Not only does this handy gadget screen telemarketing calls for you, it also helps to ensure they won't keep trying to get ahold of you. The TeleZapper from Privacy Technologies plugs into any phone or phone jack. It works by emitting a special tone that makes your number appear disconnected to computer-generated calls. Eventually, as your number is eliminated from lists, the calls become a rarity, rather than routine. It won't interfere with manually dialed calls, answering machines, voicemail, Caller ID or Call Waiting. However, it may remove your number from the lists of organizations that use dialer computers. Easy installation. No monthly fees or service charges. AC adapter and phone cord included. Charcoal gray. No. TZ 900. Imported. 3Hx7Wx5D".
When you've had your dinner interrupted by a telemarketer one too many times, treat your phone line and yourself to the Telezapper TZ 900. It's a simple, one-time-cost solution to the problem of annoying telemarketing calls. Based on the enormously popular classic Telezapper, the newer Telezapper TZ 900 offers the advantages of a slimmer profile, built-in battery power, and an advanced three-tone mode.
Here's how it works: Given that more than 90 percent of telemarketing calls are placed with computer assistance, when either you or your answering machine answers the phone, the Telezapper emits a special tone that tells the computer your number has been permanently disconnected. Telemarketing companies that use automated dialing systems typically remove disconnected numbers from their calling lists, and as your phone number is eliminated from more and more telemarketing lists, you'll notice fewer calls. Of course, not all telemarketers use predictive dialing systems, and those that do will undoubtedly continue their work to evade the Telezapper, but it can be a partial solution.
Most predictive dialing systems will be fooled by the Telezapper's standard single tone. However, for newer dialing systems (presumably designed in response to the success of the previous Telezapper model), the TZ 900 offers an advance three-tone mode. To change the mode, unscrew and remove the protective case and then slide a recessed switch. (We suggest that Privacy Technologies put the switch on the outside for their next model.)
For the most part, regular callers are unaffected by the Telezapper, but it may "zap" calls from other organizations that use the same predictive dialing technology (such as charities, pollsters, and automated emergency weather systems) and from callers who use certain types of calling cards. (For more information, click FAQ, or frequently asked questions, in the left navigation bar.)
Installation takes seconds. Just plug the Telezapper into your phone line and your phone into the Telezapper. It's that simple. A built-in lithium-ion battery provides power and will likely last for the lifetime of the unit. The Telezapper includes a phone cord and instructions. Privacy Technologies backs the device with a one-year warranty. --Mike Brown

First: As I had expected from reading most of the recent reviews, my unit's battery was DOA: Its so-called '3 Volt' battery measured just 0.6 volts, This is the obvious result of these units having sat on a shelf somewhere for a number of years AND THE SELLER IS MOST CERTAINLY AWARE OF THAT You'd think that the very least they could do is pack in a new battery with the the shipment, if they're too damn lazy to replace it in the unit themselves.
The battery is easily changed out with a new one, and since you're gonna be stuck replacing it yourself, you'll need a small 'jeweler's' size phillips screwdriver to remove the backplate screws, then slide out the old battery and slide in the new one.
OK - Secondly: the "basic" setting for the tone programming only produced the tiniest short fraction of a tone (about one thousandth of a second) certainly not enough to be detected by a SIT Signal call-canceling sensor. So I had to select the 3-tone 'advanced' programming option, which is loud and somewhat annoying when you're picking up the phone on a legitimate call.
And Thirdly:I couldn't get the unit to generate the tone on an unwanted incoming call, except to having to pick up the phone off the hook, which then creates the tone, and then quickly hanging up again.
So The old adage "You get what you pay for" ALMOST applies here, if the seller would only give a damn about sticking you with someone's old stock,(which they no-doubt bought for a song - or inherited free) and are still too cheap to even replace the friggin' batteries.
Combined with the Do Not Call list (ha!) and our policy of not answering calls with blank caller ID - or caller ID that says anonymous, blocked, unknown, unavailable and so on - this greatly reduces the annoyance calls.
Still left to be seen if it actually works as advertised but the CR2032 battery that powers this device was DOA. Luckily many devices take the same battery so I had spares on hand. I guess the manufacturer didn't want to spend the money to use an Energizer or Duracell battery and used some cheap knockoff brand that didn't hold up during storage.
Once the battery was replaced, it emits the tones as expected. Now only time will tell.
BTW, this device is installed with the MagicJack USB device so no computer necessary and cheap annual renewal vs. regular monthly phone charges. Phone still works well with device inline with base station.
I'll give it a month and update the review as necessary.
I emailed vendor they responded by saying only that they had operated the device prior to shipping ,However,that did not address telling me what to expect the device to do and how to route the line into which? End? There was no
instruction on what position ,of two CHOICES ,the toggle switch should be in.AMAZON should require sub-vendors to include a photo copy of hand written instructions on refund
item's.Who can be smart enough the know this information. It helped me to have previously
owned a tele-zapper I bought new some years
ago so I had some clues but was not sure how to install..Please fix this. (Theo&xxxxx
When I originally purchased this, it was in desperation: I was getting at least 25 nuisance calls a day and often many more. Plugged this gadget in, and after a week the call volume dropped in half. After a month, it was down to a couple a day. I then set the switch in the back to "advanced" at that point and let it continue to do its thing. It doesn't stop 100% of the calls, but if you are really going nuts from the ringing phone, then it will work well enough to get your sanity back.
