Turns off, or fails to activate

This is a cordless Phone, which is fully charged, however, a few seconds after picking

it up (from its Stand) it switches itself off; Now, Both of these Handsets act in a

similar manner.

I have tried pressing 1,4,7 & Red key, service signs appears, then Shuts off.

Hi

I have the same problem, shut down during a call or during the dial process with a C530A duo.

Both handsets worked well for 3,5 years, now both give the problem.

I put in new batteries in both handsets, seemed to work ok, but now I have the same problems.

The battery indicator sometimes shows red, when testing the batteries out of the handset it shows they are full.

After putting the batteries back in the handset works for some time.

Any new ideas?

Hi, What is the state of the batteries when you put the phones back onto the base (charger?)? Does it show fully charged or does it show that is starts charging from a lower charge value. I'm just wondering if the batteries are failing and given that both sets of batteries may be the same age it may be just a coincidence that they are failing at the same time.

Replace one set of the NiMH batteries to see if it is the batteries that are the problem.

Sometimes they showed to be fully charged, other time, dead, but when tested, showed to be fully

charged. Have done the battery exchange, no difference.

Now, the screen illumintes for a short period, then Blanks.

The frustrating aspect, is the internitancy of the problem (typical of Electronic Problems); But most

frustrating, is loss of connection, during a call.

Oh, and these phones have had very little use.

Hi David,

Couple of things.

1. Have you checked whether turning Eco Mode or Eco Mode + off (if they are on) makes a difference.

2. Wondering if perhaps a 'firmware' check/update may be worthwhile. cannot find out if there are firmware updates available as the 'update server' information is stored in the phone and there is no link to it on the Gigaset website. Here is a link to the User Guide which shows how to connect to the LAN (internet) - select dynamic. (sorry if you know all this)

Once connected to the LAN here is how to update the firmware (if there is any available) http://www.manualslib.com/manual/877933/...

This is not a VoIP (needing firmware update), but bog standard (answere) phone set.

There is little that I can do, as the Screen blanks a few seconds after removing from the Cradle.

The Batteries are not the problem, as they measure about 1.5 volts off load, and 1.25-1.34 volts loaded test.

Hi, Maybe I was mistaken as I thought the link I provided showed both. Voip update and firmware update for your model phone.

There is no facility to connect the handset or Answere-phone base , to the internet; Unless there is something

I am missing. The system is not the A510 IP, just A510 A.

Had the same. Just to try if your rechargeable batteries need refreshment - replace them with regular ones and try to switch handset on. For me it worked.

Same things happend to my pair of Gigaset AS28H and I suspect it is some kind of planned obsolescence feature planted into the hardware. It seems like when the battery voltage drops to little less than 2.4v it shuts off. Given that the regular rechargeable batteries are rated at 1.2v this is pretty close.

Had the same experience, ordered Gigaset certified reloadable batteries at Gigaset support. They work fine for 3 weeks now. The Duracell rechargeable batteries I used before were not certified for use in the handset.. At a low tension (1,20v per battery) they do not deliver sufficient current for the handset and it seems the low battery circuit detect this low current and shuts down the unit. The certified batteries do deliver still sufficient current at low voltage. But I still have to see if my conclusions stay correct after several months of usage

Thanks for your answer.

I did put in new rechargeable batteries, in both handsets, some months ago, but the problem remains: sudden complete shutdown of the handsets during a conversation or during the dialling.

Now I put in non rechargeable batteries and for the moment I do not have the problem anymore.

Thanks for the hint, I wonder how long the batteries will last….

Works OK with non rechargeable batteries, but after 16 days of usage I had to put in new ones. So this was no real solution. It indicates however that around the 1,24V per battery, the handset suddenly shuts down.
