Monitor Frequency/Current
When the type of interface is Tone, Tone with E&M, or DC control, this parameter selects the monitor
frequency/current used when the monitor button is pressed.
Parallel Mute
Enabling this feature causes the unit to mute the speaker, not the handset, when a parallel unit is
transmitting. This is useful when two or more parallel units are co-located and feedback from one unit to
the other is possible. Also when using the mic delay during transmit, the audio is heard on parallel units.
Enabling this feature prevents this.
PTT Function Tone Frequency
Allows use of a predefined function tone when keying the station and can be used when frequency
change control is done with wildcards. This feature is not available with the following type of interfaces:
DC
, E&M, or Local control.
Supervisor OFF Frequency/Supervisor ON Frequency
Available only when the type of interface is Tone or Tone with E&M control, the supervisor frequency
is used to enable tone supervisor control. When a system is properly configured with a supervisor
position and parallel units, the supervisor can initiate the supervisor ON tone burst that disables the
keyboards of all parallel units. This disallows transmissions from those units.
When the supervisor wishes to remove supervisor control, he can press the supervisor button and send
the supervisor OFF tone burst. The parallel units decode this and unlock the keyboard. This feature is
not a replacement for “hard” or control using a relay. It can only be used when there are no parallel units
transmitting. If “hard” supervisor control is needed, use the relay module is required.
N OTE : These parameters are not selectable if the type of interface is Local or E&M. See also: Tone
Supervisor Control and Supervisor Control Via Relay.
Function Tones/Aliases
Each transmit frequency or current may have an alias name with a maximum of eight characters.
 If the interface type is Tone or Tone with E&M control, the number of alias names available is 16.
 If the type of interface is DC control, the number of alias names available is 4.
Frequency Alias Names
This parameter allows you to assign a name to each possible transmit frequency. Alias names may be a
maximum of eight characters long.
Frequencies/Currents
Allows selection of the transmit frequencies or currents for each function tone/current enabled.
Disabling a particular frequency/current causes that frequency/current and all other following to not be
available to the operator for selection during dispatch. Frequencies/currents following the disabled
frequency/current are available as page PTT frequencies in the paging alias screen.
