You may wish to begin by ensuring you have current firmware
images. These are distributed as part of the AltOS software

=== Updating TeleMega, TeleMetrum v2, EasyMega, EasyMini or TeleDongle v3 Firmware
- Self-programmable devices (TeleMega, TeleMetrum v2,
- EasyMega and EasyMini) are reprogrammed by connecting
- them to your computer over USB

. Attach a battery if necessary and power switch to
the target device. Power up the device.
. Select the image you want to flash to the device,
which should have a name in the form
<product>-v<product-version>-<software-version>.ihx,
- such as TeleMega-v1.0-1.3.0.ihx.
+ such as EasyMini-v1.0-1.6.0.ihx.
. Make sure the configuration parameters are
reasonable looking. If the serial number and/or RF
connectors will force the boot loader to start, even if the
regular operating system has been corrupted in some way.

TeleMega::
Connect pin 6 and pin 1 of the companion
battery. Pin 7 carries 3.3V and the board will crash
if that is connected to pin 1, but shouldn't damage
the board.

battery. Pin 7 carries 3.3V and the board will crash

battery. Pin 7 carries 3.3V and the board will crash
if that is connected to pin 1, but shouldn't damage
the board.

+ ifdef::easymini[]
EasyMini::
Connect pin 6 and pin 1 of the debug connector, which
identified by the square pad around it, and then the
pins could sequentially across the board, making Pin 6
the one on the other end of the row.
+ endif::easymini[]
+ ifdef::telemetrum[]
TeleDongle v3::
Connect pin 32 on the CPU to ground. Pin 32 is closest
to the USB wires on the row of pins towards the center
of the board. Ground is available on the capacitor
next to it, on the end towards the USB wires.
+
+ TeleBT v4::
+
+ Connect pin 30 on the CPU to ground. Pin 30 is the 6th
+ pin from the right on the top when the unit is oriented
+ such that the SMA is at the top.
+ endif::telemetrum[]
Once you've located the right pins:
the board has been powered up, you can remove the
piece of wire.
