SECTION 1 SAFETY PRECAUTIONS
______________________________________________________________________
1-3
THE USE OF ACCESSORY EQUIPMENT NOT COMPLYING WITH THE
EQUIVALENT SAFETY REQUIREMENTS OF THIS EQUIPMENT MAY LEAD TO A
REDUCED LEVEL OF SAFETY OF THE RESULTING SYSTEM. CONSIDERATION
RELATING TO THE CHOICE SHALL INCLUDE:
• USE OF THE ACCESSORY IN THE PATIENT VICINITY
• EVIDENCE THAT THE SAFETY CERTIFICATION OF THE ACCESSORY HAS
BEEN PERFORMED IN ACCORDANCE TO THE APPROPRIATE IEC 601-1
AND/OR IEC 601-1-1 HARMONIZED NATIONAL STANDARD.
REPLACE FUSES ONLY WITH ONE OF THE FOLLOWING PARTS:
Aspect P/N 430-0006, 1.25 Amps, 250V, 5x20mm
Littelfuse 217 Series, 1.25 Amps, 250V, 5x20mm
Wickmann 193 Series, 1.25 Amps, 250V, 5x20mm
ALWAYS REPLACE BOTH FUSES TOGETHER, EVEN IF ONLY ONE HAS FAILED.
1.2 CAUTIONS
Read this entire manual carefully before using the monitor in a clinical setting.
Do not autoclave the Digital Signal Converter or Monitor. Autoclaving will
seriously damage both components.
Do not block fan output. Keep at least three 3 inches of unobstructed space
between rear of instrument and wall and other instruments. Do not allow other
instruments to block airflow. Do not block ventilation inlet holes on the underside
of monitor.
Do not open Digital Signal Converter for any reason. The seal to prevent liquids
from entering the Digital Signal Converter may be damaged if opened. Service or
repairs must be performed only by qualified biomedical technicians.
Mixing of system configurations will increase sensor and hardware inventory
requirements and may create user and support issues.
Each BIS sensor type has its own placement method. Be sure to carefully follow
the appropriate package directions.
The A-2000 has been designed to operate with a disposable BIS Sensor. The
sensor is a silver/silver chloride electrode array that utilizes Aspect's patented
Zipprep technology and uses a proprietary connector. Use of other electrodes is
not recommended.
Continuous impedance checking may need to be disabled if the 1 nanoampere 128
Hz impedance check signal interferes with other equipment (e.g., evoked potential
monitors).
Check the battery periodically, by operating an A-2000 that has been disconnected
from the wall socket and that has been charging the battery for at least 4 hours.
After long periods of storage (e.g., more than 1 month) it may be necessary to
cycle (charge, then discharge) the battery a few times to get full charge capacity.
