How come the LED indicator of the modem terminal does not blink slowly? |
| |
|
| |
If the modem LED blinks slowly (i.e. 0.75sec on, 3 sec off), physical connection should be fine else check for SIM-Card's validity, SIM-Card holder and antenna should be in placed properly. Care should be taken when you mount the antenna in a clockwise direction. Do not force turn the connector of the terminal. Refer to modem hardware user guide for more details. |
