HMm; We are accustomed to looking only at the Costco models for Philips (HearLink 9050, HearLink 9040, HearLink 9030).
You can use the help feature on Philips HearSuite (Help / Open help files / Cables and adapters). Though that is just general help for Cables and adapters. What we really need to find out is the connection options for this MI3 PR (RIC/RITE) style hearing aids.
Sometimes connecting hearing aids can be tricky. Have you read the steps/checklist in "How to connect the Fitting Software to your Hearing Aids" in a DIY School Hearing Aids PDF File named (Noahlink Wireless - DIY Users Guide)?
Meanwhile I will look for specs on Philips MI3 PR (RIC/RITE).
