Re: Turns off immeaditally after turning on

These units are designed in such away they are very suseptible to power surges, Brownouts. And a lot of times they just stop working through no fault of the user. A transisors or capacitor fails and the unit just does not work properly and goes out. The issue is generally the unit is priced so if you took it to a repair shop it would cost between $50 to $100 Dollars to repair. If they can get the parts to repair it or if it can even be repaired cost effectively.

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on; or it may turn on but produce no audio to the speakers.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'nekkid'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

My Aiwa cx-nma545 keeps turning off.

Your system is in 'Eco' mode. If you are in this mode, and go 10 minutes without playing a CD or cassette, it will automatically turn itself off.

Here's how you get out of 'Eco' mode:

1) Go to the jog wheel assembly
2) Press 'Eco'
3) Press 'Enter'
4) The display will show "Eco Mode On"
5) Immediately turn the jog wheel, to turn the status from 'On' to 'Off'

Radio turns on at midnight automatically, I do not have manual to unprogram this

To shut off the timer function (turns the unit on at a certain time):
Press the timer button (on the system itself) until the little clock icon disappears from the units display. This deactivates the timer.
Alternatively, you can reset the system to factory default (clear all user inputs and setting from memory)by:
Start with the power on
Turn the unit of using the power button.
Turn the unit on while pressing the Stop/Clear button.

Here is a link to a PDF version of the manual free to download:

How can we turn off the automatic start of Radio or CD setting?

The activating and deactivating of the 24 hour timer is via a toggle button, labeled "TIMER" on towards the right side of the top console. When the TIMER is activated, you will see a small clock symbol on the LCD display. While the unit is on, tap the TIMER button once. The clock symbol will disappear and the timer is now off.

Reactivating the timer is the same process (remember, the button is a toggle). Tap the TIMER button and you'll see the timer settings show up on the display (time on, time off, source, and volume). The little clock symbol appears again.

Good luck!
