Front Panel Controls and Status LEDs
Operating the RC-610
FEATURE NAME WHAT IT DOES
Status LEDs DELAY INACTIVE Indicates that the 610 has been
forced into a bypass state. This can
happen automatically as a result of
the EXIT DELAY function or manually
as a result of moving the STATUS
button on the front panel of the 610
to the BYPASS position.
DELAY ACTIVE Indicates activation of the START
DELAY function.
3.5 SECONDS Indicates that 3.5 seconds of delay
has been built into the program
audio.
7.5 SECONDS Indicates that 7.5 seconds of delay
has been built into the program
audio.
Push Button Controls EXIT DELAY Initiates the gradual reduction of
delay time. Several minutes before
the end of the show, press this
button to have the Symetrix 610 time
compress the program audio until
there is nothing left in its memory
(zero seconds delay). At this point
the program is back in “real-time”
and the 610 automatically removes
itself from the signal path. This
button blinks as long as delay time is
decreasing. Its light switches off
when zero delay is achieved.

Operating the RC-610
Front Panel Controls and Status LEDs continued
FEATURE NAME WHAT IT DOES
Push Button Controls continued START DELAY Initiates the gradual increase of delay
time. Press this button when a radio
talk show begins. The light of this
button blinks for as long as delay
time is increasing. The light shines
steady once full delay time (7.5
seconds) is achieved. See Appendix C
in the Symetrix 610 Broadcast Audio
Delay User’s Guide for more informa-
tion.
COUGH Mutes the incoming signal while
allowing the output signal to play
(uninterrupted) from the 610’s
memory. You can cough, have a
quick drink of water, or make a
comment to the producer or engineer
without any perceptible program
interruption.
When you press this button, the 610
plays from memory. If you press this
button for a period of time that
exceeds the amount of delay avail-
able, then there will be dead air for
the excess (muted output). When
you release the button, the 610
automatically begins to refill the
memory.
DUMP PROFANITY Plays delayed programming stored in
memory to prevent unwanted audio
from reaching the airwaves. As the
program begins, the 610 gradually
and unobtrusively delays or
“stretches out” the program until 7.5
seconds of stereo audio is stored in
memory. When you press this button,
the memory is cleared. Then the 610
automatically begins to stretch (time
expand) the program audio again
until it attains the full 7.5 second
delay.
See Appendix C of the 610 Broadcast
Audio Delay User’s Guide for details
on how to select between a full memory
dump or a half memory—3.75 second
—dump.

Following are the terms and limitations of
the Symetrix warranty.
Warranty

the Product will be free from defects in

the additional limitations set forth below)
for an additional four years if the Warranty
Registration is completed and returned to
Symetrix (or completed online) within
thirty (30) days of the date of delivery.
Symetrix’s warranty obligation is limited to
the repair, replacement, or refund at
Symetrix’s sole discretion, of the part or
parts of the Product which may thus prove
defective in materials or workmanship
within one year from date of purchase (or
five years from the date of purchase if
Buyer has registered its purchase as
provided above) under normal use and
which our examination discloses to our
satisfaction to be thus defective, provided
that Buyer gives Symetrix prompt notice of
its warranty claim and satisfactory proof
thereof.
Symetrix will make every reasonable effort
to ensure that parts are available to
support the repair of our products under
warranty. In the event that a product or
component part thereof becomes obsolete,
unavailable or irreparable, Symetrix
reserves the right to refund a prorated

satisfaction of all warranty claims. A refund
of the purchase price is prorated as
follows: 100% through year one, 80%
through year two, 60% through year three,
40% through year four and 20% through
year five.
In order to serve you better we request
that the Buyer shall, prior to shipping

your Product and process your warranty
repair as quickly as possible. Buyer will
