Section 8Determining Available Options
This manual describes the operation of all features that are currently available for the 51xx
ES radio. However, many of these features are optional and therefore may not be available
in your radio. For example, Project 25 trunked operation is optional and may not be
available. Model III radios have the DTMF keypad, but the Model II radios do not have
this feature.
Availability of optional features is controlled by factory programming of the control logic.
Only those features that are specifically ordered and enabled in a particular radio are
available for use and can be programmed. The features controlled by factory programming
are as follows:
