Therapy Connector Cable (W11)
A patient connector port used for delivery of either defibrillation or pacing therapeutic energies. The therapy connector allows
attachment of all available electrode accessories, including QUIK-COMBO pacing/defibrillation/ECG electrodes, and adult hard
paddles with energy select and discharge control.
NOTE: Some therapeutic accessories such as pediatric or posterior paddle attachments connect to the device by means of the
accessories mentioned previously.
The LIFEPAK 15 monitor/defibrillator uses varying jumper configurations within attached accessories to determine the type of
accessory connected. Discriminator circuitry within the A04 Therapy PCB defibrillator processor subsystem decodes the accessory
jumper configurations.
Speed Dial Assembly (W15)
A rotary, optical pulse-code modulator used to navigate through and select specific items from the LIFEPAK 15 monitor/defibrillator
menu system. Detent points on the SPEED DIAL provide tactile feedback to the user. When the desired item has been highlighted
on the display, the user presses the SPEED DIAL to enter the selection. The SPEED DIAL forms part of the user controls and
indicators block. Pulses derived from the W15 speed dial assembly pass serially to the user controls portion of A01 System PCB
ASIC.
Speaker Assembly (W17)
Used to annunciate device warnings, alarms, tones and, in AED mode, voice prompts. Drive for the W17 Speaker Assembly
originates in the A01 System PCB combined audio output block. Final amplification occurs in the A05 Interface PCB audio
amplifier.
SpO2 Connector Cable (W22)
A front panel connector port on the parameter bezel used for attaching an SpO2 (oximeter) sensor.
