FAQ

Q1: Can I power the VTX without an antenna?
No. Always install the antenna before powering on to avoid damaging the transmitter.

Q2: Why does the device get hot during operation?
High output power generates heat. This is normal. The built-in cooling system ensures safe operation.

Q3: Can I remove the housing for installation?
Yes, but heat dissipation will be reduced, which may slightly lower transmission power.

Q4: How do I match the receiver?
Ensure both transmitter and receiver are set to the same frequency and channel.

Q5: What happens if I exceed the input voltage?
Operating outside 24–36V may damage the device and void warranty.

Safety Notes

• Always connect the antenna before powering on.
• Do not touch the device during operation to avoid burns.
• Ensure proper ventilation for heat dissipation.
• Use only within the specified voltage range (24–36V).
• Select appropriate frequency channels to avoid interference.
