This radio features (2) programmable front panel buttons and a single digit alpha-numeric LED display. Each channel can be programmed to contain a unique set of operating frequencies and options. These options include industry standard signaling formats: Quiet Call, Digital Quiet Call, Selcall(5 Tone/7 Tone), DTMF and 2-Tone. INSPECTION The radio package includes a Ritron mobile radio, microphone, and mounting kit. Review the installation instructions in the mounting kit for a complete list of parts included. Examine all of the equipment immediately after delivery and report any damages to the shipping company. MODEL IDENTIFICATION RPM-160/RPM-460 The label attached to the back of the mobile includes both the FCC and Canadian identification numbers, radio serial number, radio model number, and operating frequency range. Ritron’s address, telephone number, and website are also included on the label. OWNER INFORMATION_____________________________________________ FCC REGULATIONS The FCC requires you to obtain a station license for your radios before using the equipment to transmit. The station licensee is responsible for ensuring that transmitter power, frequency, and deviation are within the limits specified by the station license. The station licensee is also responsible for proper operation and maintenance of his radio equipment. This includes checking the transmitter frequency and deviation periodically, using approved methods. Your RITRON dealer can help you obtain an FCC license. To receive an FCC license for VHF or UHF frequencies, you must submit FCC application Form 600. HOW TO OBTAIN AN FCC RADIO LICENSE Because your Ritron radio operates on Private Land Mobile frequencies, it is subject to the Rules and Regulations of the FCC, which requires all operators of these frequencies to obtain a station license before operating their equipment. Make application for your FCC license on FCC Forms 600 and 159. To have forms and instructions faxed to you by the FCC, call the FCC Fax-On-Demand system at 202-418-0177 from your fax machine; request Document 000600 & Form 159. To have Document 000600 & Form 159 mailed to you, call the FCC Forms Hotline at 800-418-FORM (800-4183676). For help with questions concerning the license application, contact the FCC at 888-CALL-FCC (888-225-5322). You must decide which radio frequency(s) you can operate on before filling out your application. For help determining your frequencies, call RITRON at 800-USA-1-USA (800-872-1872). SAFETY STANDARDS The FCC (with its action in General Docket 79-144, March 13, 1985) has adopted a safety standard for human exposure to radio frequency electromagnetic energy emitted by FCC regulated equipment. Ritron observes these guidelines and recommends that you do so also: • DO NOT operate a mobile radio transmitter when someone outside the vehicle is within two feet of the antenna. • DO NOT transmit with a fixed radio(base station, microwave, rural telephone RF equipment) or marine radio when someone is within two feet of the antenna. • DO NOT operate any radio transmitter unless all RF connectors are secure and any open connectors are properly terminated. • DO NOT operate radio equipment near electrical blasting caps or in an explosive atmosphere. • GROUND ALL RADIO EQUIPMENT according to RITRON’s installation sheet. • RITRON products should be repaired only by RITRON authorized personnel. RF EXPOSURE RF WARNING STATEMENT: The following statement appears in the Users Manual regarding RF safety: RF ENERGY EXPOSURE AWARENESS AND CONTROL INFORMATION, AND OPERATIONAL INSTRUCTIONS FOR FCC OCCUPATIONAL USE REQUIREMENTS BEFORE USING YOUR MOBILE 2-WAY RADIO, READ THIS IMPORTANT RF ENERGY AWARENESS AND CONTROL INFORMATION AND OPERATIONAL INSTRUCTIONS TO ENSURE COMPLIANCE WITH THE FCC’S RF EXPOSURE GUIDELINES. NOTICE: This radio is intended for use in occupational/controlled conditions, where users have full knowledge of their exposure and can exercise control over their exposure to meet FCC limits. This radio device is NOT authorized for general population, consumer, or any other use. This 2-way radio uses electromagnetic energy in the radio frequency (RF) spectrum to provide communications between two or more users over a distance. It uses radio frequency (RF) energy or radio waves to send and receive calls. RF energy is one form of electromagnetic energy. Other forms include, but are not limited to, electric power, sunlight and x-rays. RF energy, however, should not be confused with these other forms of electromagnetic energy, which when used improperly can cause biological damage. Very high levels of x-rays, for example, can damage tissues and genetic material. Experts in science, engineering, medicine, health and industry work with organizations to develop standards for exposure to RF energy. These standards provide recommended levels of RF exposure for both workers and the general public. These recommended RF exposure levels include substantial margins of protection. All 2-way radios marketed in North America are designed, manufactured and tested to ensure they meet government established RF exposure levels. In