QA:
Q: How do I program channels?
A: Program frequencies, tones, and channels effortlessly using the dedicated Android/iOS app via Bluetooth—no cables required. You can also set channels directly using the built-in keypad for maximum flexibility. [Play Store: HT /Apple App Store:BS-HT] 
Q: Does it support aviation communication?
A: Absolutely. Multi-band reception includes FM, Airband, VHF, and UHF, giving access to amateur radio, aviation, and emergency frequencies for versatile communication.
Q: How powerful is the DB50-B?
A: With up to 50W output, it delivers strong, stable signals across long distances—ideal for remote areas and off-road communication.
Q: Is it possible to connect the microphone to the unit wirelessly? I would like to put the box in the rear of my SUV and have the microphone only in the front row.
A: The Android HT APP available for the DB50-B supports the use of your smartphone mic. The IOS version does not yet support such. Besides those, hands-free sets with built-in microphones are also supported (but require the K2 BT PTT).
