MT-4E VHF & UHF Receiver & Transmitter Instruction ManualIM08-MT-4E-TXRX-P1162iiiRF Exposure WarningExposure to radio frequency (RF) energy has been identied as a potential environmental factor that must be considered before a radio transmitter can be authorized or licensed. The FCC and IC have therefore developed maximum permissible exposure (MPE) limits for eld strength and power density, listed in FCC 47 CFR 1.1310 and IC RSS-102 Issue 2 Sect 4. The FCC has furthermore determined that determination of compliance with these exposure limits, and preparation of an Environmental Assessment (EA) if the limits are exceeded, is necessary only for facilities, operations and transmitters that fall into certain risk categories, listed in FCC 47 CFR 1.1307 (b), Table 1. All other facilities, operations and transmitters are categorically excluded from making such studies or preparing an EA, except as indicated in FCC 47 CFR 1.1307 (c) and (d).Revised FCC OET Bulletin 65 (Edition 97-01) and IC RSS-102 Issue 2 provide assistance in determining whether a proposed or existing transmitting facility, operation or device complies with RF exposure limits. In accordance with OET Bulletin 65, FCC 47 CFR 1.1307 (b) and RSS-102 Issue Sect 2.5, this Daniels Electronics Ltd. transmitter is categorically excluded from routine evaluation or preparing an EA for RF emissions and this exclusion is sufcient basis for assuming compliance with FCC/IC MPE limits. This exclusion is subject to the limits specied in FCC 47 CFR 1.1307 (b), 1.1310 and IC RSS-102 Issue 2 Sect 4. Daniels Electronics Ltd. has no reason to believe that this excluded transmitter encompasses exceptional characteristics that could cause non-compliance. Notes: • The FCC and IC’s exposure guidelines constitute exposure limits, not emission limits. They are relevant to locations that are accessible to workers or members of the public. Such access can be restricted or controlled by appropriate means (i.e., fences, warning signs, etc.). • The FCC and IC’s limits apply cumulatively to all sources of RF emissions affecting a given site. Sites exceeding these limits are subject to an EA and must provide test reports indicating compliance.RF Safety Guidelines and InformationBase and Repeater radio transmitters are designed to generate and radiate RF energy by means of an external antenna, typically mounted at a signicant height above ground to provide adequate signal coverage. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (EIRP) is not more than that permitted for successful communication. The following antenna installation guidelines are extracted from Appendix A from OET Bulletin 65 and must be adhered to in order to ensure RF exposure compliance:Non-building-mounted Antennas: Height above ground level to lowest point of antenna ≥ 10 m or Power ≤ 1000 W ERP (1640 W EIRP)Building-mounted Antennas: Power ≤ 1000 W ERP (1640 W EIRP)The following RF Safety Guidelines should be observed when working in or around transmitter sites: • Do not work on or around any transmitting antenna while RF power is applied. • Before working on an antenna, disable the appropriate transmitter and ensure a “DO NOT USE” or similar sign is placed on or near the PTT or key-up control. • Assume all antennas are active unless specically indicated otherwise. • Never operate a transmitter with the cover removed. • Ensure all personnel entering a transmitter site have electromagnetic energy awareness training.For more information on RF energy exposure and compliance, please refer to the following: 1. FCC Code of Regulations; 47 CFR 1.1307 and 1.1310. 2. FCC OET Bulletin 65, Edition 97-01, “Evaluating Compliance with FCC Guidelines for Human Exposure to Radiofrequency Electromagnetic Fields.” 3. http://www.fcc.gov/oet/rfsafety/. 4.

