4.5 Stuck Key Timeout
Stuck key means a button has been pressed for a very long time in normal operating mode.
To preserve battery power, the remote will stop sending code and shut down at about 30 seconds
after the last key transition to consume minimal power. After all keys are released, the remote
resumes normal operation.
Exceptions:
- Mouse L click, navigation keys and “OK” key will not have stuck key timeout.
Typical Stuck Key Timeout is around +/- 20% tolerance, except for IR with exceptional long repeat
timings or RF long latency.
The application will have some mechanism to stop mouse data transmission to save battery life.
In TV Control Setup there are situation where a key is allowed to be pressed for longer than the stuck
key timeout.
4.6 Auto-repeating
All the buttons have auto-repeat function, that is, when a key is continually pressed, the RC will
transmit the corresponding code until the 30 seconds Stuck Key timeout.
4.7 Low Voltage Detection
The RC comes with 2 pairs of 2 pieces 1.5V batteries working in series to give a total maximum of
3.0V ~ 2.5V.
The depletion of the battery power will be in 2 stages.
Note: Remote side will only show low voltage indication when remote is flipped from KB to RC side at
least once when remote is in low voltage.
1) Stage 1, Working voltage (3.0V to 2.5V)
All keys and functions will work as normal.
2) Stage 2, Very Low voltage (2.5V and below)
Very Low voltage detection triggers from 2.5V and below.
No IR or RF codes will be sent from the RC.
Note: All the voltages have a 0.05V tolerance.
