Real Time Requirements - Vizio KWR600001/01 User Manual

2.2.7 Stuck Key time out function
Stuck Key means that a key has been pressed for a very long time in normal operating mode.
To preserve battery power, the remote will shut down after 25-30 seconds after the last key
transition to consume minimal power. After all keys are released, the remote resumes normal
operation.
The following diagram shows the time limit when the stuck key power down mode is entered.

If more than one key press is detected, remote controller will stop sending IR code.
2.2.9 Standby mode

2.3 Real time requirements

There will be data transmit latency on both Bluetooth interface and GPIO interface, compare
the timing, the BT latency is much heavy, around 100ms (maximum).