addition, manufacturers also recommend specific operating instructions to users of 2-way radios. These instructions are important because they inform users about RF energy exposure and provide simple procedures on how to control it. Please refer to the following websites for more information on what RF energy exposure is and how to control your exposure to assure compliance with established RF exposure limits. http://www.fcc.gov/oet/rfsafety/rf-faqs.html http://www.osha.gov/SLTC/radiofrequencyradiation/index.html Federal Communications Commission Regulations The FCC rules require manufacturers to comply with the FCC RF energy exposure limits for mobile 2way radios before they can be marketed in the U.S. When 2-way radios are used as a consequence of employment, the FCC requires users to be fully aware of and able to control their exposure to meet occupational requirements. Exposure awareness can be facilitated by the use of a label directing users to specific user awareness information. Your Ritron RPM 60 Series Mobile Radio has a RF exposure product label. Also, your Ritron RPM 60 Series Owners Manual includes information and operating instructions required to control your RF exposure and to satisfy compliance requirements. Compliance with RF Exposure Standards Your Ritron RPM 60 Series Mobile Radio is designed and tested to comply with a number of national and international standards and guidelines (listed below) regarding human exposure to radio frequency electromagnetic energy. This radio complies with the IEEE and ICNIRP exposure limits for occupational/controlled RF exposure environment at duty factors of up to 50% talk- 50% listen and is authorized by the FCC for occupational use. In terms of measuring RF energy for compliance with the FCC exposure guidelines, your radio antenna radiates measurable RF energy only while it is transmitting (during talking), not when it is receiving (listening) or in standby mode. Your Ritron RPM 60 Series Mobile Radio complies with the following RF energy exposure standards and guidelines: • United States Federal Communications Commission, Code of Federal Regulations; 47 CFR §§ 2 subpart J. • American National Standards Institute (ANSI) / Institute of Electrical and Electronic Engineers (IEEE) C95. 1-1992. • Institute of Electrical and Electronic Engineers (IEEE) C95.1-1999 Edition. RF Exposure Compliance and Control Guidelines and Operating Instructions To control exposure to yourself and others and ensure compliance with the occupational/controlled environment exposure limits always adhere to the following procedures. Guidelines: • User awareness instructions should accompany device when transferred to other users. • Do not use this device if the operational requirements described herein are not met. Instructions: • Transmit no more than the rated duty factor of 50% of the time. To transmit (talk), push the Push-ToTalk (PTT) button. To receive calls, release the PTT button. Transmitting 50% of the time, or less, is important because this radio generates measurable RF energy exposure only when transmitting (in terms of measuring for standards compliance). • Transmit only when people outside the vehicle are at least the recommended minimum lateral distance away, as shown in Table 1, from a properly installed, according to installation instructions, externallymounted antenna. NOTE - Table 1 lists the recommended minimum lateral distance for bystanders in an uncontrolled environment from transmitting types of antennas (i.e., monopoles over a ground plane, or dipoles) at several different ranges of rated radio power for mobile radios installed in a vehicle. Table 1. Rated Power and Recommended Lateral Distance Rated Power of VehicleInstalled Mobile Two-way Radio Less than 7 watts 7 to 15 watts 16 to 50 watts Recommended Minimum Lateral Distance from Transmitting Antenna 6 in (21 cm) 9 in (31 cm) 16 in (57 cm) Mobile Antennas • Antenna Installation – Locate and install the antenna in the center of a large metal area such as the vehicle roof or trunk deck. NOTE: Take into account the bystander exposure conditions of frontseat and backseat passengers and persons standing outside the vehicle according to the recommended minimum lateral distances in table 1. These mobile antenna installation guidelines are limited to metal body motor vehicles or vehicles with appropriate ground planes. Additionally, when installing the antenna: a.) Take into account the installation requirements of the antenna manufacturer/supplier. b.) Refer to the Ritron Mobile Radio Installation Guide found in the Ritron RPMK-12 (RPM Installation Kit) that is included with your RPM 60 Series Mobile Radio. • Use only Ritron approved supplied antenna or Ritron approved replacement antenna. Unauthorized antennas, modifications, or attachments could damage the radio and may violate FCC regulations. Approved Accessories • This radio has been tested and meets the FCC RF exposure guidelines when used with the Ritron accessories supplied or designated for this product. Use of other accessories may not ensure compliance with the FCC’s RF exposure guidelines, and may violate FCC regulations. • For