Easy to Use

FM540 with compact size is flexible to install in the vehiclewhen space is limited.FM540 provides a large 42x20mm dotmatrix and 4-line display, which allows the drivers to seeimportant information at a glance even under sunlight;3 programmable buttons can be programmed with manyfunctions, providing one touch operation including power levelswitch, emergency, scan, and so on.

Reliable Design

It is designed compliant with MIL-810C/D/E/F, ensuringoutstanding performance even under harsh environments.

Higher Spectrum Efficiency

Benefiting from 6.25K FDMA technology, FM540 creates twooffset 6.25 kHz channels in a 12.5 kHz spacing, increasingspectrum efficiency and reducing cost on adding frequenciesto support applications.

Superior Audio Quality

By application of FEC technology, FM540 effectively rejectsnoise, providing superior voice clarity in noisy environments orat the edge of the coverage area.

Secured Communication

Information privacy is important to your business.Communication is easily eavesdropped by unwanted listenersoutside the working team when you are using the analog radio.Kirisun FM540 series with 32-bits encryption technology canprovide more than 4 billion customizable codes, which meansthere is scarce chance that other users can monitor yourcommunication.

Easy Migration

The radio can provide analog mode, digital mode and mixedmode in channel configuration. Additionally, it supportsand DTMF encode and decode in analog mode, thus it meansyou can flexibly choose to migrate at your own pace.

Versatile Voice Call & Data Services

Using digital signaling, FM540 provides various voicetypes, including private call, group call, all call and emergencycall as well as remote control call and data service.
