ADJUSTMENTS BEFORE OPERATION

MAIN/CENTER/EFFECT SPEAKER LEVEL BALANCE ADJUSTMENT

This operation uses an internal test-tone generator for balancing
the levels of the main, center and effect speakers.
1. Depress the TEST switch on the remote control so that "TEST
DOLBY SUR." appears on the display panel to enter test mode. A
hiss-like calibration signal should be heard from the left main
speaker, center speaker(s), right main speaker, right rear effect
speaker and left rear effect speaker in turn (see diagram). Adjust the
master VOLUME to a normal listening level.
*
The state of test-tone output is shown by the display panel and
the monitor screen. (On the monitor screen, it is shown by an
image of audio listening room.) This is convenient for adjusting
each speaker level.

2. Adjust the center and rear level by using the CENTER and REAR
LEVEL +/– keys on the remote control so that the sound coming from
the corresponding speaker seems to be at the same level as that
from the main speakers when you are at a normal listening position.
The REAR LEVEL +/– keys adjust the right rear level if pressed while
the test-tone is output from the right rear effect speaker, and adjust
the left rear level if pressed while the test-tone is output from the left
rear effect speaker. If the REAR LEVEL + or – key is pressed while
the test-tone is output from other than the right or left rear effect
speaker, the key adjusts either the right or left rear level that has
been adjusted last time.

If there is insufficient volume from the effect speakers, you may
decrease the main speaker volume level by setting the MAIN
LEVEL switch on the rear panel to "–10 dB", and adjust the
center and rear level again. Volume controls on external power
amplifiers may also be adjusted if necessary to achieve proper
balance.
*
Pressing the Parameter + or – key (only when the
PARAMETER/SET MENU switch is set to the PARAMETER
position) transfers the test-tone from the speaker that is currently
outputting the test-tone to the right or left rear effect speaker.
Pressing "+" transfers the test-tone to the right rear effect
speaker, and "–" to the left rear effect speaker.
*
Pressing and holding the Parameter Select
when the PARAMETER/SET MENU switch is set to the
PARAMETER position) fixes the test-tone on the speaker that is
currently outputting the test-tone.
NOTE: If not using a center speaker, be sure to set the CENTER SP
mode to the PHNTM (phantom) position. You will then hear the
center channel test tone from the left and right main speakers.

    I absolutely refuse to read this excuse of the alleged printed word any farther. I am insulted by the fact that the printing is encoded. What kind of machine printed these words? You should be ashamed of yourselves​. Was this an attempt to somehow save money? Did you have any of your own employees try to read this aloud ? Get real!