a list of Ritron approved accessories, refer to the Accessories section of this Manual, or visit the following website which lists approved accessories: http:www.ritron.com, or contact the radio manufacturer at 1-800-USA-1USA. • This device has been designed to operate with the antennas list in the Accessories section, and having a maximum gain of 3dB. Antennas not included in this list or having a gain greater than 3dB are strictly prohibited for use with this device. The required antenna impedance is 50 ohms. • 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. Contact Information For additional information on exposure requirements or other information, contact Ritron, Inc. SAFETY PRECAUTIONS RADIO MOUNTING LOCATION Consider driver and passenger safety when you choose a location for the radio. Do not mount the unit overhead or on a sidewall unless you take special precautions, such as securing the radio with a safety strap. Improper installation increases the possibility that a car accident could dislodge the radio and make it a dangerous projectile. VEHICLE OPERATION • ELECTRONIC SYSTEMS – Check the vehicle’s manual for possible warnings about operating a two-way radio in a vehicle equipped with an electronic ignition or anti-skid braking system. • LIQUEFIED PETROLEUM (LP) GAS FUEL SYSTEM – Radio installation in a vehicle fueled by liquefied petroleum (LP) gas (with the LP gas container stored in a sealed-off space, such as a trunk) must conform to NFPA (National Fire Protection Association) standard 58. • BATTERY POWER – Avoid leaving the radio turned on for long periods when the engine is off, as this could run down the vehicle’s battery. RADIO CARE GENERAL • MOISTURE – The mobile is not waterproof and should not be exposed to rain, or immersed. • EXTREME HEAT – Like all electronic equipment, the mobile should not be subjected to extreme heat, such as being exposed to direct sunlight in a closed vehicle. • • VIBRATION/SHOCK – Although your Ritron mobile is designed to be rugged, it should not be expected to survive abuse. Avoid dropping the radio. • CHEMICALS – Detergents, alcohol, aerosol sprays, and/or petroleum products may damage the front panel and/or case. Clean the mobile’s exterior using a soft cloth moistened with water. SERVICE Federal law prohibits you from making any internal adjustments to the transmitter, and from changing transmit frequencies unless you are specifically designated by the licensee.

Antenna Connector External DC Power Connector External Speaker Jack EXTERNAL DC POWER CONNECTOR The RPM mobile is powered from the back of the radio through a 2-pin connector. The power source must be capable of delivering 10 Amps @ 11-16VDC. OPERATION______________________________________________________ WHAT THE RADIO TONES MEAN The RITRON RPM mobile responds to certain instructions by sounding a tone or series of tones. These tones can tell you whether the radio is working as you expect. Power On: Single high frequency tone when the radio is turned on. Programmable Buttons: Single high frequency tone when the button is pressed. Receive Courtesy Beep: Single high frequency tone at the end of a received call to let the user know when to reply. Transmit Clear to Talk: Single high frequency tone after the PTT is pressed to let the user know when to begin speaking. Busy Channel Lockout: A repeating single low frequency tone when the PTT is pressed while the channel is busy. Transmit Time-Out: A repeating single low frequency tone after the PTT has been pressed longer than the transmit time-out time period. 2-Tone Decode: A fast alternating high and low frequency tone when the radio has decoded a valid 2-tone signal. Start/Resume Scan: A single low frequency tone when the radio begins/resumes the channel scan function. Last Active Channel: A single low frequency tone to alert the user what channel was last received during the channel scan. Priority Scan Channel: A single high frequency tone during the channel scan to alert the user the Priority channel has been received. Out-Of-Lock: A slow alternating high and low frequency tone to alert the user the radio synthesizer is not operating correctly. Low Battery: A short high frequency tone every 20 seconds to alert the user that the supply voltage to the radio has dropped below the minimum usable voltage. Channel 1 Marker Tone: When incrementing or decrementing the channels, a long, high frequency tone to alert the user that the radio display is at Channel 1. Monitor/Squelch: If one of the programmable buttons is programmed for MONITOR and a channel is programmed for carrier, tone, or 2-Tone, when the Monitor button is pressed a single, double, or triple high frequency tone will be heard. Tone Squelch – single tone Carrier Squelch – double tone 2-Tone Squelch – triple tone CHANNEL SELECTION The RPM mobile provides 15 channels, each of which may be “dealer” programmed. The first nine channels appear on the display as 1 through 9, and the next six channels are displayed as A through F (with b, c, and d displayed as lower case letters). You can move forward or backward through the channels, depending upon