Features

DuraForce EX2 KC-S704

・High-speed and high-accuracy reading performance※1 enabled by a high-performance barcode reader function※2.

Equipped with a barcode reading app capable of fast, high-accuracy※1 scanning of barcodes and 2D codes※2. Like commercial barcode scanners, it features an LED aimer※2 to precisely target and reliably read barcodes. Additionally, it includes a ToF sensor to enhance scanning accuracy in low-light conditions.

・Robust against drops and impacts, enabling long-term, worry-free use even in harsh environments.

Complies with 21 test items of the U.S. Department of Defense's MIL-STD-810H standard※3, and also passes Kyocera's proprietary tumble drop tests, steel ball drop tests, and cleaning tests using foaming hand soap※4. Ensures reliable long-term use across diverse work environments.

・Battery usage (degradation) status can be checked, and battery replacement is possible without powering off the device.

Features a hot-swap compatible "battery replacement function" that allows one-touch battery removal and replacement without turning off the power※5, enabling extended use without interrupting work※6.

Additionally, it uses an intelligent battery that displays degradation status—based on charge/discharge cycles and other usage data—directly on the smartphone screen. By visualizing when battery replacement is recommended, users can plan ahead for spare batteries※7, improving efficiency in battery management when operating multiple devices.

・Reliability through domestic production and security support for long-term operation.

Planning, manufacturing, and repair support are all conducted in Japan. Supported by three OS version upgrades※8 and four years of security patch updates※9, ensuring safe and reliable use over an extended period.

・Supports peace of mind with post-call recording and automatic transcription features.

Equipped with comprehensive calling functions suited for business use. Includes a post-call recording function※10 that allows users to choose whether to record after a call ends. AI transcribes voice during calls or from recorded audio files. Processing occurs entirely on the device without using cloud services, ensuring secure and worry-free use※11.

・Smooth, comfortable performance for business tasks thanks to large 8GB memory and virtual memory function. Delivers stable performance over long periods.

With 8GB of high-capacity memory and virtual memory functionality, multiple apps can run simultaneously with smooth, responsive performance. Even as memory demands increase over time due to app and OS updates, stable performance is maintained※12.

・Features designed for field operations, including dedicated buttons, Glove Touch®, and headphone jack.

Two dedicated direct buttons allow quick access to pre-set apps or answering incoming calls. Users can assign compatible apps as needed※13. Glove Touch functionality enables operation while wearing work gloves※14. To meet field requirements for reduced power consumption and minimized radio interference, a 3.5Φ headphone jack is included. This allows direct connection of wired headset intercoms, and two strap holes make it convenient for neck-wearing or preventing drops.

・Equipped with "Device Failure Diagnosis" app that enables self-diagnosis of device issues.

Includes Kyocera's "Device Failure Diagnosis" app※15, allowing users to perform simple self-checks when device performance seems suboptimal, supporting early issue detection and peace of mind.

・First smartphone in Japan※16 to support Wi-Fi HaLowTM (IEEE 802.11ah).

First smartphone in Japan※16 to feature Wi-Fi HaLow (IEEE 802.11ah), a new Wi-Fi® standard utilizing the 920MHz frequency band.

Even without conventional Wi-Fi networks or 4G/5G connectivity, the device can connect to Wi-Fi HaLow-compatible equipment or communicate directly between DuraForce EX2 units※17.

※2 Separate license purchase required in addition to device purchase to use the high-performance barcode reading function and LED aimer.

※3 [MIL Standard] Testing conducted on 21 items of the U.S. Department of Defense procurement standard (MIL-STD-810H): steel plate drop, shock, vibration, high-temperature operation (continuous), high-temperature operation (temperature change), dust resistance, rain exposure, water droplet (waterproof), saltwater spray, humidity, icing and condensation, icing and low-temperature rain, immersion, low-temperature operation, low-temperature storage, high-temperature storage (continuous), high-temperature storage (temperature change), temperature endurance/thermal shock, solar radiation, low-pressure operation, and low-pressure storage.

※4 Kyocera's proprietary durability tests include a tumble test (500 consecutive drops from approx. 1.0m height), a steel ball drop test (approx. 100g steel ball dropped from 1m height onto the center of the display), and a cleaning cycle test using foaming hand soap and foaming body wash. Performance claims are based on test conditions and do not guarantee operation under all real-world conditions. Does not guarantee damage- or fault-free use.

※5 To remove or replace the battery without turning off the power, select "Battery Replacement" from the menu shown by long-pressing the power button, confirm the instructions displayed on the device screen, and complete the replacement within 60 seconds. Data should be saved beforehand, as power may turn off depending on usage conditions.
