SUDO mode after connecting 101 and 102 together

I get this message after connecting the 2 modules together. No pendulum, no led lights etc.
101 is C series, 102 is A series. Is there anything i should do to work them up? Firmware update etc?
I have bought them separately.

Thanks and Merry Xmass!

Hi Jurek

Please move the STORAGE switch on the ER-102 from admin to user. See the last page of the ER-102 manual for an explanation of the admin mode.

Kind regards
