TP620Rugged Design

TP620 is strictly designed to meet IP67 and MIL-810C/D/E/F/G standards, ensuring good performance in harsh environments such as harbors, manufacturing plants and construction sites. 

TP620Durable Battery

A two-timeslot transmission reduces transmission times by half and thus increases talk time. A 2000mAh battery supplied as standard and provides at least 14 continuous working hours in analog mode and 16 hours in digital mode.

TP620Improved Audio Quality

Digital error-correction technology rejects noise and static, providing consistent audio quality throughout the coverage area and in challenging low lying areas. AMBE+2TM vocoder further improves speech communication. A 1.6W audio output and a 40mm diameter powerful speaker ensures louder and crisper voice communication.

TP620Double Capacity Repeater Mode

TP620 can work with a single repeater to achieve twice the traffic capacity without relicensing or rebanding, thereby offering two voice communications or one voice communication and one data transmission at the same time on a single channel.

TP620Analog/Digital Mode

TP620 can operate both in analog and digital mode by channel switching or mixed-mode scanning. TP620 can be used on the existing analog system, and when the budget allows, can easily transition to digital.

TP620Versatile Services

TP620 provides versatility, including individual calls, all call, group call, emergency call, radio enable & disable decode, remote monitor decode, radio check decode and call alert decode, thus facilitating highly efficient communication and management.

TP620Text Message

When it is not convenient to have voice communication, text messaging offers a silent communication option. You can choose one of the maximum 50 preset messages or do free-text via the keypad.

TP620Basic Encryption

The 16-bit digital encryption technology ensures only the intended person can hear the communication.

TP620One Touch Access

One-touch access is supported, to allow the making of a digital call or the sending of a message, providing a quick way to make a call or send a message in an emergency situation.

TP620DTMF Encode and Decode

Supports DTMF encode and decode in analog mode, providing better compatibility with existing analog radio system.
