1.Alarm test key (ALARM TEST): Test key for alarm device. By pressing this key, the alarm lamp is flashed, remote alarm is activated and buzzer sound. This means all alarm function operate correctly.

2.Buzzer stop key (BUZZER): To silence the audible alarm, press this key. The remote alarm is also silenced by pressing this key. (The buzzer cannot be stopped during remote alarm testing.)

3.Defrost key (DEF): By pressing this key for 5 seconds, the refrigerating operation is stopped. Pressing this key again after defrosting leads resumption of the operation.

Note: The refrigerating operation never resume automatically after defrosting.

4.Set key (SET): Temperature setting mode is led by pressing this key. Once the key is pressed, the changeable digit is flashed. Pressing this key again after setting desired temperature, the setting is stored into computer memory. If there is no key operation for 90 seconds during the temperature setting mode, the temperature setting mode is invalid automatically. See page 19 for the details.

5.Digit shift key ( ): Pressing this key in the setting mode causes the changeable digit to shift. Key lock is available by pressing this key for more than 5 seconds in the temperature display mode. Refer to page 20 for the key lock.

6.Numerical value shift key ( ): Pressing this key in the setting mode causes the numerical value to shift. “ON-OFF” of key lock can be selected by pressing this key in the key lock mode.

7.Alarm lamp (ALARM): This lamp is flashed when the audible alarm is activated.

8.Digital temperature indicator: This indicator shows the present chamber temperature or set temperature.

9.Compartment select key (TOP/BOTTOM) (MDF-U537D only): By pressing this key, internal temperature display of top compartment or bottom compartment and each setting is selected.

10.Top compartment lamp (TOP) (MDF-U537D only): This lamp lights when the top compartment is selected.

11.Bottom compartment lamp (BOTTOM) (MDF-U537D only): This lamp lights when the bottom compartment is selected.
