• High Power Output: 10W power for extended range and strong signal penetration.
• Dual Band (UHF/VHF): Supports both Ultra High Frequency (UHF: 400-490MHz) and Very High Frequency (VHF: 136-174MHz) for versatile use.
• High Definition Sound: Ensures clear and crisp audio transmission and reception.
• Type-C Charging: Modern and convenient charging interface.
• Durable and Drop Resistant: Built to withstand demanding environments.
• Dual Screen Display: Provides comprehensive information at a glance, supporting duplex transmission and reception.

3.3. Dual Mode Intercom: Public Network (4G LTE) vs. Simulation (Analog)

The 5288 Plus offers unparalleled flexibility by integrating two distinct communication modes:

• Public Network (4G LTE PoC): Utilizes cellular networks for unlimited nationwide coverage. Ideal for long-distance communication where cellular service is available.
• Simulation (Analog Radio): Operates on traditional UHF/VHF frequencies. Best for local, direct radio-to-radio communication, especially in areas without cellular coverage.

3.4. Dual Screen Display

The radio features a dual screen display for enhanced usability and information access:

• Duplex Transmission and Reception: Allows for simultaneous transmission and reception, similar to a phone call, in certain modes.
• Dual PTT Transmission Button: Enables easy switching or management of two separate communication channels.

4. Setup

4.1. Charging the Battery

Before initial use, fully charge the radio's battery. The 5288 Plus is equipped with an 8800mAh large capacity lithium battery and a convenient Type-C charging port.
