To open the unit, four T6 screws have to be unscrewed. Do not use the torque driver for this, because torque drivers are mostly designed for fastening and not for unscrewing the screws.
Hold the unit with the volume key against the table. Hold the A-Cover with your left hand and then grab the B-Cover to unlock the side snaps in the bottom area.
Before loosening the upper snaps of the cover, be sure that you press the module against the A-Cover. The module is still fixed with the A-Cover with one hidden screw in the antenna area.
There are three clips, which have to be released. Be careful when pulling the covers apart in the antenna area. It is easier if you wobble the covers carefully against each other.
Now you can take away the B-Cover. Be careful not to damage the antenna, which can break if you try to rotate the cover against each other.
See the screw, which fixes the antenna and holds the module inside the A-Cover.
Do not touch the antenna with your fingers. The fingertips would cause corrosion to this sensitive material.
Lifting up the CMT module is very easy now. Protect the display with a foil.
Four clear plastic clips hold the UI module on the CMT module. Unlock these clips when you need to remove the UI module.
Never touch the pads with your finger to avoid corrosion.
If you want to remove the speaker or buzzer, do not grab the items at the spring contacts.
