For more information, see the documentation foryour antenna.Installing the TransceiverSee the figure on the below.Screw-fixedbaseMagnet baseCar bodyWasher (M5)Tapping screw (M5 x 20 mm)Mounting bracket<For making 4+/-0.2 mm ø hole in glove box bottom>CAUTION: After installing your antenna, ensure that you have the best possible SWR reading.High RF environments can cause severe damage to your unit. Ensure that you are notin a high RF environment when operating the transceiver.
83. Initial InstallationExternal power supply control & power lamp functionsBe sure the vehicle has a negative-ground, 12VDC electric system before installation. Connect theprovided DC cable directly to the battery as shown below to minimize any possible ignition noise.Be sure the vehicle has a large capacity battery as the use of the transceiver may overload theelectric system of the vehicle.If the ignition-key on/off feature is desired (optional feature), use the optional EDC-37 (For directconnection to the circuit on the vehicle) or EDC-43 (for a Cigar-Plug connection. EDC-36 is alsocompatible) cable. Connect one of the cables between the ACC terminal or a Cigar-Plug that oper-ates with the vehicle ignition or ACC switch on the vehicle and EXT POWER jack on the rear sideof the unit. (Note: In many cars, the cigar-lighter plug is always powered. If this is the case, youcannot use it for the ignition key on/off function.) If this option is selected, the unit can be turnedon/off either manually or automatically in accordance with the ignition key position:1. When the ignition key is turned to ACC or ON (Start) position with the radio turnedoff, the power switch illuminates. The illumination will be turned off when the igni-tion key is turned to the off position. To turn on the unit, press the power switchmanually while it is illuminated (while ignition key is at ACC or ON position).2. When the ignition key is turned to ACC or ON position with the radio's power switchon, the unit turns on automatically and the power switch will be lit. Turn the ignitionkey to OFF position or manually turn the power switch off to shut down the radio.The power consumption when using the additional cable is 5mA.For operation without this option, use the power switch to turn the unit on/off.Power supply voltage display functionAfter connecting the transceiver to the power supply, the supply voltage can be confirmed bypressing the SQL key together with the FUNC key. The supply voltage to the transceiver is thenseen on the display.The transceiver will return to its normal operation when the power is switched OFF.The display immediately changes as the voltage supply changes.It also displays voltage during transmission.IMPORTANT:The range of the displayed voltage is only from 7V - 16VDC. Because the displayed valueis estimated, please use a voltmeter when a more precise reading is desired.DC cableBatteryCigar-Plug connectionACC terminalExt. Power jack

Basic OperationsTurning the unit on and offPress the power switch or turn the ignition key to ACC or ONposition according to the option selected during installation.Press the power switch again or turn the ignition key to OFFposition to turn off.Audio Volume level settingRotate the VOL knob clockwise to increase the audio level,counterclockwise to decrease. Set it at the desired level.Squelch level settingA squelch eliminates white-noise (the background noise whena signal is not received).Higher level settings will keep the squelch “closed” moretightly for quieter monitoring, but weak signals will not beheard. Lower settings allow weaker signals to “open” thesquelch but noise may also cause it to open.1. Press SQL key. SQL icon appears on the dis-play and the squelch level will be shown at theposition where the memory number is dis-played. 21 levels, between 0 and 20, are avail-able. “0” is the lowest setting.2. By rotating the main dial or by using the UP/DOWN keys on the microphone, adjust thesquelch to the desired level. To return to nor-mal use, press PTT or any key on the frontpanel; or if there are no operations within 5seconds, the unit will store the setting and willreturn to its original status.The new squelch level will be stored in the CPU until anotheradjustment is done.Squelch levelPWR keyVOL knobMinimumvolume Maximumvolume
