Zoom H1n Firmware 1.21

Improved SD card handling during high-write activities. Fixed rare issue where recording would stop unexpectedly when battery voltage fluctuates.

Under firmware 1.20, some units would show two bars of battery remaining, then abruptly shut down without warning when using alkaline AAs. Version 1.21 adjusts the voltage threshold for the battery icon. While it doesn’t extend battery life, it provides a more accurate depletion curve, giving you a true 15-minute warning before shutdown instead of a sudden death. zoom h1n firmware 1.21
