Pioneer deh-p750 locking

Mosfet 50wx4 indicates a feature of the Pioneer car radio. It isn't a model number. One Pioneer car radio/CD player with this feature is the DEH-1500. On this model, you need to turn off the unit to set the clock. Press and hold the Source button (to the left of the preset tuning buttons) until the device turns off. Press Audio (upper right corner) repeatedly until the clock appears in the display. Use the arrow keys (Skip/Back or Left/Right) on the right hand side of the radio to select a segment of the time to adjust. Use the Up/Down arrows to set the current time. Repeat choosing the time segment and adjusting the time until both the hour and minutes are correct. Press Band or press and hold the Audio button to exit the clock setting mode.

ManualsLib has the manual for the Pioneer DEH-1500 here: https://www.manualslib.com/products/Pioneer-Deh-1500-Car-Cd-Player-Mosfet-50wx4-Super-Tuner-3-Am-Fm-Radio-3432555.html . See page 16 for the clock setting procedure: https://www.manualslib.com/manual/129844/Pioneer-Deh-1500.html?page=16#manual . See page 6 for the picture of the front-panel buttons for the DEH-1500.

I hope this helps. Please add a comment with the model of the car radio if the above procedure doesn't work for your unit.

Real Answer to set Clock on Pioneer DEH-6 AM/FM/CD car player - DEH-6 will have no FUNCTION button.
1-Press SOURCE ("SRC" - button left of "1") and hold until unit powers off.
2-Press AUDIO ("A" - button upper right) and hold until clock appears in display.
3-Press </> arrows to select hour/minute to set - numbers will blink.
4-Press up/down arrows to increase/decrease hour/minute.
5-Press "BAND" or press "AUDIO" ("A") until unit powers off.
6-To check: Press CLOCK to turn on new clock setting display.

you can seek to a station you like and then choose a preset button 1-6 . press the chosen preset button for a few seconds until the display blinks. the station should then be locked into that preset.

For most Pioneer single CD players, you can set the clock using the following steps:

1. Press and hold the SOURCE button until the unit turns off.
2. Press and hold the FUNCTION button, until display pops up, then release. (If you do not have a FUNCTION button, then push the AUDIO button)
3. Press the FUNCTION button again until the clock shows on the display.
4. Press the UP and DOWN buttons to adjust the hours.
5. Press the LEFT or RIGHT arrows to move to the minutes.
6. Press the UP and DOWN to adjust minutes.
7. When complete, press the SOURCE button to exit.
Hope this helps!!!

The solution that worked for me is:

1) turn off the radio.
2) Push and hold the power button down (the dial). DON'T release the button.
3) The unit will display the time on the lcd screen with the numbers flashing, (only hr or min).
4) use the up/dwn, right/left buttons to set the clock.
5) turn off the unit by pushing the power button (again, the dial).

That is it. the clock should be set.

Hope that helps,

Here's a link to the manual Pioneer's web site.

Here's how you set the time (from page 16 in the manual):

1: press SOURCE and hold until the unit turns off.
2: Press AUDIO repeatedly until the clock appears in the display
3: Press (left arrow) or (right arrow) to select the segment of the clock display you wish to set (hours, minutes)
4: Press (up arrow) or (down arrow) to set the clock.

- To cancel clock settings, press BAND
- to save clock settings press AUDIO until the display stops blinking

Same as all Pioneers. With the car on or in ACC position press and hold SOURCE until the radio turns off. Press and hold FUNC to enter the menu. Use the four arrow keys to navigate and make changes.

Found a posting on another site from 2005, and it worked!
Turn on the radio. Press and hold the "Source" button until the radio goes off. Press and hold the "Audio" button until the numbers flash. Use cursor/arrow buttons to adjust the time. Press and hold the "Audio" button to exit.
