Use shielded audio cable for the connection between this unit and the mixer/amp or audio
source. If the mixer/amp has a 1/4"(6.3mm) phone jack, connect a cable from the 1/4"(6.3mm)
unbalanced audio output from the receiver to the mixer/amp. If the mixer has an XLR input,
connect a cable from the balanced XLR audio output from the receiver to the mixer input.

Installation
For best operation, this unit should be at least 1m above the
ground and at least 1m away from a wall or metal surface to
minimize reflection. The transmitter should also be at least 1m
away from a wall or metal surface to minimize reflection. The
transmitter should also be at least 1m away from the receiver.
Rack mounting
QR-4000N has a 19"-casing design. It can be cabinet-mounted with provided kits. Please refer
to the following assembly illustration.
SDR-5200M IrDA｜SDR-5100M receiver modules
1.Channel indicator
2.Diversity A/B indicator
3.Audio signal indicator
4.IR sensor area
5.Channel Selector
6.IRDA synchronizing button
7.Squelch control
8.Power switch/volume
control
First turn on the Power of the main unit. Then turn on the individual power of the receiver
module. Select a channel that corresponds to the transmitter. When transmitter is turned on,
either A or B diversity indicator will flash to indicate that signal has been received.
SQUELCH (SQ) setting
When a channel is in use and undesired interference signal is received, turn the SQ in
clockwise direction to make the receiver less sensitive and thus less susceptible to interference.
If this still does not solve the problem, it means this frequency is not applicable at current
position. Please switch over to the next channel.
Channel synchronizing of the receiver and transmitter
1.To achieve a trouble-free synchronization, please limit the distance between the receiver and
transmitter to within 30cm.
2.Align both sensor areas
3.To change the receiver’s channel, please press the synchronizing button of the transmitter.
The transmitter will transmit synchronizing signal to the receiver and change its channel.
4.To change the transmitter’s channel, please press the synchronizing button of the receiver.
The receiver will transmit synchronizing signal to the transmitter and change its channel.

Battery installation & indicator
This transmitter requires 2 x AA batteries to operate.
To install, remove the battery cover and slide the batteries into the battery compartment &
replace the battery cover.
Note: Batteries contain a corrosive acid that may leak and damage the transmitter when stored
for a long period. Batteries should be removed from the transmitter before storing without use
for more than 4 weeks.
When the transmitter is switched ON, a red LED will blink once to indicate the batteries
installed are in good condition. If the LED remains illuminated, it means the batteries are
weak and require replacement.

Other settings（SQ-6100 IrDA(R)｜SQ-6100 IrDA）
1. Channel setting
Use MENU button to go to the CHANNEL｜FREQUENCY page.︰
After pressing the SET button for 3 seconds, the cursor will flash to allow changes to be made.
Pressing SET / MENU buttons will increase / decrease the channel number. The corresponding
frequency will change accordingly. 3 seconds after selecting a channel, it will be automatically
saved.
2. Battery type setting
Use MENU button to go to the BATTERY TYPE page.︰
After pressing the SET button for 3 seconds, the cursor will flash to allow changes to be made.
Press SET button to select either NiMH (rechargeable battery) or AKLN (alkaline battery). 3
seconds after selecting a battery type, it will be automatically saved.
Remark: NiMH battery must be selected when rechargeable battery is being used. Never
select AKLN (alkaline) when transmitter is intended for charging as alkaline battery isn’t
rechargeable. Wrong battery selection will result in battery sensing electronics to display wrong
and misleading status information.
