Wait a moment to ensure there is no residual charge left in the base station.
On the back of the base, press and hold the reset button (the small black button located near the
tiny white DIP switches). NB on the SDW series headsets there are 2 buttons; S1 and S2. You’ll

reconnected, you may release the reset button.
The base station should now carry out a reset
