A1: The explosion-proof marks of this mobile phone are Ex ib IMb, Ex ib IIC T4 Gb, and Ex ib IIIC T130℃ Db. Ex represents the explosion-proof mark, ib is intrinsically safe type, I is suitable for coal mine gas environment, IIC is suitable for Class II explosive gas environment other than coal mine gas, and IIIC is suitable for combustible dust environment. T4 and T130℃ respectively represent the surface temperature groups of the equipment. Mb, Gb and Db are the protection levels of devices. It can be used in Zone 1 and Zone 2, gas environments of Class IIA, IIB and IIC, as well as combustible dust environments.
Q2: The KTW399 (5G) explosion-proof smartphone has a rich variety of network standards. How does its network speed perform under different networks?
A2: the phone supports GSM/WCDMA/CDMA/FDD/TDD/SA/NSA and other network systems. Under 5G networks (SA/NSA), if the network environment is good, theoretically, high download and upload speeds can be achieved to meet the demand for rapid data transmission. Under other network standards, the network speed may vary according to the standards of the corresponding network and the actual environment, but it can still meet the basic communication and data usage needs in daily life.
Q3: The battery capacity of the KTW399 (5G) explosion-proof smartphone is 6000mAh. How long does it take to fully charge it?
A3: The charging time of a mobile phone is affected by various factors such as the power of the charging device, the remaining battery power, and the phone's usage status. Generally speaking, with the standard charger, it takes about 2 to 3 hours to fully charge a 6000mAh battery when the phone's battery is depleted and the screen is off.
Q4: The KTW399 (5G) explosion-proof smartphone supports multiple positioning systems. How accurate is its positioning in actual use?
A4: This mobile phone supports multiple positioning systems such as Beidou, Galileo, Glonass and GPS. In an open outdoor environment, multiple positioning systems work in coordination, and the positioning accuracy can usually reach within several meters, which can meet the needs of navigation, location check-in, etc. However, in indoor areas or regions with severe signal obstruction, the positioning accuracy may decline.
