activation/ voice deactivation for each line, this done as follows:

hear a BEEP now press then press , hang up and try the call again
and repeat again to get more sensitivity if needed.
Repeat for L2, L3 or L4 if desired.
To reduce the sensitivity level : select L1, you get dial tone, wait about 12 seconds
till you hear a double BEEP now press then press , hang up and
repeat again if needed.
Repeat for L2, L3 or L4 if desired
Special cases:
If audio activates suddenly in Default switch setting , your lines may be
“too Hot” Try ALT2 setting; if problem persists, try this one time programming:
Confirm switch is in Default , select L1, while dial tone is being heard, wait about
8 seconds till you hear a BEEP now press then You will get
confirmation via continues BEEPS and blinking audio. Hang up and repeat for L2,
L3 or L4 if needed. Keep the switch in Default.
If audio does not activate at all in Default setting even though you have
compatible phones your lines may be “too weak” try this one time programming:
Confirm switch is in Default , select L1, while dial tone is being heard, wait about
12 seconds till you hear a double BEEP now press then You will get
confirmation via continues BEEPS and blinking audio. Hang up and repeat for L2,
L3 or L4 if needed. Keep the switch in Default.
This device can be programmed to activate compatible corded phones via just Hold
