An electronic resettable fuse protects the transmitter
from reverse powering. A low transmitter battery
indicator is provided on the CX
iR Receiver.
External powering
The transmitter can also be externally powered by a
number of different cables available from Audio Limited.
The external DC power must not exceed 12V or damage
will occur.
Selecting the operating frequency
Select the operating frequency you want to use from the
label on the side of the TX Blue. Set the F1/F2 switch to
F1 (first column of frequencies) or F2 (second column of
frequencies). Rotate the switch inside the TX Blue
battery compartment using a small screwdriver to select
the frequency, 1 to 16.
Switch the TX Blue off and back on again to enable the
change in frequency.
