Danalogic Wireless and Phonak Roger Pen

I was "upgraded" to Danalogic iFit C81W a couple of months ago. I started a new job and was having major difficulties with communication so applied for the first time for Access to Work. During the assessment, it was agreed that I would benefit from Phonak's Roger Pen and a couple of other accessories. Today I went to the hospital for one of my hearing aids to be repaired. Speaking to the audiologist, he mentioned that given the Danalogic are wireless, there is no need for the Roger receiver. Is that correct? I have searched high and low, information is really scarce about Danalogic hearing aids!
