System Setup
System Setup
ECMR Receiver Setup:
Channel Selection
Press channel Selector button to select desired Channel. When
switching Channels, wait for the Channel number display to stop
blinking before using the ASC function. For best results when
operating multiple systems, set every channel to achieve the
maximum distance between channels.
Receiver Volume Control:
Turn Left for Output Level decrease, turn Right for Output Level
increase.
Mute Level Threshold Adjustment:
The Mute Level is factory set and normally needs no adjustment.
However, you may turn clockwise if interference is present.
Automatic Transmitter Setup (ASC):
Remove the access cover on the Handheld Transmitter. Point the
IR Window of the Handheld towards the IR Window on the
Receiver and press the ASC button.
Start by pressing the ASC button on the MBP52 transmitter belt
pack. The LED on top will flash green for 15 seconds.
While it’s flashing, point the IR window of the MBP52 belt pack
towards the IR window on the Receiver, and press the ASC
button on the ECMR receiver. If you have successfully synced
them, the orange RF LED on the ECMR receiver will turn on
indicating a signal from the transmitter.
Note: when establishing infrared connection between the receiver and
the transmitter, the distance between them should not exceed 1.64ft
(0.5m). When more than one system are used, only IR window of one
transmitter should be pointed to the receiver for each infrared
connection.
“Only one IR Window from each transmitter should be pointed to the
receiver for each infrared connection.”
