HA-F834 Remote Control
1. Product Overview
This product is a wireless RF remote control (transmitter) operating in the
433 MHz band. It uses a surface acoustic resonator for frequency stabilization
combined with an advanced encoding IC, offering high frequency stability, low
power consumption, long transmission distance, and strong wall penetration.
This low-power remote control is suitable for short-range wireless control
applications.

4. Remote Control Instructions
This remote control can be paired with the HA-0806, HA-0807, or
HA-0808 series general purpose engine modules. After pairing, when the
module is connected to a 12 V power supply, it enters standby mode. When
the ON button on the remote control is pressed, a 433 MHz start signal is
transmitted via the high-frequency transmission circuit. The remote control
host receives this 433 MHz signal through its antenna; the microcontroller (CPU)
decodes and analyzes the signal. Upon recognizing a start command, the host
outputs a start signal and gradually rotates the stepper motor to open the air
door, then checks whether the gasoline generator has started successfully.
Conversely, when the OFF button on the remote control is pressed to send a
stop signal, and after confirming that the gasoline generator is running, the
microcontroller (CPU) outputs a stop signal to shut down the generator. The
stepper motor then rotates to close the air door.
5. Precautions
Do not use in a metal-shielded environment, as this may reduce the
remote control distance.
Avoid heavy pressure, dropping, or immersion in water.
If the remote control distance becomes noticeably shorter, check the
battery level or whether there is a strong interference source.

FCC Warning
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.
Any Changes or modifications not expressly approved by the party responsible for compliance could
void the user's authority to operate the equipment.
Note: This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates uses and can radiate
radio frequency energy and, if not installed and used in accordance with the instructions, may cause
harmful interference to radio communications. However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and on, the user is encouraged to try to
correct the interference by one or more of the following measures:
-Reorient or relocate the receiving antenna.
-Increase the separation between the equipment and receiver.
-Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
-Consult the dealer or an experienced radio/TV technician for help.
The device has been evaluated to meet general RF exposure requirement. The device can be used in
portable exposure condition without restriction.