the programming of the programmable buttons. If the buttons are programmed for Channel Up and Channel Down, then pressing and releasing the button programmed for Channel Up will increment the displayed channel. Pressing and releasing the button programmed for Channel down will decrement the displayed channel. If only one button is programmed for channel selection, either Channel Up or Channel Down, then pressing and releasing the button will cause the display to either increment or decrement the displayed channel. Any time the display is incremented to or decremented to Channel 1, then, a long tone is emitted to let you know you have reached Channel 1. This allows you to change channels without looking at the display. OPERATING MODES You can hear calls with the RPM mobile in receive mode, and broadcast your voice with the RPM mobile in transmit mode. RECEIVE The RPM mobile can receive broadcasts while the microphone PTT button is not being pressed. Whether you hear these broadcasts depends upon the volume and squelch settings. VOLUME: You can set the volume by one of two ways. 1. Press and release the programmable buttons while adjusting the volume control, using the tones as a reference. 2. When a received broadcast is heard, adjust the volume control to a desired level. SQUELCH: Squelch mutes the speaker so that interference from licensees outside of your group or background noise does not bother the user. There are three types of squelch in the RPM mobile. First is carrier squelch, which mutes the speaker if no on-channel transmissions strong enough for the radio to detect are present. The second is Quiet Call(coded) squelch. This mutes the speaker unless the radio detects an incoming signal that carries the same Quiet Call(QC) code as programmed for the selected channel. The third is 2-Tone decode. This mutes the speaker unless the radio detects an incoming signal that carries the same 2-Tone code as programmed for the selected channel. When you remove the microphone from the hang-up clip, Quiet Call squelch and 2-Tone decode are disabled and the radio reverts to carrier squelch, allowing all on-channel transmissions strong enough for the radio to detect to be heard. (This is true, unless the radio is programmed for Channel Monitor Lock-Out) MONITOR: Monitoring lets you hear all on-channel transmissions that are strong enough for the radio to detect. Monitoring a Channel Programmed with Quiet Call If the channel is programmed with Quiet Call coded squelch, you can monitor the channel one of two ways. 1. Remove the microphone from the hang-up clip, or; 2. Press and release the front panel button that is programmed for the Monitor function. The Monitor button may be programmed one of two ways; (see your dealer for programming) 1. Toggle - In toggle mode, when the Monitor button is pressed and released, the radio is switched between coded squelch and carrier squelch. If two beeps are heard when the button is pressed and released, the radio is in carrier squelch. If only one beep is heard when the button is pressed and released, the radio is in coded squelch. 2. Momentary – In momentary mode, when the Monitor button is pressed and held, the radio is switched to carrier squelch. When the button is released, the radio reverts back to coded squelch. You will hear 2 beeps when the button is pressed, and 1 beep when released. Monitoring a Channel Programmed with 2-Tone Decode If the channel is programmed with 2-Tone decode, you can monitor the channel one of two ways. 1. Remove the microphone from the hang-up clip, or; 2. Press and release the front panel button that is programmed for the Monitor function. The Monitor button may be programmed one of two ways; (see your dealer for programming) 1. Toggle - In toggle mode, when the Monitor button is pressed and released, the radio is switched between 2-Tone decode, coded squelch and carrier squelch. If one beep is heard when the button is pressed and released, the radio is in coded squelch. If only two beeps are heard when the button is pressed and released, the radio is in carrier squelch. If three beeps are heard, the radio is in 2-Tone decode squelch. 2. Momentary – In momentary mode, when the Monitor button is pressed and held, the radio is switched to carrier squelch. When the button is released, the radio reverts back to coded squelch. Also, you will only hear two beeps when the button is pressed then one beep when the button is released. To revert the radio back to 2-Tone decode, turn the radio off then back on. Receiving a 2-Tone Page To receive a 2-Tone page, select the channel programmed for 2-Tone decode. When the correct 2-Tone signal is received, the RPM mobile will generate a ringing tone and a “C” will be displayed in the LED display to indicate that a call was received. At this time the radio is in either tone squelch( if programmed with QC or DQC) or carrier squelch. To reply, remove the microphone from the hang-up clip and begin speaking into the microphone while pressing and holding the PTT button. When you are finished transmitting, place the microphone into the hang-up clip. If there is no activity for 16 seconds, the