The table below shows which conditions will wake up TC35 and TC35i from sleep mode
As it can be seen from the following table TC35i supports four sleep modes (5,6,7,8)
more then TC35.

* TC35i supports SLEEP modes 0, 5, 6, 7 and 8. Different events or commands cause a wake-up from a SLEEP mode. The
detailed descriptions of these modes can be found in respective HID documents.
4.4.4 Battery pack
For some applications the use of a battery pack may be required. TC35 and TC35i can be
powered from a Li-Ion battery:
