Hi there and welcome
Then phone is an extension handset that works with the Base unit. The manual is the for the base unit which covers your phone as well.
It is not possible to send a printed copy but I have the link for you below which is the electronic version
With it open, if you press CTRL + P or CMD + P on a mac, you can then print it
If you would like any additional information or assistance, please do not hesitate to let me know.
Else if you can take a second to rate my service by clicking one of the stars at the top of the screen then submit, that would be greatly appreciated.
