User Guide for the Platinum Series Sound Processor 29Performing a System CheckYou can verify your system’s operating status in three simple steps:Step 1) Check battery charge status.Step 2) Check lock status.Step 3) Check microphone and system status.To assure the system’s overall proper functioning, perform all three steps. Once youget used to the steps, it takes less than one minute to complete a system check.Step 1: Check Battery Charge StatusTurn the processor program control to the off (o) position and then to the desiredprogram position , , or .Next, observe the red LED indicator. The red LED light sequence will indicate thebattery charge status, as:• 3-4 quick blinks indicate that the battery is fully charged.• 2 quick blinks indicate that the battery is sufficiently charged to power the system.• 1 quick blink indicates that the battery charge is nearly depleted. The batteryshould be replaced.Instructions on how to change the battery are provided later in this section.Step 2: Check Lock StatusThe term lock refers to the successful transmission of continuous signals betweenthe processor, cable, headpiece and the implant across the skin.To check the lock status, continue to observe the LED indicator. After the fast blinkingbattery test sequence, the red LED will continue to flash approximately once per secondif the headpiece is not in its proper position over the implant.Adjust the position of the headpiece over the implant until the red LED stopsflashing (Note: If the audible alarm feature has been activated during programming,the alarm will beep once each second until proper lock status is achieved. Theaudible alarm feature is usually programmed to be active in young children whotypically do not report interruptions in sound transmission).When the headpiece is properly positioned over the implant, the red LED will stopflashing. This signifies that the system is sending information correctly between theheadpiece and the implant. If lock cannot be established, replace the cableor headpiece, as described later in this section. If the problem continues, contactyour audiologist.
