Troubleshooting
Receiver/Tuner
• When the INPUT MODE key is pressed for 2 seconds or longer, “RF
OFF” will be displayed. In this condition, the main unit can not re-
ceive remote control signals. Press the INPUT MODE key again for at
least 2 seconds to display "RF ON".
The RF remote control function does not work.
• Connect the antenna.
• Make sure that the correct RF band is selected.
• The operation range of the remote control unit will be influenced
according to the material of the obstacles between the remote control
unit and the receiver. Please confirm that there is no such influence.
• Make sure that no interference from electrical appliances occurs.
Receiver/Tuner
My receiver won’t turn on and the STANDBY indicator is flashing
Your receiver is in the “protection” mode.
Check that:
• The speaker system’s impedance is not too low. See Chapter One of
the Connections and Setup Guide.
• The speaker wires are not short-circuited. Test the wires as follows to
find the shorted wire and replace it:
1 Turn off the receiver, disconnect the positive and negative speaker
wires of the RIGHT FRONT speaker from the receiver, and turn
the receiver back on.
2 If the STANDBY indicator stops flashing, replace this wire.
3 If the STANDBY indicator does not stop flashing, turn off the re-
ceiver, reconnect the speaker wires, and repeat the first step for the
next speaker.
4 Continue until you have isolated and replaced the shorted wire.
5 See Chapter One of the Connections and Setup Guide.
If none of the above solutions work, reset the microprocessor:

Troubleshooting
Receiver/Tuner
1. Turn the receiver off.
2. Unplug the receiver.
3. Plug it back in while pressing and holding the Power switch (you may
need someone else to help you do this)
(For KRF-V7773D)
1. Turn the receiver off. (The Power switch is OFF position.)
2. Press ON/STANDBY key while pressing and holding the Power switch.
The following settings are cleared:
• The component set as input (Tuner is selected by default)—see
“How Do I Operate Devices?” on page␣ 28 of this manual.
• The volume setting (-65dB is selected by default)—see “Adjusting
the Volume” on page␣ 10 of this manual
• The tuner’s receiving band (FM is selected by default)— see “Ra-
dio Tuning” on page␣ 35 of this manual
• The tuner’s frequency (87.5MHz is selected by default)— see “Ra-
dio Tuning” on page␣ 35 of this manual
• The tuner’s preset memory—you will need to reset your stored
radio stations (see Chapter Two of the Connections and Setup Guide)
• The surround setting—see “What are Listen Modes?” on page␣ 17
of this manual.
• The speaker settings—you will need to reset your speaker settings
( see Chapter Two of the Connections and Setup Guide)
Reset the cleared settings before operating the receiver again.
The sound is distorted, and the CLIP indicator on the receiver’s
front panel flashes red continually, or stays red for more than 1
second at a time
Lower the analog input level for the source component you’re listening
to. (Setting the proper input level eliminates distortion that occurs if a
source component’s output level is too high. When this happens, the
front panel CLIP indicator will flash red continually or remain red for
periods of 1 second or longer. Occasional brief flashing of the CLIP indi-
cator is okay). Adjust the analog input level for that component: See “Ad-
justing the Input level” on page␣ 15 of this manual.
