TX/DX low battery indicators
Illuminate when the unit detects low battery power in either
the TX2040 Pocket Transmitter or DX2040 Receiver. The units
should not be used when a low battery power indicator is
illuminated as poor operation may result.
Note: The low DX battery indicator does not function when
the receiver is externally powered via Audio Ltd’s cables.
This is not a fault.
No-signal indicator
Illuminated when no carrier signal is being received, such
as when the transmitter is switched off or set to an incorrect
frequency.
Setting up the DX2040
To set up the DX2040 in conjunction with a TX2040 or HX2040:
• Fit the batteries.
• Connect the A and B antennae.
• Connect the audio output cable.
• Slide the On/Off switch to the On position.
• Select the operating frequency.

and that the red ‘No signal’ indicator is not illuminated.
These steps are explained below:

To open the battery compartment, slide the release catch
towards the centre of the DX2040 and flip open the cap.
