<strong>KX</strong>-<strong>TDA100BX</strong> 9.1.2. Description of Each Part LED (BATALM): Lights when the lithium battery voltage drops below 2.8V. LED (SD ACCES): Lights on when the SD card is being accessed. SD card slot: Mounts the system program SD card. Reset Switch: Press to reset the system. System Initialize Switch: On default startup, set the switch to the "SYSTEM INITIALIZE" position before turning the power ON. Return the switch to the "NORMAL" position when the main power switch starts to flash. On normal startup, turn the power ON with this switch in the "NORMAL" position. USB connector: B-type connector. Used for PC programming. MOH 1, 2: External music on hold input. PAGING 1, 2: External PAGING output. Connect to a device with a built-in amplifier. 24
