Hello, I own a Radio Shack 5.8 GHz • Caller ID Cordless Phone, and I don't know how to erase my messages remotely? My phone is overloaded with messages and no one can call in. We i call my in to my home phone, it says "sorry the mailbox is full and it's not enough space to leave a message." Unfortunately, I don't my pin #. I bought the phone only for my alarm system. Help!
