Help needed in tuning my analogue hearing aid

Hey everyone

I am in need of help in tuning my analogue hearing aid

I am 23 years old and serverely deaf in both ears since birth and only wear one hearing aid which is in my left ear.

I have worn analogues since a child, I was wearing a Oticon Personic 420 Power BTE until it broke last year and was told that it could not be repaired and was made to use digital, i hated it and my audiologist and i tried everything to make it sound analogue like turning compression off etc and i have taken so much time off work trying to get it tuned and a year later i am still not happy so last week i thought why not try and get my old analogue hearing model back as i miss the sound of analogue and i found a pair of Oticon Personic 425 Power Plus on eBay.

But i now need to tune them and i am asking here today for your help as my audiologist said she does not know the settings for it on the two dials on the hearing aid so i need to do it myself.

Here is my hearing aid:

So where do i start with the dials what direction should i tweak them with a screwdriver?

The green dial says: A-Gram
The red dial says: UCL

Here is my audio gram below

Thank you so much.

If you have your old 420, open the programming hatch and replicate the settings. That should get you pretty close to your old settings.

If not, then start with the UCL at 3/4 of the way up, set the volume to about 2 1/2 and change the AGRAM dial to one of the 4 settings and see which one sounds best to you.

I have searched the internet for the dial settings but can’t find it anywhere. Some of the more experienced dispensers may remember the dial settings.
