BACKLIGHT
Once the enabling procedure is complete, the keyboard backlight is on, along with the ON/OFF key, and then it turns off.
It switches on again for a short amount of time when any key, or a 2 key combination, is released. It can also be turned on
manually, without pressing any key, by quickly pressing and releasing the ON/OFF button.
Disabling the transmitter
The disabling of a transmitter, that is in operational status, can take place automatically and manually.
Automatic mode: If within three minutes, no keys or ON/OFF button are pressed, the transmitter is disabled (the ON/OFF
key switches off).
Manual mode: the transmitter can also be disabled manually, without waiting 3 minutes. Keep the ON/OFF key pressed
and it will pass from continuously on to off. If the button is released before it turns off, the transmitter will not be disa-
bled.
Low battery signal
It is recommended to replace the battery within a short period of time if the transmission LED is red during operation.
The residual autonomy time depends on the type and quality of the battery used.
