Caution
1
Always use only the extraction tool recommended by the plug
manufacturer of your choice. It is possible to cause severe damage
on the receptacle if a third-party extraction tool is used. For
example, using an I-PEX tool on a HIROSE plug has been known to
lead to connector damages.
2
It is very important to keep the extraction tool at a vertical position
at all time, and apply only vertical pulling force on the tool. Applying
a non-vertical force or using the tool in a crowbar style will damage
not only the antenna connector but also other components in
proximity.
