2BLTR-TH2000Dual Band Mobile Radio

our Though friendly design for user,this transceiver is technically complicated and some features maybe be new to you.Considering this manual to be a personal tutorial from the designers,allow the manual to guide you through the learning process now,then act as a reference in the coming years. Please observe the following precautions to prevent fire, personal injury, or transceiverdamage: Do not attempt to configure your transceiver while driving,it is dangerous. This transceiver is designed for a 12V and 24V DC power supply. Do not place the transceiver in excessively dusty, humid or wet areas, nor unstablesurfaces. Please keep it away from interferential devices (suchas TV, generator etc.) Do not expose the transceiver to long periods of directsunlight nor place it close to heating applianc- es. If an abnormal odor or smoke is detected comingfrom the transceiver, turn OFF the power immedi- ately.Contact local service station or your dealer. Do not transmit with high output power for extended periods; the transceiver mayoverheat. Please contact the local authorized dealer if you have any questions.We are not responsible for any typographical errors that may by in this manual.Standard accessories may change without noice, getting your understanding for any inconveniences. When programming the transceiver,need the factory initial data firstly, and then rewrite the frequency and signaling etc.Otherwise errors may occur because of different frequency band etc. Precautions 1313 Supplied Accessories Installation Functions and features Getting Acquainted Basic operation Menu function instruction Signalings Specifications CONTENTS 01 03 10 11 18 25 29 38 Professional FM Transceiver Supplied Accessories User’s Manual Professional FM Transceiver Installation User’s Manual 02 HardwareFuse*2User's Manual*1 *1*1 123 456 789 A ENT B VFO C MR D A/B # UP 0 MUTE * DWN *1 *1 Panel bracket Microphone bracket*1 Supplied Accessories/Optional Accessories Supplied Accessories 04 05 Mobile installation To install the transceiver,select a safe,convenient location inside your vehicle thatminimizes danger to your passengers and yourself while the vehicle is in motion.Considerinstalling the unit at an appropriate position so that knees or legs will not strike it duringsudden braking of your vehicle.Try to pick a well ventilated location that is shielded fromdirect sunlight. 1.Install the mounting bracket in the vehicle using the supplied self-tapping screws(4pcs)and flat washers(4pcs). 2.Position the transceiver,hen insert and tighten the supplied hexagon SEMS screws. ■ Double check that all screws are tightened to prevent vehicle vibration from loosening the bracket or transceiver. ■ Determine the appropriate angle of the transceiver,using the screw hole positions on the side of the mounting bracket. DC Power Cable Connection NOTE:Locate the power input connector as close to the transceiver as possible. This transceiver is designed for a 12V and 24V DC power supply. Initial Installation Mobile Operation Car Battery DC Power Cable Mobile Radio +12V Ignition Switch LOCK ACC ON START 06 07 1.Route the DC power cable supplied with the transceiver directly to the vehicle's batteryterminals using the shortest path from the transceiver. ■ We recommend you do not use the cigarette lighter socket as some cigarette lighter sockets introduce an unacceptable voltage drop. ■ The entire length of the cable must be dressed so it is isolated from heat,moisture,and the engine secondary (high voltage)ignition system/cables.2.After installing cable,in order to avoid the risk of damp,please use heat-resistant tap totie together with fuse box.Don't forget to reinforce whole cable. The transceiver will return to its normal operation when the power is switched ON orrepeat above operation. Antenna Connection Before operating,installan efficient,well-tuned antenna.The success of your installationwill depend largely on the type of antenna andits correct installation.The transceiver cangive excellent results if the antenna system and its installation are given careful attention.Use a 50Ω impedance antenna and lowHoss coaxial feed-line that has a characteristicimpedance of 50Ω,to match the transceiver input impedance.Coupling the antenna tothe transceiver via feed-lines having an impedance other than 50*reduces the efficiencyof the antenna system and can cause interference to nearby broadcast television receivers,radio receivers,and other electronic equipment. NOTE:Transmitting without first connecting an antenna or other matched load may damagethe transceiver.Always connect the antenna tothe transceiver before transmitting. All fixed stations should be equipped with a lightning arrester to reduce the risk of fire,electric shock,and transceiver damage. The possible locations of antenna on a car are shown as following: 08 09 Accessories Connections External Speaker ■ If you plan to use an external speaker,choose a speaker with an impedance of 8Ω.Theexternal speaker jack accepts a 3.5 mm(1/8")mono (2-conductor)plug. NOTE:External speaker adopt double port BTL,please care about the connecting way.The speaker can not connect with the ground,otherwise the speaker will be fault.Thewrong connecting way as the follow- ing picture. Microphone ■ For voice communications,connect a microphone equipped with an 8-pin modular pluginto the modular socket on the front of the main unit.Press firmyly on the plug until thelocking tab clicks.At- tachthe supplied microphone hanger in an appropriate location usingthe screws included in the screw set.

Quanzhou RadioBoss Technology Co., Ltd No.8, Chuangzao Road, Optoelectronics-information industry base, Nan’an, Quanzhou, Fujian Date: 2026-06-26 Declaration Letter FEDERAL COMMUNICATIONS COMMISSION Authorization and Evaluation Division 7435 Oakland Mills Road Columbia, MD 21046 Subject: Declaration of compliance to the requirements of §15.121 FCC ID: 2BLTR-TH2000 Dear Sir/Madam, We declare that, this scanning receiver is incapable of operating (tuning), or readily being altered by the users to operate, within the frequency bands allocated to the Cellular Radiotelephone Service in part 22 of this chapter (cellular telephone bands). This device will not be able to receive transmissions in the cellular telephone bands by means of clipping the leads of, or installing, a simple component such as a diode, resistor or jumper wire; replacing a plug-in semiconductor chip; or programming a semiconductor chip using special access codes or an external device, such as a personal computer. This device is also incapable of converting digital cellular communication transmissions to analog voice audio. This device is designed so that the tuning, control and filtering circuitry is inaccessible. Any attempts to modify the equipment to receive transmissions from the Cellular Radiotelephone Service will render the receiver inoperable. This scanning receiver rejects any signals from the Cellular Radiotelephone Service frequency bands that are 38 dB or lower based upon a 12 dB SINAD measurement. We are aware that the modification of this device to receive transmissions from Cellular Radiotelephone Service frequency bands will be considered to constitute manufacture of such equipment. This includes any individual, individuals, entity or organization that modifies one or more scanners. Any modification to receive transmissions from the Cellular Radiotelephone Service frequency bands voids the certification of the scanning receiver, regardless of the date of manufacture of the original unit. Sincerely Yours, Signature: ___________________________ Contact Person: Sophia Wong
