6. Position the ATX transmitter about 6-12”
(15-30 cm) from the front of the CR99 with
the transmitter’s IR window facing the IR
transmitter on the front panel of the CR99
receiver.
7. Make sure the ATX transmitter is fully charged
(see section Charging the ATX Transmitter) Turn
on the power to the transmitter by pressing and
holding the Power button for 3 seconds; the
indicator LED will light yellow when the button
is pressed and turns green when released and
the ATX is powered on.
8. When the transmission is complete, the CR99
will receive RF signal and the tone key from the
transmitter. The RF meter on the CR99 will light
indicating that it is receiving wireless signal
from the transmitter.
Note: The ATX will only accept infrared
transmission from the receiver for the first 10
seconds after the ATX is powered on. If you
need to change the operating channel, the ATX
must be first powered off, then powered on
again to receive the new channel.
9. Turn on your connected amplifier or mixer, but
keep the volume all the way down. Set the
Volume knob on the CR99 fully clockwise (to its
“10” setting). This is unity gain.
10. Plug the microphone into the ATX transmitter. Speak, sing or play your
instrument into the microphone at normal performance level. Slowly raise the
volume of your amplifier or mixer until the desired level is reached.
11. Walk around the performance area to ensure the coverage is consistent
throughout. If you find the system has noticeable dropouts, reduced overall
working range, or unexpected noise bursts, change the operating channel of the
system using the steps above.
When using multiple systems, each system must be set to a different operating channel.
Set all additional transmitters and receivers to the same Group in order to maximize the
number of compatible channels. Perform a channel scan for each transmitter to select the
optimal channel.
