To insert the new button cell type CR 1220 3V, hold the glasses
horizontally as shown in the picture and position the button cell
loosely on the button cell holder; plus contact facing up.
Press the button cell carefully and with extremely little force into
the button cell holder until it clicks into place and cannot fall out.
Please note that too much pressure could damage the glasses.
Finally, place the glasses upside down again on a smooth
surface. Hold the glasses by the housing and position the plug
over the button cell in the recess. Then, gently and with only
slowly increasing pressure, push the stopper into the opening as
shown in the first picture.
