Support GPRS, WAP2.0, EDGE store 1000 phone book, SMS Storage 1000 WB-M06 ? Explosion phone - production work additional features built-in compass, altimeter and barometer of a button for help: a mobile phone with SOS button for help, fast backward station or designated service center to send a distress message flashlight in a Zone 2 use?? , a key to start flashing SOS signal alarm, SOS distress signal frequency signal in accordance with the international Morse code, a key to start the WB-M06 cell phone explosion - proof design based handset design basis:?.. CB3836.1 CB3836.4 intrinsically safe equipment is defined as: All circuits are intrinsically safe circuits, spark and thermal effects that normal operation under fault conditions or provisions resulting circuit can not ignite an explosive mixture prescribed. WB-M06 cell phone explosion - design approach intrinsically safe explosion-proof phone circuit design: 1, mobile phone components strict screening, the failure rate of a single element is controlled to a minimum; 2, the mobile phone circuit design, all the capacitors, and the strict control of the number of design optimization, the energy stored in the capacitor to ensure the phone in any case can not produce the required spark to detonate gas; 3, the mobile phone circuit design, all inductors, rigorous design and evaluation of energy to ensure that the energy stored in the inductor phone Under no circumstances should a spark to detonate gas needed; 4, mobile phone circuit design, all elements of the assessment work to ensure that under the most adverse conditions, the surface temperature does not exceed the requirements of T5 5, mobile phone circuit design, to India system board wiring, wire diameter strict design to ensure copper phone PCB board in any case can not produce more than the surface temperature T5 requirements; 6, the mobile phone circuit design, the vibration motor, flash inductive device, strict energy limits are designed to ensure that under the most adverse conditions, can not produce sparks, the surface temperature does not exceed the requirements of T5 7, mobile phone circuit design, the power supply voltage clamp section strictly optimized design ensures that in any case the phone can not produce more than 20% of the rated working voltage. 8, mobile structure carefully adjusted to ensure that all with the gap in any case not generate a spark to ignite explosives; 9, cell phone battery design, using no explosion and fire hazard lithium polymer battery cell. 10, mobile phone battery protection board design, redundant design, used current, over voltage, short circuit, low voltage protection, to ensure that the battery does not produce sparks, the surface temperature of no more than T4. 11, mobile surface to take anti-static protection measures to ensure that the process does not produce due to the use of electrostatic discharge causes sparks appear.
