What does one-way radio mean?
Unidirectional or one-way radios allow a speaker or instructor to speak to a listener or student, who in turn cannot respond but can only listen. In this case, the RECEIVER is equipped with a headset, while the TRANSMITTER with a microphone.

What does two-way radio mean?
Bidirectional or 2-way radios allow a speaker or instructor to speak to the learner or student and vice versa. In this case, both the RECEIVER and the TRANSMITTER are equipped with a headset with a microphone.

How do I recharge my radios?
Our radios are sold with USB charging cables compatible with all the charging plugs in the market.
To recharge the battery of the TRANSMITTER and the RECEIVER you can use most standard plugs that you use daily for charging your smartphone or tablet of any kind and brand (Apple, Samsung or commercial).

To recharge the radio:

1. Turn off the radio (TRANSMITTER OR RECEIVER)
2. Connect the USB charging cable to both the RECEIVER/TRANSMITTER and to a source of electricity through a charging plug
3. The LED on the front of the radio (above the display for the WS2 model) turns red.
4. The radio is charged when the LED turns off.

As a source of energy, in addition to the standard outlets you can use the USB port of your car, scooter/bike or computer. In this case note that charging times may take longer. You can also use a POWER BANK (charging speeds vary based on its specifications).

How long does it take to recharge the battery?
The charging times vary and depend on the plug used. For fast charging, we recommend using a 1.5 or 2-amp plug of any brand. The charging time depends on the power (Amperage) of the Plug used.

To recharge quickly and comfortably up to 10 radios you can use our USB Multicharger. This accessory is lightweight and very small and allows you to quickly and simultaneously recharge up to 10 transmitters or receivers (compatible with mini sport and WS2 radio models).

If you need to charge more than 20 receivers you can buy a charging suitcase through which you can recharge and carry up to 56 radios, including accessories.

Mini Sport radio charging suitcases for 54 receivers plus 3 transmitters.

How do I understand when the radio is charged/depleted?
From radio on: The mini SPORT transmitter and the WS2 transmitter and receiver are equipped with displays. While turning on the radio (both receiver and transmitter) on the display at the top left, the battery icon appears with 3 even bars inside, each symbolizing 33% charge (totaling 100% when all three are displayed).

When the battery icon shows:

• 3 bars: battery charge level between 68% and 99%.
• 2 bars: battery charge level between 34% and 67%.
• 1 bar: battery charge level between 5%and 33%.

Radio off: All Whisper radios have an LED (on the front) indicating the battery level. On a low battery, the LED appears red. When the battery is 100% charged the LED will turn off.

What can I do when the receiver suffers from interference?
Our radios are designed to communicate on short-range frequency and generally do not suffer from interference from other radio systems.

However, in some cases where there may be other radios in use on the same channel, there may be bleed over. This can happen on a specific channel or sets of channels (frequency) on which your radio usually operates and someone else is occupying the same channel, or when there is slight interference from other transmissions (though this is not as common).
If this happens, simply change the channel to a different one on transmitters and receivers.

How can I sanitize the radios?
Radios can be sterilized with an alcohol-based towel or with any antibacterial or sanitation product available on the market.

Can I use two transmitters on the same channel within a 50-metre radius?
You cannot use (while on) two transmitters set on the same channel within a radius of 150 meters on mini SPORT radios and of 250 meters on the WS2.
The transmitters on the same channel create interference that inhibits their operation by preventing all receivers from working.

If there is a situation where all the receivers do not work, check that only one transmitter is on that channel.

How do I switch channels?
To switch channels, you must first unlock the radio.

1. Turn on the radio
2. Press the button with the LOCK icon 5 sec.
3. The LOCK icon disappears from the display
4. Use the UP ARROW and DOWN ARROW buttons to move between channels.

When the radio is tuned to the transmitter channel on the display at the top left, the reception icon appears.

How many channels do the radios have?
The mini SPORT model radio has 83 channels

How can I adjust the volume of my earbuds?
From “radio on”, you can adjust the volume to 9 levels.
Turn up the volume: From “locked radio” (lock icon visible on display) press the up arrow button until you reach the desired level.
Turn down the volume: From the “locked radio” (the lock icon visible on the display) press the down arrow button until it reaches the desired level.

For increased performance, we recommend that you make this and all other adjustments before using the radios. You should also test the systems prior to full use.

How do I adjust the volume of my microphone?
It is possible to adjust the volume of the microphone only on the TRANSMITTER.
This adjustment allows you to adjust the correct volume of the microphone when switching from a panoramic microphone (such as Ear-mic accessory or the Clip Light) to a directional microphone (such as the Helmet PRO, the Neck V4) so that the speaker’s or instructor’s voice arrives at the receiving radio with the optimal volume:

1. To adjust the volume of the microphone
2. Turn on the transmitter
3. Press the button with the LOCK icon 5 sec
4. The LOCK icon disappears from the display
5. Press the SET button to increase the volume level
6. Turn on a RECEIVER on the same channel as the transmitter you’re using to verify that the volume level of the earbuds is correct.

The microphone volume is set correctly when:

• Using the volume key (-) the receiver can mute it.
• The instructor’s voice is dominated by background and ambient noises.

What should I do when I don’t hear the speaker’s or instructor’s voice?
In most cases it is a problem due to an incorrect configuration of the channel on the receiver.

First, check if the receiver is synchronized on the same channel as the transmitter and that the volume is set to zero.

To check if the mini sports receiving radio is synchronized on the same channel as the transmitter

1. Turn on the TRANSMITTER
2. Turn on the RECEIVER
3. If the LED above the volume key (up arrow) is a BLUE color then the RECEIVER is connected to the TRANSMITTER, and check that the volume level is not zero
4. If the same LED is GREEN, the RECEIVER is not connected to the TRANSMITTER, and will sync again on the same channel as the TRANSMITTER
5. To synchronize the RECEIVER see the following question

How do I switch channels?
To receive the speaker’s or instructor’s voice, the RECEIVER must be set to the same channel(synchronized to) the TRANSMITTER.

When the RECEIVER is not connected to the transmitter, the LED above the volume key (up arrow) is GREEN. When it is synchronized, the LED light is BLUE.

To synchronize the RECEIVER with the TRANSMITTER:

1. Turn on the TRANSMITTER
2. Turn off the RECEIVER
3. From RECEIVER OFF, press on the black button under the volume button – down arrow – and holding the button, with the other hand turn on the RECEIVER.
4. The LED starts flashing with the sequence: GREEN COLOR > BLUE COLOR FLASHING > BLUE FIXED COLOR (it will take less than 10 sec. )
5. When the LED color is a STEADY blue, the RECEIVER will be connected to the TRANSMITTER
6. If the color of the LED is still GREEN repeat the procedure from step 1

Does the mini SPORT radio use Bluetooth technology?
No! The RECEIVER and TRANSMITTER run on radio frequency at 2.4Mhz. The mini SPORT RECEIVER is WIRELESS because it is worn directly on the ear without the need for a headset cable.