MT-4E VHF & UHF Receiver & Transmitter Instruction ManualIM08-MT-4E-TXRX-P11621INTRODUCTIONThe MT-4E Receiver and Transmitter are FM radio modules capable of analog operation in 12.5 kHz (narrow band) or 25 kHz (wide band) channels. A rmware upgrade may be purchased to allow P25 Digital operation. Modular design allows each of the receiver and transmitter’s internal modules to be individually assembled and tested, which facilitates construction, tuning and general maintenance.The MT-4E Receiver and Transmitter combine state of the art performance in a compact modular enclosure for applications ranging from remote mountain top repeaters to congested urban radio environments. Each module is characterized by dependable, low maintenance performance under the most severe environmental conditions.The MT-4E Receiver and Transmitter are primarily software controlled radio modules, allowing tuning, programming and maintenance to be done via software service with few hardware adjustments required.The MT-4E series is compatible with all Daniels’ subrack and base station enclosures. It supports a basic analog interface and may be used in a mixed system with MT-3 and MT-4 series receivers and transmitters.P25 Digital Mode When the P25 rmware upgrade is purchased, the MT-4E family of receivers and transmitters may be congured for P25 Digital operation, or mixed mode operation. In a repeater conguration, the receiver passes the complete P25 Digital voice packet directly to the transmitter so no P25 Digital information is lost.All P25 specications, operational description and information contained in this instruction manual require the P25 rmware upgrade to function. If the MT-4E Receiver and Transmitter are purchased without the P25 rmware upgrade, the radio will program and operate in analog mode only.NOTE: This equipment is not to be operated within the frequency band 406–406.1 MHz unless specically authorized by the Federal Communications Commission or Industry Canada in conjunction with COSPAS / SARSAT.GENERAL INFORMATIONNOTE: The General Information and the Theory of Operation sections are common for all models of MT-4E Receivers and Transmitters. Information that is specic to individual models will be identied where relevant.

MT-4E VHF & UHF Receiver & Transmitter Instruction ManualIM08-MT-4E-TXRX-P1162General Information2Secure CommunicationsThe receiver and transmitter are capable of decoding and encoding secure communications if a DES-OFB / AES Encryption Module is installed. To successfully decode or encode a transmission, the encryption module must be programmed with a valid encryption key using the Motorola KVL 3000 Plus Keyloader in conjunction with a Daniels Keyloader Cable. The Daniels Keyloader Cable plugs into the front panel RJ45 jack on the front of the receiver or transmitter module.Consult Keyloader instructions for details on loading a key. A loaded key may be zeroized by pulling the CLEAR KEYS 1, then the CLEAR KEYS 2 inputs to ground 500 ms apart. Alternately, the CI-BC-4E Base Controller or Universal Interface Card (UIC) may be used to clear the keys for all modules in a system with a single key press of the switch marked ZEROIZE KEY. The CI-BC-4E Base Controller can also be used to control whether the transmitter outputs a secure or a clear signal.Firmware UpgradesReceiver and transmitter rmware upgrading is performed with the PC-based rmware ashing software. A USB Type A to 5-pin Mini-B cable is used to connect the USB port of an IBM-compatible computer to the USB port on the front panel of the receiver or transmitter module.Firmware upgrades can be found on the Daniels Electronics Ltd. website at www.danelec.com.MT-4E Receiver Family ModelsFollowing are the models in the MT-4E Receiver family: VR-4E150-00-000 UR-4E460-00-000VR-4E150-A0-000 UR-4E460-A0-000UR-4E380-00-000 UR-4E500-00-000UR-4E420-00-000 UR-4E768-00-000UR-4E420-A0-000 UR-4E800-00-000UR-4E440-00-000 UR-4E850-00-000MT-4E Transmitter Family ModelsFollowing are the models in the MT-4E Transmitter family: VT-4E150-00-800UT-4E380-00-600UT-4E450-00-800UT-4E500-00-800UT-4E850-00-300UT-4E900-00-300

MT-4E VHF & UHF Receiver & Transmitter Instruction ManualIM08-MT-4E-TXRX-P1162General Information 3CHANNEL AND BANK SELECTIONFour channel select lines, CSEL 0 – CSEL 3, from the motherboard are brought into the receiver and transmitter modules by the 48-pin rear connector, allowing selection of 16 different channels. These signals are normally pulled low in the receiver and transmitter, but are typically set by jumpers on the motherboard to select Channel 1 by default. In addition, a bank select input is provided to switch between Bank A and B, each of which has 16 channels. The Bank select line normally oats high (+5 V), selecting Bank A, but may be pulled low or high externally to select Bank B.Channel and Bank Select Line MappingThe table below shows the relationship between the states of the bank and channel select lines. Note that the channel select lines follow a binary pattern, but that the binary “0” represents Channel 1. The Bank A/B select line normally oats high (+5 V), selecting Bank A, but may be pulled low or high externally via the Bank A/B select line.BANK A/B CSEL 3 CSEL 2 CSEL 1 CSEL 0BANK SELECTEDCHANNEL SELECTEDHI LO LO LO LO A 1HI LO LO LO HI A 2HI LO LO HI LO A 3HI LO LO HI HI A 4HI LO HI LO LO A 5HI LO HI LO HI A 6HI LO HI HI LO A 7HI LO HI HI HI A 8HI HI LO LO LO A 9HI HI LO LO HI A 10HI HI LO HI LO A 11HI HI LO HI HI A 12HI HI HI LO LO A 13HI HI HI LO HI A 14HI HI HI HI LO A 15HI HI HI HI HI A 16LO LO LO LO LO B 1LO LO LO LO HI B 2LO LO LO HI LO B 3LO LO LO HI HI B 4LO LO HI LO LO B 5LO LO HI LO HI B 6LO LO HI HI LO B 7LO LO HI HI HI B 8LO HI LO LO LO B 9LO HI LO LO HI B 10LO HI LO HI LO B 11LO HI LO HI HI B 12LO HI HI LO LO B 13LO HI HI LO HI B 14LO HI HI HI LO B 15LO HI HI HI HI B 16

