ImmersionRC | EzUHF JR Module Manual Supplement

Introduction

Congratulations on your purchase of an ImmersionRC EzUHF ‘JR’ module transmitter.

This manual is a supplement to the general EzUHF Control System, Overview & Operating Instructions

manual, which may be downloaded from the ImmersionRC Website, and gives more general information

on the EzUHF system.

with a more convenient form-factor, and much simpler cabling.

Specifications

 Output Power 500mW (high), 200mW (low)

 DC Power Input 6v – 13v

 Current Consumption 250mA @ 12V in high power mode, 85mA @ 12V in low power

 Head-tracker Power Same as input voltage

 Channel Count Currently 12 Max. (16 planned)

 Antenna Connector Standard-Polarity SMA

 Frequency Range 430MHz -> 440MHz, with a UK (459MHz option)

 Frequency Bands 431-433, 433-435, 435-437, 436-438, 430-430 EH
