Step 3: Microphone and System Status
When the battery and lock sequences are complete, the microphone and system
status can be verified .
To check the microphone and system status, turn the program control to the desired
program position .
Adjust the volume and sensitivity controls each to the 12:00 position .
Observe the green LED indicator as you snap your fingers or speak loudly near the
microphone . The green light should illuminate with each snap of your fingers and
with each syllable .
If the green light still does not illuminate, try using the auxiliary microphone and repeat
the system check sequence steps 1-3, as just described . Successful verification of the
microphone and system status with the auxiliary microphone would indicate that the
headpiece needs to be replaced .
Note: The green LED will not light up when using a program with the AGC
disabled. Check with your programming center regarding which program
to use for assessing the microphone status.
Replacing Components
The three most common actions required to restore your processor to proper
functioning are: (1) changing the lithium ion battery, (2) replacing the cable, and
(3) replacing the headpiece, as described below .
Lithium Ion Rechargeable Battery
The PSP is powered by a custom-designed, rechargeable lithium ion battery . An
alternative battery compartment, accepting three AA (or LR06) batteries, can be
used with the processor .
As described in “Performing a System Check,” Step 1, a depleted or nearly depleted
rechargeable battery should be replaced with a fully-recharged battery by taking the
following actions .
To Change the Lithium Ion Rechargeable Battery:
• Turntheprogramcontroltotheoff(o)position.
• Removetheusedrechargeablebatterybygentlypressingandraisingthe
release lever on the left side of the processor, while at the same time sliding
the battery case toward the lever . Return the used rechargeable battery to
the charger, according to the instructions in the “Batteries and Battery Charger”
section found earlier in this user guide.

Performing a System Check
You 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 you
get used to the steps, it takes less than one minute to complete a system check .
Step 1: Check Battery Charge Status
Turn the processor program control to the off (o) position and then to the desired
program position , , or .
Next, observe the red LED indicator . The red LED light sequence will indicate the
battery charge status, as:
• 3-4quickblinksindicatethatthebatteryisfullycharged.
• 2quickblinksindicatethatthebatteryissufficientlychargedtopowerthesystem.
• 1quickblinkindicatesthatthebatterychargeisnearlydepleted.Thebattery
should be replaced .
Instructions on how to change the battery are provided later in this section .
Step 2: Check Lock Status
The term lock refers to the successful transmission of continuous signals between
the processor, cable, headpiece and the implant across the skin .
To check the lock status, continue to observe the LED indicator . After the fast blinking
battery test sequence, the red LED will continue to flash approximately once per second
if the headpiece is not in its proper position over the implant .
Adjust the position of the headpiece over the implant until the red LED stops
flashing (Note: If the audible alarm feature has been activated during programming,
the alarm will beep once each second until proper lock status is achieved . The
audible alarm feature is usually programmed to be active in young children who
typically do not report interruptions in sound transmission) .
When the headpiece is properly positioned over the implant, the red LED will stop
flashing . This signifies that the system is sending information correctly between the
headpiece and the implant . If lock cannot be established, replace the cable
or headpiece, as described later in this section . If the problem continues, contact
your audiologist .
