Rx TPL Frequency A designated frequency used when receiving Tone Private Line (TPL), while
operating on the current channel. This frequency can directly correlate to the
Rx TPL Code Þeld; however, non standard code frequencies may also be se-
lected.
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 chan-
nels can then be scanned for transmission activity - one at a time, when the ra-
dio is in Scan Mode. A Scan List can have a maximum of 16 Scan List
Members. Scan List Member scanning priority is deÞnable. A Scan List can be
assigned to a channel. Three Scan Lists are available. A Scan List can be as-
signed to more than one channel.
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.
Scan Type There are two types of scanning available on the current Conventional Person-
ality: Normal Scan or Priority Scan.
Selective Call Also known as Selcall. This call that allows you to selectively call a radio or
group of radios based on a Call List - Individual, Group, and All ID's.
Serial Number Each radio has its own unique serial number. This information is stored in the
radioÕs codeplug.
Short Press
Function Function that is invoked if the button is pressed and released within one sec-
ond.
Softpot Software Potentiometer: a computer-adjustable electronic attenuator.
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.
Squelch Level The amount of carrier energy required to unmute the radioÕs speaker upon sat-
isfying the selected Carrier Squelch threshold. Low level allows more transmis-
sions with less clarity to unmute the radioÕs speaker. High level increases the
squelch threshold causing a stronger carrier signal to be required before the ra-
dioÕs speaker will unmute. This helps to reduce unwanted noise.
Tone Private Line
(TPL) Transmitted when the receiving radio is to only receive calls from radios with
speciÞc 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 .
TOT Time-Out Timer: a timer that limits the length of a transmission.
TPL Tone Private-line.
Tx DPL Code The Digital Private Line (DPL) code that transmits while operating on the cur-
rent channel.
