Setting up the TX 2020
To set up the TX 2020 in conjunction with a DX 2020:
• Fit the battery.
• Set the transmitter and receiver to the same
operating frequency.
• Connect the antenna.
• Switch on.
• Connect the microphone.
• Check that the receiver’s ‘No signal’ indicators are
not illuminated.
• Set the microphone gain.
These steps are explained below:
Fitting the battery
To open the battery compartment press the release
buttons at each end of the battery tray and slide out the
tray. Insert a 6LR61 type 9 volt alkaline battery, observing
the polarity as shown on the inside of the tray, and
replace the tray. Do not use excessive force.
An electronic resetable fuse protects the transmitter
from reverse powering. A low transmitter battery
indicator is provided on the DX 2020 Receiver.
Selecting the operating frequency
Select the operating frequency you want to use from the
label on the side of the TX 2020. Set the F1/F2 switch to
F1 (first column of frequencies) or F2 (second column of
frequencies). Rotate the switch inside the TX 2020
battery compartment using a small screwdriver to select
the frequency, 1 to 16.
Switch the TX 2020 off and back on again to enable the
change in frequency.
Connecting the antenna
Connect the flexible antenna to the SMA connector.
Connecting the audio input
Connect the microphone or line level input to the six-pin
Lemo connector. Both positive and negative bias
voltages are provided, enabling the majority of lavalier
microphones to be used with the TX 2020.
