Indicator
Description
Digits <3> through <7>
(6) Indication of loading disc
While a disc is being loaded, digits <4> through <7> display the following message, which blinks at a
frequency of 1 Hz and with a duty factor of 50%.
“
L O A D ”: Disc is being loaded. (Blinks at a frequency of 1 Hz and with a duty factor of
50%.)
At this time, digit <3> remains dark.
(7) Indication of ejecting disc
While the disc is being ejected, digits <4> through <7> display the following message, which blinks
at a frequency of 1 Hz and with a duty factor of 50%.
“
E J C T ”: Disc is being ejected. (Blinks at a frequency of 1 Hz and with a duty factor of
50%.)
At this time, digit <3> remains dark.
(8) Indication of no disc
If the CD mode is selected while no disc is inserted, digits <4> through <7> show the following
message for three seconds, which blinks at a frequency of 1 Hz and with a duty factor of 50%.
“
n o C D ”: No disc is inserted. (Blinks at a frequency of 1 Hz and with a duty factor of
50%.)
At this time digit <3> remains dark.
(9) Telephone mute display
If telephone mute by the PMUTE pin (pin 47) is turned on in the power-on status, digits <4> through
<6> display the following message, which blinks at a frequency of 1 Hz and with a duty factor of
50%.
“
T E L
”: Telephone mute display. (Blinks at a frequency of 1 Hz and with a duty factor of
50%.)
At this time, digits <3> and <7> remain dark.
(10) Forced mute display
If forced mute is turned on by the MUTE key in the power-on status, digits <4> through <7> display
the following message, which blinks at a frequency of 1 Hz and with a duty factor of 50%.
“
M U T E ”: Forced mute display. (Blinks at a frequency of 1 Hz and with a duty factor of
50%.)
At this time, digit <3> remains dark.
If both forced mute and telephone mute are turned on at the same time, the telephone mute display
takes precedence.
