Description
This switch is used to select 12-hour or 24-hour clock display.
Set this switch as indicated in the following table.
CTADJ
CLK24
Hour display
0
12-hour clock display (with “AM” or “PM” displayed)
1
24-hour clock display
(0: Open, 1: Jumpered)
This switch is used to select whether the clock is adjusted according to RDS data.
The clock is not adjusted during power off.
When no-clock mode is selected (initial setting diode NOCLK = 1), this setting is invalid.
Set this switch as indicated in the following table.
CTOFF
CTADJ
Adjusting clock with RDS data
0
Does not adjust the clock with RDS data.
The clock must be adjusted by the user.
1
Adjusts the clock according to the RDS data.
The clock cannot be adjusted by the user.
The clock does not operate until the RDS data is input.
(0: Open, 1: Jumpered)
This switch is used to select how the clock operates in power-off mode.
When no-clock mode is selected (initial setting diode NOCLK = 1), this setting is invalid.
Set this switch as indicated in the following table.
DEV_SEL
CTOFF
Clock operation
0
Operates normally.
1
Stops operation.
Initializes the clock.
The clock can be backed (with low current consumption) when a low level signal is
input to the ACC or BATT pin.
(0: Open, 1: Jumpered)
This switch is used to select whether the DEV_LEVEL pin (pin 66) is referenced during AF operation.
Set this switch as indicated in the following table.
DEV_SEL
0
Not referenced.
1
Referenced.
(0: Open, 1: Jumpered)
