If in doubt, do not wear headphones while mobiling. •Do not transmit with high output power for extended periods; the transceiver may overheat. •Do not modify the transceiver unless instructed by this manual or other KENWOOD documentation. •Do not expose the transceiver to long periods of direct sunlight nor place it close to heating appliances. •Do not place the transceiver in excessively dusty, humid or wet areas, nor on unstable surfaces. •If an abnormal odor or smoke is detected coming from the transceiver, turn OFF the power immediately. Contact a KENWOOD service station or your dealer. •This transceiver is designed for a 13.8 V power source. Never use a 24 V battery to power the transceiver. NOTICES TO THE USER One or more of the following statements may be applicable: FCC WARNING This equipment generates or uses radio frequency energy. Changes or modifications to this equipment may cause harmful interference unless the modifications are expressly approved in the instruction manual. The user could lose the authority to operate this equipment if an unauthorized change or modification is made. INFORMATION TO THE DIGITAL DEVICE USER REQUIRED BY THE FCC This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can generate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that the interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: •Reorient or relocate the receiving antenna. •Increase the separation between the equipment and receiver. •Connect the equipment to an outlet on a circuit different from that to which the receiver is connected. •Consult the dealer for technical assistance. When condensation occurs inside the transceiver: Condensation may occur inside the transceiver when the room is warmed using a heater on a cold day or when the transceiver is quickly moved from a cold location to a warm location. When condensation occurs, the microcomputer and/or the transmit/receive circuits may become unstable, resulting in transceiver malfunction. If this happens, turn OFF the transceiver and wait for a while. When the condensed droplets disappear, the transceiver will function normally. ii CONTENTS SELECTING A FREQUENCY.................................. 15 VFO MODE.......................................................... 15 MHz MODE.......................................................... 16 DIRECT FREQUENCY ENTRY...................................... 16 CHAPTER5MENU SETUP WHAT IS A MENU?................................................. 18 MENU ACCESS...................................................... 18 MENU FUNCTION LIST.......................................... 19 CHAPTER 6OPERATING THROUGH REPEATERS OFFSET PROGRAMMING FLOW........................... 22 PROGRAMMING AN OFFSET................................ 23 SELECTING AN OFFSET DIRECTION.............................. 23 SELECTING AN OFFSET FREQUENCY............................ …

Letter of Attestation Model: TM-271A-1 Scanning receiver This letter attests to the fact that Kenwood scanner receiver model TM-271A-1 meets the requirements of the FCC Rules, 15.121(a). Compliance is achieved through the following method(s): (1). The Microprocessor is hard coded to not accept programming, selection, scanning or direct entry of Cellular band frequencies. (2). Filtering precludes reception of mixer images or harmonics of Cellular band frequencies. (3). Subminiature SMD assembly and inaccessible multiplayer PCB construction all but precludes attempts at circuit hardware modifications.

At first, bench tests were performed to locate the spurious emissions at the antenna terminals. 2. In the field, tests were conducted over the range shown, The test sample was set up on a wooden turntable above ground, and at a distance of three meters from the antenna connected tot he Spectrum Analyzer. 3. In order to obtain the maximum response at each frequency, the turntable was rotated, and the search antenna was raised and lowered. The EUT was also adjusted for maximum response. Tests were conducted in Horizontal & Vertical polarization modes. 4. The field strength was calculated from: E μV/m @ 3 m = Log 10 -1 (dBμV + A.F. + C.L.) 20 5. Measurement Results: Attached for "Worst Case" conditions. MFA p0380004, d0380073 FCC ID: ALH31251110 Page Number 7 of 12.
