2. UP/T-UP, DOWN/T-DOWN
When the diode matrix AUTO500 setting is 0.
Each time one of these tuning keys is pressed the frequency is increased or decreased by one step. If a tuning key is
held down for over 500 ms, the frequency is advanced rapidly at about 70 ms per step. When the frequency
changes from band edge to band edge, the LC7233N-8818 pauses for about 500 ms.
When the diode matrix AUTO500 setting is 1.
When these keys are held down for less than 500 ms they function as manual tuning keys, and when held down for
over 500 ms, the LC7233N-8818 enters seek mode.
Both of these functions are valid when HOLD is high, PANEL IN is low and main power is on.
In VF mode, these keys function as seek up and seek down keys.
3. DISPLAY + UP/T-UP
When the time is displayed, pressing these keys at the same time adjusts the minutes setting. Each time these keys
are pressed and held down for less than 500 ms the time setting is advanced by one minute, and if they are held down
for over 500 ms, the time setting is advanced at eight minutes per second. These operations reset the seconds setting
to zero.
4. DISPLAY + DOWN/T-DOWN
When the time is displayed, pressing these keys at the same time adjust the hour setting. Each time these keys are
pressed the time setting is advanced by one hour, and if they are held down for over 500 ms, the time setting is
advanced at four hours per second. The minute and second settings do not change due to this operation.
5. SEEK UP, SEEK DOWN
These keys automatically search for a station broadcast and lock onto the received station. If the SCAN key is
pressed during a seek, the LC7233N-8818 switches to scan mode. Therefore, if the SCAN UP key is pressed during a
downward seek, an upwards scan is started. Also, during a seek up (down), if seek down (up) is pressed, a seek down
(up) operation is started. The search mode is cleared by pressing the same key a second time. When the frequency
changes from one band edge to another, the LC7233N-8818 pauses for 500 ms. The search speed is 50 ms/step for
FM and 70 ms/step for AM.
These functions are valid when HOLD is high, PANEL IN is low and main power is on.
6. SCAN UP
The scan function automatically searches for the next station, and when a station is found holds that station for 5
seconds (with AMUTE at the high level) and flashes the channel display. Pressing this key once more during that
interval causes the LC7233N-8818 to hold at that station. If no user action occurs during that 5 second interval, the
search resumes.
Pressing the SEEK DOWN key during a scan starts a downward seek operation. Scan mode is cleared by pressing
the SCAN UP key a second time. When the frequency changes from one band edge to another, the LC7233N-8818
pauses for 500 ms.
The search speed is 50 ms/step for FM and 70 ms/step for AM.
This function is valid when HOLD is high, PANEL IN is low and main power is on.
