4.2 SAFETY PRECAUTIONS
There are areas where improper repair techniques will cause further damage. When the
instrument covers are removed, observe the following precautions and guidelines.
1. Power line voltages will be exposed; identify hazard points and avoid direct contact.
2. Battery terminals are accessible; do not short to each other or the positive terminal to
ground circuits, as the capacity of the battery is sufficient to create an over heating
safety hazard.
3. Fuses must not be by passed or replaced by different current, voltage or time delay
ratings.
4. The circuit boards contain static sensitive components; use proper static safeguard
techniques.
CAUTION: Li-lon batteries are intended for replacement by qualified service personnel only.
CAUTION: Li-lon batteries used in this device may present a risk of fire or chemical burn if
mistreated. Do not disassemble, heat above 100C (212F), or incinerate. Replace battery with
Datascope P/N: 0146-00-0069 only. Use of another battery may present a risk of fire or
explosion.
CAUTION: Dispose of used battery promptly. Keep away from children. Do not disassemble and
do not dispose of in fire.
4.3 GENERAL TROUBLESHOOTING GUIDELINES
This procedure does not cover all possible problems. The intent of troubleshooting is to
provide quick isolation and remedy of malfunctions and to return the instrument
promptly to safe patient care. A logical approach will quickly identify the problem and
suggest cost effective solutions.
Troubleshooting Tips
1. Isolate the cause of the problem to be either clinical, instrument or external.
If a clinical cause is suspected, take the physiological measurement by a manual method
or use an alternate measuring device. Check the physiological value against the instrument
specifications; if exceeds specification, continue with manual or alternate method.
If a problem with the instrument is suspected, first examine and / or replace patient
connected accessories. Check instrument set-up / configuration. Ensure the correct
battery charge profile is selected for the installed battery. If all set-ups are OK,
replace instrument with similar device.
If the environment is suspected, observe if the malfunction coincides with other
equipment cycling (especially high power motors, RF generators, etc...). Replace
problem instrument with an identical substitute. Place the problem instrument in a
low disturbance environment. If the problem persists in the low disturbance
environment, the instrument performance may be suspect. If the substitute instrument
exhibits similar poor performance in the original environment, the environmental
causes must be eliminated.
