2Until you get approval from washington

你就是地区委任专员了。

3B: Yeah, we have to pause until we get approval

乙：是的。我们不得不暂时停下待命。

First, Chiji methods (Note matters):

The method of

① Cross with a screwdriver on the Dike will be removed four screws;

② Dike will open with iron battery is, a negative electrode wire bonding, and then Deke will be removed, Deke camera decorative circle posted a protective film to prevent dust into the camera lens, and then tape battery cathode paste living to prevent and repair damage to short-circuit when the battery cell;

③ PCB board will be the speaker wire bonding, with a screwdriver will cross the PCB board removed four screws, and then remove PCB motherboard, LCD display and a crust removed from the board; (Note: when the demolition of PCB board pay attention to the LCD cable not force, to prevent LCD monitor cable breakage)

Second, the maintenance of

1 Dead:

① at both ends of the battery positive and negative electrodes leads positive and negative two fuses, will be raised to 37 V power supply around long boot by POWER button boot and at the same time observe whether ammeter starting current, without the current inspection POWER patch is a switch No false welding or damage to measurement POWER switch linked to the "VIN"-about whether the voltage of 37 V, in the absence of voltage or low voltage detection Q4 there is damage, R102, R103 whether damage to pave the way; carefully to identify the reasons for the replacement of undesirable components;

② P0WER long boot by boot button, and instantly the current 80 mA-140mA, but to return to the initial state after release, this is the first test for the driver MP4 components are lost If conditions permit can be good from the same type of plane removed FLASH memory IC to be replaced or re-confirmed the escalation trial Upgrade upgrade method reference manuals

③ such as FLASH memory IC replaced or updated procedures did not improve, he was appointed by 10,000 by measuring U6, U17 and U1 IC pin is the pathway, with a multimeter testing of the IC pins whether it is normal for the resistance, whether electricity feet Open, measuring whether there is a short circuit or open the undesirable phenomena;

④ long boot by POWER switches, ammeter shows that current (150 mA-300mA), the reasons for this phenomenon of multiple failures for the mainframe level after the power supply circuit and short circuit or power regulator output circuit abnormal result of this first mainframe If power at all levels: 18 V, 30V and availability of short-circuit or smaller resistance, such as resistance found smaller or short-circuit should be step by step and disconnect the power supply inductance voltage regulator IC, and the measurement circuit on the resistance to change there, when in a certain disconnect circuit back to normal after the resistance, should focus on the detection circuit components related to whether the breakdown, leakage, damage, etc If detected on the 18 V power supply circuit and Resistance smaller or not normal, first disconnect L14 22UH inductance, check whether the short circuit level, and measure whether it is normal load-resistance, such as abnormal load resistance, check C2, C3, C4, C5, C6, C68, C78, C84, C90, BC6, U16 TVP5150 and U1 SPMP3052A whether poor or leakage; such as 18 V power supply normal again detection U12 regulator IC output of 30 V power supply 5 feet on the ground resistivity whether short or resistance Small changes, such as the resistance change is small or short-circuit voltage regulator IC removed measurement of the end-load resistance; such as resistivity anomalies were detected C1, C10, C12, C14, C28, C29, C33, C71, BC4, BC8 , BC10, BC11, BC12, BC13, BC14, U1, U2, U3 (screen), U6, U17 circuit components, and other related damage, or whether the short circuit; carefully to identify the reasons for the replacement of undesirable components; (Note: Due some users in the SD card inserted malpractices led to the SD card inserted deformation caused by shrapnel VDD, VCC, and GND short supply, maintenance, failure to pay special attention here) should be removed to L4 inductance measurement; such as 30 V power supply normal again Cece U13 regulator IC output of 30 V power supply 5 feet on the resistance there is to short-circuit or smaller resistance, such as resistance change is small or short-circuit measurement removed regulator IC Load end of the resistance if the resistivity anomalies were detected C7, C8, C9, C74, C75, C93, U1, U13, U16 circuit components, and other related damage, or whether the short circuit; carefully to identify the reasons for the replacement of undesirable components;

⑤ such as 18 V and 30 V with short or smaller resistance phenomenon, be detected "VBAT" positive change of the resistance is small or short-circuit, the normal resistance should be positive in about 50 K-70K, such as BAT +-no signs of short-circuit , the resistance of normal power supply circuit to detect C60, C61, U15, Q3, and other related circuit there are abnormal, identifying the reasons for the replacement of undesirable components;

filter regulator是 过滤器调节器 滤油器 过滤器

例句：

Obtain new filter/ regulator ( two new o-rings should already be installed)

找到新的滤清器/调节器（两个新O形环应已安装）。

The filter regulator has to be fitted to the gas connector by using tightening tape

用固定胶带把过滤器与气管接头固定。

Test all instrument air headers and piping leads up to the block valve immediately preceding the filter regulator with air at normal operating pressure

在正常 *** 作压力下用空气测试与过滤校准器（仪）前的隔断阀所有相连的仪表集气管及管道。

Rotate filter/ regulator until fuel supply tube ( fitting) is pointed towards front of vehicle ( 12 o'clock position)

旋转滤油器/调整器直到燃油输送管（配件）指向车辆前部（12点位置）。

Another DC power is normally provided by the AC power rectifier, filter, regulator to achieve, so that makes the inevitable power factor is low, leading to job insecurity of other laboratory instruments

另外直流电源一般是由电网的交流电经整流，滤波，稳压来实现的，这样不可避免的使得功率因数比较低，因而导致其它实验仪器工作不稳定。
