Computer boards, tanners, wires, iodine lanterns, ultraviolet light, job stability

(1) power switches: power discharges through/out。
(2) show windows: three displays to show tan parameters and process execution。
(3) reverted bit keys: with recognizance, during program execution, press this key and return to the initial state。
(4) start key: touch the key lightly, i. E. Start the whole tan process。
(5) vacuum keys: use in combination with the set number key, preset, query, modify the vacuum duration。
(6) exposure keys: used in combination with the set number key, preset, query, modify the exposure time。
(7) type a number when setting or modifying a sunscreen parameter。
(8) zero key: shows zero. Note: when the number key is pressed, a beep is made. However, the procedure was not effective during its implementation。
(9) vacuum indicator lamps: when initial state, the indicator light is activated, after a delay of two seconds returning to the exposure key, and when the vacuum delay is performed, the indicator light is activated。
(10) exposure indicator lamps: in the initial state, the pointer light is activated until the " vacuum " key is pressed, the exposure key is valid and the indication light is activated when the exposure program is performed。
