Description of Key Functions and Parameters
Volume Reset
This key will cause the received audio level of the selected channel to be set to its default
level, usually 51%. This function only has meaning if the Console Volume Card option is
installed.
Group Select
The group select key allows a set of preselected radio channels to be selected with a single
key. Mark check boxes to add or delete a channel from this group key. Several group keys
may be defined on a single position. A channel may be a member of several different
groups. If a channel card is not installed in the system, its channels will not show in the
table.
If the channel chosen is tone or DC and is defined as a multi-frequency channel, you will
be asked to select the desired function (tone or I) to be used when this key is activated.
Group Instant Tx
The group instant transmit key will cause all members of the group to be keyed with a
single key. Mark check boxes to select channels for this key. A channel may be a member
of several different groups. If a channel card is not installed in the system, its channels will
not show in the table.
If the channel chosen is tone or DC and is defined as a multi-frequency channel, you will
be asked to select the desired function (tone or I) to be used when this key is activated.
Patch Keys
The system patch keys are only valid if an optional Patch Card is installed. A normal patch
key must be assigned to each channel to be patched. Pressing the desired Patch A-H key
and the channel patch keys will cause those channels to be patched.
Up to two Patch Cards may be installed in a system giving the capability for multiple
simultaneous patches. Never use the patch A-H keys if a patch card is not installed.
If the Patch keys (A-H) are defined, the normal patch function will not operate. The Patch
card must be installed if these keys are defined.
Priority Marker
To cause the priority marker to be sent when this key is pressed, click the channel number
for a specific channel or click “Select” or “Transfer”. Clicking “Select” will cause the
marker to be sent on the “Selected” channel. Clicking “T” will cause the marker to be sent
to channel of the next “select” key pressed.
Console I'com Transmit
This key will cause the microphone audio to be transmitted to the console(s) which have
been “called” by the console I'com call key.
