Tektime - Siemens hearing aid connectivity

The connection between my Siemens CIC hearing aid and the Tektime got disconnected. I tried to connect, but inspite of repeated attempts, failed.
Do we need the help of the audiologist tech / software to connect it everytime ?
To put the question more simple way, can a customer connect the TEKTIME with the hearing aid, online ?
Your early inputs would be appreciated.
Thanks in Advance…
