DESCRIPTION

TYPE

Local output

Radio mode LOCAL signal output pin.

This pin is valid when the initialize diode AUTOLOC

switch is 0.

Each time the

LOC

key is pressed, the LOCAL

state is inverted. In the LOCAL state, the LCD panel

“LOC” display lights.

When autotuning (seek up/down, scan up/down, auto

memory) is performed when the “LOC” display is ON,

High level is output from this pin. The LOCAL state is

common to the FM, VF, MW, and LW bands.

When the power is turned on, this pin goes low.

from this pin. Therefore, use it to turn the tuner power on

and off, etc.
