UHF 403–470 MHz

The AC146U502-MOT-NA operates across:

403–470 MHz UHF

This broad UHF frequency coverage makes the EVX-S24 suitable for properly licensed commercial UHF communications systems operating within its supported frequency range.

UHF portable radios are commonly used in applications such as:

• Hospitality

• Hotels and resorts

• Retail

• Restaurants

• Warehousing

• Manufacturing

• Education

• Schools and campuses

• Security

• Property management

• Maintenance

• Healthcare facilities

• Commercial buildings

• Event operations

Radio frequencies and system parameters must be properly programmed for the customer's authorized communications system.

Analog & Digital Operation

The EVX-S24 supports:

Analog + Digital Communications

This allows organizations to maintain compatibility with supported analog radio systems while transitioning toward digital communications.

Mixed-mode operation can be particularly useful for businesses upgrading an existing fleet over time rather than replacing every radio simultaneously.

RF Output Power

Motorola specifies selectable output levels of:

Digital: 3W / 2W / 1W / 0.5W

Analog: 2W / 1W / 0.5W

This allows the radio to be configured according to the requirements of the communications system and operating environment.

Actual communication range depends on buildings, terrain, interference, antenna selection, radio programming, repeater infrastructure, and other environmental factors.

256-Channel Capacity

The EVX-S24 supports:

256 Channels

organized into:

16 Groups

This substantial channel capacity allows organizations to create separate communications channels for different departments, locations, teams, shifts, or operational requirements.

8-Character Display

The EVX-S24 features an:

8-Character Alphanumeric Display

The display provides convenient visual information while retaining the compact dimensions of the radio.

Users can quickly identify programmed channels and access supported radio functions without requiring a large or bulky display.

Four Programmable Keys

The EVX-S24 provides:

4 Programmable Keys

These include three front-mounted programmable controls and one programmable side control.

The buttons can be configured for supported functions according to the organization's operational requirements.

Compact & Lightweight Design

One of the major advantages of the EVX-S24 is its compact form factor.

With the standard battery installed, Motorola specifies dimensions of approximately:

3.58 × 2.17 × 1.24 Inches

and a weight of approximately:

7.6 oz

This makes the EVX-S24 particularly useful for employees who need to carry a radio throughout an entire work shift without the bulk of a larger commercial portable.

IP67 Protection

The EVX-S24 carries an:

IP67 Rating

The rugged housing is designed to provide strong protection against dust and water exposure.

This makes the EVX-S24 suitable for demanding professional environments where portable communications equipment may encounter moisture, dust, spills, or harsh working conditions.

Emergency Alert

The EVX-S24 supports:

Emergency Alert

When properly programmed, this provides users with quick access to supported emergency communications functionality.

Lone Worker Alert

The radio also supports:

Lone Worker Alert

This feature can provide an additional layer of safety for employees who work independently or away from other personnel.

Feature operation depends on radio programming and system configuration.

Digital Calling

Supported digital functionality includes:

• Individual Call

• Group Call

• All Call

• Digital Radio Check

• Call Alert

• Digital Emergency

• Radio Enable / Disable

• Remote Monitor

• Call History

• Text Messaging

Feature availability depends on radio programming and system configuration.

Dual Capacity Direct Mode

The EVX-S24 supports:

Dual Capacity Direct Mode

This digital capability can provide two communication paths on a compatible 12.5 kHz frequency without requiring repeater infrastructure.

Site Search

The EVX-S24 supports:

Site Search

For appropriately configured multi-site systems, Site Search allows the radio to identify and move to the programmed site providing the strongest available signal.

This can be useful for organizations operating across large properties, multiple buildings, or multi-floor facilities.

Digital Privacy

The EVX-S24 supports:

Basic and Enhanced Privacy

for compatible digital communications.

Availability and configuration depend on the radio system and programming.

Analog Signaling

For compatibility with conventional analog radio systems, the EVX-S24 supports a range of signaling technologies including:

• CTCSS / DCS Encode and Decode

• MDC1200

• 2-Tone

• 5-Tone

• DTMF

• FleetSync ANI

• ARTS

This makes the EVX-S24 flexible when integrating with supported existing commercial radio fleets.

Battery

The standard configuration uses a:

2300 mAh Li-Ion Battery

Motorola specifies estimated battery life of approximately:

12 Hours – Digital at 3W

11 Hours – Analog at 2W

Actual battery performance varies according to transmit activity, power level, signal conditions, battery condition, radio programming, temperature, and other operating factors.

Standard Package

The standard EVX-S24 package includes:

• Motorola Solutions EVX-S24 UHF Portable Radio

• 2300 mAh Li-Ion Battery

• Compatible UHF Antenna

• Charging Equipment

• Belt Clip

• Standard 3-Year Warranty

The current Motorola catalog identifies the PMNN4468 2300 mAh Li-Ion battery as the standard battery option for this configuration.

Antenna selection may vary according to the customer's programmed operating frequencies.

Package contents should always be verified at the time of purchase.

Black vs. Yellow Models

The EVX-S24 is available in two housing colors:

AC146U502-MOT-NA = Black

AC146U512-MOT-NA = Yellow

Both configurations provide the same basic 403–470 MHz UHF frequency coverage, 256-channel capacity, and analog/digital communications capabilities.

The primary difference between these two model numbers is the housing color.

Important

The AC146U502-MOT-NA is the:

Black / UHF 403–470 MHz / 256-Channel / Analog & Digital EVX-S24

This model should not be confused with:

AC146U512-MOT-NA – Yellow EVX-S24

Radio programming is required before operation.

Operating frequencies and system parameters must be properly configured for the customer's communications system.

FCC licensing may be required depending on the frequencies and application in which the radio is used.
