Everytime I put batteries in it just beeps like the batteries are low and won't turn on

Most likely the memory batteries are low. According to the manual: Leave it plugged in and replace batteries located under the register tape cover. Should solve the problem.

MINE IS DOING THE EXACT SAME THING. ALL I DID WAS TAKE BATTERY OUT AND PUT BACK IN. NOW A BEEP AND ALL 5 LIGHTS FLASH. LET ME KNOW IF YOU SOLVED THIS !!

The troubleshooting instructions (link here)

will tell you that you will get a series of quick beeps when the batteries are installed correctly and making good contact.Conversely, the low battery indicator light on the power board will be lit when the batteries need replacement. Kwikset recommends that you use four quality alkaline AA batteries.
Also, Kwikset recommends that if your Powerbolt is beeping, that you take out the batteries and remove the powerstrip. Let it sit for one minute, then put the batteries back in and wait for another minute. If it does not beep, as in above for battery replacement, then the keypad needs to be replaced. If the unit beeps, then the powerboard needs to be replaced.
Is it at all possible that, when you replaced the batteries, you did not get the orientation correct for one or more of the batteries? Did you use new, brand-name alkaline batteries?
So, I've taken you through the steps that a Customer Service Rep is going to ask you before you make a call. If the problem still persists, then it's time to make that call. The number is 800 327-5625, Mon.-Sat. between 7:30-4:00. Pacific coast time. They should be able to assist you further with troubleshooting and parts.

Good luck-and please provide feedback if this helps!

Your batteries are too low.
When you switch on the camera, the lense go in. Then lense comes out fully. Then, if the batteries are low, lense goes in and camera turns off.
But if the batteries are too low, camera turns off before the lense retracts or even before the lense comes out fully.

These UPS systems do a self check everytime you press the power button. If the voltage in the battery is too low, you'll get a long drawn out beep. A new battery should solve that problem and it is even economical with a unit this size. Here's a link: http://batteryinternational.com/apc-backups-es-be350es-ups-battery-ups-batteries-f1.html

Simply remove the single phillips screw on the bottom of the unit and remove the battery cover. Replace battery and that's it. Very simple to do.

If you hear any beeps these can indictate where the fault is.

Beep codes Pc

More beep codes

Power up the pc and see if the fans are working.

charge the battery until light changes from red to green, then when you put the battery back into the camera make sure you push the battery all the way down until it locks in place. Hope this helps

Everytime I try to turn it on, the lens comes out for about a second, the camera beeps 3 times, the lens retracts and the camera shuts off. The battery is completely charged and the camera is only 4 months old. HELPP :(

Put your key in the on position hold down the reset button (i think it is the reset if not try the other ones) until you hear a beep. This resets the Perform Service so it won;t beep for another 3000.00 miles.

sounds like the non replaceable battery is bad get another headset cheap at www.n1wireless.com
