UNIDEN Model uh015sx UHF CB Radio
Selcall ID
27
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 the radios in your group use the same Tone Period
setting. Otherwise you will not be able to selectively call one another.
The uh015sx allows you to select which Tone Period is best for you. The three most
commonly used tone settings (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.
