Wondering if there is any fix for my MX3000. About 75% of the time when I wake up the unit (by tapping on a key/screen - I have the pickup option off), the unit momentarily wakes up and then a few seconds later it goes off. A second wake up is always required to start the unit. Same if I have the pickup option on. Now, if I happen to try and push a button during this first wake up, the unit sometimes locks up which requires a reboot. I've tried to get in the habit of waiting for the second wake up, but wonder why my unit does this. My MX3000 is from one of the first batches that was produced in 2004. Thanks. SJ
