1. There is no display or something strange is displayed on my LCD? Why?

This could be a result of poor connection between the LCD and PCB, which could have occurred due to the radio being dropped and not being used properly.

 

2. The voice received on the radio is intermittent with rather big noises. Why?

When the radios are at the edge of the coverage area or in an area where radio signals are interrupted or blocked, these symptom will occur. If you are within your coverage area and there is no interruption to the radio signals.

 

3. How long is the communicate distance of T-XX?

The communication distance would be affected by following factors:

· Environment: If you use it around high buildings and large mansions, the communication range is smaller.

· Weather: If you use the radio on a rainy day, the radio performance maybe poor.

· Power: If the power of the radio is very low, you will have a poorer communication distance.

4. Why is the radio communication range shorter than before and why has the sensitivity become poor?

Please check the antenna making sure it is in good working condition, also check the antenna socket to ensure it is not damaged or loosened.

5. Once the radio has been programmed, why does the radio make noises like “dudududu”?

This noise often indicates the radio has been programmed incorrectly. The noise would be an indication the channel frequency programmed is out of the frequency range supported by the radio in question. 

6. Do YANTON radios have radiation and how do I use the radio safely while it works?

Radios radiate from their antenna at the RF frequency selected and the configured power level. In order to use the radio safely, hold the radio in a vertical position and keep about 2-5 centimetres distance from the radio. For more information about using a radio safely refer to the user manual for the radio in question.

 

7. Difficulty turning the radio on, and when it is turned on, it turns off automatically, Why?

If the battery on the radio is charged, check the battery contacts on the radio.

8. From the antennas YANTON provide which one is better, long or short antenna?

The short antenna is conveniently designed and easy to carry, the long antenna covers wider communication range. Selecting the right antenna is dependent on the environment you require coverage in.

 

9. My radio works well however there is no sound output when I use an earpiece?

The audio jack in the radio may have been damaged. Please return the radio to your YANTON dealer for maintenance.

 

10. What is the battery life cycle?

The Ni-MH battery is designed for 500 standard recharge & discharge cycles;  a Li-ion battery is designed for 1000 standard cycles. Replace your old battery when the battery life cycle is over allowing efficient performance from your radios.
