Actually I have Rexton Cobalt16 (from Costco) very similar to pure700.
They come with a Bluetooth Remote, essentially the same as Siemens Tek.
I find this remote very helpfull, as sometime I need to change the volume and treble levels, especially in accustically dead rooms. Though, in most cases I dont need to change anything.
To reset the HA to the default/normal state, the quickest method I know is to open both battery compartments and close again. This is a bother.
With previous HA (Rexton Rivera) I could reset the HA by just pressing the program button on the remote for 3 sec.
Is there a way to do that with Tek? The audiologist asked Siemens. They said “yes” but gave instructions that neither of us understood (nothing in the user guide).
Help ONLY if you know for sure, and definitely from your experience.
