PASSWORD

Use passwords to restrict access to the modification of 

certain parameters using the SETPOINT, PROGRAM, 

or OPTIONS menu keys. Each parameter is associated 

with a level of access. Each level of access is associ-

ated with a specific password. The access levels avail-

able are Level 1 or Level 2. 

•  If a parameter is tagged as Level 1, password 9675 

must be entered in order to change the value.

•  If a parameter is tagged as Level 2, password 

9725 must be entered in order to change the val-

ue. Entering the Level 2 password also allow the 

changing of a Level 1 parameter.

•  The maine Rocke switch must be turned OFF in 

order to change any parameter in the OPTIONS 

key.

Pressing the SETPOINTS, PROGRAM, or OPTIONS 

key take the user to the Login Prompt. When the user 

is first presented with the Login Prompt, the password 

field is blank. If you need to change Level 1 or Level 2 

parameters, you must know the appropriate password. 

At that point only the parameters changeable under 

the specific password level is displayed. For example, 

if the user presses the OPTIONS menu key, and then 

enters a Level 1 password, the user is presented with 

a list of option parameters that are tagged as Level 1.
Press the correct sequence of numerical keys (the 0 key 

through the 9 key) to enter the password and press the 

 key. As digits are entered, asterisks are placed in the 

password field. Once entered, the menu system com-

pares the password to a list of stored passwords. If the 

entered password matches one of the stored passwords, 

the user can access at the specified level, and the dis-

play shows the first applicable parameter of the menu 

list, with the appropriate edit prompts. If the password 

is not correct, the screen displays “Password Incor-

rect” for two seconds and reverts to the Login Prompt. 

Pressing the 

 key during password entry cancels the 

password entry process and takes the user back to the 

Login Prompt.
