Problem
The receiver has no lights on. Inspect the AC power cord. Be sure it is inserted firmly into the power-cord
socket of the receiver.
Check the AC power outlet. Verify that the outlet is providing power (i.e., a
switched AC outlet).
Ensure that the ZR-4630 is always plugged into an unswitched AC outlet. If you've
checked the cord and the outlet, and you still have no lights, call Niles for service.

Problem Troubleshooting
The keypad is connected, but
no lights come on.
Ther
e is no IR contr
ol of the
source components.
Test the keypad cable with an appropriate cable tester.
The Sensor
s may be r
eceiving some interference. Check the status LED.

hen using the Niles IRR-4D+ W
all Mount or the Niles TIR-1+ Tabletop IR
Sensors, the Status LED should be illuminating green when the zone is on.
The Status LED should be off when the zone is off, and it should be red when
it is receiving a command.
When using the Niles MS-1, MS-2 IR Sensors, the Status LED should be off
when the zone is ON. It should only illuminate green when receiving an actual
IR command.
If the LEDs stay constantly red (or green when using MS-1 or MS-2), that is a
sign of interference. Identify the source of interference and remove it, or move
the sensor to a place where it doesn't hav
e int
erf
er
ence. Sources of interference
may include dimmer switches, fan motor switches, televisions (especially
plasma televisions), and sunlight.
Some IR commands work for a
sour
ce and some don't.
You may have captured some IR commands incorrectly. Testing all IR
commands as y
ou captur
e them with the IR test feature will avoid this.
