## Questions & Answers

**Q: Is it possible to turn off the new "auto save to whitelist" advanced feature so it is a pure whitelist blocker?**
A: No way to turn off the "auto save to whitelist".  Unfortunately sometimes unwanted callers do press "0".  I had mine setup for 2 or 3 days when one of the computer support scammers dialed 0.

**Q: If a new caller presses zero will he be able to leave a message on my answering machine?**
A: Yes,surely,it can work.For since the new caller presses zero,their calls were added to white list forever.And at this time,if you don't pick up the message.Then caller can leave a message to your answering machine as normal.

**Q: Any products with - contacts go through, non contacts go to answering machine, blocked #'s get hung up on?**
A: I would also like such a new product. It could just trick the phone answering machine to answer with 10 fast rings or such. That would also say don't answer to me. I hope they create it soon, I have #1 and buying #2 and will buy your version when they make it.

**Q: Versions 1 and 2 look alike.  How does one tell the difference between these 2 units?   Is there a model number or version # printed on the units?**
A: The photo on Amazon for the Version 2 is actually showing a Version 1 which adds to the confusion. There are three identifiable differences between the models.  1) Version 2 does not have the Sentry symbol before the Sentry label on the device.  2) Instead of the language labels under the VOICE button, version 2 has A/B/C/OFF.  3) When turning over the device, version 2 has a battery compartment while version 1 does not.
