Fig. 5.3-31 Relation chart of password 2 protection status
In our factory default status, passwords are not provided excluding special products. Therefore, if the
password set for H198 or H99 is unknown or forgotten, we do not answer or inform you of the password
or its decoding method from protective status.
For this reason, set and control the password at your own risk. If a password is set at the delivery of the
product and its decoding is required, please contact the dealer you purchased or the unit manufacturer.
(We are not able to know the passwords set by customers.)
Setting and temporary disabling of password 1, 2 using multi-function keypad
Setting or temporary decoding of passwords 1 and 2 using the multi-function keypad is performed by the special
menu on the multi-function keypad. Therefore, function codes H99，H198 and H199 are not displayed on the
function code list of the function code setting menu or function code check menu on the multi-function keypad (H197
is displayed).
For the special password menu of the multi-function keypad, refer to the instruction manual of the multi-
function keypad.
