Restoring the Factory Programs & Defaults

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.

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

Do not spray cleaning solution of any sort onto the front panel of the DEQ230. If a cleaning becomes necessary, spray a recommended cleaning solution onto a cloth first, and use the cloth to clean the front panel.
