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 XV-100A 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 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 minutes for the complete full charge. 9 status LED indication status LED indication During charging Red LED lights. Detecting error Red LED is off.…
