What to do if the red LED glows on my Hytera PS22002 Power Supply?
- E
  Elizabeth MayAug 5, 2025
  If the red LED is glowing on your Hytera Power Supply, it could be due to several reasons: * In battery mode, the battery runs low, has a voltage less than 10.8V, or the voltage is above 10.8V while its capacity is small. In these cases, restore the mains supply or replace the battery. * The fuse of the AC power port may be blown, so replace the fuse. * There may be an overload or short circuit, so diagnose the failure and settle the trouble. * The battery might be damaged or its life has expired. Replace the battery. * The relay is locked. Restore the mains supply, connect the battery again, and if needed, replace the battery. * In battery mode, big current causes the battery voltage to fall below 10.8V. Replace the battery.
