INTERFACE INTRODUCTION

Settings interface

Long press ON/ OFF

Click on the sensitivity button to select the appropriate sensitivity.

Click on on the timing button to select timing.

Click the plus or minus button to select the appropriate flow.

DIRECTIONS FOR USE

1、Power supply

Select the appropriate power connection conditions based on the usage environment.

When only using batteries, install the dedicated battery for this device to the device battery interface.

When using the on-board power adapter, when the power indicator on the adapter lights up.

it indicates that the power connection is normal.

Required input terminal: DC 19v 65VA MAX.

When using the AC power adapter, connect the AC power adapter and the power cord firmly. When the power indicator on the adapter lights up, it indicates that the power connection is normal.

Required input terminal: AC 100-240V, current 2.0-1.0A, and frequency 50/60Hz.

Warning: Do not use lithium batteries that are not included with the product.

2、Startup preheating

Press the device ON key, and after hearing a "tick" boot prompt tone, enter the boot screen.

After the system starts, the device enters a warm-up state. The preheating time of the equipment is about 2 minutes. After the preheating is completed, when the equipment status meets the requirements for normal use, it can be worn and equipped with a nasal oxygen tube for normal use.

Note: During the warm-up period of the machine, the device will automatically inject oxygen to empty the internal air, At this time, the output flow and concentration of the device may not meet the standard, so do not use it.

Note: Do not connect the nasal oxygen tube during the warm-up period of the machine

3、Connecting the nasal oxygen tube

Connect the factory equipped nasal oxygen tube bell mouth to the metal air outlet of the equipment to ensure reliable connection and no air leakage. Note that the nasal oxygen tube should not be kinked or blocked to avoid causing equipment related alarms and affecting normal use.

Note: This device is a pulse oxygen supply method. To use this device, it must be connected to a nasal oxygen tube.

4、Adjusting the flow gear

To adjust the flow gear, please press the setting key to set the flow gear according to your needs

5、Turn off

When the device is working normally, press and hold the ON/ OFF key for about 3 seconds, and the device emits a "beep" prompt and enters the shutdown interface. The device automatically shuts down.

6、Other information

When the adapter is connected/ unplugged or the battery is connected/ unplugged, the device will emit a "tick" prompt, and the main interface of the device will also have relevant information to display the current power supply status.

When an abnormal state occurs, the abnormal information indicator light will light up, and the device will display abnormal information and issue an audible prompt. if you have learned the prompt information and no longer need a prompt tone, you can press the prompt tone switch to turn off the information prompt tone.

Note: When the alert tone is turned off, please pay close attention to the device status to prevent you from not being able to fully grasp the device operation without the alert tone

Note: It is prohibited to remove the battery during equipment operation.

MAINTENANCE AND CLEANING

1. Replacement of intake filter cotton

• 1.Shut down the device, disconnect the power supply and remove the battery
• 2.Remove the filter cotton bottom shell.
• 3.Take out the intake filter cotton. Note that the intake air filter cotton after long-term use mayabsorb and accumulate a large amount of dust. Please operate with care and take properprecautions to prevent inhalation of dust.
• 4.Install new filter cotton in the correct direction
• 5. Install the filter cotton bottom shell back.
• 6.Please properly dispose of the waste filter cotton

Note: Failure to install or replace the filter cotton for a long time may affect equipment performance or damage the equipment. Please replace the filter cotton in a timely manner, and the replacement cycle depends on the use environment and usage. Generally, it is replaced once a month.

2. Molecular sieve replacement and maintenance

1. When the device prompts the need to replace the molecular sieve, please contact the designated seller in a timely manner.
2. Long term storage may shorten the service life of molecular sieves.
3. Long term operation in a humid environment may shorten the service life of molecular sieve.

Warning: Do not disassemble and replace molecular sieves without permission. Only equipment suppliers or qualified maintenance engineers can disassemble and replace molecular sieves.

3. Nasal oxygen tube replacement

Users can purchase nasal oxygen tubes as needed, but they need to ensure that the following conditions are fully met:

1. Please contact the equipment provider or purchase under the guidance of a professional (Official Sore:https://dedakjoxygenconcentrators.com/ ).
2. Please purchase from regular channels.
3. The rated flow rate of oxygen in the nasal oxygen tube is 5 liters per minute, and the total length is between 1 and 7.5 meters
4. It can fit well with the air outlet of this product without air leakage.

Please wear a nasal oxygen tube correctly and use it according to the instructions for using the nasal oxygen tube.

4. Battery replacement and maintenance

This device requires the use of a dedicated battery provided at the factory, with a standard battery provided at the factory. Users can contact a designated seller to purchase batteries as needed.

Battery life: 500 cycles of charge and discharge capacity reduced to 80%.

When not in use for a long time, please remove the battery from the device and pay attention to protecting the battery electrodes from contacting conductors such as metals to prevent fire and other hazards.

7. Equipment cleaning

Before cleaning, please ensure that the machine is turned of, unplug the power supply from the socket, and remove the battery.

The power off sequence should be to first disconnect the power plug on the wall and then disconnect the plug on the machine side.

Do not let the equipment get wet or enter water, Once this happens, it will lead to equipmen failure or shutdown, and it will also increase the risk of electric shock.

Do not pour liquid directly onto the machine. Chemical cleaning agents used on the plastic exterior of the machine may damage the plastic housing of the equipment. These cleaning agents include, but are not limited to, the following lists: alcohol and alcohol products, high concentration chlorinated solutions (chloroethane), and oil products (Kolol).

Be careful not to allow liquid to enter the interior of the machine. Pay special attention to ensuring that the oxygen outlet is free of dust, water, or other particles.

Do not use organic solvents or other flammable and explosive volatile substances for cleaning.

Please ensure that the equipment has been completely dried before use.

Warning: Before disposal, remove batteries, etc., and contact relevant departments to properly dispose of equipment and accessories in accordance with local government regulations.
