[NOTES]

: DSP Thru of Listening Mode outputs L Input signal to L/C/SL, and outputs R Input signal to R/SR/SW.

: Config. is in order of SW/FronI/Center/Surround.

: Mute is function to stop output(from the channel) by using inner DSP programming.

: When Listening Mode is DSP thru, an analog SW is changed into the state of SURROUND.

:At the time of PRTCTTHM detection, it is displayed on FLT as "THERMAL PROTECT".

: In all test modes, it is not concerned with detection of VOLH but SEC1 H are made "H" fixation. (Except TEST 1-07 and 1-08.)
: TEST of NET/USB can't do immediately after the start-up.

It should be measure after other TEST.

After initialization of Net or USB, start TEST 1-04.

not installed and used in accordance with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation. If this equipment

does cause harmful interference to radio or television reception, which can be determined by turning the

equipment off and on, the user is encouraged to try to correct the interference by one or more of the following
measures:

-Reorient or relocate the receiving antenna.

-lncrease the separation between the equipment and receiver.

-Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

-Consult the dealer or an experienced radio/TV technician for help.
