The treatment methods of 2 way radio that water was in it

1.Firstly , pull the battery out and take the 2 way radio host apart,including antenna, machine box, circuit boards, conductive rubber, buttons, guide pillar and so on.
2.Clear antenna and conductive rubber button with anhydrous alcohol ,and place it in the air to dry.
3.Just need to blow dry the speaker and microphone under the hair dryer,because the speaker and microphone should not soak with the anhydrous alcohol .
4.Use a reedy tool to remove dirt in each integrated block and platoon line, then soak circuit board with anhydrous alcohol(if condition allows, it can use ultrasonic cleaning machine to clear).Use a soft brush to clear, put it in ventilated place and use hair dryer to blow dry. Pay attention that the temperature of the dryer not too high .Users can put hands on the circuit board.if hands can bear,it means that the temperature is OK.Then check the circuit board wounded or not.If there is a break,connect it with thin wire , and measure power positive and negative resistance of plate with avometer.It should not be short circuit or open circuit(charge with electricity and view current,it is about 40 ma in normal.It cannot be less than 1000 ma in the emission.).
5.Finally, check the wireless mouth dirty or not and clear it if it is dirty.At the same time ,cheek and repair routinely if there are other fault.For the 2 way radio that water was in i,if its circuit is corroded seriously, it will cannot repair. So it should deal with the machine that water was in it in time.
