GUIDE

AAA

Antenna

The MRX-16 receiver is supplied with an attached

Antenna (5). It should be extended fully to

obtain maximum range. For maximum range,

it is always best to maintain a line-of-sight (no

obstructions) between the receiver antennas and

the transmitter whenever possible.

Powering the Receiver

The MRX-16 receiver can operate with either

two AA size batteries (DC operation) or with the

supplied AC adaptor (AC operation).

For DC operation, open the receiver’s

Battery Compartment Door (1) and

place a fresh AA Battery (2) in the Battery

Compartment (3), observing the correct polarity.

A fresh alkaline or NiMH AA battery will generally

provide 6-8 hours performance, but in order to

ensure optimal performance it is recommended

that the batteries be replaced after six hours of

use, or as indicated by the Low Battery Indicator

(7). As the battery begins to weaken below

usable voltage, the low battery indicator will ash

continuously, warning that the battery is now too

low and should be replaced as soon as possible. To

preserve battery life, keep the receiver Off when it

is not in use.

Turn on the MRX-16 receiver by sliding

the Power Switch (11) to the second

position (receiver On but audio output muted/

attenuated), or to the third position for normal

operation (receiver On and audio un-muted).

The Power & Low Battery LED (7) will ash

once indicating receiver is operational.

SYSTEM OPERATION

MRX-16 Receiver

Selecting the MRX-16 Receiver

Channel and IR Sync

The Frequency Select DIP Switches

(9) are used for selecting one of 16

preset frequencies. Simply position the

DIP switches to a desired open channel

on the receiver. There should be no

ickering of the RF Signal LED (6) with

the transmitter off. See the MRX-16 DIP-

Switch Frequency Selection Chart on

page 16 for the correct switch position for

each of the 16 available channels. Once

you have selected the receiver frequency

it can easily be downloaded to the

transmitter to establish the necessary RF

connection. For further info on selecting

open channels, see RF Interference and

Finding Open Channels on page 15.

The IR Sync Button (8) on the MRX-16

receiver

is used to transfer the selected

frequency info from the receiver to the

transmitter for quick synchronization prior

to use. Begin programming by holding

the wireless transmitter’s IR Receptor/

Sensor Window (21, 31, 46, 56) about

6-12” from the receiver’s IR Synch

Infrared LED Window (12). Press the

IR Sync Button once to begin the IR sync

download of the selected frequency to the

transmitter.

Note: To insure proper synchronization, the

transmitter must always be just turned on, or

else turned off then on again, before syncing
