NOTE
REMOVAL AND INSTALLATION OFFLAT PACKAGE IC
Some ICs on the PCB are affixed with glue, so becareful not to break or damage the foil of each ICleads or solder lands under the IC when removing it.
NOTE
Masking is carried out on all the parts located within10 mm distance from IC leads.

IC
Heat the IC leads using a blower type IC desolderingmachine. (Refer to Fig. 3-2.)

NOTE
Do not add the rotating and the back and forthdirections force on the IC, until IC can move back andforth easily after desoldering the IC leads completely.
When IC starts moving back and forth easily afterdesoldering completely, pickup the corner of the IC usinga tweezers and remove the IC by moving with the ICdesoldering machine. (Refer to Fig. 3-3.)

NOTE
When the IC leads are bent during soldering and/orrepairing, do not repair the bending of leads. If thebending of leads are repaired, the pattern may bedamaged. So, always be sure to replace the IC in thiscase.
Finally, confirm the soldering status on four sides of theIC using a magnifying glass.Confirm that no abnormality is found on the solderingposition and installation position of the parts around theIC. If some abnormality is found, correct by resoldering.

Turn the screw 2 to set the audio level to maximum.Confirm that the bottom of the Audio/ Control Head andthe bottom of the tape is shown in Fig. 2-2-C.c)
When the reflected picture is distorted, turn the screw1 clockwise until the distortion is disappeared.When the reflected picture is not distorted, turn thescrew 1 counterclockwise until little distortion isappeared, then adjust the a).
When the height is not correct, turn the screw 3 toadjust the height. Then, adjust the 1~3 again.
