Figure 4-3) Installation and Removing the Belt Clip 8 4.3 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 5. Operating XR-2400 Radio 5.1 On/Off/Volume Control Turns the radio on and off and adjusts audio volume level. 5.2 PTT Button(Push-To-Talk Button) You can transmit by pressing PTT button. And then Red LED will be ON and your voice will be transmitted. 5.3 Channel Buttons(▼,▲) Channel Buttons(▼,▲) have 2 functions as shown in following. ① Channel buttons(▼,▲) are to change channels. ② Channel buttons(▼,▲) are to select menu at menu mode. 5.4 Accessory Connector The Accessory Connector is used when using an external speaker microphone or doing PC programming or making the Cloning or using as a Repeater. 9 5.5 RX /TX LED for Status This LED is a lamp indicating the current status of the Radio and please refer to the below contents. ① RX : Red Lamp ② TX : Green Lamp ③ CTCSS, DCS Error : Green Blinks. ④ Low Battery: Red Blinks With “beep” sound. 5.6. Charging the Battery 5.6.1 Safety Notes 1) The radio of XR-2400 series receives power from high-performance Li-ion battery (XSB-1800). XSB-1800 Battery is safe of high performance and highly reliable, and could be charged very fast. XSB-1800 Battery has been designed suitably only for the charger of DC-100. 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. 1) 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. 5.6.2 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. 10 Figure 5-1) Charging the Battery 5.6.3 How to Charge 1) Plug the DC-100 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. status LED indication status LED indication During charging Red LED lights. Detecting error Red LED is off. After charging Green LED lights. When charging Green LED lights 5.6.4 Charger (DC-100) The DC-100 charger is designed to charge only the Li-ion battery enclosed in this Radio. Figure 5-2) DC-100 Charger 11 Specifications of DC-100 Charger : • Adaptor Input Voltage : AC 100 ~ 240V • Adaptor Output Voltage : DC 5V • Battery : XSB-1800 • Quick Changing Tume : In3Hours and half • Operation Temperature : 0°C~+50°C • Size : 76(W)x85(D)x37(H)m/m • Charging Current : 750mA(Fast charging) 6.
