Err and low battery indicator appears even with fresh batteries...

Lb (rather than L6) indicates a low battery. You need to replace the 9V battery in the carbon monoxide detector. The Err suggests an internal error but could just be due to the low battery.

If the Err persists after you replace the battery, press the peak level button (the right hand button) and check for an additional error code. If the Err message continues, replace the Night Hawk unit. If the unit is still under warranty, contact the manufacturer. Most of these units have a 10 year warranty. There are several models available from Kidde. The manual is available on the product site. For the KN-COPP-3 Night Hawk carbon monoxide detector, the documentation is available here: http://www.kidde.com/home-safety/en/us/products/fire-safety/co-alarms/kn-copp-3/ . Click on the Documents tab. The manual for the KN-COPP-3 999-0100 is here: http://www.utcccs-cdn.com/hvac/docs/2001/Public/06/User_Guide_KN-COPP-3_900-0100.pdf .

I hope this helps.

1. "Feedback" might have been intermodulation with another RF frequency. Make sure to use Sennheiser's frequency finder, or something similar, to determine what TV channels are clear. If you're using more than one transmitter, make sure they're all using the same channel bank.
2. The low bat/on indicator should be on solid if battery is good; and flashing if the battery is low.

Hi,

The battery indicator will flash and/or the IC recorder will display the error ACCESS when the batteries are low. Install new, fully-charged batteries to resolve this issue.
NOTE: Be sure to install the type of batteries specified in the user manual.

This actually a really common problem among Canon point and shoot cameras. There are a couple of methods that have worked well for others.

1. Open the battery compartment and remove the batteries. Then take a regular wooden pencil and place the eraser end down onto the battery contacts. Rotate the pencil to remove any corrosion. Sometimes a lack of proper battery contact will result in the low battery indicator.

2. Take a toothpick and wedge the tip under the battery contact and break it off. This will put more pressure between battery and contacts.

You can also try installing 3rd party firmware at http://chdk.wikia.com/wiki/CHDK_in_Brief
This is a bit technical and will probably void your warranty, but might be worth the try.

I also have this problem. I put freshly recharged batteries in the DX3900 and the camera starts to turn on and reads the memory card (the green LED blinks) and then I notice that the in CAPTURE mode the lens does not extend out of the body housing. The top display shows a flashing low battery warning and after approx. 15 seconds, the camera shuts off with no function.

I have determined that the camera appears to have changed its low battery sense level as I have verified that the batteries are indeed fully charged by using a volt meter. If I have the camera in a warm environment, and do not have the LCD display on (removes a major power drain) the camera can be made to work for a short while. If I select the LCD to turn on, the extra drain seems to cause the camera's battery monitor to think that the battery voltage is too low and the camera shut down. I have yet to resolve this issue.

First make sure you are using fresh lithium batteries. These cameras indicate low batteries quite early on. Rechargeables even when freshly charged are marginal.

If the problem persists remove the batteries. Set the camera switch to the off position. Set the focus switch to manual. Wait at least a minute. Then replace the batteries and switch on again.

Operating with low batteries can confuse the firmware and it may be stuck in a low-battery loop. If this is the case this should reset the camera by allowing the electronics to power-down completely.

If this does not work you wiil have to contact pentax support.

Hello,
The batteries u r using for your camera are of very low rating or low ampere output, you should use atleast 2100mAhr rating batteries and you will be very much satisfied with the performance.

Some cameras have a bettery setting in the menu. You need to make sure this setting is set to the type of batteries you are using. Usually when you use akaline batteries and even if you put in fresh batteries but still get the low battery indication then your camera is set to rechargable (Ni-Mh). Ni-Mh has more power to it then alkaline so this is why you get the low indication.

In cases where the blinking low-battery icon appears indicating insufficient power, wait approximately 8 seconds until the LCD monitor display and the EVF become blank. Then switch to another power source or replace with fresh batteries.