Once RSS is downloaded with either the full or demo version, click Help to access the help les.Receiver and transmitter programming is performed with the PC-based RSS. A USB Type A to 5-pin Mini-B cable (included with the software) is used to connect the USB port of an IBM-compatible computer to the USB port on the front panel of the receiver or transmitter module. The RSS allows the receiver or transmitter to be programmed for: • operating frequencies • CTCSS and DCS signaling • P25 Digital settings, such as NAC and TGID • modulation type • many other parametersSystem Recommendations: • Microsoft Windows 2000 • Microsoft Windows XPRecommended Minimum Specication: • Pentium III Processor – 500 MHz • 256 MB Memory (RAM) • 1 GB Free Disk Space

MT-4E VHF & UHF Receiver & Transmitter Instruction ManualIM08-MT-4E-TXRX-P1162Radio Service Software Programming6InstallationThe RSS should install automatically once the CD is inserted. If not, run SETUP.EXE, located on the CD.NOTE: The receiver and transmitter must be programmed separately.Once the connections are made, the RSS may be run on the computer and the radio switched on. The rst time a receiver or transmitter is connected, the USB drivers will need to be installed from the CD using the Hardware Update Wizard.To test the connection:Choose the appropriate module from the Select Device drop-down list.1. Click 2. Congure on the main screen to open the Receiver or Transmitter Conguration window.Click 3. Rx ID (or Tx ID).Click 4. Read.The serial number, model number, rmware version and last programmed date should appear in the appropriate elds.RSS Programming ModeProgramming options are divided into two categories – Global Settings and Channel Settings. When the receiver or transmitter menu is selected from the main screen, both the global and channel settings for the current channel are displayed. The RSS may be used to save a receiver or transmitter conguration to disk. This function allows the user to save a standard conguration and use it as a starting conguration for all modules. An archive of congurations from each radio system in operation may also be kept so that replacement radios can be programmed easily.NOTE: If the MT-4E Receiver or Transmitter is purchased without the P25 Digital rmware upgrade, the P25 Digital options will not be available in the RSS.RSS Service ModeRSS Service Mode allows tuning, testing and setup of the receiver and transmitter modules. Analog and P25 Digital test modes, such as Bit Error Rate testing and Test Patterns generation can be selected by the RSS. Audio Levels, RF Power Output and Reference Oscillator adjustments can also be performed in RSS Service Mode.

