Adjusting Volume on the LG Aria 7024 – The LG 7024 is typically the receptionist handset or primary phone. It is very similar to LG 7016 in that it utilises navigation keys and the 3 menu keys.
The 24 buttons on the right hand side are flex keys. This means you can program them to do what YOU want. For example, you might prefer to see incoming lines, for personal speed dials, or perhaps display other staff in the office. The choice is yours and each handset can be tailored for individual staff members.
