not possible to transmit on this group/channel in clear mode. If the radio does not ha v e the correct encry ption k ey loaded, "NO KEY #" will be display ed and the call will not be transmitted. 3. Continue with standard transmission procedures.
LAST SYSTEM/GROUP OR CHANNEL RECALL (SUPER VISOR Y RADIO UNITS ONL Y ) This feature enab les the us er to recall the last se- lected system/group after an ED ACS emergency or home function, a c onv entional emergency or home func- tion or sy stem/group ke y function.
ED A CS TR UNKED MODE OPERA TION Digital trunking provides fast communication access at all times, e ven during busy hours . In this mode the operator selects a communications system and group, and the audio communication or wor king channel (WC) is allocated through digital signalling with the site.
6. GROUP CALL - When the radio receives a group call, it unmutes on the assigned working channel and comes on. Line one shows GR follo wed by the logical ID number (if received) of the unit sending the message, or the assoc iated name if the ID number is found in the individual call list.
3. When the working channel is assigned, and are tur ned on and a shor t beep s ounds indicat- ing that communication can begin. 4. Hold the radio approximately three inches from the mouth and speak in a normal voice into the micro- phone (located between and on the ke ypad).
it will not be pos sible to select a communications c han- nel, or use emergency and special call. When trunking is restored, the radio will automatically be retur ned to nor mal operation. SCA T OPERA TION A SCA T (Single Channel Autonomous T runking) Sys- tem operates with the same set of features as a standard ED ACS system.
Receiving An Emergen cy Call When receiv ing an emergency call from the selected group and system, an aler t beep is heard and comes on. The message *RXEMER* flashes in the dis- play on line two until the emergenc y condition is cleared. F ollow standard emergency procedures.
5. The emergency can be cleared by pressing and holding the CLEAR/MONITOR b utton f ollowed b y pressing the EMERG ENCY button then releasing both buttons . SCANNING TRUNKED S YSTEMS The follo wing f eatures allow interaction with systems other than the selected system to meet specific customer needs.
Priority System Scan The radio ma y also be programmed f or prior ity sys- tem scan. A prior ity system may be assigned among the systems programmed into the radio . Radios programmed in this manner will check f or the priority trunked system’ s control channel at a programmable rate ranging fr om 1 to 16 minutes.
Dele ting Groups From A Scan List 1. With sc an operation tur ned off, select the desired group to delete from the selected s ystem’ s group scan list. 2. Pre ss . tur ns off. Any group that is not in a system’ s group scan list will not s how when it is the selected group .
2. When a group on the scan lis t receives a channel assignment, the radio unmutes on the assigned channel and comes on. Line one shows GR follo wed b y the logical ID number (if received) of the unit sending the message, or the associated name if the ID number is found in the individual call list.
PROGRAMMABLE ENTRIES Individual call ID numbers, telephone numbers and other number sequences for overdialing are stored in the special call lists when programming the radio . The first ten entr y locations of these lists c an be changed by the radio operator .
INDIVIDU AL CALLS Receiving And Respo nding T o An Individ ual Call (T runked Mode Onl y) When the radio re ceives an individual call (a call directed only to the user’ s radio), it unmutes on the assigned working channel and turn s on the indi- cator .
stores the ID’ s of the last 10 c allers in the Calls Received List as s hown. Indiv idual calls are s tored in the top half of the list (1-10), and group c alls are stored in the bottom half of the list (1-10). The most recent call is stored in position 1, the sec ond most recent call is s tored in position 2, etc.
Call Stora ge Lists There are two lists a v ailable f or call storage in the radio , the calls received list (1-10) and the personality list (1-99 as defined b y the user). When the indiv idual call mode is entered b y pressing , the calls rec eiv ed list is av ailable .
When in the pre-stor ed list, pressing toggles the Logical IDentification (LID) on and off. Sending An Ind ividual Call (T runked Mode Only ) The f ollowing procedures describe how to initiate and complete an individual call.
