3. Product operation rules
The TRF-545W series has two different displays , one on the door and one in a freezer.
IPowered on for the first time
When the refrigerator is powered on for the first time, refrigerating chamber shall run when the temperature of
refrigerating chamber and freezer chamber is set as 5℃ and at - 18℃, respectively.
Operation of the temperature of display panel key
Regulation of refrigerating chamber
In the unlocking state, press and hold the “temperature regulation” key for 3 seconds, after the icon of the
temperature zone is switched to that of the refrigerating chamber, press the “temperature regulation” key to
regulate the temperature of the refrigerating chamber. After that, press the “temperature regulation” key once,
the temperature will drop by 1℃, and the gear of refrigerating chamber will cycle among “08” – “07” – “06”
– “05” – “04” – “03” – “02” – “OF” – “08”. Select the appropriate temperature, stop the key operation
and wait for 5 seconds, then the setting of the temperature gear is confirmed.
3.1 the display on the door

Regulation of the temperature of freezer chamber
In the unlocking state, press and hold the “temperature regulation” key for 3 seconds, after the icon of the temperature zone is
switched to that of the freezer chamber, press the “temperature regulation” key to regulate the temperature of the freezer. Then
press the “temperature regulation” key once, the temperature will drop by 1℃, and the gear of the freezer chamber will cycle
among “- 15” – “- 16” – “- 17” – “- 18” – “- 19” – “- 20” – “- 21” - “- 22” – “- 15”. Select the appropriate
temperature, stop the key operation and wait for 5 seconds, then the setting of the temperature gear is confirmed.
Quick cooling
In the unlocking state, press the “function” key repeatedly until the “quick cooling” icon flashes, stop pressing the key and wait
for 5 seconds, then the refrigerating chamber will enter the quick cooling function. The quick cooling function can be exited
manually by the same operation. The quick cooling mode will be exited automatically 2 hours later from entering quick cooling.
When the "quick cooling" function is on, the temperature control of the refrigerating chamber is set at 2℃ until the function exits. (in
the quick cooling state, the refrigerating chamber will automatically exit the quick cooling function by regulating the set temperature.
Under the quick cooling state, the quick cooling function will be exited automatically when the refrigerating door is opened for more
than 3 minutes.)
Quick freezing
In the unlocking state, press the “temperature” key repeatedly until the “quick freezing” icon flashes, stop pressing the key and
wait for 5 seconds, then the refrigerator will enter the quick-freezing function. The quick-freezing function can be exited manually by
the same operation. The quick-freezing function will be exited automatically 4 hours later from entering high cooling mode. When
the “quick freezing” function is on, the temperature will display - 24℃ until the function exits. (in the quick-freezing state, the
freezer chamber will automatically exit the quick-freezing function by regulating the set temperature. Under the quick-freezing state,
the quick-freezing function will be automatically exited when the freezing door is opened for more than 3 minutes.)
Smart
In the unlocking state, press the “function” key repeatedly until the “smart” icon flashes, stop pressing the key and wait for 5
seconds, then the refrigerator will enter the smart function. The smart function will be exited manually by the same operation. When
the “smart” function is on, the refrigerator can detect the state of each chamber by itself to run in the most efficient way. Under
the smart state, the refrigerator may automatically enter the quick cooling function or quick-freezing function according to the
temperature rise of the refrigerating and freezer chambers (under the smart function, when setting other functions, the smart
function may be automatically exited.)

Child lock
In the unlocking state, enter the “child lock” function: automatic startup: there is no key for this operation on the display panel, 30
seconds later, the child lock function will be automatically started, the “child lock” icon will be on, and the keyboard locked; exit the child
lock: when the “child lock” icon is on, press and hold the “child lock” key for 3 seconds to unlock.
Refrigeration off
In the unlocking state, press and hold the “temperature regulation” key for 3 seconds, after the icon of the temperature zone is switched
to that of the refrigerating chamber, press the “temperature regulation” key to regulate the temperature of the refrigerating chamber.
After the gear of refrigerating chamber is selected to “OF”, stop pressing the key and wait for 5 seconds, then enter the refrigeration off
function. When the set temperature of refrigerating chamber is set to “OF”, the refrigeration function is shut down. (in the refrigeration
off state, when setting other functions, the refrigerator may automatically exit the refrigeration off function. Note: please take out the food
in the refrigerating chamber before the cold refrigeration off function is started. ）When the “cold refrigeration off” function is on, the
refrigerating chamber enters the closed state.
Power off memory
When power goes off, the instantaneous working state at the time of power off will be locked. After power on, it will still work according to
the setting before power off.
Over temperature warning of freezer chamber
When the power is switched on, the temperature of the freezer chamber is higher than -12℃, the schematic box corresponding to the
temperature zone of the freezer chamber is on, and the digital zone flashes. Press any key to display the temperature of the freezer
chamber when it is powered on, press the key again or 10s later, it will return to the normal display state.

3.2 the display in the refrigerating room
First time to electricity
For the initial power on, the refrigerator should operate in accordance with the
middle 2 for the freezing chamber and middle 2 for the chilling chamber.
The function of adjusting the temperature manually.
Temperature adjustment in cooling room
Repeatedly press the button of " zone" until the indicator at the temperature zone of
refrigeration is on, press the button of "temp" to conduct the temperature
adjustment for the refrigerator. The grades for the refrigerator are cycling between
"strong" - "middle 1" - "middle 2"- "weak" -"power cool" - "vacation" - "strong".
Temperature adjustment of freezer compartment
Repeatedly press the button of "Zone" until the indicator at the temperature zone of
freezing is on,press the button of "Temp" to conduct the temperature adjustment for
the freezing chamber. The grades for the freezing chamber are cycling between
"strong" - "middle 1" - "middle 2" - "weak"- "power freeze" - "strong".
Quick refrigerating function
Under the status with the indicator at the temperature zone of refrigeration being on,
repeatedly press the button of "Temp" until the "power cool" function indicator is on,
and then enter the power cool function for the refrigerator. After you enter the
"power cool" for 2 hours,you will automatically exit the quick-cooling function.
After you exit the quick-cooling function, the set temperature inside the refrigerator
will automatically return to middle 2 .
Under the status of the quick-cooling function being on, after the time of opening for
the refrigerating door is over 3 minutes, it will automatically exit power cool function.

Quick freezing function
Under the status with the indictor at the temperature zone of freezing being on, repeatedly press
the button of "Temp" until the "power freeze" function indicator is on, and then enter the
quick-freezing function for the freezing chamber. After the refrigerator enters the "power freeze",
it will enter the status of strong cooling, and will automatically exit after 4 hours. After you exit the
quick-freezing function, the set temperature inside the freezing chamber will automatically return to
middle 2 . Under the status of the fast freezer function being on, after the time of opening for the
freezer door is over 3 minutes ,it will automatically exit power fast freezer.
Vacation function
Under the status of the indicator at the temperature zone of refrigeration being on, repeatedly press
the button of "Temp" until the "vacation" function indicator is on, after the "vacation” indicator is on,
it will enter the vacation function.
(Note: under the status of the "vacation" function being open, the refrigerator will enter the off
status; Before the initiation of the vacation function, please take out the food in the refrigerator.)
Power-off memory
When the power is cut off, the instantaneous working state of blackout will be locked and resume the
state after power on.
