Troubleshooting - Esoteric RZ-1 Mode D'emploi

If you experience any problems with the unit, please take a moment
to look through this chart and see if you can solve the problem
yourself before you call your dealer or ESOTERIC customer service/
technical support.
Moreover, the problem might be caused by something other than this
unit. Confirm that connected devices are also being used properly.
General
No power.
e Check the connection to the AC power source. Check and
make sure the AC source is not a switched outlet and if it is, the
switch is turned on. Make sure there is power to the AC outlet by
plugging another item such as a lamp or a fan.
Remote control does not work.
e If the batteries are exhausted, change the batteries.
e Use the remote control unit within the effective range
(7 m/23 feet) and point it toward the remote sensor on the front
panel.
e Make sure that there are no obstacles between the remote
control unit and the main unit.
e If a fluorescent light is near the unit, turn it off.
Buttons do not work properly.
e If another operation is still in process, wait a moment and try
again.
Other units with remote controls operate incorrectly.
e Note that other units with remote controls may operate
incorrectly because of infrared light "overspill" when you operate
the remote control of this unit.
Severe hum or noise is heard.
e Place the unit as far away from a TV as possible.
There is no sound or only a very low-level sound is heard.
e Adjust the volume by pressing the VOL (+/−) buttons.
e Check that the speakers and components are connected
securely.
e Check the operation of the connected component.
e There might be a +/_ short in a speaker cable. Check the
speaker cables.
e Select the proper input source using the SOURCE button.
There is no sound from a connected digital device.
e When connecting the digital output terminal of a DVD player or
other digital device, set the digital audio output of the connected
device to PCM. You can also connect the analog outputs of a
digital device to this unit's analog inputs (LINE IN).
The display shows "AMP ERROR!".
e See "Protection Circuit" on previous page.

Troubleshooting

CD/Super Audio CD Player
Will not play.
e Press the SOURCE button repeatedly to select "CD/SACD".
e Reload the disc with the label side up. If not, insert the disc
correctly.
e If the disc is dirty, clean the surface of the disc. If the disc is
scratched or has any sticky substance on it's surface, do not play
the disc until you have corrected the condition of the disc. Under
all circumstances, do not use after market stick on labels or "disc
enhancement" devices that sit on top of a disc or wrap around a
disc.
e If the unit has become condensed with moisture, leave the unit
for one or two hours with the power turned on.
e The multi-channel area of a Super Audio CD cannot be played
with this unit. This unit is a 2 channel player only.
Noticeable difference in CD and Super Audio CD's volume.
e That is because CDs and Super Audio CDs use different recording
methods. This is normal.
USB connections with personal computers
This unit is not recognized by personal computers.
e USB connections are possible with personal computers running
with Microsoft Windows XP or Windows Vista. Other operating
systems are not guaranteed but may operate. This unit might
not function properly when used with a computer running a
different OS. In addition, the connected computer should be
compatible with USB 1.1 or higher.
Noise occurs.
e Starting other applications during playback of a music file may
interrupt playback or cause noise. Do not start other applications
during playback.
Music files cannot be played.
e Connect this unit to the personal computer before launching
music playback software and starting playback. If the music
playback software is launched or the input of this unit is switched
to "USB" before this unit is connected to the personal computer,
music data may not be played back correctly.
e Check the points on page 20 - 21.
Sound is too low.
e Confirm that the volume settings of the music playback software
and the operating system are not low. Turn up the output volume
on the PC as needed.
Since this device uses a microcontroller, external noise and
other interference can cause the unit to malfunction. If this
occurs, turn the power off and restart operations after waiting
for about one minute.
