I bought the portable pack and ice transducer to use my 597 on the ice in flasher mode.
When you power it up it will say “Transducer not connected”
Here are the steps to get it setup…
1.Power it on and when the blue opening page comes up press the menu button.
2. A green screen will come on, scroll up to normal and tab to the right. This will take it out of demo mode and you’re good to go.
To avoid doing that everytime you go out you need to disable the demo mode.
To do this-After you’ve done the above steps hit the menu button twice.
Scroll over to setup
Scroll down to demonstration which will be turned on, just shut it off and you’re good to go.
Hope this helps people going this route
