Service für Gigaset A540

Discharge should take place at room temperature. At temperatures below 0° C, the capacity of the batteries decreases considerably.
Charging should preferably take place in the range of 10 - 35°C, as this is where the batteries have the greatest capacity.
With NiMH batteries, the handset interrupts charging at temperatures above 45° C, with LiIon batteries below 5° C and above 40°-45° C, as the batteries must not be charged outside these temperatures.

NiZn (Nickel Zinc) batteries are not suitable for use in Gigaset handsets.

Recommented batteries:

For Gigaset handsets, use only the batteries approved by Gigaset. The high quality standard guarantees safe use and a long service life.
NiMh round cells type AAA can be purchased in our Gigaset online shop.

List of approved and recommended batteries:

It is practically impossible to determine the battery capacity or state of charge of a NiCd or NiMH battery by fast measurement. For the charge management of the Gigasets, it is only possible to recognize completely empty or completely full (just charged) batteries by the voltage. In most cases, however, the display will show 1/3 or 2/3 because the flat discharge curve, the temperature dependence of the voltage and the different battery types do not allow the charge level to be clearly identified.

If you operate your Gigaset on the telephone connection of a router/modem, make sure that you have noticed the following points:

• Use the phone cable from the Gigaset packaging.
• If the router or modem does not have a phone jack, it is necessary to use the enclosed phone cable or the enclosed phone adapter of your router/modem.
• Connect the cable to the router`s phone jack / phone port / FON port.
• Please check if your telephone data (internet telephone number, provider-profile, …) for the used telephone connection in the router/modem were entered correctly.
• Please make sure that your internet connection is working.

If the problem persists, please contact your provider.

By default, the number of the caller is shown in the display of your Gigaset telephone. You do not have to make any other settings on your Gigaset telephone. However, if the caller's number is not displayed, this can be due to the following:

- You have not ordered CID from your network provider or
- Your telephone is connected through a PBX that does not transmit all information.

Is your telephone connected through a PBX/gateway?
You can establish this by checking for an additional device connected between your telephone and house connection, e.g., a PBX, gateway etc.
In most cases, simply resetting this device will remedy the situation:
- Briefly disconnect the power plug of your PBX.
- Re-insert the plug and wait for the device to restart.

If the caller number is still not displayed:
Check the CID settings of your PBX and activate this function if necessary. In the user guide for the device, search for the term "CID" (or an alternative term such as "phone number transmission", "caller ID", ..).

If necessary, contact the device manufacturer. If this does not resolve the problem, it is possible that your network provider does not support the CID service for this number.

Have you ordered the CID service from your network provider?
Check whether your provider supports Caller ID (CID) and that the function has been activated for you. If necessary, contact your provider.
