follow the procedure below:
■ The operation is resumed automatically after recovery from power failure with the setting before power
failure.
1. Check the power switch is OFF. (MPR-S163-PE and MPR-S313-PE only)
2. Check that the battery switch of battery mounting box for power failure alarm (optional component) is
OFF if the battery mounting box for power failure alarm is installed.
3. Connect the power supply cord to the dedicated power source before putting samples in the chamber.
4. Turn on the power switch. (MPR-S163-PE and MPR-S313-PE only)
At the power on, the high temp. alarm is activated. The alarm indicator blinks and the blinking chamber
temperature is displayed.
■ At the start-up with the factory setting, the high temp. alarm is activated when the chamber temperature
is higher than 10 oC, therefore the high temp. alarm works (High temp. alarm; temperature display blinks,
alarm indicator blinks, buzzer sounds after 15 minutes)
5. Set the desired chamber temperature. (page 14)
■ The factory setting of chamber temperature is 5 oC.
<Important>
■When the power supply has been turn off, wait 5 minutes or more after recovery of power supply,
connect the power supply plug to the outlet (and turn on the power switch of the MPR-S163-PE or
MPR-S313-PE). The compressor requires 5 minutes to re-start.

● Cycle defrosting
The chamber temperature is kept stable by ON/OFF operation of the compressor. When the
compressor is OFF (stopped), the frost on the evaporator is melted by the heater. This defrosting never
influences to the chamber temperature.
● Defrosting by defrost sensor
The cycle defrosting may not be sufficient to remove the frost on the evaporator when the ambient
temperature is high, the door is opened frequently, or heavy moist items are stored in the chamber. In
this case, the defrosting operation is started automatically when the defrost sensor detects the frost.
During the defrosting, the current chamber temperature and dF is displayed alternately on the
