    I have several computers in my home office, none have any problems it's a farily new house, no electrical problems in over 3 years. All of the sudden, my Back-UPS ES 650 begins clicking on and off about every minute or so. Tech Support said to turn setting to low, didn't fix it. They've confirmed what I knew, the battery is still good, it keeps PC, monitor, speakers, router, etc running when unplugged from the wall. I don't know how else to keep the unit from constantly clicking over for no reason...nothing has changed in the environment electrically speaking.

I am a power quality engineer and I loath APC quality.

NO CHANCE, the relay is an electrical "buffer"the grating noise is a motor/regulator/mechanism problem,take it somewhere else......if you have a trading standards office that you would like to visit......keep me informed.

Strange noise comes out from the ups after a power cut


The Back-UPS Office unit has five different tones or alarms:

1. Four beeps every 30 seconds (On Battery LED will be illuminated)
This alarm indicates that the Battery Power Supplied outlets are now supplying battery power as opposed to power from the utility. If the UPS determines that the input utility power is unsafe for your computer equipment, the UPS will switch to battery power.
Note: If the power disturbance is brief, you may only hear one or two beeps.

2. Continuous Beeping (On Battery LED will be illuminated)
This alarm indicates that a Low Battery condition has been reached and that the UPS will soon shutdown. Once the UPS transfers to On Battery operation, it can only stay on battery for a limited amount of time. The UPS will sound this alarm about two minutes before the batteries are totally exhausted. Once exhausted, the UPS will shutdown and turn off its output power to your equipment. If you hear this tone you should immediately shutdown your computer to prevent data loss or corruption.

3. Continuous Beeps for 30 seconds (Back UPS OFFICE 250 and 280 ONLY)
This alarm indicates the unit has detected an Overload condition after it has performed a self-test during start-up.

4. Continuous Two-Tone Beep
This alarm indicates a severe Overload was detected while the unit was on-battery operation. This tone will continue to sound until the unit shuts down.

5. Continuous Tone (On Battery LED will be flashing)
This alarm indicates that the battery-powered outlets are overloaded.

6. Continuous Tone (On Line and On Battery LEDs flashing) Back UPS OFFICE 350, 400, and 500 ONLY
This alarm indicates that an internal UPS fault has occurred.

Background noise similiar to a flurscent light bulb. How do I get rid of it?


A common problem is background noise if you did any of these silly things:
1. Keep handsets away from microwave ovens, computers, remote control toys, wireless microphones, alarm systems, intercoms, room monitors, flurscent lights, or electrical appliances.
2, You have to move to a different location of your house & I bet ya it decreases the background noise.
3. Remember its a cordless phone and needs clear signal to and from answering machine because thats what is connect to the phone jack.
4. Try switching phone jacks.
5. I had similar problem but it was will all phones and found the telephone repair guy had crossed a neighbor's newly installed line with my line at the terminal by the street. Boy was I fuming mad.

Getting false alarm from laser. Laser alarm keeps


If the laser continuously falses even with the car's ignition turned off, then your radar detector has an internal electronics problem. If your radar detector frequently or nearly continuously falses for laser while you are driving even in the middle of nowhere, then most likely the cause of the problem is either poor power and ground connections or electrical noise within your vehicle's electrical system. Jump over to radardetector.net for help in resolving these issues.

Clicking noise on all handsets upon pick-up


could there be interference ?

Severe noise interference.
• Keep the handset away from microwave ovens, computers, remote control toys, wireless
microphones, alarm systems, intercoms, room monitors, fluorescent lights, and electrical
appliances.
• Move to another location or turn off the source of interference.

Or maybe the unit is recording the calls, this is accompanied by an alert tone or click.
