50. CHECK key: This key toggles the MEMORY display
between the contents of MEMO 1 and MEMO 2. The
corresponding indicators will light to show which one is
being displayed.
The MEMO points are basad on the counter readouts
and the counter is
based
on revolutions of the cassette
hub. The MEMO points are subject to variations in tape
pack. Slight drifting of
8
cue point after a number of
fast wind operations is normal.
51. LOC 1 and LOC 2:
Pre8sing either of these keva
causes the tape to roll (In either F.FWD or REW) to the
corresponding MEMO point.
While fast winding, the
MEMO indicator will flash in the display. The tape will
stop when it reaches the MEMO point.
If PLAY Is
pressed while the tape is locating, the 688 will
automatically enter Play mode after reaching the
memorized point.
When the tape overshoots the memorized point. it will
roll back at Slow Play speed, stopping at. or if PLAY
has been pressed, 8tarting playback from
the
memorized point. Don't hit PLAY during that Slow Play
interim.
48. COUNTER display with the RESET and TRT switches:
(As for the MEMORY display, refer to #49 and 50.) The
4·digit COUNTER display has a double function.
11 When the
6sa
is first turned on, the COU NTER
switches to its normal tape counter mode and displays
"0000" (not 00:001.
2) Pressing the "TRT" (Tape Run Time) switches the
display from COUNTER mode to TRT mode. as indicated
by a colon ":" in the window.
NOTE about TRT mode:
• The maximum readout time is 59 minutes and 59
seconds (displayed as 69:59).
• Unlike the normal COUNTER mode which counts tape
motion in both forward (RECORD, PLAY and F.F\N,D
modes) and reverse (REW mode) directions, TRT mode
counts only in RECORD and PLAY modes.
• The TRT display Is calculated from the capstan motor
and will not necessarily be accurate with elapsed time
as read from your wrist watch or wall clock.
Both the COUNTER and TRT modes are active at the
same time. Therefore, switching the display from one
mode to another does
not
disable or reset the
previously displayed readout.
You can switch
COUNTER display modes as often as needed and the
readouts will not be cancelled or reset to "0000".
RESET switch: This switch has effect only on currently
displayed readout
When the 688 is turned off, both
the displayed and hidden roadouts are reset,

AUTOlOCATOR SECTION
49. MEMO 1 and MEMO 2:
These keys are used to
establish two. autofocation points in the 688 memory
system, They can be used while the tape is stopped or
rolling.
Pressing either key at any point on the tape
loads the current tape counter number into that
memory register and into the MEMORY display. Esch
time the key is pressed, a new MEMO point is
established, erasing all previous memories in that
register.
"MEMO 1" or "MEMO 2" will light in the
MEMORY windows to show which location Is currently
being displayed. Both MEMO points are erased when
p,ower ;s turned off or when a cassette tape is ejected.
The MEMO points will not move even if the Zero
position Is changed by the RESET key (#48).
For
example, if MEMO 1 is pressed at counter "0155" and
RESET is afterWards pressed at "0160", then the 688's
memory system will calculate where the "0165" point is
with respect to the new Zero position and display the
MEMO 1 point as "0005",
~
..., .

If so, the tape may be blocked. If this happens by
accident. defeat it by pressing STOP.
52. RTZ fRetum to Zero); Pressing the RTZ key will cause
the 688 to fast wind the tape to the COUNTER "0000·
point on the tape.
53. REPEAT: The REPEAT function provides a "Playback
Loop· or -Block Repeat" between the two programmed
MEMO points.
Note that MEMO 2 does NOT have to
be
8
number greater thlln MEMO 1. When REPEAT Is
enabled and the current counter number is between
the two MEMO points, the tape wlll play to the higher
MEMO location, rewInd to the lower MEMO location
and
start
over.
To disable the REPEAT funetlon, press the REPEAT key
again. The REPEAT indicator will be turned off.
DurIng REPEAT e:1I the transport keva are IIctiva: If. you
fastwind the tape out of the loop, the REPEAT indicator
will blink showing that If you want to resume the
repeat you have to go back to a point within the loop.
Pressing LOC 1 and 2 will resume the repeat
If the
tape is at a point lower than the START point. pressing
PLAY will normallv start playing, and when the loop
end is reached it will rewind to the start point to
resume the repeat.
In actual Recording, the REPEAT function will not
activate,
even if the REPEAT indicator i8 on solid. The
688 will continue recording after the higher MEMO
location.
