1. If the system stops communicating during use, it is recoverable by turning off and on again.
2. I/O cable is less than 3meters.
3. The system is powered by internal battery only.
Electromagnetic Interference
Wireless communications equipment such as wireless home network devices,
mobile phones, and cordless telephones and their base stations can affect
leva PDHS. Keep leva PDHS away from other wireless equipment based on
the table below:
