brightness. Press the SET key to confirm. After setting, briefly press the REMOVE key to exit this setting.
Warning: If you press and hold the REMOVE key for 3 seconds or more, all incoming numbers, outgoing
numbers, and numbers stored in the blacklist will be deleted, and will display NO CODE when finished.
3. Checking incoming phone numbers
Press the “<” or ”>” keys for up-page and down-page checking of incoming calls. The LCD will display the
incoming numbers, time and date. It will display NO CODE if there are no incoming calls registered.

digits. It will display NO CODE if there are no outgoing calls.
5. REMOVE
When displaying an incoming, outgoing, or blacklist number, press the REMOVE key to delete the displaying
number. Warning: If you press and hold the REMOVE key for 3 seconds or more, all incoming numbers,
outgoing numbers, and numbers stored in the blacklist will be deleted, and will display NO CODE when
finished.
6. BLACKLIST
When checking the incoming or outgoing phone numbers, press BLACKLIST key on displaying number to
add into the blacklist. If successful, the display will display SAVE and SUCCEED. If the number was already
added to the blacklist, it will display REP.
If you wish to add a number that is not shown in the Caller ID, simply enter the number using the dialpad of the
telephone unit connected to the Blocker and press the BLACKLIST key.
Blacklist Operation: When a telephone number is in the Blacklist, the incoming calls will be blocked
automatically. The blocker device will pick up and then disconnect the call (go off hook) after 1 second. The
