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:
• Turn the program control to the off (o) position.
• Remove the used rechargeable battery by gently pressing and raising the
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.
• Using another fully-charged lithium ion battery, align the slide track on the top
of the replacement battery with the slide track on the underside of the processor.
• Guide the battery onto the processor slide track and slide the battery until it
