NOKIA 2160 Cellular Telephone
(170-1227)                 Touch Tones                Faxback Doc. # 48781

Your phone is a "Touch Tone" phone, meaning that it creates certain sounds
when you press the keys.  These sounds can be used for many automated,
over-the-phone services such as checking your bank balance, using your
voice mailbox options, and even checking airplane arrival and departure
times.

Touch Tones are called "DTMF" (Dual Tone Multi-frequency) tones in the
phone.

Sending Individual Touch Tones

[Press keys during call.]

Touch tones can be used only when a call is active.  You would use the
Individual Touch Tone feature when, for example, you are prompted to
"press 1 and then the star (*) button".  You would simply press 1 *.

Note:  Individual Touch Tones can be sent only if Menu 4 3 is not set to
       Off.  Menu 4 3 is described in this section.

Sending Strings of Touch Tones

[During a call, with the display empty:

- > Recall from memory the string you want to send.

- > left [-] (Menu) then [SND].]

You can transmit Touch Tones one by one by pressing the keypad during a
call.  Additionally, you can store a whole digit sequence in a memory
location and send it as Touch Tones.  You could use this for frequently
used strings of numbers, such as your bank account number.

The phone sends (as Touch Tones) the digits that are currently on the
display.  You may also press and hold left [-] (Menu) then press \/ to
Send DTMF then left [-] (OK) then left [-] (Quit) to send a string of
Touch Tones.

To store a Touch Tone string

[Store Touch Tone strings the same way as you store phone numbers.]

For example, you could store your bank account number in the personal
directory.

To store Touch Tone strings with a phone number

- > Key in the phone number.

- > press *** (p) or **** (w).

- > key in the Touch Tone string.

- > store the number in the normal way.

*** creates a "p" (pause) character.  When you recall this number sequence
from memory and press [SND], the phone dials the phone number, pauses 2.5
seconds, then sends the DTMF digits.  You can add as many "p" characters
as you need.

**** creates a "w" (wait) character.  When you recall this number sequence
from memory and press [SND], the phone dials the phone number, then waits
for you to press the left [-] (DTMF).  This is handy if you are calling a
number that then prompts you to enter information, such as your bank
account number.

To link a stored phone number to DTMF digits in another memory location

- > Key in the phone number.

- > press ** (+).

- > key in memory location storing the DTMF string.

- > store the number in the normal way.

Use this if the phone number and DTMF digits do not fit in one storage
location; it links the phone number to the memory location storing the
DTMF string.

** creates a "+" (link to another memory location).  When you recall this
number sequence from memory and press [SND], the phone dials the phone
number, displays digits stored in the memory location you have entered,
then sends them as Touch Tones.

Entering only a "+" at the end of a stored number causes the phone to
prompt you for a memory location after the call is connected.  The phone
expects a memory location after the "+" character.  Enter a location
number and press left [-] (OK) to send the contents of that memory
location as Touch Tones.

Touch Tone Settings in the Phone

Your phone's Touch Tone settings are Menu 4 3, Manual DTMF Tones, and Menu
4 4, Auto DTMF Length.

Menu 4 3, Manual DTMF Tones

- > Left [-] (Menu) 4 3.

- > \/ to your choice.

- > left [-] (OK).

This determines the length of the individual Touch Tones when you press
keys during calls.  Note that regardless of this setting, strings of Touch
Tones can be sent.

Continuous means the tone sounds for as long as you hold the key.  Fixed
sets the tone length to 100 ms, regardless of how long you press the key.
Off turns the tones off, meaning that no tones are sent when you press
individual keys.

Menu 4 4, Auto DTMF Length

- > Left [-] (Menu) 4 4.

- > \/ to your choice.

- > left [-] (OK).

This determines the length of Touch Tones in strings.  Short sets the DTMF
tone length to 100 ms.  Long sets the DTMF tone length to 500 ms.
