Indicator
Description
SRS
This indicator indicates the SRS status.
It lights when SRS is on in the power-on status.
At all other times, it remains dark.
I
II
These indicators indicate the reception band of the radio, with digits <1> and <2>.
They light when the corresponding band is being received in the radio mode.
At all other times, they remain dark.
For display of a reception band, refer to the description of digits <1> and <2>.
:
This is the colon for clock display.
It blinks at a frequency of 1 Hz and with a duty factor of 50% when digits <4> through <7> display
the time.
At all other times, it remains dark.
For the clock display, refer to the description of digits <4> through <7>.
.
This is a decimal point for frequency display of the radio.
It lights when digits <3> through <7> indicate a frequency of the FM band in the radio mode.
At all other times, it remains dark.
For the frequency display, refer to the description of digits <4> through <7>.
TRACK
This indicates that digits <8> and <9> indicate a track number of the CD player.
It lights when digits <8> and <9> indicate a track number in the CD mode.
At all other times, it remains dark.
For the track number display, refer to the description of digits <8> and <9>.
CH
This indicates that digit <9> indicates a preset memory number of the radio.
It lights when digit <9> indicates a preset memory number in the radio mode.
At all other times, it remains dark.
For the preset memory number display, refer to the description of digits <8> and <9>.
Digits <1> and <2>
These digits indicate the following:
(1) Reception band of radio
(2) a.m./p.m. of the clock
At all other times, they remain dark.
(1) Reception band of radio
Digits <1> and <2> indicate the reception band of the radio in the radio mode, in accordance with the
“I” and “II” indicators, as follows:
“ F MI ”: FM1 band is received.
“ F MII ”: FM2 band is received.
“ F MIII ”: FM3 band is received.
“MW”: MW band is received.
“ L W”: LW band is received.
“ A MI ”: If the intended region is USA 1 or USA 2 and AM1 band is received
“ A MII ”: If the intended region is USA 1 or USA 2 and AM2 band is received
For the assignment of the MW and LW bands to the AM1 and AM2 bands, refer to “3.1 Receivable
Bands”.
(2) a.m./p.m. of clock
In the 12-hour mode of the clock, a.m. and p.m. are indicated as follows:
“ A M”: a.m.
“ P M”: p.m.
For the clock display, refer to the description of digits <3> through <7>.
