* Local/Distance - Radio service software (RSS) easily allows the choice for a Local rather than a Distance setting if you desire the 10dB interference protection that this mode provides. Programmable radio wide or to an option button.
** Repeater/Talkaround - You may utilize a repeater to increase range for your radio's signal or to provide telephone interconnect. Talkaround frequencies do just that - they circumvent the repeater to talk directly to another radio.
*** AdvantagePort Expandability - Allows an authorized dealer to add an Advantage Board to upgrade radio functionality.
