Setting the Pushbuttons
Make a list of your 6 favorite stations. Push out the call letters of these stations from the call letter sheets supplied. Insert a call letter in the front of each pushbutton.
Next push one of the pushbuttons all the way in as far as it will go and hold it there. Now tune in the station you want with the tuning knob Tune back and forth until the station is clear and distinct, then release the button. Continue setting each push button in the same way. Now rotate the tuning knob to the right (clockwise) as far as it will turn.
Looking at the back of the cabinet note the reset lock screw on the left hand side of the chassis, (see chassis view),
Rotate the reset lock screw to the right (clockwise) by means of the pin thru the shaft.

It is very important that this locking screw is turned until it is absolutely tight.
This screw will lock in place all the stations you have selected on the automatic tuner pushbuttons. Pressing the proper button will now tune the station you want. (NOTE: Locking screw is loose when radio is shipped from factory).
To change stations simply loosen the reset lock screw and repeat the procedure above.
