immersed. Additional troubleshooting of the radio will be required; complete this procedure, 
then go to Section 5.8.8 Pressure Test.
7.Remove the vacuum hose and pump connector from the radio.
5.8.8 Pressure Test
Pressure testing the radio is necessary only if the radio has failed the vacuum test. Do not perform 
the pressure test until the vacuum test has been completed. Pressure testing involves creating a 
positive pressure...

9.Remove the pump connector from the chassis.
10.Radio after performing Pressure Test must undergo baking process in a temperature chamber 
for constant temperature soaking at 60°C for 1 hour. This is to ensure no moisture is trapped 
inside the radio and prevent contamination of the internal electronics after reassembling the 
radio.
