Read and adhere to the following instructions and warnings.
SECURITY
We recommend that the user creates strong password for their
mobile device, to avoid illegal intrusion of equipment.

time.

the App store (for iphone) at any time.
Do not install Apps on hacked, jailbroken, or tampered phones.
If the mobile device cannot control the wheelchair correctly, please
stop use of the mobile device and use the joystick on the wheelchair
immediately. Please remove other wireless devices from the
environment, and connect the mobile device to the wheelchair
again. Try controlling the wheelchair with mobile device. Do not use
the mobile device until it can control the unit correctly.
When using the mobile phone, try to keep other wireless devices
away from the wheelchair, at least 10' away.
At the application layer, AES128 is used to re-encrypt the interactive data by
hardware. The 128-bit initial password will be calculated by the feature code of
the interactive parties according to the algorithm, and will be continuously
updated and synchronized during the connection process. Since there are
dynamic random change codes and sequence codes in the data, the actual data
sequence of each communication is changing, and the real data will be seen
after decryption. If the data is incorrect or the content verification is illegal
several times, the connection will be interrupted and the blacklist will be added
at the same time, until the coverage can be removed. Ensure that the signal is
transmitted as expected.
