WARNING
lDo not use the device near medical equipment. The radio waves emitted by wireless
communication module could have an adverse effect on nearby pacemakers or electrical medical
devices.
lDo not use near automatic doors, alarms, or other automatic electrical control devices.
The wireless communication module could cause malfunctioning in these devices.
lDo not use any USB cables that have been damaged or deformed. Doing so could result in smoke,
overheating, or fire.
lCarefully read and correctly follow the instruction in this user’s manual about the use of USB
cables. Replace any cable that looks defective or damaged.
lDo not wash the device with water, or disassemble or tamper with it in any way.
Doing so could result in electric shock, fire, or smoke.
lWhen powering the device thru a USB connector, use a PC with a limited-energy circuit USB
output, or an AC adapter with a limited-energy circuit used to power PCs.
CAUTION
HANDLING OF PHOTO ABSORBANCE SENSOR
lThis device is for general analytic use. It was not designed for, nor should it be used for, medical
diagnostic purposes requiring very high levels of reliability and/or accuracy.
USHIO INC. cannot be held responsible for any damages or liabilities resulting from the
inappropriate use of this device for such purposes.
lTo avoid eye injury, never look directly at the light source in the device.
lWhen connecting and removing the USB cable, do so carefully; do not jam the connector or yank
the cord.
lAvoid dropping the unit or otherwise exposing to shocks or extreme forces.
HANDLING OF BATTERIES
lFollow all instructions of this manual on the handling and use of dry-cell batteries.
lUse only the battery type specified (AAA type). Other types may damage the unit.
lInsert batteries properly, matching the plus and minus ends to the equivalent connections inside
the unit.
lWhen replacing batteries, always replace all 3 batteries together.
lKeep batteries out of the hands of small children.
lIf the unit will not be used for some time, remove the batteries before storage. Leaking batteries
can cause severe damage.
WARNING
CAUTION
This icon indicates a possible danger of loss of life or injury.
This icon indicates a possible danger of injury to personnel or physical damage.

CAUTION
HANDLING OF BATTERIES
lDo not expose batteries to heat or toss into open flames.
lFor the sake of the environment, dispose of used batteries responsibly and in accordance with
local regulations.
lThe batteries that come packaged with the unit were inserted only for device testing purposes.
They may not last long; replace them as soon as possible.
CAUTION
HANDLING OF A BLUETOOTH DEVICE
lThis is a Bluetooth low-energy compatible device. It cannot be connected with any other wireless
communication protocol.
lThis device has been certified as having the proper wireless system for low-power electronic
communication. Do not remove the label of certification from the device. It is against the law to
tamper with the device by disassembling, and/or altering operation. Doing so may result in
criminal prosecution.
lThis device communicates using a 2.4GHz frequency range. This range is also used by the
following wireless transmitters: commercial, scientific, and medical devices and other similar
devices, wireless transmitters used to detect moving object on factory lines (which require
licensing), low-power wireless transmitters which do not require licensing, and amateur wireless
transmitters, all of the above designated herein as “other wireless transmitters”. Before using,
make sure there is no such wireless transmitter in the vicinity which could cause interference. If
you find that the operation of this device near another wireless transmitter is causing
interference, increase the distance between the devices or if possible, turn off the other device.
IMPORTANT
lDo not use in areas with high levels of dust, oil smoke, steam, damp, or high heat.
lIf the unit gets wet or submerged in liquid, immediately turn off and consult your vendor.
lDirt and other contaminants in the measuring chamber can cause erroneous readings. Before
using, make sure the measuring chamber is clean; if not, carefully wipe away all contaminants
with a cotton swab or gauze/soft cloth.
lDo not swing the device by its strap. This could damage/loosen the water-resistant packing in the
device.
lYou may be subjected to penalties to use this device in the country not authorizing the device
usage due to its restrictions on wireless use.
lCommunications errors or reductions in communication speed may result when using the device
in the proximity of a 2.4GHz wireless LAN. Keep the device and the communicating tablet as close
to each other as possible to avoid this.

2. measure known concentration sample data;
3. check the results by graphing the data.
CAUTION
Before beginning the procedure, be sure to tap the Clear Button (3-4 (1)) to clear previous data.

curve (refer to Page 19).
(5) Tap the RGB Select Button to check that the baseline data
values for R, G, and B are not 65535. If the values show 65535,
this means the measurement has saturated, and further
absorbance measurements are not possible.
(6) If one of the RGB levels is saturated, return to step (2),
lower the LED output level in the input box, and measure
again.
If a change is made, select “Yes” when the Clear Data
Confirmation Notice appears, as shown in Illustration 3-5,
to clear the previous data.
