The SHOUT 3G has a cellular micro- Subscriber Identification Module (SIM) card slot on the side
of the chassis next to the USB Micro-B port. For cellular services, the SHOUT 3G accepts any
cellular micro-SIM with services on a network that supports 2G Global System for Mobile
Communications (GSM)/GPRS and 3G Universal Mobile Telecommunications System (UMTS)/
High-Speed Downlink Packet Access (HSPA) services. A 4G LTE-only network will not support the
SHOUT 3G. NAL has validated SHOUT 3G operation on both AT&T and T-Mobile networks. Due
to network device requirements, the Verizon network is not supported. Request an account
that supports SMS service, packet switch data service, or both.

OUCHSCREEN
The SHOUT 3G has a resistive touchscreen. Use either a finger or a stylus to select options
displayed on the screen. Resistive touchscreens offer consistent and durable performance in
harsh environments. However, as with any touchscreen device, be careful not to damage it with
a sharp object. A plastic stylus with a rounded tip is recommended. Unlike a capacitive
touchscreen found on most cellular phones where a slight tap of the finger is required, a
resistive touchscreen requires more moderate finger pressure. Resistive touchscreens drift
slowly over time and need to be recalibrated periodically. To do this, open the

menu.
