For set up, make sure the mixer or other system in put used
for the CSR-1000 is muted or turned down to a minimum
level.
8.
Plug an au dio cable (not sup plied) into the 3 pin XLR or
1/4 inch out put of the CSR-1000.
a. NOTE: The XLR con nector is the pre ferred con-
nection since the out put is balanced and will be
more immune to noise for longer runs of cable al-
though either can be used with good results. If the
1/4 inch con nector is used, ad just the out put level
on the back panel to 12 o'clock (midway in the
range) to start and ad just later if necessary.
Now refer ahead to transmitter setup and return to step 9
when that is com pleted.

Walk Test the ex pected area of use to check for coverage.
The SOUND CHECK screen is designed to aid this test.
From the main dis play screen, press MENU twice (3 times
in user groups) to dis play the op tions screen. Scroll down
to Sound Check and press set. This Sound Check Screen
will be dis played:
a. The peak hold au dio me ter
allows you to set the
transmitter gain as high as pos sible for the ap pli-
cation which max imizes the signal to noise ratio.
Sing, yell or play the in strument at the loud est de -
sired vol ume and adjust the gain on the meter.
b. The squelch break coun ter will tell you if you
are pushing the range or may have some in terfer-
ence prob lems to contend with. Ideally this count
would be zero for the de sired performance area.
If there are sev eral squelch breaks while walking
the area, adjust antenna place ment or squelch as
in step 11 and re test. Pressing [UP] will turn on
an au
dible tone that will sound each time the
count is in cremented. This tone can be sent to the
monitors or PA so the tester can hear when a drop
occurs and mark the lo
cation on the stage.
Pressing [DOWN] turns the tone off.
c. The high/low RF me ter will tell you if you have
adequate coverage in the performance area. If the
RF level drops significantly dur ing a walk of the
de sired area, re po si tion the an ten nas, ad just the
squelch or change the chan nel and re test.
CAUTION: MUTE OR TURN DOWN THE MIXER OR
AU DIO AM PLI FIERS ETC. BE FORE AD JUSTING THE

Adjustment and press SET. The current squelch setting
will be dis
played, the set ting bar will flash and "Tones
Off" will be displayed (the tone coded por tion of the
squelch must be off in or der to no tice any changes in the
amplitude squelch setting). Ad just the squelch using the
UP/DOWN keys and walk test the unit. Maximum squelch
(all the way right) max imizes noise im munity but lim its
the range. Minimum squelch (all the way left) will max i-
mize the range but al low more noise to break through the
squelch.
