Transmitter battery monitoring. H.O.T. Ltd. strongly recommends to periodically check the peak voltage reached after a charge cycle completes (blue light off) using the charger supplied with above radios.
The on screen peak voltage displayed should be between 8.2-8.4V. Should the voltage displayed be below 8.2V you are advised to return the battery to your dealer if under warranty or replace the battery immediately.
Continuing to use your Transmitter without rectification could result in the battery PCM board shutting down before the Transmitter low voltage alarm sounds.
