Notes

The LA1061M counts antenna

switches for the time interval

generated by multi-vibrator 2.

The internal D/A converter

outputs a current on pin 11,

which is converted to a voltage

by the resistor connected to

this pin. If this voltage exceeds

a certain value, that is, the

switching frequency is too

high , multi-vibrator 3 operates

to hold the antenna switching

outputs at Main for the time set

by multi-vibrator 3.

The threshold level is set at

approximately 2V.

The threshold level is set at

approximately 1V.