145. Basic OperationVFO modeVFO tuning is set as a default mode at the factory. VFO (vari-able frequency oscillator) allows you to change the frequencyin accordance with the selected channel step as you rotate themain dial or by using the UP/DOWN keys on the microphone.VFO mode is also used to program the data to be stored in thememory channels or to change the parameter settings of thetransceiver.1. Identify the current mode by checking the dis-play. If “M” or “C” icon is NOT displayed onit, the unit is already in the VFO mode.2. Otherwise press “V/M” keys until those iconsare gone.[Change frequency by the channel step]Rotate the main dial clockwise to increase the frequency, coun-terclockwise to decrease. The UP/DOWN keys on the micro-phone act in the same way. [Change frequency by 1 MHz step]This will enable a quick change of frequency in 1 MHz steps:1. Press MHz key. The digits after 100 kHz willdisappear from the display.2. Follow the same sequence as above to changethe value.VFO modeDialFrequencydecrease Frequencyincrease
155. Basic OperationREPEATER (DUPLEX) OperationShift Direction and Offset frequency settingConventional repeaters are operated in the DUPLEX mode.It receives an incoming signal (UP-LINK) on one frequencyand re-transmits on another (DOWN-LINK). The differencebetween these two frequencies is called the offset frequency.If the UP-LINK frequency is higher than the DOWN-LINKfrequency, the direction is positive, and if it is lower, the shiftdirection is negative. The offset is variable between 0 to 99.995MHz on this unit.Press the F key. While the F icon stays on the display, pressMHz key. The display shows the current status of shift direc-tion and offset frequency. The default value is 0.60 MHz (600kHz) in the negative direction. Press MHz key until the de-sired offset direction is set. If SIMPLEX mode (without chang-ing transmit and receive frequency) is desired, select the po-sition where both - and + icons disappeared._0.600 +0.600Shift releaseat-600 kHzChanging the channel step1. Be sure the unit is in VFO mode. Refer to page21 to enter into the SET mode.2. Select the channel step parameter setting usingthe tuning knob. The current channel step willbe displayed as below.3. Press PTT or any one of the keys except SQLon the front panel to enter the desired step intothe transceiver’s memory. The display will thenreturn to the original status.Please note that settings below 10 kHz may be automaticallycorrected according to the selected step.Display for channel stepSTP-5(5 kHz)STP-50(50 kHz) STP-30(30 kHz) STP-25(25 kHz) STP-20(20 kHz)STP-83(8.33 kHz) STP-10(10 kHz) STP-125(12.5 kHz) STP-15(15 kHz)1. Rotate the dial or use UP/DOWN keys on the microphone to change the shift fre-quency. It changes in accordance with the channel step setting.2. In this mode, if the F key is pressed again, the offset frequency can be changed in1 MHz steps for faster setting.3. Press PTT or any key except F or MHz on the front panel to return to the originalstatus.
165. Basic OperationCTCSS / DCS settingMany repeaters require a CTCSS tone or a DCS code encode setting as a “key” to access thesystem, so-called “selective-calling”. Sometimes, CTCSS or DCS decode features are used on theoutput of a repeater so they can be used as a squelch. In this mode, regardless of the main squelchstatus, the audio can be heard ONLY when the matching tone/code signal is received. The combi-nation of CTCSS squelch and DCS function is not available; only one or the other may be used fora given memory channel.1. Press TS/DCS key. The current setting will bedisplayed with T/SQ/DCS icons and relativefrequency/code. Press the same key to selectT/SQ/DCS setting.2. The numbers (such as 88.5) represent the CTCSS frequency in Hz. When it is dis-played with the T icon only, the unit transmits the sub-audible tone while the PTT ispressed (encode) and the repeater access is enabled (assuming the repeater is using88.5).3. Press the same key again so that the SQ icon shows up on the display. This is theCTCSS decode frequency. This enables CTCSS squelch (or Tone Squelch, TSQ).4. Press it again so that the 3-digit number and DCS icon is displayed. This is the DCScode, and it enables DCS encoding and decoding.T88.5 T/SQ88.5DCS023The original statusFor 2 - 4, rotate the main dial or press the UP/DOWN keys to change tone or code. Press any key(Except TS/DCS, UP/DOWN keys) to enter the setting and return to original status. The T/SQ/DCS icon will remain on the display to show the current status. To exit, simply use the TS/DCS keyand press it until the relative status