Push round end of Bottom Housing Assembly into hous-ing until it clicks. Add batt door and rec tube
Note: For painted HSG, the plastic are thicker than molded parts. The ASM will require a bit more force to assemble. Af-ter mounting a painted repl kit, the following recommended testing procedure must be followed. Then follow normal test procedures
Close batt door till you get resistance but do not close it completely or it will damage batt pill and/or HSG parts

HI Test for HP, NP & LP Devices: • Capture current customer settings in Aventa.• Connect to NP test fixture. The device is now tested in NP parameters with NP rec. Proper prog cable and batt pill are required.• Run correct HI model TPI. • If test failed, repair the HI and run test again. • If test passed, recall saved customer settings from Aventa and ship back to customer.
Important Note: The device will remain NP device until the previous customers settings from Aventa are restored and using HP or LP receiver to connect to the device, would revert the device back to being HP or LP Device. Failure to do so would compromise the output of the device.
Rec Test for HP Receiver only:• Connect the HP receiver tube on a known good device.• Properly place the assembled device in the sound chamber of test machine to test. Proper prog cable and a fresh battery are required. • Run the HP receiver test TPI • If test failed, rec needs to be replaced. • If test passed, the rec is OK and can be mounted the to the repaired HI.
Rec Test for NP Receiver only:• Connect the NP receiver tube on a known good device.• Properly place the assembled device in the sound chamber of test machine to test. Proper programming cable and a fresh battery are required. • Run the NP receiver test TPI • If test failed, rec needs to be replaced. • If test passed, the rec is OK and can be mounted the to the repaired HI.
Rec Test for LP Receiver only:• Connect the LP receiver tube on a known good device.• Properly place the assembled device in the sound chamber of test machine to test. Proper programming cable and a fresh battery are required.• Run the LP receiver test TPI • If test failed, rec needs to be replaced. • If test passed, the rec is OK and can be mounted the to the repaired HI.

Attach prog cable and batt pill. Position the fixture with HI in soundbox, with the mic hole facing the speaker
Run correct final HI TPI test
Connect device to NP rec tube con-nector. Mic cover should not be on device when testing
Connect coupler insert to the rec tube. Ensure that there is small gap between the insert and rec tube for strain relief

No Mic cover
Correct Placement on Fixture Wrong Placement on Fixture

Properly oriented device on Rec Tube connector
Not oriented prop-erly on Rec Tube connector
No gapTo use the fixture with Dot2 you will need to modify the fixture by remov-ing the small tap fixing the HI on the fixture. The tab can be removed with a cutter or a sharp knife. After modification the fixture can still be used for Dot without PB

Position the fixture with hearing instrument as shown in the soundbox
Run HP Receiver TPI test
• Remove Dome attached from HP Rec Tube (if any).• Connect the HP Rec Tube to a known good DOT/DOT2 HI. • Wrap blue putty around the Rec tube. Be careful not to block the opening of the rec.• Insert rec with a blue putty wrap to the insert coupler. Do not let any part of the rec touch the coupler. Push the back end of the orec in the center hole of the insert coupler until the front end of the rec is flushed to the backside opening of the insert coupler.• Place a fresh battery and connect flex programming cable to the device.• Connect the insert coupler to the 2cc coupler as shown.

First attach the NP or LP receiver to a known good DOT/DOT2 HI, do not use the returned HI to verify the receiver. Any new DOT/DOT2 HI in inventory could be used. Connect cable and battery pill to device and correct coupler insert
Note: When attaching battery pill and flex cable on a painted housing, do not close battery door with pill all the way through. Leave a small gap when closing battery door but enough to function with the flex cable.
Position the device approximately vertically in the middle of the box. Be sure that point where the tube and hearing aid meets is positioned above calibrated spot (middle of the green circle inside the test box). Do not try to lean the device on the coupler. Close the sound chamber.
Run TPI for NP or LP Receiver Tube
Note: LP rec is for HI DOT2 only

When replacing Receiver Tube, be sure to attach it to a device before screwing down the Top Plate of the fixture. This will help ensure the connector is oriented properly
Do not replace Receiver Tube by itself. This may lead to an improperly oriented connector