MT-4E VHF & UHF Receiver & Transmitter Instruction ManualIM08-MT-4E-TXRX-P11627RADIO SYSTEM CONFIGURATIONSREPEATERThe MT-4E series receivers and transmitters may be congured in a repeater conguration. The standard way of setting up a repeater system is to connect the receiver to the transmitter through a Radio Interconnect Cable plugged into the RJ45 CNTL BUS connectors on the front panels of each radio module. This cable routes analog and digital COR / PTT signals and LVDS Serial Data from the receiver to the transmitter in both analog and P25 Digital mode. The Radio Interconnect Cable may be connected directly from the receiver to the transmitter, or may be routed through a Repeater Control Card.A typical conguration is to set up the repeater to re-transmit an incoming signal in the same mode as it is received (i.e., normally, you would want a received analog signal to be repeated as analog and a received digital signal to be repeated as digital). This requires the receiver and transmitter modules to be programmed in Mixed Mode of operation through the RSS. The repeater may also be programmed to operate in analog or P25 Digital mode only.Mixed Mode Repeat operation occurs as follows: 1. The receiver determines whether an incoming signal is analog or digital and asserts either the ANALOG COR or DIGITAL COR signal line on the front panel RJ45 CNTL BUS connector. LVDS Serial Data is sent to the RJ45 CNTL BUS connector as well.2. The COR signal and LVDS Serial Data are transferred over the Radio Interconnect Cable directly to the transmitter or are routed through a Repeater Control Card.3. The transmitter senses the incoming ANALOG PTT or DIGITAL PTT signal from the front panel RJ45 CNTL BUS connector and keys up in analog mode or P25 Digital mode. LVDS Serial Data is routed through the transmitter for transmission.An alternate way of setting up a repeater system is to connect the receiver to the transmitter through an Audio Control Card or Base Controller. These control cards route analog audio and a single COR / PTT signal from the receiver to the transmitter. This conguration is recommended for analog repeater systems only.The receiver and transmitter have no connection between them apart from the audio (Audio Control Card or Base Controller only), COR / PTT signals and LVDS Serial Data lines. The transmitter does not get any information from the receiver about which frequency or channel number to key up on. The receiver and transmitter channel is determined by the state of the channel select lines and bank select line.

An Audio Control Card or Base Controller is added to the system for E&M control. For tone remote control of the system, a Tone Remote Adapter is added to the system along with the base controller. The audio control card or the base controller will also allow for repeat capability of the system using analog audio as the repeat path.The base controller is used for system control of encryption and decryption of the P25 Digital voice messages. Optional decryption or encryption modules are required in the receiver and transmitter modules.DIGITAL FIXED (BASE) STATION INTERFACEThe MT-4E series receivers and transmitters may be congured in a xed (or base) station conguration with a digital interface. A universal interface card (UIC) is added to the system for Ethernet control.

MT-4E VHF & UHF Receiver & Transmitter Instruction ManualIM08-MT-4E-TXRX-P116211VHF & UHF HARDWARE TUNING AND TROUBLESHOOTINGREPAIR NOTEMT-4E Receivers and Transmitters employ a high percentage of surface mount components which should not be removed or replaced using an ordinary soldering iron. Removal and replacement of surface mount components should be performed only with specically designed surface mount rework and repair stations complete with Electrostatic Discharge (ESD) protection.When removing surface mount solder jumpers, it is recommended to use solder wick braid in place of vacuum-type de-soldering tools. This will help prevent damage to the circuit boards.

An optional decryption module can be installed in the receiver.The following steps will help you determine the most likely sub-assembly that contains a fault and may help you determine why the fault is occurring. NOTE: The sub-assembly or the entire receiver can be sent back to Daniels Service section for repair. Contact Daniels Service section before returning any product.Before testing, the receiver should be in the subrack or connected to the subrack by means of an Extender Card or kit. The main power to the system (+13.8 VDC) and the +9.5 VDC regulated supply should be checked via the front panel of the system regulator. Testing the Receiver1. Flip the receiver front panel ON/OFF switch from the OFF position to the NORM position.2. Check that the two front panel LEDs both turn ON for less than ve seconds and then turn OFF. If this is not the case, the most likely fault is on the UDB, on the synthesizer, or on the receiver mainboard. Make sure that the UDB and the synthesizer module are properly seated on the receiver mainboard.3. Connect the receiver to the PC with the USB cable and run the Radio Service Software (RSS).4. Select [P25 or Analog] Receiver.5. Click Congure. 6. Click Read to read the receiver conguration. If the RSS returns “Device Not Responding,” physically inspect the USB cable and connection, check the Daniels USB driver and check that the USB is recognized by the Device Manager. If the RSS still does not recognize the connection, the most likely fault is on the UDB.7. Click Rx ID.8. Click Read to read the Receiver ID. Conrm that the Frequency Band in the Synthesizer ID Model Number matches the Frequency Band in the Receiver Global Settings. If the settings do not match, the synthesizer will require replacement or the programming will need to be changed to match the synthesizer hardware.If the receiver is still not functioning properly, the module level check should be conducted in the following order.

