"lost" line keys

[Flora_Yealink]

Hi Christopher,
If you select Lock from the Value field, the line keys located in the same position of the other page will be automatically assigned Line feature with Lock filled in the Value field. Then you can use this key on every page. This feature is only applicable to line key 1-9.
If you select Float from the Value field, the phone will automatically switch to the page the line key located, when the line key receives an incoming call.
If you select Default from the Value field, you can only use this key on the current page.
