Solid red during charging. Solid Green when fully charged.

 

Charging process 

takes about 5 hours. (Using battery 1.2V 2100mAH. Transmitter refers to indicator.) 

4. The power sharing allows series connection for simultaneous charging of max 6 transmitters. 

Both chargers’ power status can be read by individual indicator

 

or

 

 on the master unit, 

which turns on if connected. Connect up to 3 bases to one power supply. 

5. This charger adopts intelligent compensation charging/control circuit for output-short 

prevention and user-friendly operation. 

Note

 

If the red LED doesn't light up or keeps flashing during the charging process, it indicates the 
charging contacts error, the battery quality is poor, or has an output short. Please reposition the 
transmitter or replace the batteries with new ones and ensure the correct connection between 
the charger and transmitter and then restart the charging process.
