Firmware version 3.1.92 for QT426 and QT446

To upgrade to version 3.1.92, the DVR must have firmware version 3.1.91

This Version 3.1.92 has the following fix:

1. Fix email alert when using Yahoo or Hotmail as the receiver. Now it will show the

image.

These are the Instructions to upgrade QT426/QT446 firmware to version 3.1.9.

Download the file below and save it to an empty FAT32 formatted USB flash.

“TD3520_PACK_SDKV60_F_BLACK_TOOL_BUTTON_IE1_P_US02_BKC_20120217”

Make sure it is the only file on the flash drive (DO NOT unzip this file). Plug this USB flash to

the USB port on the front of DVR. Go to DVR Menu, go to Upgrade icon, select that file and

click on Upgrade. Wait until the DVR reboots by itself and comes back on. This will update the

firmware to version 3.1.92
