4SAFETY INFORMATIONThe operator of any mobile radio should be aware of certain hazardscomEMER to the operation of vehicular radio transmissions. A list ofseveral possible hazards is given:1. Explosive Atmospheres - Just as it is dangerous to fuel a vehiclewith the motor running, similar hazards exist when operating amobile radio. Be sure to turn the radio off while fueling a vehicle.Do not carry containers of fuel in the trunk of a vehicle if the radiois mounted in the trunk2. Interference to Vehicular Electronics Systems - Electronic fuelinjection systems, electronic anti-skid braking systems, electroniccruise control systems, etc., are typical electronic systems that maymalfunction due to the lack of protection from radio frequencyenergy present when transmitting. If the vehicle contains suchequipment, consult the dealer and enlist their aid in determining theexpected performance of electronic circuits when the radio istransmitting.3. Dynamite Blasting Caps - Dynamite blasting caps may be causedto explode by operating a radio within 500 feet of the blasting caps.Always obey the "Turn Off Two-Way Radios" signs posted wheredynamite is being used.When transporting blasting caps in your vehicle:a. Carry the blasting caps in a closed metal box with a softlining.b. Leave the radio OFF whenever the blasting caps arebeing put into or removed from the vehicle.4. Radio Frequency Energy - To prevent burns or related physicalinjury from radio frequency energy, do not operate the transmitterwhen anyone outside of the vehicle is within two feet of the antenna.5. Liquefied Petroleum (LP) Gas Powered Vehicles - Mobile radioinstallations in vehicles powered by liquefied petroleum gas with theLP gas container in the trunk or other sealed-off space within theinterior of the vehicle must conform to the National Fire ProtectionAssociation standard (NFPA) 58 requiring:
5• The space containing the radio equipment shall be isolated by a sealfrom the space containing the LP gas container and its fittings.• Outside filling connections shall be used for the LP gas container.• The LP gas container shall be vented to the outside of the vehicle.SAFE DRIVING RECOMMENDATIONS FORUSERS OF MOBILE RADIOS RECOMMENDEDBY AAA• Read the literature on the safe operation of the radio.• Keep both hands on the steering wheel and the microphone in itshanger whenever the vehicle is in motion.• Place calls only when vehicle is stopped.• When talking from a moving vehicle is unavoidable, drive in theslower lane. Keep conversations brief.• If a conversation requires taking notes or complex thought, stop thevehicle in a safe place and continue the call.• Whenever using a mobile radio exercise caution.OPERATING RULES AND REGULATIONSTwo-way FM radio systems must be operated in accordance with therules and regulations of the local, regional or national governmentIn the United States, the KME radio must be operated in accordancewith the rules and regulations of the Federal CommunicationsCommission (FCC). As an operator of two-way radio equipment, youmust be thoroughly familiar with the rules that apply to your particulartype of radio operation. Following these rules helps eliminate confusion,assures the most efficient use of the existing radio channels, and resultsin a smoothly functioning radio network. When using your two-wayradio, remember these rules:1. It is a violation of FCC rules to interrupt any distress or emergencymessage. As your radio operates in much the same way as atelephone "party line", always listen to make sure that the channel
6is clear before transmitting. Emergency calls have priority over allother messages. If someone is sending an emergency message - suchas reporting a fire or asking for help in an accident - KEEP OFFTHE AIR!2. The use of profane or obscene language is prohibited by Federallaw.3. It is against the law to send false call letters or false distress oremergency messages. The FCC requires that you keep conversationsbrief and confine them to business. To save time, use codedmessages whenever possible.4. Using your radio to send personal messages (except in anemergency) is a violation of FCC rules. You may send only thosemessages that are essential for the operation of your business.5. It is against Federal law to repeat or otherwise make known anythingyou overhear on your radio. Conversations between others sharingyour channel must be regarded as confidential.6. The FCC requires that you identify yourself at certain specific timesby means of your call letters. Refer to the rules that apply to yourparticular type of operation for the proper procedure.7. No changes or adjustments shall be made to the equipment except byan authorized or certified electronic technician.Under U.S. law, operation of an unlicensed radio transmitter withinthe jurisdiction of the United States may be punishable by a fine of upto $10,000, imprisonment for up to two years, or both.OPERATING TIPSThe following conditions tend to reduce the effective range of two-wayradios and should be avoided whenever possible:• Operating the radio in areas of low terrain, or while under powerlines or bridges.• Obstructions such as mountains and buildings.IMPORTANT
7In areas where transmission or reception is poor, some improvementmay be obtained by insuring that the antenna is vertical. Moving a fewyards in another direction or moving to a higher elevation may alsoimprove communication.INTRODUCTIONThis manual describes the operation for the Ericsson KME- Mobileradio.

