Multitouch Support
The capacitive touch screen display affords enhanced capabilities for browsing web pages using

On-Screen Keyboard

keyboard.
Audio Feedback
Customized audio files can be loaded to add another dimension to the touch screen graphics
using personalized sounds, button feedback, and voice prompts.
Dual-Mode Wireless Connectivity
The TST-902 delivers high-performing wireless connectivity by employing a combination of
Crestron Extended (ER) Range 2.4 GHz RF and Wi-Fi® wireless technologies.
NOTE:Every TST-902 installation requires a Crestron ERwireless gateway to provide
essential wireless capability to the touch screen. The TST-902 will not function over Wi-Fi
communications alone.
lExtended Range RF(Required):Primary functionality is supported via Crestron ER
(Extended Range) wireless communications, providing seamless touch screen control with
true feedback. A single ER gateway provides dependable wireless performance at a range
of up to 200ft (60m) indoors.4,5 Roaming capability allows for even greater coverage
using up to eight ER gateways.
lWi-Fi Communications (Optional): Advanced wireless capabilities such as streaming video,
voice recognition, web browsing, and dynamic graphics are supported only by using both
ER and Wi-Fi communications together (dual-mode). Crestron-enhanced Wi-Fi wireless
performance supports up to 50ft (15m) of omnidirectional coverage indoors.5For Wi-Fi
networks with multiple access points, the TST-902 can hand off communication from one
access point to another if the active connection is lost.6Support for 802.11 b, g, and n
protocols affords reliable, high-speed wireless performance in virtually any RF
environment.
Instant-Waking Technology
The TST-902 has been engineered with Instant-Waking® technology, where the touch screen
display wakes instantly after being touched. Commands are also sent immediately, so
spontaneous actions like muting audio, pausing video, or changing a channel can be executed
without any waiting.
Extended Battery Life
The TST-902 features a large-capacity, user-replaceable Lithium Ion battery pack that allows for
up to nine hours of continuous operation and several days of typical use between charges.
Intelligent power management and Lithium Ion battery technology work together to provide a
lightweight, compact battery with long battery life.

Table Dock Charger
The TST-902 includes a table dock for charging its internal battery while simultaneously allowing
it to be used as a stationary tabletop touch screen. The table dock holds the TST-902 firmly at a
fixed upright angle while docked, and allows it to be taken off at any time for portable use. Its
sleek appearance makes it a perfect fit for any home or office.1
Wall Dock Accessory
The optional TST-902-DSW provides a flush mount, in-wall docking solution, allowing the
TST-902 to be used as a stationary wall mount touch screen that can be turned into a wireless
touch screen at any time.4
Notes:
1. The TST-902 ships with one TST-902-DS table dock included. Additional table docks, or the TST-902-DSW wall dock, may
be ordered separately.
2. Voice recognition, web browsing, weather information, Rava® SIPintercom, and certain other functions require an
internet connection via Wi-Fi® communications.
3. Voice recognition, streaming video, web browsing, and dynamic graphics capabilities require dual-mode wireless (ER and
Wi-Fi communications).
4. Item(s)sold separately.
5. Wireless range subject to site-specific conditions.
6. True roaming is supported for ER wireless communication only, affording uninterrupted wireless performance for
primary touch screen functions. Wi-Fi handoff capability enables automatic handoff between up to four predesignated
Wi-Fi wireless access points (WAPs). The last successful Wi-Fi connection is maintained indefinitely until that connection
is lost, at which point communication is handed off to the nearest available WAP. A very brief interruption to wireless
Ethernet communication may occur during the handoff. Primary ER wireless communication is unaffected by the Wi-Fi
handoff process.
7. ER (Extended Range) RF wireless communication supports basic wireless touch screen functionality, and is required for
all applications. For advanced functionality including streaming video, voice recognition, web browsing, and dynamic
graphics, Wi-Fi wireless communication is also required (dual-mode). The TST-902 will not work with Wi-Fi alone.

TST-902-BTP Features
The TST-902-BTP is a replacement Lithium Ion rechargeable battery pack for the TST-902
wireless touch screen. The user-replaceable battery pack allows for up to nine hours of
continuous operation and several days of typical use between charges. Intelligent power
management and Lithium Ion battery technology work together to provide a lightweight,
compact battery with long battery life.
NOTE:Lithium Ion batteries must be stored at 50%charge and cycled every three months.

TST-902-DS Features
The TST-902-DS is a stylish table dock designed for charging a single TST-902 wireless touch
screen while simultaneously allowing it to be used as a stationary tabletop touch screen. The
table dock holds the TST-902 firmly at a fixed upright angle while docked, and allows it to be
taken off at any time for portable use. Its sleek appearance makes it a perfect fit for any home
or office.
One table dock is included with the TST-902. Additional table docks can be purchased separately
to accommodate multiple docking locations.

Product Manual — Doc. 7750C TST-902 • 9
TST-902-DSW Features
The TST-902-DSW is an optional wall dock for the TST-902 wireless touch screen. Placing the
touch screen into the wall dock allows it to be used as a stationary touch screen while
simultaneously charging its internal battery.
When docked in the TST-902-DSW, the touch screen sits nearly flush with the outer bezel,
affording a clean appearance while preventing unauthorized removal. By entering a pass code or
pressing a button on the touch screen, the mechanism gently tilts the touch screen outward,
allowing it to be released for wireless use. A hardware key is included to release the touch screen
in the event of a power outage.
The TST-902-DSW is designed for flush-mount installation in a flat, vertical wall structure.1
Installation of the wall dock requires additional hardware (not included):
lThe TST-902-DSW-BB and TST-902-DSW-BBIback boxes are available for both framed
and masonry construction.
lThe TST-902-DSW-PMK,TST-902-DSW-WMKM, and TST-902-DSW-WMKT mounting
kits are available for preconstruction and postconstruction applications that do not
require a back box.
Note:
1. The TST-902-DSW docking mechanism works as intended when mounted in a standard vertical orientation (such as
within a wall). The maximum allowable tilt is 16° back. The mechanism will not eject properly at an angle greater than
this.
