Using TTY
A TTY (also known as TDD or text telephone) is a
telecommunications device that allows people who are deaf
or hard of hearing, or who have speech or language
disabilities, to communicate by telephone.
Your Treo 700wx smartphone is compatible with select
TTY devices. You can connect a TTY/TDD machine to your
smartphone through the headset jack, but you cannot use
your headset jack with a headset or hands-free kit while
this mode is enabled. Please check with the manufacturer
of your TTY device for connectivity information and to
ensure that the TTY device supports digital wireless
transmission.
To use TTY, you may need to make additional
arrangements with Verizon Wireless. Please contact
Verizon Wireless’s customer service department for more
information.
1. Press Start and select Settings.
2. On the Personal tab, select Phone.
3. On the Phone tab, select the TTY/TDD list, and then
select either TTY Full, TTY + Talk, or TTY + Hear.
4. Press OK. A keyboard icon appears at the top of your
Today screen whenever TTY is enabled.
To disable TTY, repeat these steps and select Off in step 3.
FCC Hearing Aid Compatibility
Your Treo is compliant with the FCC Hearing Aid
Compatibility (HAC) requirements. For additional HAC

STATIC ELECTRICITY, ESD, AND YOUR PALM DEVICE
Electrostatic discharge (ESD) can cause damage to
electronic devices if discharged into the device, so you
should take steps to avoid such an occurrence.
Description of ESD
Static electricity is an electrical charge caused by the
buildup of excess electrons on the surface of a material. To
most people, static electricity and ESD are nothing more
than annoyances. For example, after walking over a carpet
while scuffing your feet, building up electrons on your
body, you may get a shock—the discharge event—when
you touch a metal doorknob. This little shock discharges
the built-up static electricity.
ESD-susceptible equipment
Even a small amount of ESD can harm circuitry, so when
working with electronic devices, take measures to help
protect your electronic devices, including your Palm
®
device, from ESD harm. While Palm has built protections
against ESD into its products, ESD unfortunately exists
and, unless neutralized, could build up to levels that could
harm your equipment. Any electronic device that contains
an external entry point for plugging in anything from cables
to docking stations is susceptible to entry of ESD. Devices
that you carry with you, such as your Palm device, build up
ESD in a unique way because the static electricity that may
have built up on your body is automatically passed to the
device. Then, when the device is connected to another
device such as a docking station, a discharge event can
occur.
Precautions against ESD
Make sure to discharge any built-up static electricity from
yourself and your electronic devices before touching an
electronic device or connecting one device to another. The
