Tx DPL Invert Setting Tx DPL Invert causes Digital Private Line (DPL) signals to be inverted
before they are transmitted from the radio, while operating on the current chan-
nel. Inverted coding allows for more trafÞc/usage on frequencies.
Tx Frequency A designated frequency used when transmitting carrier for the current channel.
Tx Offset The offset that will be added to the VFO Rx Frequency when radio transmits in
VFO mode. Available options are: None (transmits using Rx Frequency), Pos
(transmits using Rx Frequency + Offset Frequency), Neg (transmits using Rx
Frequency - Offset Frequency), User (transmits using the User DeÞned Tx Fre-
quency)
Tx Power The transmit power level while operating on the current channel.
High: Used when a stronger signal is needed to extend transmission distances.
Low: Used when communicating in close proximity, and to keep the radio from
transmitting into other geographical groups operating on the same frequency.
Economy Low: Used when communicating distance is close, e.g., within the
same warehouse, stadium, etc.
Tx TPL Frequency A designated frequency used to transmit Tone Private Line (TPL) encoding,
while operating on the current channel. This frequency can directly correlate to
the Tx TPL Code Þeld; however, non standard code frequencies may also be
selected.
µC Microcontroller.
UHF Ultra High Frequency.
Unmuting A radio unmutes, when it opens its speaker to receive audio.
µP Microprocessor.
Upper Scan
Frequency
The upper limit that VFO will scan.
User DeÞned PL
Frequency
You can customize up to three non standard PL frequencies to provide more
choices for PL.
VCO Voltage-Controlled Oscillator: an oscillator whereby the frequency of oscillation
can be varied by changing a control voltage.
VFO Variable Frequency Operation. The radio user chooses frequencies instead of
preprogrammed channels to operate the radio.
VFO Scan Radio scans the preprogrammed frequency range deÞned by VFO Upper Scan
Frequency and Lower Scan Frequency in the increment deÞned by Frequency
Step Size.
VHF Very High Frequency.
VSWR Voltage Standing Wave Ratio
