Att CL2939 - all features requiring the battery is not working even after installing fresh batteries. Battery indicator still displays low battery. Cleaned battery contacts still experiencing same.

A simple circuit looks at the voltage that the alternator is producing, and turns thebattery light on if it is low. The battery light indicates a battery charging problem.

Is your battery door closing tightly enough to keep the contacts on the batteries touching the contacts inside the battery door? Make sure you have the batteries inserted correctly, too, matching + with + and - with -.

From what I just read on the Cobra website, you may be misinterpreting the battery indicator lights:

My radio keeps showing low batteries

This may simply be a matter of misinterpreting the low-battery indicator. We use two different types of battery indicators:

1. Battery Level Indicator: This battery indicator is always visible, and has several segments. When all the segments are lit, the batteries are full. When only the last segment is lit, the batteries are almost exhausted.
   
2. Low Battery Indicator: This type is usually NOT visible. It only appears when the batteries are low, at which time it flashes on the display to warn you of a low battery condition.

Please note that when you turn on your radio it first performs a display test. Everything on the display will light up for a few seconds, including the Low Battery Indicator. This does not mean that the batteries are low. After a few seconds the display test will end, at which time the Low Battery Indicator should go away.

Here is a link to the Manual for your radio:

It is a PDF file, which requires that you have Adobe Reader or equivalent installed on your computer for it to open and display properly. If you don't have it, it can be found here (it's free!):

Good luck!

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.

The MH120 comes with a battery case which opens up to reveal 6 AA batteries. Their is a battery indicator on the LCD display on the left. 5 bars is a full battery. 1 bar means it needs fresh batteries. It requires AA alkaline batteries. You can buy a NiMH battery pack as an accessory that uses rechargeable NiMH battery. This is available at extra cost from Uniden. It is accessory part number BP250.

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.

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.
