13. LOUD/RMON
When pressed for less than 1.5 seconds:
Pressing this key turns on the LOUD display and sets the LOUD pin to the high level. Pressing the key again turns
off the LOUD display and sets the LOUD pin to the low level. This operation also turns on and off the loudness
function implemented in the LC7538JMD.
This operation is valid when HOLD is high and main power is on.
When pressed and held down for over 1.5 seconds:
1. When the diode matrix RMON FF/REW setting is 0:
This key operation has no effect. When the FF-REW pin goes high, regardless of the state of this key, the
LC7233N-8818 enters radio monitor mode temporarily. The RMON display flashes at a 1 Hz rate and radio
reception becomes possible.
2. When the diode matrix RMON FF/REW setting is 1:
When this key is pressed the RMON display lights. When the FF-REW pin goes high in this state, the
LC7233N-8818 enters radio monitor mode temporarily. The RMON display flashes at a 1 Hz rate and radio
reception becomes possible. Pressing this key again clears radio monitor mode and returns the LC7233N-8818
to the previous mode.
Operations 1 and 2 are both possible in VF mode even in the DK wait (standby) state.
This operation is valid when HOLD is high and main power is on.
14. POWER (when the diode matrix POWER SW setting is 1)
This key is used when the tact key in the key matrix controls the power. When this key is pressed the POWER pin
goes high and furthermore, the LC7233N-8818 switches to tape mode if there is tape input or to CD mode if CD is
on, i.e., if the CDIN pin is low.
15. MO/ST
When the LC7233N-8818 is in an FM radio mode (including VF mode), pressing this key turns on the ST display.
Pressing this key again turns off the ST display.
However, note that this operation is valid for both the FM and MW bands in products for the US and Japanese
markets when the diode matrix AM ST SEL setting is 1. This setting can be specified independently for the FM and
MW bands (but not for each of the FM1, FM2, FM3, MW1 and MW2 bands).
