Well, if APH tech support says that it's not a big issue, I assume that they know what they're talking about. Ten second increments are nothing and I'm not losing any sleep over it. ----- Original Message ----- From: "Dan Keys" <dnkeys@xxxxxxxxxxxxx> To: <bookport@xxxxxxxxxxxxx> Sent: Wednesday, November 29, 2006 2:03 PM Subject: [bookport] Re: Book Port Observation Hi, I guess my whole point was this. Even with the Beep turned off, the unit is still draining batteries if keys other than the 1 and 3 are pressed. Because if a key is bumped the unit switches on for 10 seconds and then turns off. If you do this enough, it certainly will drain the batteries.
