Ranger AR3500- Frequency Mod Question

[fantasma25]

Good afternoon,
So, I got a Ranger AR3500 previously used, turns on, scans etc. I took it apart and I see that someone already did the frequency expansion modification (has the connector across the 3 pins), however when I turn it on it only shows the regular 28-29 frequencies. Is there something else that I should be doing to access the 2400 to 29.999 frequencies?
Thank you in advance.

Try resetting the CPU.

Thank you, I've looked around for instructions on how to reset it but so far I am coming up empty handed. By any chance do you know how or maybe point me in the right direction.

Thank you!

Here are a couple of links that may help:

Thanks!
I did check those earlier but saw no reference to resetting the cpu. I will continue looking.
