JPD-500F
FCC Statement
This device complies with Part 15 of the FCC Rules. Operation is subject
to the following two conditions :
(1) this device may not cause harmful interference.
(2) this device must accept any interference received,including interference that
may cause undesired operation.
NOTE: This equipment has been tested and found to comply with the limits
for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits
are designed to provide reasonable protection against harmful interference in
a residential installation. This equipment generates, uses and can radiate
radio frequency energy and, if not installed and used in accordance
with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off
and on, the ser is encouraged to try to correct the interference by one or more
of the following measures:
● Reorient or relocate the receiving antenna.
● Increase the separation between the equipment and receiver.
●Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected.
●Consult the dealer or an experienced radio/TV technician for help.
Warning: Changes or modifications to this unit not expressly approved by the
party responsible for compliance could void the user’s authority to operate
the equipment.
Precautions
Do not attempt to maintain the Oximeter unless you are professional
engineers. Only professionals with maintenance qualification are allowed
to perform interior maintenance as necessary.
Periodically change the contact position between the Oximeter probe
and the finger for a measurement that lasts a long time. Adjust the
position of the probe before the measurement lasts two hours, and check
the integrity of skin, the blood circulation condition of the finger as well
as the position of the finger.
This product is not applicable to the examination of newborn babies.
Seek for medical care in time if the measured value goes beyond the
normal range while you are sure that the instrument does not
malfunction.
Do not directly expose your eyes to light-emitting components of the
Oximeter, as that could cause harm to your eyes.
For details about clinical limitations and contraindications, please
carefully consult relevant medical literatures.
The following factors may cause disturbance to or affect the accuracy of
examination:
◆ This product is used in an environment involving high-frequency devices,
such as high-frequency electric knives and CT apparatuses.
◆ The probe of the Oximeter is placed on the same body part or limb as
with blood pressure cuff arterial duct or intravenous injection.
◆ The user suffers from hypotension, severe vascular atrophy, severe
anemia, or low oxygen.
◆ The user is in sudden cardiac arrest or shock state.
◆ The finger with nail polish or a fake fingernail may cause wrong readings
of pulse oxygen saturation.
Warnings
Warning: Do not use the Oximeter in an environment with any inflammable gases,
inflammable anesthetic, or other inflammable substances.
Warning: Do not attempt to charge any common dry battery, as that could cause
leakage, fire disaster, or even explosion. Dispose of exhausted batteries in
accordance with environment protection regulations.
Warning: Do not use the Oximeter in an MRI or CT environment.
Warning:Do not operate the Oximeter when it is damp with overflow or water
vapor condensation. Avoid moving the Oximeter from an excessively-cold
environment to a high-temperature moist environment.

Overview
Oxygen saturation is the percentage of oxyhemoglobin (HbO2) that is combined
with oxygen against all combinable hemoglobin (Hb). It is an important physiological
parameter involved in respiration and circulation.
The oxygen saturation of arterial
blood in a normal human body is 98%. Oxygen saturation is an important indicator
of the oxygen condition in the human body. In general, the normal values of oxygen
saturation shall not be lower than 94%. If the measured value of oxygen saturation
is lower than 94%, an insufficient supply of oxygen is considered.
The pulse rate is the number of pulse beats per minute. Normally, the pulse rate is
consistent with the heart rate. In general, the pulse rate of every people is 60 to 90
beats per minute.
The Perfusion Index (PI) usually reflects the limb perfusion status of an examined
patient, and shows the detection precision of the instrument as well; that is,
examination can still be performed even in the low or weak perfusion condition.The
PI of a normal human body is 3% or greater.
Working Principles, Expected Usage, and Applicable Scope
Based on full digital technology, the Finger Pulse Oximeter non-invasively measures
the actual content (oxygen saturation) of oxyhemoglobin (HbO2) in arterial blood
using the optical transmittance method.
The Finger Pulse Oximeter measures the blood oxygen saturation and pulse rate of
a human body via finger artery. It is applicable to a wide range of fields, such as
families, hospitals (including operation rooms of the departments of internal
medicine and surgery, the department of anesthesiology, the department of
paediatrics, and intensive care rooms), oxygen bars, social medical care institutions,
and sports & health. Use this instrument for measurement before or after sports.
You are not advised to use this instrument during sports activities. It is applicable to
patients 15 to 60 years old. Do not use it for continuous care for patients.

Power-On Key/Functional Key Operations
After powering on the Oximeter, hold the power-on key/functional key for about
one second. The Oximeter shows a parameter setting interface. Press or hold the
power-on/functional key to perform corresponding operations. Hold it to set an
item, or press it to switch an option or switch the display mode. Press means no
more than 0.5 seconds, while Hold means more than 0.5 seconds.
Alert Sound Setting
Hold the power-on key/functional key while the Oximeter is in powered-on state.
Parameter setting interface 1 is displayed, as shown in the following figure. Move
"*" to the corresponding option, and hold the functional key to set Alm to on and
set Beep to off. When Alm is set to on and the measured values of the blood
