Tested and initialized. This is a simple, easy-to-use telephone. I replaced and installed it 2-3 years ago, but I rarely used it, so it's in pretty good condition. There are, of course, no problems, but I am selling it because I canceled my landline service. There is no extension handset. The set includes the main unit, power adapter, and modular cable. There is no instruction manual, but you can find the electronic manual by searching for the model number "VE-GD27" on the internet. It will be waterproof-packed and wrapped in bubble wrap, etc., and then shipped by free, anonymous delivery.
