[Warning]
The RF553A remote control is a low power RF device with an audit
certificate. Without approval, the company, firm, or user shall not
change the frequency, increase the power, or change the
characteristics and functions of the original design. The use of
low power RF equipment shall not affect flight safety or interfere
with legal communication. If any interference is found, it shall be
stopped immediately and improved to no interference before
continuing to use. The aforementioned legal communications refer to
radio communications operated in accordance with the provisions of
the Telecommunications Administration Act. Low power RF equipment
must withstand interference from legitimate communication or
industrial, scientific, and medical electromagnetic radiation
electrical equipment.
FCC:
This device complies with part 15 of the FCC Rules. Operation is
subject to the following two conditions: (1) This device may not
cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause
undesired operation.
Changes or modifications not expressly approved by the party
responsible for compliance could void the user’s authority to
operate the equipment.

– Transmit the code by BLE(Except Power key code) [BLE disconnected status] – Transmit the code by IR [Note] – If key events occur the RCU must send the key code(*1) [Operation] – Press and hold [RED] and [BLUE] key for 5 seconds [When Forced IR] [Google Assistant] : BLE send other Buttons : IR send [LED behavior] – LED keep to light up fast blink 9 times when converting completion [BLE recovery] – Method1: [RED] and [BLUE] key for 5 seconds Method2: Battery reset Method3: Unpairing If the RCU is in a low power state, it will shut down directly without warning (warning=LED blink). V_shutdown = 1.9V V_recovery = 2.3V – The voltage is checked once every 8 seconds for 30 seconds after the button is pressed. – If the button is pressed again within 30 seconds, the time is extended by 30 seconds. – For the rest of the time, the voltage is checked once an hour. – The value of remaining voltage is kept at the lowest value. – If the lowest value is updated, it will be sent to the TV side. – Voltage detection is not done while the button is pressed or when IR is transmitted. – The remaining voltage will be initialized under the following conditions. (1) When the battery is removed or inserted (Hardware reset) (2) After pairing. (3) When the status is changed from deep sleep to wake.
