The UR-4E UHF 700 / 800 / 900 MHz receiver is primarily software-controlled, allowing tuning, programming and
maintenance to be done via software service with few hardware adjustments required.
RSS Service Mode:
The RSS has the ability to put a receiver into Service Mode, where the Reference Oscillator may be aligned, Audio
Levels may be set, Jumper Settings may be selected, a BER test can be performed, and an RSSI meter can be
monitored. To put the receiver into Service Mode, it must be connected to a PC running the Radio Service Software
(RSS) using a type A to 5-pin mini-type B USB cable. From the RSS Receiver Confi guration window, click on the
Service button. Note that you must not remove power to the radio or swap radios during servicing. When any
required Service functions have been completed, the radio can be taken out of Service Mode by clicking on the Quit
button in the Service window.
Note: For complete alignment procedures, refer to the instruction manual. These notes are for reference only.
