Notes:* Before measuring the items under Playback Mode, input a 0 to 5.0 V trigger pulse to T5 (H-SYNC), the pin from which the LA70011 takes its T3

(HA) control switch timing.

* The resistance between pins 13 and 14 must be accurate to within 1.0%.

*1. These are voltage application points.

*2. Apply a DC voltage of approximately 1.8 V to the AGC wave detector filter pin (pin 15) to fix the AGC amplifier gain.

*3. Apply a DC voltage to the REC-CUR-Adj pin (pin 12) and adjust the output level.
