Locale
Locale optionally changes the settings on the DSQD
based on the region where the receiver is being used.
There are two options available:
NA: (default setting) represents the North American
locale and has restricted operation over the As-
tronomical Band (from 608 to 614 MHz). It allows
tuning from 470.100 up to 607.950 MHz.
EU: represents the European locale, and has unre-
stricted operation over the entire band of the device:
470.100 up to 614.375 MHz.

Wireless Designer
Download the Wireless Designer software installer from
the web sites under the SUPPORT tab at:
http://www.lectrosonics.com/US
Wireless Designer only needs to be installed the first
time the software is used. Once the software is in-
stalled, updates are available by simply clicking on an
item in the Help Menu.
NOTE: If Wireless Designer is already installed,
you must uninstall it before attempting to install a
new copy.
Firmware Update
Instructions
Firmware updates are made with a file downloaded
from the web site and the DSQD connected via USB.
The USB port on the transmitter requires a micro-B
male plug on the connecting cable. The other end of
the cable would normally be a USB A-Type male con-
nectorto fit the most common type of USB jack used on
computers.
Refer to
Help
in Wireless Designer software for the
procedure.
