Region problem Hi I have problem , I need to change the unit to region 2 from region 1 (dvd) and the frequency, step from 200khz to 50 khz (tuner) please help me . benny DNX 7120

Question edited for clarity.

Make sure you got the correct transducer Your model comes in single frequency and dual frequency. Make sure the connection on the back of the unit is good and you have no corroded or missing pins. Make sure the software is up to date.

Hi, Your post/description "the frequency increases in steps of .2 Mhz or 200Khz" refers to the increment of frequency spacing between tuning steps and is largely dependent on the radio standards of the country/region the radio is intended to be used. Assuming no hardware fault to the radio, tuning steps may be adjusted by: 1. With the radio switched off, press the Step/Band button for about 2 seconds. This will display the current FM tuning step (200Khz as in your case); 2. With the radio switched off, press the Step/Band button for about 10 seconds. This will display FM and a blinking 50Khz with a single beep sound. By rotating the Tuning Control you can increase or decrease this value. 3. pressing the Step/Band button again will move you to the tuning increments of the AM band again adjustable via the Tuning Control. 4. pressing the Step/Band button again will save the setting and complete the process. Hope this be of some help. Good luck and kind regards.

mine does the same thing. I found a pdf of the manual and it said this in the troubleshooting section:
""PCM--kHz" appears on the display. , The sampling frequency is more than 48 kHz. Change the DVD setting to 48 kHz."
I have my seiki tv hooked into the dvd/ld input through a coaxial cable, and I don't think my tv has a setting to change the sampling frequency. so I have no idea what to do. any help would be great!

Try powering the unit up while holding the Set/MHz button. I did that and it restored the display (and the rest of the radio's operation) back to normal.

The character codes are test-mode displays that correspond to frequencies (in MHz):

A0001-A0640 - 136.000-143.9875 in 12.5 KHz steps B0001-B0400 - 144.000-147.990 in 10.0 KHz steps
C0001-C2081 - 148.000-174.000 in 12.5 KHz steps

I haven't the foggiest idea why this isn't in the manual somewhere, or at least flipped back to normal by a two-key or three-key reset. 73, k2mct

You can switch the AM band tuning steps between 9 kHz and 10 kHz.

The initial setting is 9 kHz. Please set the AM tuning step frequency to match the AM band tuning step frequency in your area.

USA and Canadian models 10 kHz

Other models 9 kHz

Press MEMORY while holding down TUNER.
Note: All the preset stations are erased when you switch the AM band tuning steps.

Im not familiar with your particular unit but you should be using a low frequency transducer for water over 500'; something like a 50 kHz transducer or a dual frequency transducer like a 50/200kHz for detail with the high freq. but increased depth range on the lower frequency. As far as setting it to 250 ft, you should be able to use the range feature and adjust the maximum to 250'. typically the factory default is automatic so it will caonstantly adjust the range based on the maximum current depth.
