MERRICK Genetix Safety, Installation, Operation And Maintenance Instructions

Page 4 of 15
INTRODUCTION
The Genetix Remote Handheld User Interface is a device that allows you to completely
interact with your Genetix controlled Feeder or Scale in a wireless manner. It is intended
to provide you a means to temporarily control your feeder for calibration, maintenance,
or diagnostic purposes in the absence of a locally mounted, wired User Interface.
The Remote User Interface is battery powered for maximum portability. It operates
wirelessly using the Bluetooth protocol and can connect to any Merrick feeder within
range, so only one Remote User Interface is needed for any number of Merrick feeders.
Note: Each Merrick feeder to which you wish to connect must be equipped with its own
optional Bluetooth interface.
The Remote User Interface utilizes the exact same menu system as the Genetix LCD
Interface, and detailed instructions for this can be found in the appropriate Merrick
Operating Manual. The following sections in this Manual will instruct you in the proper
use of the Remote User Interface, including connection to Merrick feeders.
