| Blocking Caller ID |

|
| appear to the person you call. |
|
| Using the Setup button: |
|
|
|
STEP 1 | Press the Setup button. | |
STEP 2 | Select Preferences. | |
STEP 3 | Choose Block Caller ID and press edit. | |
STEP 4 | Press y/n to choose yes (enable) or no (disable). | |
STEP 5 | Press ok. | |
STEP 6 | Press save. | |
|
|
|
|
| Using the star code: |
|
| Press *67 before dialing the number. (Caller ID blocking will remain enabled until |
|
| you enter *68.) |
|
| Blocking Anonymous Calls |
|
| Blocking anonymous calls prevents calls with unknown Caller ID from ringing your |
|
| phone. (For example, if a caller set his phone to not display Caller ID, the call is |
|
| considered anonymous.) These callers receive a busy signal or message. |
|
| Using the Setup button: |
|
| |
STEP 1 | Press the Setup button. | |
STEP 2 | Select Preferences. | |
STEP 3 | Choose Block Anonymous Call and press edit. | |
