or the MENU button has been pressed (the MENU button will override the time-out period), the status is

selected and will be transmitted to the site or stored in the radio memory where it can be polled by the site

at a future time. If the site receives the status properly, when transmitted or polled by the site, a high-

pitched tone sounds and the keylight associated with that status will remain lit. If the site does not receive

the status properly, a low-pitched tone sounds and the keylight associated with the status will blink.

If an incorrect status was selected or the incorrect number button was pressed, the status can be changed

during the pre-programmed time-out period by pressing another number button. The status selection can

also be cancelled by pressing the CLR button prior to the time-out period.

To view the currently selected status after it has been transmitted, press the STS button. If the status wa s

not sent successfully to the site, the text associated with the status will flash in the display.

The radio can also be pre-programmed to redesignate the keypad buttons for ST0 thru ST9 to send status

condition. In this configuration the radio status operation will operate as previously described except the

STS button is not required. The keylight associated with ST0 thru ST9 will indicate which status is

selected.

Message operation permits the transmission of a pre-programmed message text to an EDACS site.

To send a message, press the MSG button (keylight comes on) then press one of the number buttons (0-9)

to select the pre-programmed message text. If no message text has been programmed for the selected

number button, the radio will display NO ENTRY and a low-pitched tone sounds. A valid selection will

permit the message text to appear in the display for a pre-programmed time. After the time-out expires or

the MENU button has been pressed (the MENU button will override the time-out period), the message

text is selected and will be transmitted to the site. If the site receives the message properly when

transmitted, a high pitched tone sounds and the MSG keylight remains lit. If the site does not receive the

message properly, a low-pitched tone sounds and the MSG keylight will blink.

If an incorrect message text was selected or the incorrect number button was pressed, the message text

can be changed during the pre-programmed time-out period by pressing another number button. The

message text selection can also be cancelled by pressing the CLR button prior to the time-out period.

To view the currently selected message text after it has been transmitted, press the MSG button and then

the CLR button prior to the ti me-out period. If the message text was not sent succes sfully to the site, the

text associated with the message will flash in the display.

9.16 EDACS CONVENTIONAL P1 SCAN

This feature permits the radio user to scan a pre-programmed conventional system and channel as a

Priority 1 (P1) channel while the radio is selected for EDACS trunked system. If activity is detected on

the conventional P1 channel, the radio will unmute and remain on this conventional channel for the

programmable hang time.

The radio must be pre-programmed to designate a button for scan ON/OFF operation.

Dynamic regroup operation permits multiple talk groups (up to eight) to be added to a radio via the

Communications Systems Director (CSD). The radio must be pre-programmed to respond to regrouping.

Dynamic regrouping will not be activated in a radio until an activation message is sent by the system

manager. Each radio that receives and acknowledges regrouping instructions is successfully regrouped.
