Flashes protector


Protet mode is a special diagnostic mode that starts when a fault is detected.

When in protection mode the unit is prevented from starting by protection circuit, so to prevent further damage.

Check the speakers and speakers wiring, a contact in speaker wires, or faulty speakers can send the unit in protection.

Try unplugging power cable for one hour or so. then connect cable back and see if you get rid of protect state. Sometimes accumulation of electrostatic charges inside circuit capacitors can kick in protect mode. In that case unplugging the unit from main for some times can get rid of electrostatic charges, and reset circuits by draining power completely.
If that was the problem, you will not get Protect when plugging back power cable.

If you do all the above and still get Protect, then there is a real fault.

In that case the unit may be disassembled and tested to find the fault.

If that is the case I suggest contacting the manufacturer at the number listed on the owners manual, or asking a quote on repair to a local technician.

Protection mode.


Hi, protection mode means either the speaker terminals are shorted or the unit is overheated the manul says fix the short (DOH!) or unblock the vents (DOH!) but if it is really an issue with the microprocessor, then unplug the unit, hold in power and the tape loop buttons at same time and plug back in, wait 15 seconds or so until the display flases about once a second and then release both buttons. I will doublecheck these are the correct buttons, but I am pretty sure (I have the manual)
