DECT Infrastructure measurements
Receive strength indicator
Maybe all handsets support enabling a test mode for testing the receive strength of up to 4 dect base stations.
- Go into the menu

Test/Trace menu structure
Handsets with the 7.4.5 firmware can be switched into a test/trace mode. The default menu structure will be replaced with a menu structure suitable for testing and measurement.
- Go into the menu
- Type * * * 7 6 #
- You are seeing the “Service” menu now.
- Go into submenu “Data management”
- Change “Menu structure” to “Test/Trace”
USB-Port
The phone can be charged (slowly) with power through the usb port.
The USB-Port can be used to transfer the phonebook or update the firmware.
USB-port mod for 610d
With a bit of soldering skills it is pretty easy to add USB charging to the 610d handset.
The 610d already has on the PCB the receptables for the USB hardware. USB port and some electronics components are just not soldered. For charging via USB, it is easy to solder a microUSB or miniUSB port there. The “-” power connection is already connected, the “+” power connection needs to be connected with a small wire to the “+” pin of the cradle power input. It best can be done on the other side of the PCB – there is a test point connected with the USB “+” pin, use a multimeter to find out which one. Then the 610d can be charged with a dump 5V USB charger. WARNING: Do not plug in USB and charging cradle power input at the same time, since after this modification both are connected in parallel. It might damage external power supplies (or the computer).
SD-Card slot
The SD card needs to be specially formatted by Mitel. It contains a new DECT portable part identifier. The SD card will be used by the phone to store all configuration and user data including the identifier on the sd card.
Anyone out there with an image of such an sd card?
Firmware update
The firmware can be updated by using the USB port or by update over-the-air.
