2. Functional Requirements
2.1 Simultaneous Key Press (RC)
If more than one key press detected, the remote control will stop sending IR/RF code.
2.2 Simultaneous Key Press (KB)
The remote support multiple key press but only limited keys are able to do so. When two or more
remote KB keys, that do not support simultaneous press are pressed simultaneously, the remote will
not send codes. When only one key is still pressed the remote will restart and send the code of this
key as per normal.
Workable 2 keys simultaneous key presses are;
CAPS with any Alphabets:
ALT with keys with Blue options (numbers and symbols etc)
2.3 Consecutive Key Press (KB)
When ALT key is pressed or still press, the RC will not transmit or do any action. After release and
then press any keys that have alternate function on the same key, eg Q key shares the same as
Numeric '1' key, the RC will transmit Numeric '1' code.
The same is true for CAPS keys. For CAPS, after release of the key, an alphabet key is pressed, the
RC will transmit the capital letter of the particular key.
2.4 Indicator LED
Total 3 Indicator backlit LED.
1) RED colour, on STANDBY key, RC side

Upon pressing of any valid key, a LED fast blink of 50ms will be shown just before IR/RF
transmission.
2.5 Power Management
2.5.1 Stuck Key Timeout
Stuck Mode function is use to conserve battery life. When a key is being press continuously for
~30 seconds (e.g. by placing something heavy on top of the remote) the remote will stop
transmitting code automatically after 30 seconds and will resume operation when all keys are
released. Typical stuck key time is between 27 and 33 seconds with a tolerance of +- 3sec.
2.5.2 Low Voltage Detection
The RC comes with three 1.5V batteries working in series to give total maximum 4.5V.
LED blinking dependant on the side, red LED for RC, amber LED for Keyboard.
Low voltage detection triggers when the battery voltage is at low level. Upon any key press or
upon last key press, the LED will do 10 Quick Blinks to indicate low power.
