Use the preceding circuit, but

swap the locations of the

speaker (SP2) and color

LED (D8). Now the color

LED is at full brightness

during playback, and RV

adjusts the sound volume.

Set the 500kW adjustable resistor (RV3) to

mid-range. Turn on both slide switches (S1),

you hear a beep signaling that you may begin

recording. Talk into the microphone until you

hear a beep (signaling that recording time is

over), then turn off the left slide switch to exit

recording mode. Push the press switch (S2)

to play back the recording, and turn the knob

on RV3 to change the playback speed. You

can play your recording faster or slower by

changing the setting on RV3.
Move the lever on the adjustable resistor

(RV) to change the brightness of the color

LED (LED) during playback. Most of RV’s

range will give little or no LED brightness.
Recording time is 6 seconds at normal speed,

but this can be changed depending on the

setting of RV3 when you are making the

recording.

Use the preceding circuit, but replace the

1mF capacitor (C7) with the 0.1mF capacitor

(C2). The sound is a little different now, and

the green keys can change it.

Turn on the slide switch (S1).

Move the lever on the

adjustable resistor (RV) around

near the left (not the middle or

right). Press any of the blue

keys for more effects. Pressing

the green keys may not do

anything.
