v1.4.0.3

This version further enhances the ECG recording experience, particularly in situations with challenging electrode contact or external interference, and improves the accuracy of display and charging information for consistently reliable device operation.

Key Features

The detection of suboptimal electrode contact has been refined, reducing unnecessary notifications previously caused by signal fluctuations in two ECG channels.

Stability & Reliability Enhancements ​

Enhanced charging and battery status display
The charge status shown after completing a recording has been optimized for greater accuracy.
The battery level displayed when starting the device now consistently reflects the actual capacity.

Improved ECG signal quality
Isolated signal spikes have been minimized, resulting in a smoother and more stable, artifact-reduced recording.

v1.3.0.20

This release further improves device reliability, recording performance, and power-state behavior, while introducing several optimizations for smoother everyday use.

Key Features

Improved USB performance and startup reliability
Devices now start reliably even under low battery conditions.
Fixed rare cases where the device could become unresponsive during startup or recording initiation.

Optimized shutdown behavior
The device now consistently enters deep-sleep mode in low-battery scenarios.
Eliminated rare startup freezes related to shutdown handling.
Improved LED behavior when the device is placed in the docking station shortly before shutdown.

v1.2.1.31

This release focuses on improving recording reliability, system stability, and operational transparency.

Key Features

Premature termination of recording due to a high accumulation of detected pacemaker pulses is prevented.

The shutdown process of the recorder after removal from the docking station has been improved.

Logging of recorder statuses has been expanded for better traceability.

Bug fixes, performance and stability improvements.

v1.2.0.5

This release introduces improvements to recording workflow behavior, charging status indication, and signal quality handling.

Key Features

The 8 minutes auto start timer is re-triggered when a lead-off condition occurs in hookup mode. This allows for the closed-lead condition to be re-established within the next 8 minutes.

The Max-LED indicates the "full charge status" when the charge for the current set maximum duration has been reached. Charging continues in the background until the battery is full.

Signal quality on channels affected by open electrodes has been improved.

The shutdown process of the recorder after recording completion has been improved.

Bug fixes, performance and stability improvements.
