5n Setup Procedure1) Turn ON the transceiver being used for TRP.2) Set up its DTSS code and CTCSS frequencyon the 440 MHz band, its operation frequencyon the 144 MHz band, and its operationfrequency on the 440 MHz band. (Thesesettings must be the same as those in the CMDmode).3) Turn OFF the transceiver’s power.4) Press and hold the PTT and CALL buttons,and then turn ON the transceiver's power. Thefollowing display appears when TRP mode isset up successfully.Note: Using a high CTCSS frequency may cause an audibletone to be output from the speaker of the HF transceiver. If thishappens, select a lower CTCSS frequency which does not causethe problem.n Setup Cancellation1) Turn OFF the transceiver’s power.2) Push and hold the PTT and CALL buttons,then turn ON the transceiver’s power.Cancellation is successful when “Sky” and“Trp” no longer appear on the screen.TRP mode provides the specific condition forproviding transfer of the CMD and the signals ofthe HF transceiver. The lamp and power change-over keys can still function while in TRP mode,however, you must return to the conventionalmode of operation before you can reset thefrequency.Set the reception volume control for the 440 MHzband at approximately center.Note: In TRP mode, the power save and APO functions areautomatically turned OFF. Therefore, we suggest you use anexternal power source. When you use the same power supplyas the HF transceiver, you are advised to take care of the HF/RFfeedback through the power supply line. In this case, thesupplied voltage of the TRP is the same as the HF transceiver,so you should be careful to avoid overheating, or othermalfunctions, of the TRP.RS-232C SETUP4,800 bps, 8 data bits, and 2 stop bits are used for setup. It is important that the RS-232C communicationspeed is set up correctly. If the set up is not correct,the HF transceiver will not operate properly.REFERENCE: MENU numbers of HFtransceivers.• TS-570D(G)/S(G): No. 35• TS-870S: No. 56HF TRANSCEIVER SETUPNote: Only the TS-570D(G)/S(G) and TS-870S models can be usedwith this system. Other KENWOOD products will not operate.Please refer to the appropriate instruction manual of the HF unit foroperation of the HF transceiver.Set up the frequency and mode for the operation ofVFO and M. CH. (When an external speaker isconnected to the line from the I/O UNIT, voicesignals cannot be heard. Keeping this in mind, whenyou listen to and confirm a voice signal, you areadvised to either disconnect the line, or use a headset). Set the functions of the HF transceiver whichthe CMD cannot control, beforehand.HF TRANSCEIVER:• Set the AF volume control to the 9:00 to 10:00position.• Set the MIC gain to approximately the center.• Set the squelch control to the fully openedposition.COMMON ITEMS FORTRANSMISSION/RECEPTIONn Confirmation of Preparation• Has the set up of the COMMANDER (CMD)been completed? (See page 3).• Has the set up of the TRANSPORTER (TRP)been completed? (See page 5).• Do the operation frequencies, the DTSS code,and the CTCSS frequency of the CMD and theTRP match?• Has the set up of the HF transceiver beencompleted? (See page 5).n System Initial Set Up1) Turn ON the power supplies of the CMD, theTRP, and the HF transceiver (in any order).2) Push the HF PWR ON key on the CMD (key1). “CTRL” is displayed on the screen of theHF transceiver. If “CTRL” is not displayed,check the Confirmation of Preparation again.3) To turn OFF the HF transceiver’s power, pressthe HF PWR OFF key on the CMD (key 4).After the power is turned OFF, no functionother than HF PWR ON can be performed.Note: Turning OFF the power supply of the equipment duringKSS operation will stop the operation.
