LEDs and buttons

There are two LEDs and a black button on the front of the Gigas- et M101 Data unit.

Both button functions

Setting a Basis to logon mode

Press the button on a powered base-type device for 10 seconds. The two LEDs blink in sequence, thus indicating that the device is in logon mode. Logon mode is automatically deactivated after successful logon or after 10 minutes: the blinking stops.

Resetting the device to the factory default

Press and hold down the button on the device that has been dis- connected from the mains. Connect the device to the power supply while holding the button down. LED 2 lights up after 10 seconds. This LED goes out in another 10 seconds indicating that the reset operation has been successful. The button can then be released.

LED 1: Gigaset M101 Data status

LED 1 indicates stand-by mode:

LED 1 blinks

The station is searching for the part-

 

ner or has not been registered.

LED 1 is constantly il- luminated

The partner was found, the transmis- sion route is on stand-by.

LED 2: data transfer

LED 2 indicates the status of the transmission route on the

V.24/RS232 interface:

LED 2 off

No data transfer

LED 2 flickers

Data transfer active
