[TenTec] S-TONE LEVEL ANNOYING

[George]

I have an Orion-2 latest FW version. 
Is there any way I can rectify the side tone level from the speaker to head phones. When I am on head phones it is comfortable at 77 and when on speaker it is comfortable at 18????
I would think there should be a balance one could make to rectify this large disparity in level?
Has this been covered before? Does Ten Tec know of this?
Thanks.
George
