or operating environment.

Front Panel

a. Power on/off switch

b. TX switch

There are two (2) functions with this switch.

1. Digital Image Communication mo e

Set the mo e switch to [10101] ( igital mo e). Press this switch to capture

an sen an image.

Note: When the Video Through Function is activated (AVT command is ON),

pressing this switch will enable output of the video signal connected to the Video

Input to also be sent to the video output port, so that you can monitor the

transmitted video image.

Press this switch again to capture and send the image through the radio

equipment. When the Video Through Function is de-activated (AVT command is

OFF), pressing this switch will automatically capture the video image and then

transmit it through the radio equipment.
