LBI-38836B INTRODUCTION The Ericsson GE Dual Format PCS Personal radio is a rugged, lightweight unit which is housed in a molded Lexan Front assembly and an Aluminum Rear casting. The new PCS radio provides reliable service in the 800 MHz band and contains new DUAL FORMAT technology that enables the radio to operate within a GE-MARC trunked system and an EDACS trunked system.

LBI-38836B TRUNKED FEATURES (EDACS/GE-MARC) EDACS (Only) FEATURES Preprogrammed DIG/DTMF Numbers Group Scan During the PC programming of the radio, the special call list may be programmed with up to 96 numbers for EDACS and 96 numbers for GE-MARC, depending upon available personality space. Using the SPC key, the numbers can be recalled to initiate the special call. The radio monitors the control channel and responds to all group channel assignments associated with the "scan" list.
LBI-38836B return to the normal system/group display. Wide Area Scan (Optional) When the radio unit loses the control channel of the current system, the radio automatically begins searching for a new control channel. The intelligent search algorithm uses a preprogrammed map of adjacent systems to ensure minimum transition time. Conventional - Pressing SHIFT/CLR button twice ("double click") will enable MONITORING the channel for activity by unsquelching the receiver.
LBI-38836B LOCK The LOCK key in combination with the SHIFT/CLR key is used to lock the keypad. All buttons and keys will be locked except the VOLUME, PTT, H OM E/ E , SHIFT / CLR and the LOCK (shifted 0). This key is available on System models only. RCL The RECALL key (shifted #) can be used to recall manually entered individual and interconnect calls in the EDACS and GE-MARC systems. This is available on System model radios and is active with trunked systems only.
LBI-38836B S The "S" Flag is used to indicate two conditions. The "S" flag is used in conjunction with the "PC" flag to indicate the radio is in the Special Call mode. The "S" flag is also used to indicate when a trunked group is scan enabled. PC The "PC" flag is illuminated with the "S" flag to indicate the radio is in the Special Call mode. When the "PC" flag is illuminated without the "S" flag, the radio is in the Program mode. 1 The "1" flag is used only for radio logical ID display.
LBI-38836B CHARGING THE BATTERY PACKS locations in the presence of Groups A, B, C and D atmospheres. New batteries or batteries that have been stored for a long period of time, should be fully charged before placing into service. When the battery pack requires charging the "BAT" indicator in the LCD will turn on and the radio will sound a high pitch tone every 130 seconds. Hazardous locations are definedin the National Electrical Code.
LBI-38836B EDACS SYSTEM DESCRIPTION The Dual Format PCS 800 MHz digital trunked portable radio provides fast access to available RF channels and a degree of privacy due to selective signaling. This also eliminates annoyance of other system user’s conversations while ensuring that intended calls are not missed. The system uses 9600 baud high speed digital signaling to identify individual units, user groups, fleets and agencies.

LBI-38836B ORIGINATING A CALL When originating a call, the portable identifies an idle repeater channel and interrogates it with a single burst of "busy" tone, the repeater keys its transmitter and sends a burst of "acquisition" tone back to the portable unit. When the interrogating portable detects the acquisition tone, it then transmits its collect and group tones, which the repeater regenerates for all idle portable units in the system.
LBI-38836B If a channel with no busy tone is found, the portable transmits a burst of busy tone to acquire the repeater. The repeater then responds with a burst of acquisition tone. Upon receipt of the acquisition tone, the portable proceeds to transmit the group tones (either two or four tones). If a four tone sequence is sent, the portable must detect all four tones and busy tone before entering the Ready Mode.
