Uniden UH-099 owner manual Tone Period Programming

Tone Period

Tone Period is the duration of one tone in a SELCALL ID sequence. The setting of this parameter depends on the type of application. On long distance communications for example, where the signal strength of the transmitted information is greatly reduced and affected by noise, it is advisable to use a longer Tone Period. A long Tone Period gives the decoder more time and information to check and evaluate the code.

However, be sure that all radios in your group use the same tone period setting. Otherwise you will not be able to selectively call one another.

The Sundowner UH-099 allows you to select which tone period is best for you. The four most commonly used tone settings (20, 40, 70, or 100 mSec) are available. With the freedom to change this parameter, you can easily adapt to the existing system in your group without the inconvenience of having the unit serviced by the dealer.
