It contains all required service in-formation for the equipment and is current as of this publica-tion date. Changes which may occur after publication arecovered by either Service Bulletins or Manual Revisions,which are issued as required.ORDERING REPLACEMENT PARTSWhen ordering replacement parts or equipment informa-tion, the full part identification number should be included.This applies to all parts : components, kits, and chassis. Ifthe part number is not known, include the chassis or kitnumber of which it is a part and a sufficient description ofthe required component, for proper identification.PERSONAL SAFETYThe following precautions are recommended for personalsafety :DONOT transmit if someone is within two feet (0.6meter) of the antenna.DONOT transmit until all RF connectors are secure andany open connectors are properly terminated. SHUT OFF this equipment when near electrical blastingcaps or while in an explosive atmosphere. All equipment should be properly grounded beforepower-up for safe operation. This equipment should be serviced by only qualifiedtechnicians.PRE-INSTALLATION CONSIDERATIONS1. UNPACKINGUnpack the radio from its shipping container and checkfor accessory items. If any item is missing, please contactKENWOOD immediately.2. LICENSING REQUIREMENTSFederal regulations require a station license for eachradio installation (mobile or base) be obtained by theequipment owner. The licensee is responsible for ensuringtransmitter power, frequency, and deviation are within thelimits permitted by the station license.Transmitter adjustments may be performed only by alicensed technician holding an FCC first, second or generalclass commercial radiotelephone operators license. Thereis no license required to install or operate the radio.3. PRE-INSTALLATION CHECKOUT3-1. IntroductionEach radio is adjusted and tested before shipment.However, it is recommended that receiver and transmitteroperation be checked for proper operation beforeinstallation.3-2. TestingThe radio should be tested complete with all cabling andaccessories as they will be connected in the final installa-tion. Transmitter frequency, deviation, and power outputshould be checked, as should receiver sensitivity, squelchoperation, and audio output. Signaling equipment operationshould be verified.4. PLANNING THE INSTALLATION4-1. GeneralInspect the vehicle and determine how and where theradio antenna and accessories will be mounted.Plan cable runs for protection against pinching or crush-ing wiring, and radio installation to prevent overheating.4-2. AntennaThe favored location for an antenna is in the center of alarge, flat conductive area, usually at the roof center. Thetrunk lid is preferred, bond the trunk lid and vehicle chassisusing ground straps to ensure the lid is at chassis ground.3TK-5710(B)/5710H(B)4-3. RadioThe universal mount bracket allows the radio to bemounted in a variety of ways. Be sure the mounting surfaceis adequate to support the radios weight. Allow sufficientspace around the radio for air cooling. Position the radioclose enough to the vehicle operator to permit easy accessto the controls when driving.4-4. DC Power and wiring1. This radio may be installed in negative ground electricalsystems only. Reverse polarity will cause the cable fuseto blow. Check the vehicle ground polarity beforeinstallation to prevent wasted time and effort.2. Connect the positive power lead directly to the vehiclebattery positive terminal. Connecting the Positive lead toany other positive voltage source in the vehicle is notrecommended.3. Connect the ground lead directly to the battery negativeterminal.4. The cable provided with the radio is sufficient to handlethe maximum radio current demand. If the cable must beextended, be sure the additional wire is sufficient for thecurrent to be carried and length of the added lead.5. INSTALLATION PLANNING CONTROL STATIONS5-1. Antenna systemControl station. The antenna system selection dependson many factors and is beyond the scope of this manual.Your KENWOOD dealer can help you select an antennasystem that will best serve your particular needs.5-2. Radio locationSelect a convenient location for your control station radiowhich is as close as practical to the antenna cable entrypoint. Secondly, use your systems power supply (whichsupplies the voltage and current required for your system).Make sure sufficient air can flow around the radio andpower supply to allow adequate cooling.SERVICEThis radio is designed for easy servicing. Refer to theschematic diagrams, printed circuit board views, andalignment procedures contained in this manual.NOTEYou must use KPG-95D version 2.00 or later for thistransceiver. KPG-95D version 1.XX does not workproperly.GENERAL4TK-5710(B)/5710H(B)SYSTEM SET-UPBefore Reading About System Set-upThe TK-5710(B)/5710H(B) is a transceiver main unit(without a panel or speaker) that you complete by addingoptions.The options are classified into three types according tooperation and function.Merchandise receivedLicense and frequency allocated by FCCChoose the type of transceiverTK-5710(B) or TK-5710H(B) is complete by combiningoptions with only the transceiver body (without panel)Are you using the remote kit?KCH-14 (Basic model)Front panel kitKCH-15 (Full-featuredmodel) Front panel kitSupplied accessory keytopsAre you using one radio with two controllers?Are you using one radiowith one controller?Are you using the printed keytops?KRK-5Single control head remote kitKRK-6DHDual control head remote kitKCH-14 KCH-15KCH-14+KCH-14KCH-14+KCH-15KCH-15+KCH-15oror orKCT-22M/M2/M3Control cableYESYESNONOSee page 11See page 11YESFrequency range136174MHzYESSee pages 13 and 14Transceiver programmingKCT-23 DC cableDelivery(Option)(Option) (Option)(Option)(Option)Desk top microphone KMC-9BAre you using the voice guide If one of keys 0 to 9 is pressed while “CLONE LOCK“ isdisplayed, the pressed number is displayed on the LCD.Each press of the key shifts the display in order to the left.If you press the # key, the least digit of the password isdeleted.When you enter the password and press the key,“CLONE MODE” is displayed if the entered password iscorrect. If the password is incorrect, “CLONE LOCK” isredisplayed. How to enter the read authorization password usingthe Selector knob;If the Selector knob is rotated while “CLONE LOCK“ isdisplayed, the number (0 to 9) flashes on the LCD. Whenyou press the GRP key, the currently selected numberis determined. If you press the PF3 key, the least digit ofthe password is deleted. If you press the PF2 key afterentering the password in this procedure, “CLONEMODE” is displayed if the entered password is correct. Ifthe password is incorrect, “CLONE LOCK” is redisplayed.4. Power ON the slave transceiver.5. Connect the cloning cable (part No. E30-3370-05) to themicrophone jacks on the master and slave.6. Press the PF2 key on the master while the master dis-plays “CLONE MODE”. The data of the master is sent tothe slave. While the slave is receiving the data, “PRO-GRAM” is displayed. When cloning of data is completed,the master displays “END”, and the slave automaticallyoperates in the User mode. The slave can then be oper-ated by the same program as the master.7. The other slave can be continuously cloned. When thePF2 key on the master is pressed while the master dis-plays “END”, the master displays “CLONE MODE”.Carry out the operation in step 4 to 6.Notes: Cannot be cloned if the overwrite password is pro-grammed to the slave. “Model Name and Market Code“, “Head Configuration“ and“Head Type“ must be same to clone the transceiver. How-ever, it may be unable to clone the transceiver dependingon the enhanced features settings.(Refer to the FPU for the enhanced features details.)Fig. 2PF5+Power ONIs Read password set?“CLONE LOCK” is displayed.YesYesPF2NoNoEnter the password and then press the PF2 key or * keyon the microphone.Start the clone function“CLONE MODE” is displayed.Is passwordcorrect?Cloning cable(Part No. E30-3370-05)Flow Chart (Master transceiver)8TK-5710(B)/5710H(B)No. Setup item Display Remarks1 Select Zone/Channel - Zone : 150, Channel : 12502 RX Frequency 1 .
