Test

Attach the CS44 prog.cable to the USB terminal of the ear-phone prog cable

Insert the USB terminal of the earphone prog cable to the USB port of the HI and turn on the HI

Insert the simulated battery into the HI and place the HI in the test chamber

Slide the coupler with the adap-tor in the fixture and tighten the bolt screw to keep it in place (turn clockwise)

Bolt screw

Prepare the other end of the programming cable plugs. There are two plugs, one with a “PG” mark and the other with no mark. Connect the “ no mark” plug to the earphone when starting test

Note:The prog cable and USB earphone prog cable are needed for testing IBW2 & 3 only. For test of IBW1, an earphone cable is needed instead

Doc 0191600 rev G

Page 20 of 20


Test

Swing the clamp of fixture up and attach the earphone to the coupler. Swing the clamp down and tighten the bolt to minimized leakage from earphone

Place the coupler and test fixture out-side the test chamber as shown

EarphoneBolt screw

The test SW will prompt you to change earphone to “PG” and later back to “No PG”. Unplug the current plug on the earphone and connect required plug to earphone on fixture and click OK. There is no need to open the sound chamber to make the exchange of the cable plugs
