Restoring the Factory Programs & Defaults
There is a power-up button combination that will restore the
DEQ230's User programs to the factory default programs. This
same combination of buttons will reset all of the Setup
functions to their default values. This procedure is called
"reinitializing."
To reinitialize the DEQ230, follow these steps:
1. Make sure you really want to erase every program you have
stored. That is what reinitializing the unit does.
2. If you haven't already done so, turn off the DEQ230.
3. Turn the unit on while pressing the [DOWN/UP] buttons.
4. When you see the word "RESET" in large letters over the
[BAND SELECT] buttons, you may let go of the
[DOWN/UP] buttons. After a couple of seconds, the DEQ230
will return to Program mode.
Line Conditioners and Protectors
Although the DEQ230 is designed to tolerate typical voltage
variations, in today’s world the voltage coming from the AC line
may contain spikes or transients. These can cause audible noises,
and they can stress your gear and, over time, possibly cause a
failure. There are three main ways to protect against this, listed in
ascending order of cost and complexity:
• Line spike/surge protectors. Relatively inexpensive, these are
designed to protect against strong surges and spikes, acting
somewhat like fuses in that they need to be replaced if they’ve
been hit by an extremely strong spike.
• Line filters. These generally combine spike/surge protection
with filters that remove some line noise (dimmer hash,
transients from other appliances, etc.). A good example is the
Isobar™ series from Tripp Lite.
Care and Maintenance
Cleaning
Disconnect the AC power supply, then use a damp cloth to clean
the DEQ230’s metal and plastic surfaces. For heavy dirt, use a
non-abrasive household cleaner such as Formula 409™ or
Fantastik™. DO NOT SPRAY THE CLEANER DIRECTLY
ONTO THE FRONT OF THE UNIT AS IT MAY DESTROY
THE LUBRICANTS USED IN THE SWITCHES AND
CONTROLS! Spray onto a cloth, and then use the cloth to clean
the unit.
WARNING! Following the
p
rocedures in this section

to do before going through
these steps.
