The alarms that may be set by the user are 

HIGH TEMP ALARM 

LOW TEMP ALARM 

 

Setting security access code (optional) 

 

When delivered, the freezer has the password security value in the 
OFF setting.  This means that access to modes and settings other 
than RUN can be addressed.  

If you want to restrict access to all menus other than the RUN 
menu, which is a read-only menu, then you may activate the 
password security (PASSWRD SECURITY) by switching it to the 
ON setting. This setting resides in the CONFIGURE menu. 

Once you activate password security, you will automatically 
acquire the factory default password, which is a four-digit 

numerical code.  

Default access code:  1 2 3 4  

You may change the code itself by addressing the 

SETTINGS menu. 

Please note the two menus on the right, and remember that the 
choice of whether or not a code is needed is made in the 
CONFIGURE menu; but the code itself is edited in the SETTINGS 
menu. 

 

Setting security access ON of OFF 

 

1. Navigate to the CONFIGURE mode on the SYSTEM level menu, 

and then press ENTER. 

 

 

 

This will take you to the CONFIGURE menu. 

 

Scroll down to PASSWRD SECURITY OFF (the current status). 

 

2. Use the UP and DOWN keys to change from  

PASSWRD SECURITY OFF to 

PASSWRD SECURITY ON, 

And press ENTER. 

 

You have now activated password protection
