the majority of the light emitted by CFLs is localized to the visible region of the spectrum (approximately 400-700 nm in wavelength). In addition, typical CFLs emit a small amount of UVB (280-315 nm), UVA (315-400 nm) and infrared (> 700 nm) radiation.
If a CFL were to exceed allowable levels of UV (according to IESNA RP 27.3), its packaging would be required to be labeled with a caution label. This standard, which was developed with the assistance of the FDA, requires lamp manufacturers to provide a suitable caution if one is needed. At typical use distances, UV levels from CFLs fall below the level of general concern for normal, healthy individuals and therefore carry no such warning.
the Check engine light (MIL) means, get it serviced
to a tech,vastly more.
check fluid levels, first. don't run it until oil levels are ok.
then fuses and scans it.
if PCM shows errors.we check those, carefully.
using tools'
got tools?gauges an meters?
bet no.
If printer is in warranty, demand for replacement.
1. Check ink levels in printer..if levels are showing, take out all ink cartridges refill them.
If levels are zero, go for new cartridges.
2. If ink level are showing in printer & physically cartridges having ink, then problem with print head, try to clean the clogged nozzles.
That is a subjective question. I would take the amplifier to my lab, connect 13.8 Volts DC then connect dummy loads, a scope, a signal generator, harmonic analizer , spectrum analyzer etc and then take it through its paces to be sure it meets puglished factory specifications.
You need to reinstall the S/W that came with the printer on your new computer. If you do not have the disc, you can go on line and download the driver and the S/W that detects and displays the ink levels. You would see the ink levels when go to print a document.
what I would do is find a mechanic with a gas analizer and find out what the levels of HC , CO & NOx levels are . by checking the levels of hc if real high then they know that there is alot of unburned fuel and then the CO would be low and this will cause black smoke . But there could be a chance that this is carbon build up coming out when under accel, the only way to have it checked properly so you dont waste anymore money is have some one with a gas analizer check it out and learning what the reasons are will take them right to the problem with the fuel system or ignition system o2's ect.
