Menu items
1. TALK MODE: Every kind of communication is viable between devices whose ‘TALK MODE’ and
‘CHANNEL’ match each other. Hi-fi half and hi-fi full are high-quality voice modes that are best used for
short-range communications.
Half-duplex -> Not available for simultaneous ‘transmit’ & ‘receive’ functions. Talking and listening
available by taking turns. It works in the same way as other typical radios. Only one radio in the group
is allowed to talk.
Full-duplex -> Available for simultaneous ‘transmit’ & ‘receive’ functions. Able to listen while talking.
Two radios in the group are allowed to talk at the same time.
Tri full-duplex -> Available for three-way simultaneous ‘transmit’ & ‘receive’ functions. Three radios in
the group are allowed to talk at the same time.
Hi-fi half -> Using the same communication method as the half-duplex mode, this mode allows for
high-quality voice communications.
Hi-fi full -> Using the same communication method as the full-duplex mode, this mode allows for
high-quality voice communications.
2. CHANNEL: Every kind of communication is viable between devices with a ‘TALK MODE’ and ‘CHANNEL’
that match each other.
3. GROUP: If the line is mixed up or the ‘CHANNEL’ is already taken by other people, set the ‘GROUP’. By
doing so, communication becomes viable between devices whose ‘GROUP’ matches each other.
4. PTT/VOX: Voice communication can be sent while pushing the PTT button. And, the radio will
recognize your voice and then send it automatically. ‘VOX’ sends all of the voices that it recognizes.
5. VOX LEVEL: The ‘VOX LEVEL’ enables you to control the sensitivity levels of recognized voices when
the ‘VOX’ function is turned on.
6. EMERGENCY: ‘EMERGENCY CALL’ is a function to make a call in an emergency. For example, if you are
in an emergency, this function helps you send an emergency call to others on a regular basis, no matter
which channel is being used. Those who receive the signal can respond to you through the ROLLTS
DOMINO.
send(or to receive) an emergency call, push the menu button and the volume buttons (
‘-’ or ‘+’) simultaneously.
7. ENCRYPTION: You can talk with people only if their encryption code is identical to yours.
8. SIDE TONE: With the ‘SIDE TONE’ on, a voice message can be heard through the earset, making it
possible for you to check if it has been sent.
9. MIC GAIN: The MIC GAIN allows you to adjust the microphone volume.
10. ROGER BEEP: Setting the "ROGER BEEP" value to "On" generates a beep at the end of each reception.
11. RF POWER: The RF POWER allows you to adjust the strength of the transmission signal.
12. FEC: Forward Error Correction (FEC) is a technique used for automatically correcting lost portions of
the transmission signal.
13. DEFAULT SET: All of the values that have been tuned or changed to meet the needs of the user will
be returned to their default settings.
14. VERSION: It is used to check the version of your product.
15. SERIAL NO: It is used to check the ID number of your product.

⑦ Encryption: AES-256
⑧ Frequency hopping: 902-928 MHz ISM band, 50 channels, 1,000 groups/channel
<NOTE>
① The maximum range is 2 km with a clear line of sight. The indoor range may be less if there are any
obstacles, such as steel or concrete structures.
② The ‘Stand-by’ features our unique low-power technology. It can remain on standby for the maximum
hour.
③ The ‘Talk time’ features our unique low-power technology. Based on the estimated standard usage
(5:5:90, i.e., a usage ratio of 5% reception, 5% transmission and 90% standby), it can be used for the
maximum hour.
④ Frequency hopping applied ROLLTS DOMINO ensures clearer and more secure communication by
eliminating any frequency interference between systems. (The radio transmits a limited number of data
packets over multiple channels and hops through each in a set pattern.)
