1 Introduction

1-1 Introduction
Thank you for purchasing the ARD25 Multimode Data receiver.
In recent years, many communications have changed from analog mode to digital mode to meet
more communication demands. APCO Project 25, as an example, has been adopted by many
public safety or police departments in several major cities.
The ARD25 is designed to convert conventional APCO25 (P25) digital communications to analog
signals.
To get the best possible results, we recommend that you read this manual to fully familiarize
yourself with the ARD25.
Every effort has been made to make this manual correct and up to date. Due to continuous
development of the product (and by error or omission), anomalies may be found and this is
acknowledged.

Some words of caution – The ARD25 is not effective on systems that use encryption or digital
modulation other than APCO Project 25. It cannot translate signals from receivers that do not
have a 10.7 MHz IF output, as the full channel bandwidth is needed to convert the signal from
digital to analog. The ARD25 does not add trunking capabilities to your receiver. Some
jurisdictions may limit the use of devices such as the ARD25.