11DISPLAYKME- DisplaySP1SCANP2CGPGEIGHT CHARACTER ALPHANUMERIC DISPLAYSelective SignalingON/OFFScanChannel Priority 2ChannelScanON/OFF Channel GuardON/OFFPriority 1ChannelFigure 2 - KME- DisplayThe KME- includes an eight character 14-segment display and six statusicons. The eight character first line is used to display the selectedchannel, menu items and miscellaneous operating conditions. When theradio is programmed a personality or computer file is downloaded intothe radio. The personality defines how the radio will operate and is usedto tailor the operation of the radio for each application. Since the KMEradio clearly displays alphanumeric characters, an eight character namecan be created for each of the following items: Systems Individual Calls Channels Group CallsThe KME- radio displays the selected channelby displaying the selected channel name asdefined in the personality. For example, this iswhat will appear in the display if the name forchannel 4 is defined in the personality as“Police 1”.
12STATUS INDICATORSThe status indicators or icons are located at the bottom of the displayand provide an indication of various radio operating characteristics.The S icon is used for channels in the scan list. The Sicon turns on if the selected channel is part of the scanlist. The scan list is a group of channels the radiocontinuously Monitors for activity. This list can bemodified by the radio programmer or by the radio user.The P1 icon is used for priority 1 channels. The P1 iconturns on when the selected channel is defined as thepriority 1 channel or when the radio receives a call onthe priority 1 channel. In scan mode, channels definedas priority channels have precedence over non-prioritychannels. If a priority 1 channel is decoded, the radiowill drop a call while on a non-priority channel or apriority 2 channel and then switch to the priority 1channel to receive the call. This channel will also bescanned more often than non-priority channels and thepriority 2 channel.The SCAN icon indicates the condition of the SCANmode. The SCAN button is used to toggle scan ON andOFF. When scan is ON, the radio Monitors all thechannels in the scan list for any activity. The SCANicon turns on when the scan mode is enabled.The P2 icon represents priority 2 channels. The P2 iconturns on when the selected channel is defined as thepriority 2 channel or when the radio receives a call onthe priority 2 channel. In scan mode, channels definedas priority channels have precedence over non-prioritychannels. If a priority 2 channel is decoded, the radiowill drop a call while on a non-priority channel and thenswitch to the priority 2 channel to receive the call. Thischannel will also be scanned more often than other non-priority channels, but less than the priority 1 channel.
13The CG icon represents decode Channel Guard. Whenthe user selects a channel preprogrammed with decodeChannel Guard, the CG icon turns on. Channelsprogrammed with Channel Guard only allow the user tohear calls carrying the equivalent Channel Guard tonesor digital codes. This reduces the amount of "channelchatter" the user hears.The PG icon represents selective signaling. When theuser selects a channel preprogrammed with Multi-toneor Type 99 tone signaling, the PG icon turns on.Selective signaling is used to initiate individual calls,group calls, all calls, etc. When the radio is in theMonitor mode the PG icon flashes.TX/RX INDICATORThis indicator is located above the EMER button. Thisindicator contains a red LED and green LED. When theradio is transmitting the red LED turns on. When theradio is receiving a call, the green LED turns on.
14ALERT TONESThe KME radio generates a number of unique audible alert tones or“beeps” to indicate various operating conditions. The alert tone featurecan be enabled or disabled through PC Programming. All of the KMEalert tones are described in the following sections:BASIC OPERATIONTURNING THE RADIO ONTypically, mobile radio installations require the vehicle ignition switchto be in the Accessory or Run position before the radio will power ON.In some applications, the radio is wired directly to the battery and theradio will power ON regardless of the setting of the vehicle ignition.Verify with the installer, how the radio has been connected.From the OFF position, rotate the ON/OFF Volumeknob clockwise until the knob clicks. The radioperforms a diagnostic test and then sounds three shorttones to indicate the radio has passed the diagnostic testand is ready for operation. The display comes ON andindicates the currently selected channel.?The KME mobile preserves the following data from theprevious operating state:• Channel Number (unless preprogrammed with a power-up channel)• Scan ON/OFF State• Scan List• Radio Enable/Disable
15SELECTING OR CHANGING CHANNELSRotate the Channel Selector Knob clockwise orcounterclockwise until the desired channel appears inthe display.The Channel Knob is a continuous rotary knob that isused to select the desired channel from apreprogrammed list of channels. Rotate the knobclockwise to increment to the next channel in the list.When the end of the list is reached the radio will wrapto beginning of the list. Rotate the knobcounterclockwise to decrement to the previous channelin the list.CHANGING SYSTEMS1. Press the M button. This will bring up the KMEradio main menu.2.

