To replace MILO 120’s HP-4 amplifier, do the following:
1. Gently slide the amplifier partially back into MILO 120

the user panel, while the harness with green and white
cables goes to the connector closest to the fans.
2. Start all eight screws into the holes before tightening
them.
3. Once all eight screws are started, tighten them using a
#2 Phillips screwdriver.
4. Tighten the inner four screws first, then tighten the
remaining four corners.
CAUTION: Never use power tools in high
torque settings to remove or replace the
stainless steel amplifier and/or rain hood screws on
the MILO 120 loudspeaker.

Perform the following steps to replace MILO 120’s HP-4/

4. Carefully install the fabric rain hood, using the stainless
steel screws and washers.
5. Align all eight screws and make sure that the washers
are over the fabric.

reinforcement bar over the external gasket.
8. Once all eight screws are started, tighten them using a
#2 Phillips screwdriver.
9. Tighten the inner four screws first, then tighten the
remaining four corners.