radio will automatically reset(if Auto Reset is enabled) to 2-Tone decode and alert you with a single beep. If you do not respond within 16 seconds after the decode ringing tone, the radio will automatically reset(if Auto Reset is enabled) to 2-Tone decode and generate a single beep. If Auto Reset is not programmed, you can reset to 2-Tone decode mode by: 1. Turning the radio off then back on. 2. If one of the front panel buttons is programmed for Monitor/Toggle, press and release the button until you hear three beeps. SCAN: Scanning allows you to continually check for transmissions on multiple channels over a short amount of time. The RPM mobile has two types of scanning. For both types of scanning, all channels that are to be scanned must be marked during programming as a scan channel. Also, in order to enable and disable scanning, one of the programmable front buttons must be programmed as a SCAN button. The first type of scan is normal scan. In normal scan, when the SCAN button is pressed and released, all channels programmed as a scan channel are incrementally checked for a received signal. If no signal is present, the display is incremented to the next channel and so on. If a signal is present, the radio stops on the channel until the signal is no longer present, and then resumes scanning. The second type of scanning is priority scan. In priority scan, when the SCAN button is pressed and released, all channels programmed as a scan channel are incrementally checked for a received signal. If no signal is present, the display is incremented to the next channel and so on. If a signal is present, the radio stops on the channel until the signal is no longer present, and then resumes scanning. Also, during the time the radio is stopped on a non-priority, the radio will automatically go to the priority channel and check for a signal. If a signal is present, it will interrupt the non-priority channel and allow you to hear the broadcast on the priority channel. When that is finished, the radio will return to the nonpriority channel to check for a signal. If no signal, the radio continues with the scanning cycle. Nuisance Channel Delete – When scanning, if a channel is busy for an abnormal amount of time, the busy channel can be temporarily deleted from the scan function by pressing and releasing the front panel button programmed for Nuisance Channel Delete. To add the channel back into the scan, simply turn the radio off and back on. NOAA WX: (This feature is only available with the RPM-160) To receive your local NOAA weather broadcast, the RPM must be programmed to your area NOAA frequency and one of the front panel buttons must be programmed for NOAA WX. Press and release the button programmed for NOAA WX and the radio will automatically begin receiving on the pre-programmed NOAA weather frequency for your area. TRANSMIT Make sure that the channel is not busy before you begin transmitting. Check the TX/Busy LED, which flashes green if the channel is busy. This occurs regardless of any code signaling programmed. Normally, you should not transmit until the channel is clear. To transmit, remove the microphone from the hang-up clip. Press and hold the PTT switch on the side of the microphone, and talk in a normal tone with the microphone held two to three inches away from your face. Pressing the PTT button activates the transmitter and lights the TX/Busy LED a constant red. If, when pressing the PTT button, error tones are heard in the speaker, check for the following conditions: 1. The channel is programmed as a Receive Only channel. 2. The channel is programmed with Busy Channel Lock-out and the channel is busy. The front panel buttons can be programmed to automatically transmit various tone signaling formats. The features available are: Encode Call tone – When the button is pressed and released, the radio transmits a ringing tone to alert users in your group that a call is coming through. Encode 2-Tone - When the button is pressed and released, the radio transmits a pre-programmed 2-Tone signal. Encode 5 or 7 tone(Selcall) - When the button is pressed and released, the radio transmits a pre-programmed 5 or 7-Tone signal. Encode DTMF ANI - When the button is pressed and released, the radio transmits a pre-programmed DTMF tone signal. The RPM mobile may also be programmed to transmit a DTMF signal every time the PTT button is pressed. Encode Emergency Call - When the button is pressed and released, the radio transmits a pre-programmed multitone signal to alert all users in your group there is an emergency. Other functions that the front panel buttons may be programmed for: Talk-Around - When the button is pressed and released, and if you are operating on a repeater channel, the radio will transmit on the receive frequency when the PTT button is pressed. This will allow you to talk in simplex mode rather than occupying the repeater frequency. High/Low Transmit Power – When the button is pressed and released, the radio’s transmit power will switch from high to low and vise versa. An “h” or “L” will appear in the display when the button is pressed to indicate the power level.
