Professional Walkie Talkie refers to those Walkie Talkies that their transmit power is 4-5w, their power ranges are 136-174MHz or 400-480MHz. Also this Walkie Talkie is usually at a more far communicating distance of 3-8km (changes as the different environment). They feature an easy operation since most professional Walkie Talkies don't come with digital keyboards but only with two knobs to control number of channels, power source and switch. The deficiencies of professional Walkie Talkies is much bigger in size and weight, but much superior in waterproof, anti-shock, anti-fall and anti-aging aspects, and the performances are more stable. Usually, they are widely used in constructional engineering, property management, factories.

FAQ
1. Why I can't hear from the earphone when the indicators flash green?
There may be poor contact between earphone and earphone jack. Please pull out the earphone and plug in again.
2. Why the radios transmit only?
Check if PTT is blocked with something. There should be slight "dadada" at the pressing of PTT.
3. I can't turn on the radio and even it is turned on, it often shuts off aautomatically. Why?
Please check if the battery contact is out of shape. Or make sure the switch is not loosened.
4. Why my voice received is low?
Please check if the MIC is blocked by something. And make sure that the volume is turned high.
5. What should I do, if the radio is dropped into water?
Take the radio out of water and remove the battery as quick as possible. Swing the water out of radio and put the radio at a dry and ventilated place. Return the radio to your HQT authorized dealer for maintenance as early as possible.
6. Why Couldn't I communicate with other group members?
First, please verify that the frequency point and the CTCSS you are using are the same as those of your group members. If the channel frequency and the CTCSS are the same, please verify that your group members are within radio communication range.
7. Why can I hear the voice from other groups?
Please change your CTCSS for the channel. At the same time, you also need to change the CTCSS for all the radios in your group. If you don't like this, you may switch to another channel.
8. After a period of time, my radio works well, but no sound from my earpiece.
The socket inside the radio has been damaged. Please return the radio to your HQT authorized dealer for maintenance.
9. Why is the radio communication range shorter than before and why the sensitivity becomes poorer?
Please check the antenna and make sure it is a good one. Also please check the antenna socket is not damaged or loosened. If so, please return the radio to your HQT authorized dealer for maintenance.
10. Solutions to FAQs when trying the radio- Frequency Interference: Voices from other group or other broadcasting stations are heard on the channel. Three methods are available: 1) Change Channel 2) Set CDCSS/CTCSS or DTMF code 3) Lower the squelch level.
- Short Distance: If there is difference between required communication distance and practical distance, the communication can be realized through adjustment of radio RF power or squelch level. Or, a repeater is suggested added to improve the communication.
- Intermittent Voice: Intermittent voice is often heard in critical distance during radio communication. Under such condition, please adjust squelch level or cancel CDCSS/CTCSS code to improve it.
- Squeaking: It's normal that squeaking may be heard on the channel when two radios is several meters near or closer. Users can adjust the volume to improve it.
