When you say you turn if off and on, do you mean turning the detector off and then on? Or the function itself?
I'm a little confused what you mean: "I found from settings "standard, discriminate", and custom options it once it seemed to me it changed to what i wanted but when i turned it off and back on again sounded the same, and and was still on the discriminate option, and sounded again the same after i took all the others just nothing changed. do you think it is a malfunction?"
Are you talking about changing the tones for your targets in the audio section? I see options "Standard", "Shifted" and "Custom" in the VDI tones selection section. You do need to have ToneID checked in the audio mode you are using (discrimination, Mixed Mode, Stereo Mixed Mode) for the VDI tones to work. And then you run it, it's working. You turn the machine off, then back on, and the settings have gone back to default? Am I close?
If I'm close to understanding your statement, do the following test. Change the state of the Tone ID option, turn the machine off and then on, and see if the toneID option is the same as you had just set it to, or if it reset back to what it was. If the setting did not stick, I would give White's a call and explain what you're seeing.
As a note, when you switch programs, the settings may not be the same in the new program as the one you switched from. The detector should be saving the settings for each program that you modify. And when the machine is powered down, these settings for all programs that you changed should be stored. But a setting change in one program will NOT change the same setting option in another program. Just the one you are currently in.
