8Front Panel Buttons And Display
Power Button
Press the Power button once to turn the Model 5250 v.2 on, press it again to turn it off. The Power button is inoperative when the Turn On Options switch on the rear panel is set to Audio or 12V.
Protect Indicator
The Protect indicator will illuminate red if the Model 5250 v.2 experiences an external fault condition and the unit will stop playing. This prevents possible damage to the unit from continued operation. Examples of external fault conditions are short circuited speaker wires, excessive heat, and trying to drive too many speakers at high levels.
If Protect is illuminated you need to locate and correct the fault; for example, remove the short circuit, let the unit cool down, check the load impedance and lower the volume level. To reset the protection circuit you need to turn the unit off.
Turning it off:
•Turn On Options switch (on the rear panel) in the Man position: press the Power button on the front panel.
•Turn On Options switch in the 12V position: turn off the 12V trigger source; the 5250 v.2 will turn itself off right away. You can also turn it off by unplugging its AC power cord.
•Turn On Options switch in the Audio position: turn off the preamplifier, surround controller or system controller that dri ves your 5250 v.2. You can also unplug the 5250 v.2’s AC power cord.
Note: It requires approximately 10 minutes after removing the audio source before the 5250 v.2 turns itself off. If you don’t want to wait and you have access to its AC cord, simply unplug it. Leave it off and/or unplugged for awhile to cool down and you’re confident the fault is corrected. If you unplugged its AC power cord to turn it off, plug it in again.