At this level of fault diagnosis it is not feasible to isolate the problem between the two units.If the receiver front panel ON/OFF switch is set from the OFF position to the NORM position and the two front panel LEDs stay on, check that the synthesizer and the UDB are properly seated on the receiver mainboard and check the following test points on the UDB. To access the UDB, the shield lid covering the UDB will need to be removed. Test Point Signal Monitored Typical voltageTP1 Ground 0 VDCTP2 Logic power +3.3 VDC ± 5%TP3 DSP core supply +1.2 VDC ± 5%TP4 CPLD core supply +1.8 VDC ± 5%If the UDB voltages are not within the specied tolerances, it is most likely that the receiver mainboard (which supplies these voltages to the UDB) is faulty or there is a short within the UDB.If the UDB voltages are within the specied tolerances, inject a -70 dBm carrier on the receiver frequency into the RF input and check the RSSI meter reading in RSS Service mode. If the RSSI meter reading is low (< 30), perform the following test to verify that the synthesizer is locked on frequency:Disconnect the LO output SMB connector from the synthesizer to the RF Preselector and connect the synthesizer LO output to a radio communication test set. Conrm that the synthesizer LO frequency matches the Target Synthesizer RF OUT found in the “Reference Oscillator” eld of RSS Service mode. The LO output should be approximately +7 dBm.The frequency of the synthesizer LO output will be above or below the receiver frequency by the IF frequency (see the VHF and UHF Receiver Performance Specications data sheet). Check that this output is within the tolerance for the local oscillator frequency stability (see the VHF and UHF Receiver Performance Specications data sheet). Also ensure that the RF frequency will change with programmed channel changes in the RSS.Receiver RF PreselectorCheck the +9.5 VDC power supply wire to the RF Preselector. The supply voltage should be +9.5 VDC ± 5 %. Inject a -30 dBm carrier on the receiver frequency into the RF Input and check that the IF Output of the RF Preselector is equal to the specied IF frequency (see the VHF and UHF Receiver Performance Specications data sheet) and the output can be demodulated through the communication test set. If this is not the case, the synthesizer or the RF Preselector, or both, are faulty.To further isolate the fault, the LO output can be disconnected from the synthesizer and an LO input can be applied from an external source to the RF Preselector. The frequency of the external LO input should be the Target Synthesizer RF OUT found in the “Reference Oscillator” eld of RSS Service mode. Check the 21.4 MHz output of the module using a communication test set.

MT-4E VHF & UHF Receiver & Transmitter Instruction ManualIM08-MT-4E-TXRX-P1162VHF & UHF Hardware Tuning and Troubleshooting18TRANSMITTER TROUBLESHOOTINGThe transmitter is composed of four main components: the transmitter mainboard, the synthesizer module, RF power amplier and universal daughter board (UDB). An optional encryption module can also be installed in the transmitter.The following steps will help you determine the most likely sub-assembly that contains a fault and may help you determine why the fault is occurring. NOTE: The sub-assembly or the entire transmitter can be sent back to Daniels Service section for repair. Contact Daniels Service section before returning any product.Before testing, the transmitter should be in the subrack or connected to the subrack by means of an extender card or kit, and the main power to the system (+13.8 VDC) and the +9.5 VDC regulated supply should be checked via the front panel of the system regulator. The transmitter RF output should be terminated with a 50 Ω load of appropriate wattage or communications test set.Testing the Transmitter1. Flip the transmitter front panel NORM/ OFF/ KEY TX switch from the OFF position to the NORM position 2. Check that the two front panel LEDs both turn ON for less than two seconds and then turn OFF. If this is not the case or the transmitter is not functioning properly, the following steps can be taken.3. Connect the transmitter to the PC with the USB cable4. Run the Radio Service Software (RSS). 5. Select [P25 or Analog] Transmitter.6. Click Congure.5. Click Read to read the transmitter conguration. If the RSS returns “Device Not Responding,” physically inspect the USB cable and connection, check the Daniels USB driver and check the connection through the Device Manager. If the RSS still does not recognize the connection, the most likely fault is on the UDB.6. Click Tx ID.7. Click Read to read the transmitter ID. Conrm that the frequency band in the Synthesizer ID Model Number matches the frequency band in the Transmitter Global Settings. If the settings do not match, the synthesizer will require replacement or the programming will need to be changed to match the synthesizer hardware.If the transmitter is still not functioning properly, the module level check should be conducted in the following order.