icon T/TQ/DCS disappears.The CTCSS encoding and decoding frequencies may be set differently. The encode setting fre-quency automatically relates to the decode setting, but decode setting does not affect encode. Thestandard set of 39 different CTCSS tones are available as shown on the chart below. DCS encode/decode cannot be separated and are selectable from 104 codes as shown below.NOTE: Depending on the deviation level of the incoming DCS coded-signal, your radio may not open the DCSsquelch. If this occurs, return to DCS setting mode and press the CALL key. A decimal point appears onthe 10 MHz order; then set the desired code. This setting can also be stored in a memory channel.023 025 026 031 032 036 043 047 051 053 054065 071 072 073 074 114 115 116 122 125 131132 134 143 145 152 155 156 162 165 172 174205 212 223 225 226 243 244 245 246 251 252255 261 263 265 266 271 274 306 311 315 325331 332 343 346 351 356 364 365 371 411 412413 423 431 432 445 446 452 454 455 462 464465 466 503 506 516 523 526 532 546 565 606612 624 627 631 632 654 662 664 703 712 723731 732 734 743 754DCS Codes67.0 69.3 71.9 74.4 77.0 79.782.5 85.4 88.5 91.5 94.8 97.4100.0 103.5 107.2 110.9 114.8 118.8123.0 127.3 131.8 136.5 141.3 146.2151.4 156.7 162.2 167.9 173.8 179.9186.2 192.8 203.5 210.7 218.1 225.7233.6 241.8 250.3CTCSS Tone Frequency(Hz)
175. Basic OperationMemory ModeThe memory mode on this transceiver provides up to 100 channels (0-99), 1 call (quick recall ch)and a pair of program-scan “edge memory” channels for quick, easy access to the preprogrammedfrequencies with different parameter settings.Memory modeMemory channelduring the unregistered channel1. Press V/M key. M icon appears on the displayto indicate that the unit is in the memory mode.Repeat to switch the mode between VFO andmemory.2. In memory mode, rotate the main dial or pressUP/DOWN keys to change the memory chan-nel number.3. To change the number by units of 10, pressFUNC and rotate the main dial or press UP/DOWN keys while F icon is on the display. [Memory programming]1. Return to VFO mode by pressing V/M key. Re-ferring to the list below for the programmableparameters, program in the VFO mode to thedesired frequency and settings to be stored laterin the memory.2. When all the settings are complete, press FUNCkey. The F, and M icons appear and a memorychannel number will be indicated on thedisplay.3. Rotate the main dial or press the UP/DOWNkeys to select the desired memory channel num-ber into which the current VFO settings will becopied. An empty channel is shown with a flash-ing M icon. It may be a good practice to “allo-cate” memory channels in order, such as 0-9for local repeaters, 10-19 local simplex, 20-49repeaters within the area, 50-79 for repeater re-serve, 80-98 simplex reserve. It makes refer-ences easier for the operation and future modi-fications of the memory channels.
185. Basic Operation[Programmable data in the memory channel]Some features will be explained later, so please read this instruction manual thoroughly prior toprogramming memories.Memory channels including 0 - 99 and CALL can store following:• Frequency• Shift frequency• Shift direction• CTCSS tone both encode and decode• Tone Squelch setting• DCS code both encode and decode• DCS squelch setting• Scan skip channel• Busy Channel Lock Out setting• Priority monitoring frequency (PC programming required)• Normal/Narrow FM width• AM air-band receive (available on DR-135T / 235T only)NOTE: Only the frequency can be stored in PH and PL channels to determine the edges of the programscan range.4. While F icon is on the display, press MW key.The VFO settings are copied to the memorychannel and a beep will sound. The memorychannel can be over-written if a previously pro-grammed channel is selected (the memorychannels shown with a stable M icon).5. To program the CALL channel (quick recall)select the channel shown with CH-C on the dis-play. Save Ch99 to store the setting used forthe Alarm operation, which will be explainedlater. Use PL and PH for Program scan setting,which will be explained in the advanced op-erations chapter.6. To delete a programmed channel, select it inmemory mode, press FUNC key then press theMW key while F icon is on. The memory is de-leted and a beep sounds. The M icon starts flash-ing showing that this channel is now empty.7. To undo delete, repeat 6. However, the Undofunction becomes impossible once the channelor the mode is changed.
