or user-modified files to the product can cause operational errors or cause serious problems with
the product. ROSE is not responsible for any problems that arise in this case.
7. If the touch screen is damaged, do not touch it with your hands. Contact the service center
immediately, as it may cause injury.
8. When you‘re not going to use the product for a long time, be sure to unplug the power plug from the
AC outlet. Even after the power has been shut off (manual standby mode), a minimal current remains
in the equipment. Remove the plug to prevent power consumption.
9. To ensure trouble-free use, you must first connect the power then turn on the device by pressing
the power button on either the remote control or the device itself. You can turn the power off by
pressing the same button.
10. After connecting the power plug and turning on the equipment with the power button, it takes about
10 seconds to complete booting, so please wait for a while.

is turned off, press the power button on the main unit or the remote control to turn it back on and
use it again.
12. Do not power on the device within 10 seconds after shutting off the power and entering manual
standby mode. Doing so may cause noise.
13. Install the product close to an outlet so that it is easy to remove the plug from the outlet.
14. Do not use the product near water. Do not expose the product to a dripping or splashing
environment and do not place objects containing liquids, such as vases, on the device.
15. Do not block the ventilation openings. Install this product according to the product installation and
orientation instructions.

• 3-3-3. Reboot after installing USB Audio Device Driver.
• 3-3-4. After driver installation is complete, switch the source to USB IN in the In/Out Setting,
and you can check the RD160-DAC on your PC as shown below.
• 3-3-5. When you set the sound device to RD160-DAC in the system tray area of your PC, you are
ready to use the device connected to the USB IN port.

3-6. EXT. CLOCK Connection
• You can use an external clock by connecting it to the EXT. CLOCK port of this product as shown in the
figure below.
• To use the master clock using an external device, you can select “External 50Ω” or “External 75Ω”.
※ Please make sure that the external device has an output impedance value of 50Ω or 75Ω and connect it to
the appropriate port.

3-7. Circuit Breaker
• This is a circuit breaker terminal to protect the circuit from damage caused by overvoltage or
overcurrent.
• Similar to the power circuit breaker in a home, when overvoltage or overcurrent is applied from the
outside, the switch terminal protrudes outward to block the power supply. When pressed again by
hand, the terminal is inserted inward, connecting the internal circuit to the power supply.
※ If the protruding motion is repeated even after you press the switch, there may be a problem with the internal
circuit. Please remove the power cord and request product repair.

3-8. GND Connection
• You can ground the GND terminal of an external device to the GND terminal of this product as shown
in the figure below.
※ When a lot of noise is generated, you can reduce the noise by connecting this GND terminal to the signal
GND of an external device.
※ Reversing the signal GND connection may increase noise and cause unintended errors. In this case, please
remove the signal GND connection line between the devices.

Things to Check Before Contacting the Service Center
• Please restart the product if the screen freezes. Press the power button to turn the power off, then
turn it back on.
• If the switch does not work while the product is in use, it may be because it was exposed to severe
static electricity. Please disconnect the power cord before starting again.
• When the product is used for a long time in a confined space that does not meet the product
installation conditions (p. 24), it may generate heat and become hot, affecting the life and
performance of the product.
Always keep the ventilation openings on the top of the main body open so that heat dissipation inside
is not disturbed.
• If there is no output sound, check the input source selector of the main unit, and check that the
speaker connection status, and the volume control level are not “0.”
• If the remote control does not work, the battery may be empty. Replace it with a new battery.
