Re: Pioneer DEH-P690UB FM tuning problem

Pioneer have factory set your DEH-P690UB to 0.2Mhz steps to match the American FM frequency allocations. The fix is not casual as it requires complete disassembly of the head unit and repositioning of two surface mount resistors. This will void any warrantee and unless you're good at microscopic soldering could also ruin the set. I did however void my 2 year warrantee yesterday partly out of frustration and because I have the right SMT tools at work. Now my tuner CPU thinks it's in the Austrailian/Asian model DEH-P7950UB and is also compatible with UK stations. A previously hidden menu is also available where I can set either 0.1 or 0.05Mhz stepping for FM and 9 or 10KHz for AM BSM scanning. The rotary control now steps in 0.05's instead of odd 0.2's on FM Hope this helps.

Re: Pioneer DEH-P690UB FM tuning problem

Pioneer DEH-7950UB can only support hard drives which draws current of 500mA Maximum. If your hard drive consumes more than that, it will not read the HD. However, external HDs have power adapters to compensate the power needed.

Re: Pioneer DEH-P690UB FM tuning problem

Look for a small switch on the side or top or bottom or back of the unit that will switch the frequency "jumps". You will have to pull the radio out of the dash in order to see the switch and they are usually behind a small rectangular hole and do not protrude outside the case of the unit. If you have an owners manual it will tell you exactly where this switch is. Good luck.

Unable to tune frequency in the step of 0.1Mhz in my DEH-3700MP audio system.Example if i want to tune 104.0MHz it will tune to either 103.9 or 104.1MHz.

Skipping all the technical stuff, each FM broadcast channel is 0.2 MHz wide and starts on an even number. The lowest channel for example is, 87.8MHz - 88.0MHz. Radios will tune to the center channel, ie 87.9 MHz. Any FM station in the United States is always an odd number, therefore radios in the US will never tune to an even number

Can't set the radio stations

When you find a frequency that you
want to store in memory, press one of pre-
set tuning buttons 1through 6 and hold until the
preset number stops flashing.
The number you have pressed will flash in the
preset number indicator and then remain lit.
The selected radio station frequency has been
stored in memory.
The next time you press the same preset tun-
ing button the radio station frequency is re-
called from memory.

Do not have manual. Need to program tuner channels and clock.

For clock turn key on and stereo off. Press and hold the function button for 3-5 seconds. the clock should appear with the hours flashing. Use the up-down buttons to set hours. Push the right button to set the minutes. Now turn on the stereo with the source (or power) button and your done!
Remember key on stereo off. hold function, the rest will become second nature once you've done it a few times.
Tuner pre-sets are super easy. Tune to the station you want and then just hold the # button (1-6) that you want that station on for about 3 seconds. The channel your on, (e.i 104.9) will flash a couple of times and then stop flashing. When it stops flashing it's in the memory. Tune your next channel and hold # 2,3,4,5,6, If 6 isn't enough push BAND and your on FM-2 with 6 more pre-sets, Push it again for FM-3 with 6 more presets. Push it a 3rd time for the AM band with 6 pre-sets and one more time to get back to FM-1.

My Pioneer DEH-2000MP now has the worng AM frequency spacing, ie. rather than tuning in 580AM, it tunes to 576AM and the station is fuzzy. This appears to only effect AM, not FM. Stereo worked fine until...

Get to the set-up menu by pressing the source button until just the clock is displayed, no music just the clock. Now press and hold the "func" button until "Menu" appears. Now scroll thru the various items using the up & down or the side to side buttons. I believe you will find the item for US or Europe or like Alpine reads Area 1 for US and Area 2 for the rest. Good luck.. Mark

Tuning steps/increments

Hi Benimur thanks,

What kind of mod would you be talking about and also the problem would be what part of uk hes going to that is if it is the uk hes planing on going.

Adjusting the firmware would change the frequency but is their that firmware out their for his make/model

Also what ive tried on my own stereos car and house is that fishermans frequence is like you say its 95.1 and 95.3 so its going up in .2 in odd incremants so what i tried on my stereos is the nearest frequency possible for uk stations ok.
So in uk one of our main stations is
radio 1 at 97.9 this station would be spot on
and brmb at 96.4
so if its going up in .2 incremants then 96.4 closest one on his would be 96.3 or 96.5 witch i tried and you can get this station and wont notice any bad signal even at high volume.
So for the range to be out by only .1 then i cant see their being a problem.

Even on DAB radios using manual tune instead of auto still picks up the stations with no problems.

So if your sure his stereo goes up in 95.1 and 95.3 then he should have no problems as the output from the stations is high.

Also radio 1 our main station in uk is 97.9 so his should pick up this station with no problems at all.
But please tell me if im wrong about his frequency as ive only worked with uk based systems witch are the same as europe .
Do you understand what im trying to get across.
If you think its going to cause loads of problems by being out by .1 then let me know.
If you think it wouldnt be a major problem then also let me know.

Ill wait till i here from you before i get back to fisherman as i dont want to give him information that would be no use to him ok.

Please let me know either way ok thanks and speak soon

Very weird Radio Tuning Problem

This is a USA model and by default in the USA all FM stations end in an Odd number. This is completely normal. you can try holding preset 1 and 5 down while pressing the reset button on the unit and it may allow you to switch to a Europe style of tuning.
