Important Notes
1. General Practice
Caution：
Important information is contained in any item and should be carefully read. Failure
to observe the instructions would result in damage to or malfunction of the
equipment.
Warning!
The warning message requires extremely careful operation of a certain step. Failure
to observe the instructions may result in serious personal injuries.
2. Safety
During operation, maintenance and repair of this instrument, the following basic safety measures
shall be observed. In case of failure to follow these measures or the warnings or notes indicated herein,
the basic protection provided by the instrument, its safety criteria of design and manufacture, and its
predicted use range would be impaired.
Hangzhou Bioer Technology Co., Ltd. would be irresponsible for any consequence resulted from
the user’s failure to observe the following requirements.
Caution:
This instrument is for indoor use.
a) The ground connection
To avoid the electric shock, the input power line must be reliably grounded. The instrument is
equipped with the three-pin plug that has the third pin (the pin connects the ground), therefore, the plug
shall be used with the grounded power socket only. This is a kind of safety device. If the plug cannot
be plugged into the power socket, please ask the electrician to install a correct power socket, so as to
make the grounded plug to work for safety.
b) Keeping apart from the live circuit
The operator shall not disassemble the instrument without permission. Only qualified
professionals are allowed to replace elements or adjust the machine inside. Replacement of elements
under energizing state is prohibited.
c) Be careful of the power supply
Before the instrument is connected with the AC power source, the voltage of the power source
shall be the same with the required voltage of the instrument (a deviation of 10% is allowed). The
rated load of the power socket shall not be lower than the requirements of the instrument.
d) Be careful of the power line
Usually, the instrument shall use the power line attached to it. If the power line is destroyed, it

Operation Manual for Oscillating Dry Bath Important Notes
—III —
must be replaced but not be repaired. The replacement shall be carried out with the power line of the
same type and same specification. No goods shall be put on the power line when the instrument is
working and please do not put it in a frequently-visited place.
e) The plugging in and removing of the power line
The user should hold the plug to remove the power line. When plugging in the plug, the user
should make sure that it has been fully plugged in; when removing the plug, do not pull the power line
forcefully.
f) Placement of the instrument
This instrument shall be fixed in a low RH and low dust place apart from water source (e.g. water
pool and water pipeline) and the room shall be well ventilated, and free of corrosive gas and
interference of strong magnetic field. The instrument shall not be placed in a wet or dusty location.
The openings on this instrument are for ventilation circulation and in order to avoid over-heat of
the instrument body, they shall not be blocked or covered. When a single set of instrument is used, the
interval between ventilation openings before and after the instrument and the nearest object shall not
be less than 25cm. Also, don’t use the instrument on loose or soft surface, or the air inlet at instrument
bottom might be blocked.
Excessive temperature would impair the test performance or result in fault of instrument. This
instrument shall not be used in location subjected to direct sunshine. The instrument shall be kept away
from hot gas, stove and all other heat sources.
If the instrument is to be set aside for a long time, the power plug shall be withdrawn and the
instrument covered with soft cloth or plastic film to avoid entrance of dust.
Caution:
In any of the following cases, immediately cut off the power supply, withdraw the
power plug from the power socket, and contact the supplier for treatment:
Liquid drops into the inside of the instrument;
The instrument is rained or watered;
The instrument works abnormally, especially generates abnormal sound or
odor;
The instrument is dropped or its casing is damaged;
The function of instrument obviously changes.
g) Warning sign
Warning!
There is a sign of “HOT SURFACE” on the instrument. The metal part (module)
near the sign shall not be touched with any part of the body when the instrument is
operating in a high temperature state or just finishes this operation to avoid scald!
3. Module Installation and Instrument Maintenance
The instrument module is not fixed by screws. At the time of installation, the bevel at the left

Operation Manual for Oscillating Dry Bath Important Notes
—IV —
bottom of the module should be tangent with the left bevel of the transition plate of the instrument;
press the right side down; if a buckle sound is heard, it means the module has been installed
successfully. At the time of disassembly, hold the module with the left hand and press the button on the
right of the module with the right hand, then the module will be separated from the mainframe.
The bore-hole of the instrument should be regularly cleaned with a wet swab to ensure the test
tube be well contacted with the wall of the bore-hole so as to have good heat conduction.
If the surface of the instrument is polluted, it can be cleaned with soft cloth which is soaked and
then squeezed.
Warning!
At the time of cleaning the surface of the instrument, the power supply must be
cut off;
The power supply must be cut off at the time of replacing the module;
Do not start the oscillating operation when the module is not installed;
The instrument surface shall not be cleaned with the corrosive cleaning agent.

8. Firmware upgrade
The oscillating dry bath adopts a U disk for firmware upgrade. First create a firmware directory in the
U disk, and then copy the upgrade program BYQ6614_cpu _****.bin to the directory, and rename
BYQ6614_cpu _****.bin as Firmware.bin. After the above operation, a firmware upgrade U disk for the
oscillating dry bath is made successfully.
Insert the firmware upgrade U disk into the USB interface of the instrument, press and hold the display,
and turn on the power to enter the upgrade mode. After clicking UPGRADE, the upgrade program in the U
disk will be read and the upgrade will start. When Upgrade Finish is displayed, it indicates the upgrade is a
