Yamaha K-540 Owner's Manual page 9

_ After turning on the power to each component, select
the station on your tuner which you want to record and
turn down the volume on your amplifier. This will have
no effect on the recording signal level. Remember to
set the proper recording level.
Set the timer to the desired times. It is advisable to set
the timer to begin recording slightly before the actual
recording time, and end slightly after the actual
recording time, so that you leave some room for later
editing. |
_ Set the AUTO MODE selector to the TIMER REC
position.
The timer will send power to the amplifier, tuner and
deck at the preset time, turning all the components on
and initiating the recording mode.
CAUTION:
If the tape cannot be ejected after timer recording, turn
the AUTO MODE selector OFF and the K-540's POWER
switch ON; the tape can then be ejected.

After using your K-540 for a certain length of time, it is
possible that the sound of your tapes may deteriorate with
` - fading, vibration, or noise as a noticeable result. This is
caused by an accumulation of dirt or dust on the heads,
capstans, or pinch rollers, and magnetization of the heads.
It is advisable to clean the capstan and pinch roller. Use a
commonly available cotton swab and head cleaning
solution to do this, or use a special head cleaning tape.
Head demagnetizers are also commonly available.
e When cleaning the heads, be careful not to apply
unnecessary pressure.
ə When demagnetizing the heads, be sure to follow the
instructions of the head demagnetizer carefully.
ə For better access to the head assembly, the cassette
compartment cover is detachable by pulling upward.
To reattach it, reverse the same procedure.