195. Basic OperationCALL modeThis is a memory mode that allows the transceiver to quickly recall the assigned memory channelby simply pressing the CALL key, regardless of the current status of the unit.1. Press CALL key. The C icon appears on thedisplay and the transceiver enters the CALLmode. In this mode, the main dial or the UP/DOWN keys cannot change the frequency ormemory channels.2. Press CALL key again or press V/M key to exitCALL mode.3. No scan functions are available in CALL mode.To store a desired setting in the CALL channel, follow the memory mode programming instruc-tions and assign your selected settings to memory channel C. The call channel can be modified butcannot be eliminated or hidden.To receive signals• Be sure to have the unit connected to the appropriate antenna, powered on, set the audio volume andsquelch level properly.• Select the desired receiving frequency or browse frequencies to listen to ongoing communications. TheS-meter shows relative signal strength between BUSY and FULL when the transceiver detects an incomingsignal.• If the S-meter indicates an incoming signal but nothing is heard from a speaker, check audio level, squelchlevel, and CTCSS/DCS decoding status, which are explained elsewhere in this manual.• A Monitor function is available to receive weaker signals. Press and hold SQL key for more than 1 second.Regardless of the level setting of the squelch, it will be opened and the BUSY icon turns on the display.Press any key on the front panel to exit.
205. Basic OperationTo transmit1. Select the desired frequency. Be sure that youare authorized to operate on the selected fre-quency. Check the system and monitor the fre-quency to make sure that you are not going todisturb any ongoing communications.2. Select the output power. Press FUNC key andthen press CALL key while F icon is on thedisplay. As the CALL key is pressed, the out-put power changes among 3 levels. The Lo iconstands for LOW power setting, Mi for ME-DIUM power. When the transceiver is set atHIGH power, no icon will appear. The outputpower level cannot be changed during trans-mission.3. Default setting is High power. Press the PTTkey on the microphone to transmit, release it toreceive. During transmission, the relative poweroutput is shown on the RF meter as:LOW power = 2 segmentsMID power = 3 segmentsHIGH power = 5 segments.3. If operating from a vehicle, do not transmit forextended periods without running the engine,to avoid battery drainage. Check the batteryvoltage often. The lights, windshield wipers,stereo system, air-conditioner, defogger andother accessories drain the battery’s power con-siderably. When those accessories are turnedon, reduce the output power or turn off one ormore accessories to avoid the battery becom-ing overloaded. Watch the road when driving.Check local regulations that may pertain to theuse of a transceiver when driving.LOW powerMID powerHIGH power

45AppendixTNC Commands ListThe commands supported by the built-in TNC are list below. You must enter a space between acommand name (or short-form) and a parameter, or between two parameters; ex.AU OFF.Command form Default Parameters DescriptionName ShortAUTOLF AU ON ON/OFF When ON, sends a line feed (LF) to the PC after eachcarriage return (CR).BEACON B EVERY 0 EVERY/ If set to EVERY, sends a beacon packet at intervals of theAFTER n specified period (n). If set to AFTER, sends a beacon packet( n=0 - 250 ) only once after the specified period (n). The unit of n is 10seconds.BTEXT BT - 0 - 159 Specifies the content of the data portion of a beaconcharacters packet.CALIBRAT CAL - - Sends a space/mark square wave (50/50 ratio). EnterQ to exit Calibrate mode and restore the Command mode.CHCAK CH 30 0 - 250 Specifies the interval from signal drop-out until executionof disconnection. The unit of the parameter is 10 seconds.CONNECT C - Call1 (VIA Sends a connect request. Call 1 is the call sign of the stationcall1, call3, to be connected to. Calls 2 to call 9 are call signs of stations....call9) to be digipeated through.CONVERSECONV - - Causes the TNC to enter Converse mode. Press [Ctrl]+[C]or K to restore the Command mode.CPACTIME CP OFF ON/OFF When ON and in Converse mode, sends a packet at inter-vals of the period determine by PACTIMECR CR ON ON/OFF When ON, appends a carriage return (CR) to all packets tobe sent.DISCONNE D - - Sends a disconnect request.DISPLAY DISP - -Causes the TNC to display the current status of all the com-mands. You can also specify a class identifier A, C, H, I, L,M, or T to display the status of only the desired commandclass. Enter a space between the command name and a classidentifier; ex. DISPLAY H.A (ASYNC): RS-232C port parameters.C (CHAR) : Special TNC characters.H (HEALTH): Counter parameters.I (ID): ID parameters.L (LINK): TNC-to -TNC link status.M (MONITOR): Monitor parameters.T (TIMING): Timing parameters.DWAIT DW 30 30 Specifies the interval from no carrier detection until execu-tion of transmission. The unit of the parameter is 10 milli-seconds.ECHO E ON ON/OFF When ON, causes the TNC to echo received characters tothe computer.
