Introduction

The Uniden EXP 7900 Series 900 MHz cordless phones are designed and engineered to exacting standards for reliability, long life, and outstanding performance. The EXP 7900 Series features include AutoTalk and AutoStandby. AutoTalk allows you to answer a call by just removing the handset from the base so you dont have to waste time pushing buttons or flipping switches. AutoStandby allows you to hang up by simply returning the handset to the base. The EXP 7902/7904s Voice Scramble protects your privacy by scrambling any call you make or receive. The RF signal between the handset and the base are changed, making it difficult for someone to clearly intercept your phone calls. The UltraClear Plus true compander circuitry virtually eliminates background noise. This innovative technology, together with 40 different channels, provides you with the best possible reception during all your conversations. To protect you against misbilled calls which might result from your phone being activated by other equipment, the EXP 7900 Series has Random Code digital security which automatically selects one of over 65,000 digital security codes for the handset and base. Also, the AutoSecure feature electronically locks your phone when the handset is in the base. To get the most from your phone, please read this owners manual thoroughly. Also, be sure to complete the product registration form and mail it in. Be sure to visit our web site at: www.uniden.com. 2
