Maintenance
Front Feet You will need a torque-limiting Torx T-15 screwdriver and pliers for this
procedure.
Refer to the exploded view diagram for the 2-channel models or the 4-channel
models. (See page 8-4.) (See page 8-6.)
Removal.
1. Remove the power button and rear case. (See page 6-10, Rear Case.)
2. Slide the front feet out of the front case.
Installation. Slide the feet into the slots provided in the front case.
NOTE.
If the front feet are not installed, but are available, they can be inserted
by carefully pinching them and pushing them into their slots. For example, you
may need to do this if the rear case has been removed, and a foot has been rubbed
off and unnoticed until the case is being assembled.
