RS 165/175/185/195 red charging light is blinking very fast

A blinking charger light indicates a charging fault.

Possible causes

• Batteries not fully in place.
• Adjustable headband not fully closed, causing the earcups to hang unevenly.
• Batteries may not be working.
• A power surge or glitch in the charger.

What to do

1. Remove the batteries and reinsert them correctly (flat side facing the spring).
2. Gently rub the battery contacts with a pencil eraser to clean them.
3. Unplug the transmitter for 15 minutes, then plug it back in.
4. If the light still blinks, replace the batteries with new rechargeable NiMH AAA batteries (600–900 mAh).