20SCAN OPERATIONThe KME- mobile radio can be set up to scan (Monitor) up to 16channels on the selected system. The scanned channels may be anyfrequency within the frequency band limits of the radio. If the radiopicks up activity on one of the scanned channels, the radio will switch tothe channel and allow the user to receive the call. When the call is done,the radio automatically switches back to the knob-selected channel.When scan is turned ON, the radio scans all the channels in the scan list.Initially, the scan list is created when the radio is PC Programmed, butthe KME radio allows the user to modify the scan list.The scan list can also include a priority 1 channel and a priority 2channel. In scan mode, channels defined as priority channels haveprecedence over non-priority channels. If a call on a priority 2 channel isreceived, the radio will drop a call while on a non-priority channel andswitch to the priority channel to receive the call. If a call on a priority 1channel is received, the radio will drop a call while on a non-prioritychannel or a priority 2 channel and then switch to the priority 1 channelto receive the call. Priority channels are also scanned more often thannon-priority channels.The following sections describe how to use the scan feature on theKME- mobile radio.SCAN ON/OFF1.

34Emergency TransmissionsThe KME radio can be programmed and installed to send emergencysignals. To initiate an emergency call, the Option Cable (KRD 103133/45) must be installed with a customer supplied emergency button orswitch. See the Installation Manual LZT 123 4452 for more information.Emergency signaling is defined in the personality. The programmablefeatures related to emergency signaling are described below:v The emergency can be programmed to transmit on the selectedchannel, or on a pre-programmed Home/Emergency Channel.v The emergency can be programmed with or without anacknowledgement from the base station. If an acknowledgement isrequired, the radio will display FAIL if the acknowledgement is notreceived.v The KME radio can also be programmed to send a silent emergency.In a silent emergency, the radio transmits the emergency without anyindication of a transmission. The TX indicator does not light and allreceived calls are muted until the user presses the PTT button. Thereceived calls are muted to keep from endangering the user thatdeclared the silent emergency.To Send An EmergencyPress and hold the emergency button for at least 1 second.Base Station CallsIn an Enhanced environment, the radio is capable of receiving severalunique calls from the base station dispatcher. These calls do not requirea response from the user. The following sections describe each type ofcall.Interrogate RadioThe interrogate feature allows the dispatch base station to validate theparticipation of a radio Monitoring the system. The base station sendsout a message to a particular radio that includes the radio ID and theinterrogate message. If the radio receives a call that includes its own IDand the interrogate message, the radio responds by transmitting its ownradio ID back to the base station. The radio receives the call and
35responds (transmits) back to the base station without providing anyindication to the radio user.Disable RadioThe radio disable feature allows the dispatch base station to disable anyradio Monitoring the system. The base station sends out a message to aparticular radio that includes the radio ID and disable message. If theradio receives a call that includes its own ID and the disable message,the radio responds by transmitting its own radio ID back to the basestation. After responding to the base station, the radio enters a disabledor kill mode. In the disable mode, the radio will receive calls, but noaudio is heard at the speaker. The Push-To-Talk button is also disabled.The radio is disabled for all channels in the system. The radio will onlyrespond to an interrogate call or radio enable call.Enable RadioThe radio enable feature allows the dispatch base station to reactivate orenable any radio Monitoring the system that had previously beendisabled. The base station transmits a call to a particular radio thatincludes the radio ID and the enable message. If the radio receives a callthat includes the its own radio ID and the enable message, the radioresponds by transmitting its own radio ID back to the base station. Afterresponding to the base station, the radio exits the disabled or kill mode.Reset RadiosThe reset radio feature allows the base station to reset a particular radioon the system to the selective state. The base station sends out a messageto a particular radio that includes the radio ID and the reset message. Ifthe radio receives a call that includes its own ID and the radio resetmessage, the radio responds by resetting the decoder back to theselective state. The mobile radio does not send an acknowledgementback to the base station.
