PSU for Yealink Mono Screen Phones.

This 5 Volt 1.2 Amp Power Adapter is used to power the Yealink Desktop Phones with Mono Screens.

This means that it supports only the phones without colour LCD displays.

Mostly the older models and the new T31P and T33G phones are supported by this PSU.

This unit will not power the switchboard/reception phones with colour displays.
