. The memory write key indicator changes from a
winking mode to a continuous lighting mode
for about 5 seconds automatically, and the
memory write mode is established.
. If the desired preset key is depressed while the
memory write_key indicator is continuously
lighted, the [recs] data and FM station in-
dicated on the frequency. display are
memorized and the memory write key indicator
goes off.
CAUTION: The field condition computer systems
[Fecs| works only for FM reception.
The memory write mode is held while the
memory write key indicator is lighted. Once this
indicator goes off, the memory write mode is
cleared and it no longer becomes possible to
memorize the stations. The memorizing mode
can be re-established by depressing the
memory write key again since this operation
restores the memory write mode.
CAUTION: This unit incorporates a random ac-
cess presetting system which means that it is
not possible to memorize both FM and AM sta-
tidns into the same preset key. Memorize them
separately instead.
EXAMPLE: It is not possible to memorize sta-
tions broadcasting on FM 98.1 MHz and AM
1432 kHz frequencies into the same preset key.
Memorize these stations into separate keys.
e Last channel memory
This set has a last channel memory be-
sides the 10 preset memories.
*When POWER/STAND-BY “dy @ is
set to OFF (STAND-BY), the last station
is memorized, and when the
POWER/STAND-BY mcly switch ( is
set to ON/"| (2) again, this
memorized. station is displayed. When
the “AM” or FM’ FUNCTION key @®)is
selected, the FM or AM station is
memorized and the last AM or FM sta-
tion to be received is displayed.
e Unattended recording
lf you use this tuner for unattended recor-
L. ding, set the tuner to the desired station
and the POWER/STAND-BY “W"’ switch |
@ to the ON/” | “ (2) position. For unat-
tended recording, connect the tuner plug
to the timer (or to an auxiliary power
outlet of an amplifier connected to the
timer).
Since the reception frequencies have
been memorized by the microcomputer,
supported by the batteries, the contents
of the memory cannot be erased, even
after the power plug has been discon-
nected from the power outlet. This means
that the desired broadcasting station will
be received when the power plug is con-
nected again. (When the timer goes from
OFF to ON.)
