WARNINGS:
- Battery polarities must be correctly installed; otherwise, damage may be caused to the equipment.
- Please remove the batteries if the equipment will not be used for a long time.
1.3 Lanyard Installation
A. Pass the thinner end of the lanyard through the hanging hole.
B. Loop the thicker end of the lanyard through the thinner end and tighten the lanyard.
1.4 Before Operating
A. Before use, check and confirm that the user's finger size is appropriate.
B. Before use, check and confirm that the environment contains only non-combustible material, and avoid high or low temperature and humidity. Pay attention to the following:
- a) Avoid glare and exposure to direct sunlight.
- b) Avoid infrared radiation or ultraviolet radiation.
- c) Avoid contact with organic solvents, mist, dust, or corrosive gas.
C. The equipment should not be used on the hand of an arm tied with an arterial canal, when using a blood pressure cuff, or when receiving an intravenous injection.
D. The equipment may not work normally on patients with microcirculation barriers. Warming or rubbing the finger, or re-positioning the equipment could improve the measurement.
E. The patient should not use enamel or other makeup.
F. Avoid inserting a wet finger into the probe.
Notes:
- A. The user should fully insert the finger into the probe.
- B. It is recommended to let the LED light shine directly on the nail.
- C. Do not shake the finger. Try to keep still during the measurement.
1.5 Operation
A. Press the bottom of the equipment to open the probe, then insert one finger into the probe.
B. Turn on the oximeter by pressing and holding the power button for about 2 seconds.
C. After about 8 seconds, the measurement result can be read directly from the display screen.
D. Before reading the parameters, ensure that the pulse oximeter numbers have remained stable for more than 4 seconds.
E. The equipment will turn off automatically in 8 seconds after the finger leaves the probe.
1.6 Function and menu operation
To set the menu, turn on the oximeter. When the parameter setting interface is displayed, set it by pressing the power button. A long press (1-2s) will set the button hold time, and a short-press (less than 0.5s) will set the button hold time.
On parameter interface 1:
- Move the '*' symbol to the corresponding option, and hold the button to set alarm or beep to on or off.
- When alarm is set to on and the measured SpO2 or PR values go beyond the upper or lower limit, the oximeter gives an alert sound.
- When alarm is set to off and the measured values go beyond the limit, the Oximeter will not give any alert sound.
- When beep is set to on, a ticking sound synchronized with the pulse is emitted during the measurement; when beep is set to off, no sound will play.
- While the '*' symbol stays on the restore option, hold the button to restore factory settings.
- Press the button to select a brightness level ranging from 1 to 5. The greater the value, the brighter the screen.
On parameter interface 2:
- Press the power button again to switch between options. On this interface, you can set the upper and lower limits of SpO2 alarm and PR alarm.
- While the '*' symbol stays on the +/- option, hold the button to set the option to + or -. In + mode, select the corresponding option and hold the button to increment the upper or lower limit. In - mode, hold the button to decrement the upper or lower limit.
- Move '*' to the exit option, and hold the button to return to the monitoring interface.
Figure 5 shows the setting interfaces of the oximeter.

Notes:
- The claim for oxygen saturation accuracy should be supported by clinical studies covering the entire claimed range. The fraction of inspired oxygen (FiO2) delivered to test subjects is varied to achieve a series of targeted steady-state saturation periods over the specified SpO2 accuracy range (e.g., 70% to 100%), then the SpO2 accuracy is calculated by comparing SpO2 readings of the pulse oximeter to the values of SpO2 determined with a Co-Oximeter.
- The clinical trial included 11 subjects, including 6 males and 5 females, with an age range of 18 to 46 years and with varied skin color.

Guidance and manufacturer's declaration – electromagnetic immunity
The RES5102 is intended for use in the electromagnetic environment specified below. The customer or the user of the RES5102 should assure that it is used in such an environment.
| Immunity test | IEC 60601 test level | Compliance level | Electromagnetic environment - guidance |
|---|---|---|---|
| Conducted RF IEC 61000-4-6 | 3 Vrms 150 kHz to 80 MHz 6 Vrms 150 kHz to 80 MHz outside ISM bandsa | N/A | Portable and mobile RF communications equipment should be used no closer to any part of the Model RES5102, including cables, than the recommended separation distance calculated from the equation applicable to the frequency of the transmitter. |
| Radiated RF IEC 61000-4-3 | 10 V/m 80 MHz to 2.7 GHz | 10 V/m | Recommended separation distance d = [3.5/V1]√P 80MHz to 800MHz d = [7/E1]√P 800MHz to 2.7GHz |
where P is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer and d is the recommended separation distance in metres (m).
Field strengths from fixed RF transmitters, as determined by an electromagnetic site survey, a should be less than the compliance level in each frequency range.b
Interference may occur in the vicinity of equipment marked with the following symbol: ((()))
NOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.
Frequency Bands and Compliance
A. The ISM (industrial, scientific and medical) bands between 0,15 MHz and 80 MHz are 6,765 MHz to 6,795 MHz; 13,553 MHz to 13,567 MHz; 26,957 MHz to 27,283 MHz; and 40,66 MHz to 40,70 MHz. The amateur radio bands between 0,15 MHz and 80 MHz are 1,8 MHz to 2,0 MHz, 3,5 MHz to 4,0 MHz, 5,3 MHz to 5,4 MHz, 7 MHz to 7,3 MHz, 10,1 MHz to 10,15 MHz, 14 MHz to 14,2 MHz, 18,07 MHz to 18,17 MHz, 21,0 MHz to 21,4 MHz, 24,89 MHz to 24,99 MHz, 28,0 MHz to 29,7 MHz and 50,0 MHz to 54,0 MHz.
B. The compliance levels in the ISM frequency bands between 150 kHz and 80 MHz and in the frequency range 80 MHz to 2,7 GHz are intended to decrease the likelihood that mobile/portable communications equipment could cause interference if it is inadvertently brought into patient areas. For this reason, an additional factor of 10/3 has been incorporated into the formulae used in calculating the recommended separation distance for transmitters in these frequency ranges.
C. Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the YM201 is used exceeds the applicable RF compliance level above, the YM201 should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the YM201/YM301.
D. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
