Ultratec's Compact/C portable TTY
This lightweight portable TTY is perfect for cell phone communication. Just connect the Compact/C to the digital cell phone, and you are ready to make/answer calls.
TTY-compatible wireless networks should be available nationwide. We encourage customers to check with their wireless network provider to learn more about the specific service capabilities in their area.
When you buy a cellular phone, make sure it meets the following criteria:
Not all digital cell phones have the ability to connect to a TTY. Look for the international TTY symbol on the phone's package or user manual to help identify phones that work with TTYs.
Wireless service providers vary by state and location, as well as by the capabilities they offer. To use a digital cell phone to make TTY calls, the service provider must support TTY tones. Check with your local service provider to see if they are TTY-compatible, and, if not, when they expect to become TTY compatible.
It's that easy!
The Compact/C. Look for the digital cell phone/TTY icon to identify TTYs that work with cell phones.
Ultratec's Compact/C is designed specifically for use with digital cellular phones. Other TTYs may not be compatible with digital cell phone technology, even if they include a 3.5mm jack to connect to other assistive devices. With its long battery life, light weight, and compact design, the Compact/C is the ideal portable TTY to use with cellular phones. In addition, the new Compact/C includes 32K of memory to store a directory of frequently called numbers and recall recent conversations.
Compact/Cs manufactured after May 2002 are automatically compatible with digital cellular phones. Older models of the Compact/C can be upgraded for $49. Contact Ultratec for details.
Older Compacts (non "/C" models) cannot be upgraded to be compatible with digital cell phones.
Unfortunately, we cannot upgrade Compacts previously modified by Audex for use with analog cell phones.
* Refer to the user manual for your cell phone because the phone will need to be "set up" properly in order to connect with a TTY. Since the same jack on the cell phone may used for handsfree operation as well as for TTY connection, and because the cell phone uses this jack differently for a TTY call, you must first set up your phone to make sure it works with the TTY properly. This is typically a menu item on the digital cell phone that needs to be selected.
Your service provider is the company that provides your wireless connection, for which you are billed, typically on a monthly basis. Wireless services vary by state and location. Contact your local service provider to find out if it supports TTY communication.
Knowing that digital compatibility should be coming in the future, Ultratec recommends customers purchase a digital cell phone with TTY Mode that includes both digital and analog capabilities, if the phone can be forced to operate in analog mode. If the phone is dual mode, then customers can use the phone in analog mode until the digital service becomes available.
