SPLICING TAPE
1. Use splicing tape and a pair of scissors. Do not use
ordinary cellophane tape as it tends to deteriorate.
2. Overlap the tapes to be spliced and make a diagonal cut
across the overlapped position.
3. Place a piece of splicing tape on a flat surface, pasty side up.
On the splicing tape, put and press the two diagonal-
tape-ends, shiny side down.
¢y Be careful to make ends meet, but not overlap.
x The two tapes spliced must make a straight line.
4. Trim off the excess splicing tape.
MAINTENANCE
Cleaning heads
Optimum performance will be assured by clean heads. Remove
the head cover by loosening the screws at the rear of the cover.
Take the supplied head cleaning tip or a soft cloth and wipe
the heads and the tape guide over which the tape travels. When
the deposits cannot be removed, moisten the tip or the cloth
with denatured alcohol and repeat cleaning.
Demagnetizing heads
Although the TC-252D incorporates a circuit to demagnetize the
record head, under certain conditions such as prolonged playback,
residual magnetism would gradually build up on the heads,
causing degradation of tapes. Periodic use of the SONY HE-2
head demagnetizer is recommended to maintain optimum
performance,
Lubrication
Use light machine oil and lubricate capstan, pinch roller shaft
and idler shafts every 6 months. Avoid excessive lubrication.
It will cause slippage of the mechanism and contamination of
your tape. Remove the Function Selector by loosening the screw
located beneath the lever. Remove the head cover, Tape Speed
Selector and four screws from the top panel of the recorder
and lift up the panel. Take out the caps of the pinch roller and
the three idler shafts. Lubricate the capstan, the idler shafts
and the pinch roller shaft with 1 drop each of light machine oil.
