Telezapper TZ 900
One of the most useful gadgets around, the TeleZapper TZ 900 provides a solution to all those irritating telemarketing calls that you receive – usually during dinner.
Following on from the success of the Telezapper the Telezapper TZ 900 is a slimmed down version with built-in battery and a three-tone mode.
It works on the simple principle that 90 per cent of telemarketing calls are placed by computers and use a predictive dialling technology. When the phone is answered, the Telezapper TZ 900 emits a special tone that tells the computer that your phone has been disconnected. As disconnected numbers are automatically removed from the call lists of Telemarketing companies, you’ll receive noticeably fewer calls. It’s as simple as that!
For newer dialing systems, the TZ 900 has another trick up its sleeve to fool the telemarketer, with an advanced three-tone mode that can be easily accessed via a switch inside the protective case. Normal calls should be not be affected unless they use the same dialling technology. Installation is quick and simply requires the Telezapper to be plugged in to the phone line. The built-in battery will probably last for the lifetime of the product.
