All gas detectors have an internal sensor that can be "poisoned" if you are not careful. They are especially sensitive to cleaning products that contain amonnia or aerosal spray cans. If these products are used in close proximity to the detector there is a good chance of permanently damaging the unit. The only recourse you have is to buy a new unit.

Hello, if your printer tells you need to replace the cartridges just press stop/cancel buton for at least 5 second and then you can use the printer only on black. I dont recomend you do that becouse your printhead might burnout.

My Kidde Nighthawk Carbon Monoxide detector was beeping shrilly and read gas. When pressed the reset button it read 221. Problem was it was sitting facedown in a box (i'd just taken it from my old...


A reading of 221 ppm carbon monoxide gas is a dangerous level that should be taken seriously. You could try a new battery and reset the detector. If in doubt, always err on the cautious side and have the apartment checked by a professional or by the local fire department.

A new carbon monoxide detector is a small investment that may prevent carbon monoxide poisoning or death.

Changed the battery. The alarm went off, tried to reset but will not work. When driving push on the brakes and the car shut down. Is this an alarm issue or an electrical engine issue. Don't know what to...


Yes this is an Alarm issue that's why your vehicle is shutting down as soon as you press on the brake pedal. Is this an aftermarket alarm or stock alarm? Sounds like aftermarket alarm to me and if it is, the way fix this issue is as soon as you put the red n black terminal on the battery and the alarm goes off press your alarm key right away to turn it off. If this doesn't work put your key on the ignition after you have installed the battery and just put it on the "ON" position engine OFF then click on your alarm remote once again.
