Hi John.
Press and hold the 'Set' button in the middle of the Panel Memories.
This will bring up the 'normal'- 'expand' page. This is where you will find page 2. Press the 'page' button this will take you into page 2 which is the 'Expand Mode Filter' page.
On this page you will see 2 lists of filter settings.
Scroll down the right hand list to the Equaliser and make sure it is set to 'on'
This should now hold that setting.

I will send you my mobile number

Regards
Peter B.
