• The FUNCTION name of external input terminal can be changed over to VIDEO 1 or MD. With the FUNCTION selected to “MD”, about
5dB mute is applied to the input gain.
Procedure:
1. Press 1/u button to turn the set OFF.
2. Press 1/u button together with FUNCTION button, and the power is turned on, the display of fluorescent indicator tube changes to
“MD” or “VIDEO 1” instantaneously, and thus the FUNCTION is changed over.
Change-over of AM Tuner Step between 9kHz and 10kHz
• A step of AM channels can be changed over between 9kHz and 10kHz.
Procedure:
1. Press 1/u button to turn the set ON.
2. Select the function “TUNER”, and press TUNER/BAND button to select the BAND “MW”.
3. Press 1/u button to turn the set OFF.
