/IR Sync Manual Programming
To manually program the pre-selected Group/Channel (frequency) from the receiver to the
transmitter, place the transmitter’s IR RECEPTOR SENSOR WINDOW (37) 6-12” away from the
receiver’s IR WINDOW (12). Press the MENU BUTTON (14) four times to the IR Screen Display
and then press the UP BUTTON (13) to start IR programming. The flashing IR INDICATOR (22)
icon indicates IR transmission is in progress. When the synchronization is completed success-
fully (usually in less than 2 seconds), the RF INDICATOR (19) and the diversity A or B INDICA-
TOR (20) on the receiver will display, indicating that the IR linking is completed. The LCD
DISPLAY SCREEN (16) will show the selected channel. If the UP Button is not pressed during the
two seconds of active data transfer, the IR INDICATOR (22) will not flash, the LCD Display will
revert to the main menu, the receiver will not link to the transmitter, and the transmitter’s
previously programmed channel remains unchanged.
Instructions for the Setup of Simultaneous Multichannel Operation
This UDR800 receiver is capable of finding an open channel with its autoscan capability.
This built-in feature is a quick, convenient way to set up many wireless systems at the same
location for simultaneous multichannel operation.
If you are using multiple transmitters at the same location, set up the first transmitter and leave
it ON and keep it 10 feet away from the receivers and 1 foot or more between transmitters.
This avoids possible duplicate selection of the same channel as already selected for the first
receiver. Then start the autoscan function on the second receiver. Repeat this procedure for all
receiver/transmitters to be used in your system. Finally with all the transmitters ON, perform
a range walk test in the location these systems will be used in to check for potential crosstalk
interference in this application.
If you are not satisfied with any of the channels scanned, repeat the autoscan procedure for
that receiver again anytime for finding another free channel. This process can be simplified
if you select channels within Factory SELECTED Groups 11 to1A, as the channels within those
groups are mutually compatible (unless there is outside interference on any of the selected fre-
