Technical Data...76
Before using this equipment, please study this manual carefully and become familiar with the controls, display features and operating techniques. Inspect all components for damage. When connected to the hand held Host, the module configures the system to become a mains / battery operated portable vascular laboratory. This manual covers Doppler, Digital Photoplethysmography, Blood Pressure and Pulse Volume Recording (PVR) applications.
Introduction
1.0 Introduction
Specific applications are dependant on the module and include: Vascular Doppler

Introduction
1.1
Warnings Do not use this equipment in the presence of flammable gases. Do not use in a sterile field unless additional barrier precautions are taken. Do not immerse any part of the equipment in any liquid. Do not use solvent cleaner on any part of the system. Do not use high temperature sterilising or E-beam / gamma sterilisation processes. Do not attempt to use alternative universal power adaptors with the system. The universal power adaptor (part number ACC 105) supplied with the system, is the only one certified for use with the Dopplex® Assist range. If any doubt exists concerning the use of this equipment, an alternative method should be used.
CAUTION This product contains sensitive electronics, therefore strong radiated radio frequency signals (e.g. mobile phones) could possibly interfere with it. We recommend that the source of interference is identified and eliminated.
The use of mobile telecommunication equipment should be avoided during applications.
Do not destroy packing, either retain for future use or return to supplier.
Vascular, Doppler, Spectral, PPG, Diabetic and Venous Assist units are screening tools to aid the healthcare professional and should be used with clinical judgement before interventional procedures are undertaken. If there is doubt as to vascularity after using the unit, further investigations should be undertaken immediately using alternative techniques.
CAUTION Do not contact internal pins of the connectors in the modules and the patient simultaneously.
