6.4 Viewing microSD Card on PC

To view the files saved in the microSD card of an electronic device on a PC, it is necessary
to unmount the microSD card, remove it from the device, insert it into an SD card adapter or
USB adapter, followed by connecting the adapter to a PC for it to be recognized as a
removable disk.
6.4.1 Mass Storage feature
With the TH-D74A/E, connecting it to a PC with a USB cable, the microSD card can be used
as a removable disk. To make use of this feature, it is necessary to configure the USB
function of the TH-D74A/E to "Mass Storage".
Configure the USB Function to "Mass Storage" in the menu, followed by connecting the
transceiver to the PC using a Micro-USB cable.
Note: The Mass Storage feature of the TH-D74A/E is only supported on Microsoft Windows
systems. Although the microSD card may also be recognized on a Linux OS, the
file size cannot be displayed correctly.

6.5 Adjustment of RX Audio Quality

Different users have different sound quality preferences. The TH-D74A/E comes with an
Audio Equalizer feature that allows users to adjust the sound quality according to their
preference.
6.5.1 DSP audio sound processing
The DSP (digital signal processor) on the TH-D74A/E ensures that all transceiver audio
signals are properly processed. Audio signals in the analog FM mode are also converted
temporarily to digital signals by an A/D converter, after which sound processing is applied
within the DSP and the signals are restored to analog signals by a D/A converter and output
from the speaker.
6.5.2 RX Equalizer
The RX Equalizer feature is made possible by processing of all received audio signals by
the DSP as described above. The audio frequency band of the RX Equalizer is divided into
five (5) different bands, each of which can be adjusted within the range of -9 dB to +9 dB.
User can therefore adjust the frequency properties of the audio signal to their preference.
