2.5. Antenna Connection
The VoiceBlue Lite gateway has one SMA antenna connector for
all GSM modules, see Fig. 9. An external antenna cable is
connected to this connector. The external antenna should be
installed vertically on a place with a good GSM signal. For the
technical parameters of the antenna refer to Section 12.

Tighten the antenna connector gently with your hand, never use a
wrench!
2.6. Gateway Power Supply
• Be sure to use only the mains supply adapter that is included in
the gateway delivery.
• Before plugging in the gateway, make sure that the mains
voltage value meets the data given on the mains adapter label.
• Make sure that the antenna has been connected. If you connect
the gateway to the power supply without an antenna, the
GSM module transmitter might get damaged.
• Now plug the supply adapter into a wall socket and after it
connect the adapter connector to the gateway, see Fig. 10. The
status indicators indicate the proper operation. For their
meanings refer to Subs. 2.9.
