LOCK function
The EM91465 series provide the LOCK function to inhibit toll dialing operation. Connecting a resistor on COL1
pin to VSS can select different LOCK control method that is conventional key lock or password lock. Also the
lock number that can be selected by connecting the resistors on COL2 or COL3 pin. After power on reset, the
password is fixed to 000 automatically. The lock function is disabled when the password is equal to 000 .
How to setup password
• Set LOCK function to password control mode. (Connects a resistor on COL1 pin to VSS)
• Off hook (or turn on HF function)
• Push : # , # , ops1 , ops2 , ops3 , nps1 , nps2 , nps3 , # . If the ops1~ops3 are the same with current password,
then nps1~nps3 will be stored in the dialer to replace current password. Otherwise, the current password can
not be updated. All the numbers pressed in the password setup procedure can not be dialed out when current
password is not equal to 000. If the current password are equal to 000, then only the first number “#” will be
dialed out.
Normal dialing :
Set lock function to none lock mode (without resistor connected to COL1 pin) or set password equal to 000.
In this case, the dialer is operated in normal mode and all functions work at unlimitation.
