How do i set my knobsso my radio works

• This radio already has an echo board installed in it from the factory. On the bottom set of knobs, left side, over three knobs. That knob is your echo/delay knob. No need to install one. Just turn it on.

• Hope this helps.

This may help: If you take off the front of the radio (don't forget 2 screws in back!) you will notice a set of black and red wires running from the 2 AA backup batteries to the digital display circuit board. The wires plug into the board with a little white plug. If you unplug this the display will fade to nothing. If you plug it back in it will display an unset digital clock format. This seems to reset the radio, after which it should work.

With the vehicle on, turn OFF the radio. Next, Press the Volume and hold the VOLUME knob. You should see LANGUAGE on the display. Scroll the VOLUME knob until you see CLOCK SET. Pres the VOLUME knob and the HOUR will start flashing. Scroll the VOLUME knob to set the hour then Press it to set the Minutes. When you're finished. Turn off the radio, then turn it back on. When the radio is in use, the Radio Station will scroll on the display, then the Artist information, then after a few seconds (20-30), the Clock will display.

volume is to your choice I have mine 3/4 open to get over the noise in my truck.My sq is all the way left,RF gain is all the way right. Mic gain is about half . I don't use the swr knob because I have it hooked up to an external meter . Delta tune is set to the point of the click on the knob . Thats how I have mine set and it works fine for me.

Big Knob settings from left to right...
First knobset...inner turn "volume" fully clockwise
... outer "squelch" fully counterclockwise
Second knobset...both inner and outer knobs fully clockwise
Third knob...chose which mode you want to use...Am or Fm (If your radio has been modified to TX/RX CB frequencies, chose AM)
Fourth knob...chose your band (If your radio has been modified to TX/RX CB frequencies, chose band D/A)
The only other knob that is important is the high/low power switch. It selects the band from the pair chosen by the band knob. I don't know if band D corresponds to high or low, so try both settings until one works.

If you can't TX or RX with these settings either there is no one talking at that time or your radio, antenna, or cable might be defective. You should get a copy of the owners manual to fully learn how to chose bands and adjust the settings. I've given you a starting point that should work but may not be optimum for all conditions.

There are little red dots on the edge of each knob. As a starting point, try these knob positions (starting from the knob on the left)..
Adjust volume as desired.
Adjust squelch all the way counterclockwise (no squelch).
Adjust mic gain so the red dot is at the 12 o'clock position.
Adjust mic gain so the red dot is at the 12 o'clock position.
Adjust light dimmer as desired.
Adjust RF Power with the red dot at the 12 o'clock position.
Ignore talkback and clarifier for now.
Now for the 5 little slide switches...
Set all of them to the middle position.
Now you should be able to operate transmit and receive.

This is a very good radio, but there are so many adjustment knobs that you can reduce its performance if you just blindly turn knobs.
After you learn how the radio sounds and works with these average settings, play with each knob, adjusting a little and see what it does for your particular antenna setup. Do some "radio checks" with other CBers and find out what your best settings are. Also read the owners manual for guidance on what each knob does...especially mic gain (too low and you won't be heard, too high and you'll be garbled) and RF Power (to little and you won't reach out very far, too much and you'll overload local listeners). This is definitely not a beginners radio. But it is a lot of fun and will enable you to learn a lot.

you have two choices. either replace the radio. or open the radio up and tighten the 11mm set nut behind the face to restore the operation of the loose knob.

TRY........with radio on and set on "AM", hold "Clock" button about 7 seconds and let up - bringing a setup menu. Using tuning knob,scroll to "Hardware". Press tuning knob in, bringing up contrast menu. Press tuning knob in, bringing up "contrast level". Turn tuning knob counter-clockwise to "00". Brightness, dimming level should be "170". Turn radio off to exit, then adjust "Dim" button to your liking.

Phaedrus De Wolf--

To set the clock on the pioneer DEH-P2900MP Detachable face radio/CD/MP3 Player, follow the following steps in order.

Press the large round knob and hold for 5+ seconds to tuen the radio "off".

Once the radio is off press and hold down the large round knob 5+ seconds to enter clock set mode. (Note: You must hold the knob down otherwise you will just turn the radio back on.)

Now choose the < or > button next to the large knob to toggle between hours and minutes. Rotate the knob to adjust the digits.

When complete press the radio/sat button @ the top right of the stereo face.

When finished, quickly press and release the large knob again to turn the radio back on.
