I'm having problems connecting to the DR-44WL or DR-22WL with my Android device, are there any settings to improve this?
Some (not all) Android devices have a setting called "Avoid No Internet Connections." This is found in the Wi-Fi settings under Advanced. It tells the device not to "use a Wi-Fi network unless it has an Internet connection." Uncheck this box.
When I record the XLR inputs on the DR-44WL (channels 3 and 4), they record as two mono files. How do I make these record as a stereo file?
Press record once so that the REC light is flashing. Then press 3 and 4 at the same time. In the display they will be joined together. Instead of   it will look like [3 4]. Then you arm them together like you do with 1 & 2 (press one and the other is also armed.)
When I change the input level, can I change more than one channel at a time?
To change the input gain of two channels at once, first press the Input Level button on the side. Next, select the first channel you want to change (e.g. track 1.) Then press the second channel you want to change (e.g. track 2.) Now you can move the input gain knob to change both at once.
"The screen says "ERROR Product" when I try to update the firmware"
There are 2 update files used for the DR-44WL (and DR-22WL), system and Wi-Fi.
To update the System, press MENU and >> while powering on to go into PROGRAM UPDATE mode.
To update the Wi-Fi, press 4 and >> while powering on to go into Wi-Fi F/W UPDATE mode.
The list of available files will show both system and WiFi files, so choosing the wrong one for the current update mode results in the "ERROR Product" message.
I get an error message when trying to update the firmware.
You need to "unzip" the files that you download, ending in ".zip" These files are compressed by the server to make your download times as quick as possible.
On Mac OSX, double-click the file to expand it.
On Windows OS, right-click the file and "Extract All."
How do I know if Wi-Fi is working?
The DR-44WL has a blue LED that shows the Wi-Fi status. Here are the possible mesages from the LED:
Note that the DR-44WL will shut down its WiFi when the battery level gets low, to maximize the remaining record time.
