Platinum Series (PSP) Body-Worn Sound Processor
PSP Controls
Program Switch
The program switch has five positions: Off, P1, P2, P3, and Mic Test. There are three program positions (P1, P2, P3) containing three sound processing programs of your personalized settings programmed by your audiologist. The Off position turns the processor power off so no sound is transmitted to the implant system, and the battery does not drain down when the processor is not in use. The Microphone Test Position allows a caregiver to use the microphone test earphones plugged into the auxiliary jack to listen to through the implant recipient’s headpiece microphone. The implant recipient will not be able to hear when the dial is set to the microphone test position.
Volume
Sensitivity
The sensitivity control dial determines the quietest level of sound that will be picked up from the environment by the microphone. It is typically set at the 12:00 (straight up) position. Turning the knob to the right increases microphone sensitivity and turning it to the left decreases microphone sensitivity.
(Turning Left) Decreases the microphone sensitivity so that softer and more distant sounds are NOT picked up by the microphone. This may help in the presenceof background noise.
(Turning Right) Increases the microphone sensitivity so that softer and more distant sounds ARE picked up by the microphone.
Frequently Asked Questions
Q: How can I tell if the battery is charged?
A: When the sound processor program switch is turned from the off (o) position to positions · , ·· , or ··· , the red LED light will blink as follows: 3 to 4 quick red blinks indicates that the battery is fully charged, 2 quick red blinks indicates that the battery is sufficiently charged to power the system, and 1 quick red blink indicates that the battery charge is nearly depleted.
Q: How can I tell if the internal processor is communicating with the internal implant?
A: When the battery charge sequence is complete, the LED indicator begins to flash red approximately once per second. Red flashing will continue until the headpiece is properly positioned on the head and lock is obtained.
Q: How can I tell that the microphone is picking up sound?
A: When the battery and lock sequences are complete, the LED should illuminate (flash) green as you snap your fingers or say ba-ba-ba close to the headpiece microphone.
Q: What does it mean when I can hear the processor beeping?
A: This is an audible alarm that alerts you when the implant is not transmitting sound to the implant. For example, if the headpiece falls off or if the battery is nearly depleted and requires changing, the processor beeps and the LED will flash red. Not all users will have this feature activated. The audible alarm is something the user's programming audiologist can turn on during programming.
Q: What is the Auxiliary Jack for?
A: Used to connect external auditory input sources, such as FM systems. An interface cable may be required for connecting certain audio inputs. Never plug a device that is powered through a wall socket directly into the speech processor.
Steps for Putting the Processor On and Completing a Device Check:
- Verify Processor is off.
- Check that PSP Rechargeable Battery or the AA Battery Pack is properly attached to the processor.
- Turn Volume Control all the way down.
- Set sensitivity to user setting (usually between 11:00 and 12:00).
- Place Headpiece over Implant.
- Turn Processor to appropriate program.
- Use LED to verify battery charge and lock status.
- Gradually increase the Volume Control to user setting.
- Check the microphone status by snapping your fingers or saying ba-ba-ba in a loud voice near the microphone. The LED should illuminate green while doing this.
- Perform a behavioral listening check. For example, ask the child to detect or discriminate the Ling Six sounds.
