Motorola C350 manual Using TTY Mode, Using Fixed Dialing, Using Dtmf Tones

Using TTY Mode

You can use an optional TTY device with your phone to send and receive calls. You must plug the TTY device into the phone’s headset jack and

set the phone to operate in one of three TTY

modes.

Notes:

•Use a TSB-121 compliant cable (provided by the TTY manufacturer) to connect the TTY device to your phone.

•Set the phone volume to level 4 (middle setting) for proper operation. If you experience a high number of incorrect characters, adjust the volume as necessary to minimize the error rate.

•For optimal performance, your phone should be at least 12 inches (30 centimeters) away from the TTY device. Placing the phone too close to the TTY device may cause high error rates.

Using Fixed Dialing

When you turn on fixed dialing, users can only call numbers stored in the fixed dial list. Use this feature to limit outgoing calls to a predefined list of numbers, country codes, area codes, or other

prefixes.

Turning Fixed Dial On or Off

	> Fixed Dial > On or Off

Using the Fixed Dial List

You must turn on fixed dialing to open the fixed dial list (see above)

Find the Feature M> Fixed Dial

You create and edit fixed dial entries just like phonebook entries. Fixed dial entries are stored on your SIM card, and do not have Type, Voice Name, or Ringer ID information.

Using DTMF Tones

You can send numbers to the network as dual tone multi-frequency(DTMF) tones during a call. Use DTMF tones to communicate with automated systems that require you to submit a PIN code or credit card number.

Press	To
M> Send Tones	send a number to the
	network as DTMF tones, for
	credit card calling or
	password entry

To set DTMF tones to be long, short, or off:

Find the Feature	M> Settings
	> Other Settings
	> Initial Setup > DTMF

Short sends a short fixed-duration tone for each keypress. Long sends each tone for as long as you depress the key. Short DTMF tones work with most automated systems.

Some systems (such as home answering machines) may require long tones for proper activation.
