HEAD CLEANING
Accumulation of dust and magnetic particles on the heads
results in poor head-to-tape contact and deteriorates sound
quality and sensitivity. It is. therefore, recommended that
the heads he cleaned every time you use your recorder.
Remove the Head Cover and with a stiff cotton swab
dipped in cleaning fluid ( Akai Head C leaning Kit HC-500 is
highly recommended) rub the entire head surface (do not
scratch) until all tape oxide and dust are removed. The
capstan shaft, tape lifter and other parts over which the tape
travels should also he cleaned.
• Do not use chlorolhanc as it will damage the rubber wheel.
HEAD DEMAGNETIZING
Normally, the steel pole pieces which form part of the
recording and playback head become slightly magneti/.ed.
The effect of magnetization will cause considerable drop
out or introduce noise into your recordings. It is recom
mended that head demagnetization be performed periodi
cally. This can be accomplished with a bulk demagnetizer
by bringing it close to the heads and making several small
circular motions over all head surface areas as well as the
head housing.
* Be sure tu cut off the power of the unit, prior to demagnetizing
the heads.
* Both prongs of the demagnetizer should he covered with masking
tape to prevent the heads from being scratched.
* Do not use magnetized tools in the vicinity of the heads.
* Read the demagnetized instructions carefully before operation.
