Wireless rf key finder

Introduction
The J-Tech Digital JTD-KF4F key finder can help you find lost keys, remotes, eyeglasses
and other easily misplaced items quickly. Simply press one of the color-coded buttons on
the remote and the corresponding receiver will beep loudly for 5 seconds, leading you to
your missing item.
The JTD-KF4F also features an LED flashlight. The ON/OFF switch is located on the right
side of the remote and allows you to turn on and off the LED flashlight easily. This becomes
extremely handy when you need to find something in the dark.
The JTD-KF4F includes a docking base for the transmitter remote to be store while not in
use. The transmitter is removable from the base and can be carried with you to find lost
items.
