This manual contains important information about using Radio. 4.1 Installation and Removing the Antenna To install the antenna, insert the antenna into antenna connector and screw the antenna clockwise. To remove the antenna, screw the antenna counter clockwise. Figure 4-1) Installation and Removing the Antenna When installation of the antenna, giving a strong pressure to the Radio or pulling the antenna with a strong power from the Radio can make a damage on the antenna connector, which may cause the Radio to have a critical problem. 4.2 Installation and Removing the Battery 4.2.1 Installation of the battery To install battery, slide up the battery towards the top of the radio until battery latch is locked. 4.2.2 Removing the Battery - Slide the battery latch located on the bottom of radio to the open position as shown in Figure 4-2. - The battery is removed by pressing it against and sliding it towards the bottom of the radio 7 Figure 4-2) Installation and Removing the Battery 4.3 Installation and Removing the Belt Clip - To attach belt clip to radio, align belt clip rails with the grooves in radio and slide the belt clip onto the mounting rails until it latches into place. - To remove belt clip from radio, push up on tab of belt clip with flat bladed screwdriver and at the same time, slide the belt clip towards the top of Radio (Figure4-3). Figure 4-3) Installation and Removing the Belt Clip 4.4 Accessory connector Accessory connector is used to connect external speaker/Mic, and headset, etc. Please close the cover when nothing is connected. Figure 4-4) Accessory connector 8 5. Charging the Battery 5.1 Safety Notes 1) The radio of TJ-3100V/3400U series receives power from high-performance Li-ion battery (TJA-1800LI). TJA-1800LI Battery is safe of high performance and highly reliable, and could be charged very fast. TJA-1800LI Battery has been designed suitably only for the charger of TecNet. The charging of the enclosed Radio on the other maker’s charger will cause a damage on the battery and also, will cause a trouble on the Radio. 2) Please charge the battery before using the radio for best performance and safety. 3) When you charge the battery that is installed in the Radio, please turn off the radio first to charge the battery. The continuous rapid discharge (for example, when making a short circuit on the ‘+’ terminal of battery by a metal substance) may make a fatal defect and the battery can be exploded. Also, it can cause a fire. 4) Using the correct battery will improve the efficiency and safety. 5.2 The Time of Charging Low battery voltage will make the radio less coverage and also make the performance worse. Please charge the battery in case of following: ① When you think performance of the radio becomes lower ② When the red lamp on RX/TX Led blinks (every 0.5 second) during transmission or reception ③ When the battery icon blinks ④ When “beep” sound is generated while the radio is in use. 5.3 How to Charge 1) Plug the TJA-300L charger into the electricity power outlet. 2) When charging the Radio with the battery installed, please turn off the power of the Radio and place the Radio on the charger (The charger has a slide slot.). 3) After completion of the charging, the green LED on the charger will light. However, please continue the charging for 30 more minu…

April 25, 2012 Federal Communications Commission Equipment Authorization Branch 7435 Oakland Mills Road Columbia, MD 21046 Cover letter FCC ID : O99TJ-3100V Gentlemen: 1. TecNet International Inc. requires the Part 90 FCC grant list frequencies outside of Part 90 assignments because state and local government users specify operation outside of Part 90 so that they can interoperate with Federal agencies. The issue being that user’s that are not under NTIA frequency coordination must use radios that have FCC approval. 2. This FM transceiver that operated using frequency modulation(FM) incorporating traditional simplex transmission protocol (50%) duty and may be marketed to and used by employees for occupational operations, such as Federal and Public Safety agencies, e.g. police, fire and emergency medical, etc. 3. Maximum conducted power output according to 90.205(s) is 1.945 Watts. All qualified end-users of this device must have the knowledge to control their exposure conditions, and the exposure conditions of their passengers and bystanders, to comply with the General Population/Uncontrolled MPE limit and requirements. Users must be provided with antenna installation and transmitter operating conditions for satisfying RF exposure compliance. Sincerely, TecNet International Inc. 1420 N.W.

TecNet International Inc. 1420 N.W. Vivion Road Suite 109 Kansas City Missouri United States RF EXPOSURE EVULATION 1. Portable PTT devices The power thresholds and operating conditions in Table 1 are used to determine SAR test requirements for PTT radios required to comply with the general population exposure limit. When the occupational exposure limit applies, these power thresholds are increased by a factor of five (5) to determine the test requirements. SAR is required for PTT devices with maximum output power greater than these thresholds. 29 SAR evaluation is also required for separation distances smaller than those in Table 1. Contact the FCC Laboratory to determine if SAR evaluation is necessary for other frequencies or when the SAR is very low. Table 1 - SAR Evaluation Power Thresholds for PTT devices, f ≤ 0.5 GHz Exposure Conditions mW Held to face ≥ 2.5 cm 250 Body-worn ≥ 1.5 cm 200 Body-worn ≥ 1.0 cm 150 Notes: 1. The time-averaged output power, corresponding to the required PTT duty factor, is compared with these thresholds. 2. The closest distance between the user and the device or its antenna is used to determine the power thresholds. Results: Our PTT Transmitter Max Power is 1.945W Manufacturer declares RF Safety Distance of 2.5 cm ( 250*5*2 mW) /1.5cm (200*5*2 mW) for Occupational/Controlled Exposure which met the FCC Limits. Please refer to Users Manual for details of RF Exposure Information and Label Information.
