Notes on waterproof and dustproof performance

●IPX5 means that the phone will function as a phone even if it is sprayed with water from a nozzle with an inner diameter of 6.3 mm from a distance of about 3 m at a rate of about 12.5 liters per minute from any direction for at least 3 minutes. ●IPX8 means that the phone will function as a phone when it is gently submerged in tap water at room temperature to a depth of 1.5 m in still water, left for about 30 minutes, and then removed. ●IP5X refers to the degree of protection, and means that the phone will function as a phone and remain safe when it is placed in a device containing dust particles with a diameter of 75 µm or less for 8 hours and agitated, and then removed. The dustproof performance of this unit guarantees a degree of protection equivalent to IP5X, and does not guarantee that it will be used in a manner such as placing it directly on sand on a beach. ●The waterproof function of this unit is only compatible with fresh water and tap water at room temperature (5°C to 35°C). Do not pour or soak the following liquids (e.g. warm water, water containing soap, detergent, bath salts, seawater, pool water, hot springs, boiling water, etc.). Also, do not allow sand or mud to adhere to the device. ●Use the device in an ambient temperature range of 5°C to 35°C and humidity of 35% to 90%. ●This device maintains its waterproof and dustproof performance when the battery cover is tightly closed. ●Accessories and optional items are not waterproof or dustproof. Do not use the device in a location where it may get wet. ●Never charge the device when it is wet. This may cause abnormal heat generation, burning, fire, malfunction, burns, etc. due to electric shock or short circuit. ●Do not leave water droplets on the mouthpiece, speaker, external connection terminal, etc. This may cause communication problems. ●When using the device, make sure that the battery cover is securely closed. ●To maintain waterproof and dustproof performance, we recommend replacing parts every two years regardless of whether there is an abnormality (charge applies).
