Frequently Asked Questions

What is the top concern when the commercial user chooses two-way radio?

As an essential communication tool, two-way radio is favored by business and commercial customers, such as supermarkets, hotels, and restaurants. 
Work staff often wear radios and use them frequently all day, running upstairs and downstairs to provide services. 
Therefore, when buying a radio, broader communication coverage, long-lasting battery life, and ease of carry are critical considerations.

Commercial users/staff often put the radio on the waist; it is easy to pull the cable and cause the earpiece to disconnect. How do we resolve this issue?

To solve the problem of earpiece disconnection, Hytera S1 and S1 pro adopt an innovative lock design. There is a minor groove in the earpiece connector. After inserting them into the radio jack, you need to rotate 90 degrees to lock them. In this way, even if you pull the cable hard, the earpiece is still secured to the radio and linked tightly together.

Audio quality is a critical factor in boosting the radio experience. Different scenarios require tailored solutions. Like a casino or shopping mall, in noisy surroundings, it is still difficult for the receiving party to hear even if you speak loudly. While inside luxury restaurants, you need to lower your voice to avoid disturbing customers. So, how does the S series take into account these extreme scenarios?

On a quiet night, the ambient sound is usually 25 decibels, which means this volume is very light. S1 pro supports whisper mode, which allows you to speak lightly at 25 decibels, and the receiving party can still hear clearly. Whisper mode is a quiet solution to Protect your privacy without disturbing the peace of customers around you.
The S1 Pro is also embedded with powerful AI-based noise cancellation to help you better filter the environmental noise and ensure a crystal clear voice.
It can accurately extract human voices from noise in milliseconds and remove unwanted background noise up to 30db, equivalent to directly turning down the noise volume. So even in disco, S1 pro can filter out most of the background noise, allowing the listener to hear more clearly.
The moment you press the PTT button; the noise cancellation effect is there.
 

Long-time wearing of an earpiece will cause ear pain and even irreversible damage, typically like hearing loss. How to protect commercial users/staff ears?

To eliminate ear pain, Hytera made three Ergonomic designs for the earpiece of the S series.
First, the earpiece is very light, only 10g. This earpiece adopts an auricle design. Unlike an in-ear earpiece that directly compresses the acoustic meatus, it hangs on the ear. 
In addition, we know the ears are sensitive parts of the body. The earpiece is designed with ultra-soft silicone and elastic and is a perfect fit for ear protection. 
Finally, the earpiece socket supports 180-degree rotation. You can adjust and switch to any ear. The perfect balance happens between work and rest for either ear.

Commercial users may need a lot of time to finish multi-server radio programming one by one, with low efficiency; how fast is this process?

Hytera S series radio supports innovative Air Clone technology based on BT; the one S series terminal data can be quickly synchronized to the same model over the air, realizing configuration copy and paste; it's done in seconds and one to many in a snap.

How could S1 and S1 Pro boost commercial users' service quality and image?

S1 and S1 Pro are famous for their excellent design (IF Design Award 2024).
They are free from superfluous details, resulting in a sleek, modern form. Smooth surface and fluid curves, making the S1 and S1 Pro affinity unsurpassed.
In addition, S1 and S1 Pro have two color choices: metallic gray and pearl white.
Pearl white shines like a pearl with a brilliant shimmer. The exquisite spraying technology lets you feel the art of light in your palm.
Metallic gray exudes a sense of calmness and firmness, making you confident to do your work better.
The S1 breaks with tradition by adding one more eye-catching front large PTT button. It blends classic radio elements with exquisite craftsmanship and forward fashion.
The S1 Pro is a digital radio. Its design concept comes from ancient Greek Doric order lines, exuding a solemn, stable, and majestic atmosphere. 
It strikes the perfect balance between elegance and performance and always gives your business a competitive edge.
