Select
This function will "Select" the appropriate channel for transmission when a transmit key is
pressed. The received audio from the selected channel will be heard on the "Select"
speaker. All other received audio will be routed to the "Unselect" speaker. All channels
must have one and only one "Select" key assigned.
Answer/Hold
This key requires telephone control. The key is used to answer a telephone call. Once a
call is answered (telephone is off-hook), this key toggles the hold function.
Frequency Select
This key is only applicable with a tone or DC controlled radio with multiple frequency
capability. By selecting this key, the desired frequency command will be sent. The current
or tone will be sent to the radio in order to select the desired frequency.
Please note that "no current" is different from 0.0 ma. Selecting "0.0 ma" will cause zero
milliamperes of DC control current to be sent when this command is executed. Selecting
"No current" will cause the previous control current for that function to be maintained;
that is no current change.
After selecting the receive current/tone, you must also specify a current or tone to activate
the transmitter for the desired frequency.
Frequency Select with Voting
This key is identical to the frequency select function with the added feature of selecting an
auxiliary input. This allows the output of a voter to indicate which frequency was voted.
The red LED will be illuminated for the frequency that voted.
The input must have been previously defined before using this key.
Instant Select
Instant Select differs from the normal Select function in that after the Select is performed,
a DC or Tone control function is sent. This is normally used on a multi-frequency base
station to select a channel at a desired frequency. Several Instant Select keys may be
assigned to a single channel even though only one can be active at a time.
Instant Select with Voting
If you chose instant select with voting, you must also pick the Auxiliary input that will
receive the voter result. This input indicator will be illuminated whenever the voter picks
this particular input. The input must have been previously defined using the System
