Built-in Scrambler

The scrambler feature provides enhanced security for your important public safety and private security communications.

Channel Annunciation

The feature enables radio to report the current channel number when power on or switching channel, offering you notable convenience.

Power on Self-Test

The radio itself checks radio status automatically when power on, and emits alert if an error occurs (e.g. CPU error or EEPROM error), allows the user to early detect unit faults.

Battery Power Indicator

Upon press the function key, the radio sounds"1", "2", "3", or "4" to indicate the current battery level of very low, low, satisfactory, or high respectively.

Embedded Message & Serial Number

The radio’s memory can store messages including service and programming records, for remarkable ease of maintenance and service; the feature also makes a unit identifiable by Serial Number.

Auto Contact

The feature is especially helpful in high-demanding communication environments, such as climbing, exploration, and rescue work. When feature enabled, the radio will automatically emit alert tone if the user is out of communication range.

Stun/Kill & Revive

Provides enhanced security to prevent unauthorized use of lost or rental units, by remote inhibition of either transmit or transmit/receive. A stunned radio will return to operational use after receiving the revive code.

2-Tone/5-Tone Encode & Decode

(Signalling system is radio dependent. 5-Tone models and 2-Tone models are available.)

ATEX (Atmospheres Explosibles) Directive 94/9/EC

Introduced in 2003, this is the European Union directive to which all two-way radios must conform if used in potentially explosive environments. It replaces the Cenelec classification in all European Union member states and EFTA countries. All HYT professional series ATEX portable radios are approved to ATEX Protection Class II 2 G EEx ib IIB T3 as interpreted in the following table:

Intrinsically Safe Classification

"Intrinsically Safe" is a fire safety rating given to the equipment by the Factory Mutual Research Corporation. When equipment is given this rating, it is considered safe to use the equipment in certain flammable or combustible atmospheres. Flammable atmospheres have been categorized by Class, Division, and Group as described below:
