8. TX Frequency (MHz)
Sets a frequency (in MHz) on which a signal is transmitted for the current channel.
9. Default Frequency (MHz)
Selects the Reference Frequency used when transmitting on the current channel. The reference
frequency can be shifted to allow the radio to operate on channel frequencies that would otherwise
be blocked by internally generated spurious signals. Internally generated spurious signals would
appear as silent carriers on certain channel frequencies. Shifting the reference frequency allows
these permanent signal carrier to be shifted to unused frequencies so that the desired channel
frequencies can still be used. The options are Default, 5.6MHz or 8.4MHz
10. Emergency System
Associates any available digital emergency system to this channel for use during an emergency.
Selecting the None option disables the user from transmitting an emergency call from this channel.
Notes:
Configure the Digital Emergency system under the signaling systems folder before selecting it or the
default will be used.
The RX Only feature must be disabled.
11. Power Level
Sets the radio’s transmission power level for this channel. This feature can be toggled between high or
low, via a short or long programmable button press (High/Low Power) or Power (Utilities Menu)
feature.
Notes
High Used when a stronger signal is needed to extend transmission distances.
Low Used when communicating in close proximity, and to prevent transmissions into other
geographical groups.
For UHF Portable, Low Power is equivalent to 1W and High Power is equivalent to 4W. For Mobile and
Repeater, the High and Low values are configurable through the TX High Power (W) and TX Low
Power (W) features under General Settings.
12. TOT (sec)
The Time-Out Timer (TOT) is the duration that the radio can continuously transmit before
transmission is automatically terminated. This feature is used to ensure the channel is not
monopolized by any one radio. The user may set smaller time-outs for busier channels.
