1. Introduction ► Scope:- Service Diagnostics Routines can use for XXL, Side by Side products with STEALTH user interface with single evaporator fan product. ► Objective:- This routine is capable of controlling the product Loads facilitating service. In some cases is also possible to inform the result of the current status of the load being tested.

2. Normal mode ► Service mode can be entered in Normal mode only (when cooling is ON). ► The following steps to be skipped for SN33, SN34, and SMX33 Step 5, Step 10, Step 12, step 14, Step 28, Step 30 Step 5, Step 10, Step 12, step 14, Step 28, Step 30 ► The following steps to be skipped for SN28, SL4 Step 5, Step 10, Step 12, step 14, Step 15, Step 19,Step 28, Step 29, Step 30 Step 5, Step 10, Step 12, step 14, Step 15, Step 19,Step 28, Step 29, Step 30 ► Door Ajar shall not be activated during service mode. ► Sleep mode is not allowed in Service mode. ► Cooling Off key combination is not allowed to toggle in service mode. ► Exiting service mode will produce DISENGAGE chime with Normal menu on UI.

3. Service Mode Access Method ► To enable Service Diagnostic Routine,Press and hold SW1 & SW2 for 3 second. 3 ->2->1 countdown will start on the UI,with single key press beep. 3 ->2->1 countdown will start on the UI,with single key press beep. ► During the 3, 2, 1 count down, If ice or water pad is pressed, it cancels the count down and no dispensing is permitted.”3” blinks 3 times with “invalid” chime 3 times, and user has to release pad and press Service mode key combination again to start it over. ► During the 3,2,1 count down, pressing any other key on UI or releasing Service mode key combination (before 3secs) cancels the count down and “3” blinks 3 times along with “INVALID” chime 3 times and user has to release all the pad which are pressing and start it over. ► Note: - The blinking and chimes are synchronized so that the moment 3 blinks, the chime shall be produced.

4. Service Mode ► Entering the service key combination shall activate the service mode as shown in above screen and produce ENGAGE chime.

5. Service Mode Navigation Method (Dual pad, Single pad/Non-Dispense) ► SW4 is used for step number decrement.SW5 is used for step number increment ► Holding down either button (SW4/SW5) for two seconds will cause the steps to decrement/increment steps numbers accordingly at the rate of 2 steps per second. ► If the Last Step is reached, Increasing the step shall return to the First Step ► If the First Step is reached, Decreasing the step shall return to the Last step ► SW3 key is used as the Change Setting Key. It is used to toggle the load which is tested therefore change the step setting information. ► If any other key / pad is pressed in service mode (except for the specified steps), the pad / key press will be ignored, no chimes shall be produced while pad / key is pressed..

6. ► For products with only 2 Digits available, in order to accomplish the 3 digits requirements in some steps, digits 1 and 2 will be displayed for two seconds, followed by digit 3 and a dash for two seconds (dash will signify the end of the number). For products with 3 Digits available the information shall be displayed using 3 digits. ► Only two digits needed to display production software version and six digits will be needed. This could be accomplished by cycling between digit pairs major revision, minor revision, and test revision. Each digit pair shall be displayed for 2 seconds on the 2 digits display information and shall have 1 second blank time in between each each sequence (test revision & major revision); ► The 2 digits and 3 digits display information shall never appear at the same time. When one is active the other shall be blanked; ► For each step, only the load(s) being tested on the Step shall be turned ON (case needed). Exiting each Step, the load(s) turned on in the Step shall be turned OFF
