THE START
When the
VoiceUSB
device is set to work, that is, SIM card inserted, antenna, phone, analog
phone line or PC (depending on needs) and power supply are connected, the Power LED is on and the
Status LED is blinking indicating, that the module is preparing for work. The initialization can take up
to 20 seconds (it is recommended to wait). During that time, the module checks the SIM card, detects
the appropriate GSM network and checks the operating parameters. When initialization is done, the
Status LED becomes constant.
Note:
If PIN code request is active on the SIM card, then Error LED starts
blinking and phone signal is busy. That means that the module is waiting for the PIN code.
