2. Specification
3. Operation Instruction
(1) Laser Tube connection: (Referring to Power supply and laser device's connection diagram)High voltage terminal(HV+) of HY-DY20 power supply should be connected to the positive pole of CO2 laser device. Current circuit of the power supply shall be connected to negative pole (laser output terminal) of laser device, through an ampere meter or directly.
(2) Connection of control signal: The control signal shall be reliably connected to control terminal of the power supply HY-DY20, after connecting the DAC output signal and TTL signal of external computer with the power supply, the laser device shall work as expected. If the laser lamp can not work properly, should check the control signal is correct or not (include check the voltage specification and logic), if use PWM control as power control,make sure f≥20KHz,Amplitude(peak value)≤5V, check and make sure protection switch WP connection is correct at same time.
(3) Voltage of power input: HY-DY20 's power input of the power supply shall be 220VAC/50Hz. If 110VAC is needed, please specify when placing order.
(4) Others: A group of protection switches are also reserved for detection of water switch, fan switch, open-enclosure protection and so on.

4. Caution:
(1) Water cooling system should be working properly when switching on laser device.
(2) Circuit of high voltage output should not be open! (High voltage output terminals (positive and negative poles) shall be properly connected to positive and negative poles of laser device, respectively).
(3) Attentions should be given to avoid any electric shock after the power supply being switched off (The Insulation safety requirements should be 50KV between the terminal of output and "G").
(4) Well-grounded three-pole receptacle should be used to supply power to HY-HVCO2/1.6 power supply. The enclosure should be well grounded to avoid electric shock.

Natural tan /no orangy hands!
Mine came with the lotion, applicator mitt, and a facial can mist. I haven't used the facial mist yet but here are my observations for the lotion:
PROS
- finish color looked very natural. Not orange at all.
- no streaks / dark patches / missed spots (of course this has to do with the application as much as the product)
- can build darker tan with multiple applications
- did not transfer onto my clothing
- the "self-tan lotion"scent was present but not terrible
CONS
- slight self tanner smell
- made my scars look darker (not a product defect, my scars get darker from the sun too. Just mentioning in case someone has severe scarring /discoloration/ vitiligo to be mindful. First application I would say do full body. And maybe afterward learn to work around your darker skin spots.
I didn't use the mitt for application, but it's nice and soft and comfortable. I used disposable cheapy medical gloves because I felt like I may not get good enough control and might leave streaks with the mitt. (With practice though, I will definitely use it because it feels nice and soft.)

Works great
Color: Medium Glow
This works great and darkens skin to a beautiful light tan but does somewhat wash off the next day so it does require reapplying the next day. I would purchase this again.

A good starter kit
A really good starter kit, the tan isn’t orangey and applies pretty easily. It doesn’t get super dark. The lotion is good to make the tan last longer but wash your hands really well or they’ll have dark splotches. The spray isn’t amazing and can look streaky

Works good
Color: Medium Glow
It smells like tropical scent after putting it on. The smell lingers for about an hour or two. It is not bad though, I like it- reminds me of summer scent. Instant tan works very quick. I am very fair I see no sun so, I put two layers on yesterday and two layers on today. I am significantly tanner. I only use my hands to spread it in, it would work better with less streaks if using a tool to help spread the product evenly. It leaves my skin feeling very smooth and hydrated and I like the color and scent, I like how it has hydrolaunic acid and vitamin c. Works good and stays on. I was able to convince my husband it was good to have because of the hydrolaunic acid and the vitamin c, I said it's a 3-in-1! I also bought this during black Friday week so, got it for a good price.
