Adjusting the balance
The RS 4200 features a balance control for right/left volume adjustment. Use the balance control to adjust the volume so that you hear equally well with both ears.
Enhancing speech intelligibility
The button allows you to enhance speech intelligibility. If the speech is barely intelligible, press the button . The button is backlit in yellow and speech intelligibility is enhanced. Note: If the speech remains barely intelligible, increase the volume of your sound source.
Storing and charging the receiver
Do not store your receiver on a glass dummy head, chair armrest, or similar for long periods of time as this can reduce the contact pressure of the earbows. Furthermore, with the earbows pulled apart, the receiver remains switched on. After use, place the receiver into the transmitter�s charging compartment µ as shown on the left, without exerting too much pressure.
µ
If the receiver is placed correctly into the charging compartment, the LED lights up red: green: The rechargeable battery is being charged. The rechargeable battery is fully charged.
Before you use the rechargeable battery for the first time, charge it until the LED lights up green. This can take a maximum of 3 hours. With a fully charged battery, the operating time is approx. 9 hours. Note: Always store the receiver in the transmitter�s charging compartment µ to ensure that it is fully charged. The intelligent battery charging technology prevents overcharging. When not using the receiver for extended periods of time, charge the battery regularly every three months. 12