MT-4E VHF & UHF Receiver & Transmitter Instruction ManualIM08-MT-4E-TXRX-P1162VHF & UHF Hardware Tuning and Troubleshooting 19Transmitter MainboardCheck the following test points on the transmitter mainboard:Test Point Signal Monitored Typical VoltageTP1 Voltage from Motherboard +13.8 VDC Line +13.8 VDC**TP2 Regulated +9.5 VDC from Motherboard +9.5 VDC ± 5 %TP3 USB Connector Power +3.0 VDC or +5.0 VDCTP4 Switched +13.8 VDC Line from Front Panel Switch +13.8 VDC**Test Points are shown on the VHF / UHF Transmitter Jumper and Test Point Locator Illustrations.If the test point voltages are within the specied range, it is most likely that the transmitter mainboard is not the source of problem. Proceed to the following step.Synthesizer and UDB ModulesThe synthesizer module and UDB are bound together through their communication link. At this level of fault diagnosis it is not feasible to isolate the problem between two units.If the transmitter front panel NORM/OFF/ KEY TX switch is set from the OFF position to the NORM position and the two front panel LEDs stay on, check that the synthesizer and the UDB are properly seated on the transmitter mainboard and check the following test points on the UDB. To access the UDB, the amplier sub-assembly and the shield lid covering the UDB will need to be removed:Test Point Signal Monitored Typical VoltageTP1 Ground 0 VDCTP2 Logic power +3.3 VDC ± 5 %TP3 DSP core supply +1.2 VDC ± 5 %TP4 CPLD core supply +1.8 VDC ± 5 %Test Points are shown on the VHF / UHF Transmitter Jumper and Test Point Locator Illustrations.If the UDB voltages are not within the specied tolerances, the transmitter mainboard (that supplies these voltages to the UDB) is most likely faulty. If the UDB voltages are within the specied tolerances, it is likely that the synthesizer or the UDB, or both, are faulty.If the transmitter front panel NORM/OFF/ KEY TX switch is set from the OFF position to the NORM position; the two front panel LEDs both turn ON for less than two seconds and then turn OFF; and the RF output power control is set at its maximum in the “Power Levels” eld of RSS Service mode, but the RF output power is considerably less than 8.0 W:• Ensure that Synthesizer Reference is set to Internal in the “Jumper Settings” eld of RSS Service mode.• Ensure that the output of the synthesizer module on the RF cable is 0 dBm (± 2 dBm) and that the RF frequency will change with programmed channel changes in the RSS. If this is not the case, it is likely that the synthesizer or the UDB, or both, are faulty. ** Refer to the Specication Data Sheets (located in this manual) for the full Supply Voltage range.

MT-4E VHF & UHF Receiver & Transmitter Instruction ManualIM08-MT-4E-TXRX-P1162VHF & UHF Hardware Tuning and Troubleshooting20Transmitter AmplierSet the front panel switch on the transmitter to KEY TX and check that the transmitter output power is approximately 0.5 to 8.0 W for VHF and UHF models.Check the following pins on Connector J1 (while the transmitter is keyed):Pin Signal Monitored Typical Voltage1RF Enable / Power Control (+0.5 to +3.0 VDC corresponds to 0.5 to 8.0 W RF Power Output)+0.5 to +3.0 VDC2 Regulated +9.5 VDC from motherboard +9.5 VDC ± 5%3 Voltage from motherboard +13.8 VDC line +13.8 VDC**If Pin 1 is not within tolerance, the most likely fault is in the UDB or synthesizer module. If Pins 1, 2 and 3 are within the specied tolerances and there is no RF output power, the most likely fault is in the amplier.To test the RF power amplier sub-assembly, set the output power to maximum using “Power Level Adjustments” in RSS Service mode, and drive the input of the amplier with a 0 dBm RF signal. Check that the RF power output is 8.0 W when the front panel switch is set to KEY TX.SYSTEM TROUBLESHOOTINGIf the radio system is not receiving or transmitting on the right frequency, check the Channel and Bank Select lines of the receiver and transmitter modules. The motherboard has jumpers that allow one of 16 channels to be selected on a receiver or transmitter. The factory default is to have them all set to ground the channel select lines CSEL 0 through CSEL 3, forcing the radio to operate on Channel 1. On the receiver and transmitter there is also a Bank A/B line which usually oats high – selecting Bank A. The receiver and transmitter have separate control of their channel select lines, so changing receiver channels does not affect the transmitter channel.If the Radio Service Software is failing partway through a read or write of the receiver, check that the receiver is not squelching and unsquelching repeatedly during the read or write operation. Disconnect the RF signal source from the receiver during the read or write operation.** Refer to the Specication Data Sheets (located in this manual) for the full Supply Voltage range.
