The DT2000-Dual can indicate its current status through three pins. These three pins can be
connected to LEDs to more quickly and easily determine the status of the module. The SMS LED
indicates to the user if there is a SMS message or a voicemail message. If there is a SMS message or a
voicemail message, the SMS LED will turn on. After the user has read the SMS message or listened to the
voicemail message, the SMS LED turns off. Shortly after the module has been turned on, the Idle LED
should turn on indicating that the module is in-service. This means that the module is within the range of
the base station and is able to receive a signal from the base station. When the module is in traffic or
conversation stage, the Busy LED is on.
