• Only for transmitters containing a NiMH rechargeable battery 
• Separate charging of each rechargeable battery 
• Status display via LEDs 
• Maximum charging time 2 hours 
• No memory effect due to a microcontroller monitoring the battery voltage during the complete charging time 
• Supervision of voltage gradient and disconnection of delta U 
• Significance levels are integrated such as dU-recognition, supervision of voltage gradient and safety timer
