Scan List	The Scan List determines which channels the radio scans, when operating in
	the Scan Mode, on the current channel.
Scan List Member	The Scan List allows you to select the grouping of channels that make up the
	current Scan List Member channels. This grouping of Scan List Member channels
	can then be scanned for transmission activity - one at a time, when the radio is in
	Scan Mode. A Scan List can have a maximum of 16 Scan List
	Members. Scan List Member scanning priority is definable.
Scan Mode	When the radio is in one of the two Scan States: Active Scan and Landed Scan.
	This mode is initiated when the programmable SCAN button is pressed.
Serial Number	Each radio has its own unique serial number. This information is stored in the
	radio‟s codeplug.
Software	Computer programs, procedures, rules, documentation, and data pertaining to
	the operation of a system.
Squelch	Muting of audio circuits when received signal levels fall below a pre-determined
	value.
Tone Private Line	Transmitted when the receiving radio is to only receive calls from radios with
(TPL)	specific TPL codes, this creates communications groups while operating in
	Conventional Dispatch mode. TPL allows for more use and privacy on a fre-
	quency. TPL is transmitted at a sub-audible (not able to be heard) frequency.
	Also known as CTCSS.
Tx Frequency	A designated frequency used when transmitting carrier for the current channel.
µC	Microcontroller.
UHF	Ultra High Frequency.
