Retekess TR110 Frequently Asked Questions

When using TR110, we always encounter various problems. See if there are any problems you encounter at this time?

1. The buttons do not work:

You can consider whether you accidentally pressed "LOCK" to lock the keys. In the power-on or power-off state, press and hold the "LOCK" button for 2 seconds and the screen will display the "key" symbol to lock all button function operations. Press and hold the "LOCK" button for 2 seconds again and the "key" symbol on the display will disappear, unlocking the key lock function.

2. The UHF band of the radio can no longer be accessed. It is bypassed and switched directly from UBD to WX:

You cannot switch by just pressing the "BAND" button. You need to tune to VHF first, and then press the "MODE" button continuously to switch to "UHF".

3. Does it support 1kHz frequency stepping in shortwave AM mode? Or is it just a general 5kHz stepping?

In the power-on state, short press the [STEP] key to set the step value.

AM frequency: 522-1710KHZ, step: 9.0KHZ, 3.0KHZ,

AM frequency: 520- 1710KHZ, step: 10.0KHZ, 5.0KHZ.

4. There is no sound in the LSB band of this product:

First, you can check whether the antenna is intact, and secondly, check whether there is interference from other signals in the environment of use. You can try it in another environment. At the same time, you need to pay attention to the time of listening to the single sideband. The single sideband communication is not like the traditional radio station that broadcasts 24 hours a day. Generally, it is easier to copy the signal when the communication is more frequent during the weekday evening or weekend morning and evening.

5. Can't get FM stations at all

① It may be that the battery is low after using it for a period of time. Try charging or changing a new battery. When the battery is low, it will affect the reception signal.

② Do not turn on the radio to listen to the radio while charging, which is easy to interfere with the signal.

③ Change the location and try swinging the antenna back and forth. If the sound is clear, it is caused by signal interference. Check whether there are more interference sources around than before.

6. What kind of external antenna can the TR110 radio use?

It cannot be connected externally.

7. (1) What can be heard in the aviation band?

① Approach control center: coordinate the landing order, direction, speed, and flight altitude of aircraft entering a certain airspace.

② Tower: mainly controls aircraft on the ground, allocates aircraft at the airport to take off, land, queue, etc.

③ Aircraft: you can only hear the conversation between the pilot of a specific aircraft and the tower and approach.

(2) You cannot hear the aviation band at the airport

You need to go near the airport. The conversation in the aviation band within 1 km is not like that in ordinary FM radio. There are always people talking or sounds. Many times, there is a blank background noise. There is sound only when there is a conversation. Be patient. The coverage area of the approach control center and the tower (compared to the aircraft) is smaller, but the frequency of conversation is relatively higher.

It is OK to not be so close to the airport, but it is best to ensure that you are within 30KM of the airport. You can basically hear the sound of the plane, but the frequency of conversation on the plane is generally very low, and you may not be able to hear any conversation even after waiting for a long time, so it is recommended to test and listen near the airport.

(3) Cannot search the aviation band at the airport

The airport has more than one frequency, you can try several.

There may be electromagnetic interference. You can go to an open place to stretch the antenna and try several channels to get the frequency as accurate as possible.

In the aviation band (AIR) reception state, press the "MODE" button to switch to the meter band. The frequencies are:

118.00MHZ, 123.00MHZ, 128.00MHZ, 133.00MHZ, 138.00MHZ.

8. Delete all stored radio stations with one click?

There is no such function.

9. Is the weather alert still effective when listening to different frequency bands?

It is only effective on specific bands.

The WX (North American National Weather Band) band has 7 fixed frequencies:

162.400MHZ, 162.4250MHZ, 162.4500MHZ, 162.4750MHZ, 162.5000MHZ, 162 .5250MHZ, 162.5500MHZ.

In WX mode, tap the "TUNE" key or rotate the shuttle to select the desired frequency. Press and hold the SET button to enter the ALERT warning mode, and the display will flash SCAN... When an alert signal is received, the alert receiving channel will be automatically activated. Press and hold SET again to cancel the alert receiving mode.

10. Can I preset or save channels and then scan them?

Yes.

11. How do I turn off sleep mode? How do I prevent the radio from automatically shutting down after a specified sleep time?

Time Status Press and hold the "POWER" button for two seconds to enter sleep mode. Short press the "POWER" button until the screen displays "10", and press the "POWER" button again to exit sleep mode.
