CPR V5000 Call Blocker

CPR V5000 Call Blocker. Very easy to use. If you are at the phone the call blocker is attached to, just hit the red button. From any other phone hit #2 while ringing and it will block the call. Easy to unblock a number if blocked by accident. No longer need as we no longer have a house phone. Link below is for the user manual. Great condition. From a smoke free home. https://www.callblockerusa.com/pages/instruction-manual?srsltid=AfmBOooKd7Pzze0W2L5lR43N25GYqPxmaUyGnQdoS1URhzsVQfWs_FeC