46AppendixCommand form Default Parameters DescriptionName ShortFIRMRNR FIR OFF ON/OFF The other station sends a notice (packet) to you if it is notready to receive data. When ON, receiving such a noticecauses the TNC to suspend transmission until it receives a“ready” notice.FLOW F ON ON/OFFWhen ON, starting key entry causes the computer to stopdisplaying received packets.FRACK FR 3 0 - 250 Specifies the interval from one transmission until retryof transmission. The unit of the parameter is 1 second.GBAUD GB 4800 4800/9600 Selects 4800 or 9600 bps as the transfer rate betweenthe TNC and the GPS receiver.GPSSEND GPSS - 0 - 159 Specifies the content of the data to be output to the GPScharacters receiver; this data is used to pro gram the default settings onthe receiver. The output data is not stored in memory.GPSTEXT GPST $PNTS 0 - 6 Specifies the type of a message to be determined bycharacters LTEXT.HBAUD HB 1200 1200/9600 Selects 1200 or 9600 bps as the transfer rate betweenpacket stations.LOCATIONLOC EVERY 0 EVERY/ If set to EVERY, sends GPS data at intervals of the speci-AFTER n fied period (n). If set to AFTER, sends GPS data only once( n = 0 - 250 ) after the specified period (n). The unit of n is 10 seconds. LPATH LPA GPS Call1 ( VIA Specifies calls signs to send GPS data. Call 1 is the call signcall2, call3, ... of the destination. Call2 to call9 are call signs of stations tocall9 ) be digipeated through.LTEXT LT - 0 - 159 Specifies the content of a message to be included in GPScharacters data.LTMON LTM 0 0 - 250 Specifies the interval for displaying a message determinedby LTEXT on the screen; a message appears like a receivedbeacon packet. The unit of the parameter is 1 second.MCOM MCOM OFF ON/OFF When ON, causes the TNC to also monitor control packets.When OFF, causes it to monitor only information packets.MCON MC OFF ON/OFF When ON, causes the TNC to monitor other stationswhile in connection with the target station.MONITOR M ON ON/OFF When ON, causes the TNC to monitor packets.MRPT MR ON ON/OFF When ON, causes the TNC to display the entire digipeatlist for monitored packets.MYCALL MY NOCALL 6 characters Specifies your call sign.+SSIDPACLEN P 128 0 - 255 Specifies the maximum length of the data portion of apacket.PACTIME PACT AFTER 10 EVERY/ If set to EVERY, sends a packet at intervals of the specifiedAFTER n period (n). If set to AFTER, sends a packet only once after( n = 0 - 250 ) the specified period of (n). The unit of n is 100 milliseconds.PERSIST PE 128 128 Specifies a parameter to calculate probability for thePERSIST/SLOTTIME method.PPERSIST PP ON ON Causes the TNC to use the PERSIST/SLOTTIME method when ON, or the DWAIT method when OFF.
47Command form Default Parameters DescriptionName ShortRESET RESET - - Restores the default status for all the commands.RESPTIME RES 5 5 Specifies the acknowledgement packet transmission delay.The unit of the parameter is 100 milliseconds.RESTARTRESTART- - Causes the TNC function as if it is switched OFF then ON.RETRY RE 10 10 Specifies the number of transmission retries. If packets arenot correctly accepted while connected, a connect requestis sent again after the specified number of retries.SENDPAC SE $0D $0D Specifies a character that forces a packet to be sent.SLOTTIME SL 3 3 Specifies the period of random number generation intervalsfor the PERSIST/SLOTTIME method. The unit of the pa-rameter is 10 milliseconds.TRACE TRAC OFF OFF When ON, causes the TNC to display all received packetsin their entirety.TRIES TRI 0 0 Specifies the number of transmission retries programmedin the retry counter.TXDELAY TX 50 50Specifies the time delay between PTT ON and start oftransmission.
