Key Description

• CH1 to CH8
Key for writing/calling preset channels 1 to 16 (FM), 1 to 8 (AM). CH1 key, CH2 key correspond to channel 1/9, 2/
10, respectively. For example, when you push CH1 key and release it within 0.5 second, CH1 is called ; and when
released in 0.5 second or more, CH9 is called.
When you push ME key, is displayed on the frequency display area and CH1 to 8 may be written for 5 seconds.
If you push ME key once again within 5 seconds, is displayed and CH9 to 16 may be written. When you push an y
one key of CH1 to CH8 , your desired channel is written in a specified memory.

•ME
¡ Used to write a new channel in the preset memory. When you push this key once, (mode 1) is specified. When

you push twice, (mode 2) is specified. When you push once again, returns.
The write enable mode is released automatically 5 seconds after this key pushed.

™ When you push this key together with TIMER key, the timer setting mode (time setting mode) is entered.

• A/M (AMAN DIMRX=1)
Key for selecting the auto/manual tuning mode. Each time you push this ke y, the mode is switched as auto → manual →

auto ..... AUTO display flashes at the auto mode.

• TUP TDN
¡ Manual mode

Each time you push these keys, the channel No. goes up/down by one. When you hold these keys pushed for 500ms
or more, the channel No. goes up/down at a 60ms/step rate.

™ Auto mode (AMAN DIMRX=1)

A broadcasting station is searched automatically in an up/down direction and a receiving frequency is held. If you
hold this key pushed when the receiving frequency is reached, no auto stop occurs but a temporary stop (500ms)
occues. The searching rate is 60ms/step.

• FM MW LW SW
Key for band selection.

• BAND
Key for band selection. Each time you push this key, band switching occurs.

Continued from preceding page.

•PS
Key for preset scanning. When you push this key, the channel No. is changed in the order of increasing channel No.
beginning with a channel No. currently displayed. If no channel No. is displayed, the channel No. is changed from
CH1. If there is a channel that can be received during preset scanning (SD=“L”), a sound is generated for 5 seconds and
if there is no channel that can be received, the channal No. is displayed for 1 second with no sound generated and the
channel No. is changed to the next one. The channel No. flashes at a 1Hz rate during preset scanning.

The preset scanning mode is released by pushing this key twice.

•POWER
Switch for turning ON/OFF the power supply of LC7230-8272-applied equipment. Each time you push this key, the

level at output pin PWR OUT is switched as H → L → H ...... The volume level at the power-ON mode is the same as

for the previous power-OFF mode.

• TIMER (Causes turn-ON mode only. Not cause turn-OFF mode “ONCE” timer only.)
Key for providing time display at the timer setting mode, time setting mode or frequenc y display mode . When you push
this key together with ME key, the timer setting mode is entered ; and when you release the two keys once and push
them again simultaneously, the time setting mode is entered.
When you push ME key in the timer setting mode, the timer time setting is enabled with the timer time flashing and the
standby mode is entered. TDN key and TUP key are used for hours setting and minutes setting, respectively. These
settings are made in an up direction only. Each time you push TDN key or TUP key, the display contents increment
by one. When you hold TDN key or TUP key pushed for 500ms or more, the display contents advance at a 4 hours/
second rate or 8 minutes/second rate, respectively.
When you push ME key after completion of setting, a volume lev el at the timer tur ned-ON mode can be set. A digitally
displayed volume level at this moment is the same as for the previously set value. The setting range is from –16dB to
–80dB. The volume level at the initial mode is –50dB.
When you push ME key after completion of setting, the time display mode returns. When you wish to check the set
time only at the timer setting mode, push ME key twice to return the mode to the timer display mode.
Next, in the time setting mode the time setting is enabled with the time display flashing. The setting method is the same
as for the timer setting mode. When you push ME key after completion of setting, the second display is cleared to zero
and the time display mode returns.
When power is turned ON at the initial mode, the time setting mode is entered.
When you push a function key during timer setting or time setting, such mode is released.

• SLEEP
Key for sleep time setting. When you push this k e y in the SLEEP display OFF state, the SLEEP display is turned ON
and (minutes) is displayed. Each time you push this key , decrements in units of 10 minutes. When is reached,
SLEEP display is turned OFF and the sleep time setting mode is released. The previous mode returns 5 seconds after
a sleep time is set to a specified value ( SLEEP key is released).

When you push the SLEEP key while in clock display or frequency display, the remaining sleep time is displayed.
5 seconds after releasing the key the previous status will return.

• TIMER ON

•CD
When you push this key in the state where the PHONO, TAPE, AUX, TUNER functions are provided, data is trans­ferred to the LC7821 (N), the function is switched to CD and CD display is provided. You can also use this key for the
CD power supply control signal and LED function display.

• PHONO
When you push this key in the state where the TAPE, AUX, TUNER, CD functions are provided, data is transferred to
the LC7821 (N), MLC74HC375, the function is switched to PHONO display is provided.

• TAPE
When you push this key in the state where the AUX, TUNER, CD PHONO functions are provided, data is transferred
to the LC7821 (N), MLC74HC375, the function is switched to TAPE , and TAPE display is provided.

•AUX
When you push this key in the state where the TUNER, CD PHONO functions provided, data is transferred to the
LC7821 (N), MLC74HC375, the function is switched to AUX and AUX display is provided.

• VUP VDN
Keys for increasing/decreasing the electronic volume control level. Each time you push these keys, the level goes up/
down by 1dB. When you hold theses keys pushed for 500ms or more, the level goes up/down at a 150ms/dB rate.

Custom Code of the LC7461M-8103

The LC7461M-8103 is a remote control signal transmission IC to be used in conjunction with the LC7230-8272.
The custom code of the LC7461M is such that the 7 bits are fixed by the internal metal mask and the remaining 6 bits are
set using the IC pins.
Custom code 0100H is available for e valuation. When performing evaluation, the code of the LC7461M-8103, LC7230­8272 must be set to this code value.
When evaluation is acceptable, a custom code to be used must be assigned before mass production of equipment and your
draft on remote control IC should be submitted.
How to set code 0100H for evaluation.

When a custom code for mass production is assigned, C0 to C4 are set to 1 (connected to VDD) or 0 (connected to VSS)
according to the specified code.
Note) A code of the LC7230-8272 is set according to 1 (with diode) and 0 (without diode).
