1. Radio Comfort Digisystem relies on radio technology to transfer the sound between transmitters and receivers. Like all radio systems, it communicates on specific channels. If you use two transmitters on the same channel, or neighbouring ones, there may be interference. Other electronic equipment can also interfere with radio transmissions. Channel planning To achieve optimal radio performance you need to take into account the distance between transmitters and their frequencies.
2. Battery maintenance This product has a built in Lithium-Ion Polymer battery. Lithium-Ion batteries do not suffer from so called memory effects and do not need to be routinely discharged to preserve performance. The battery's capacity will degrade over time. This is normal for all rechargeable batteries. Battery lifetime is dependent on usage patterns. The battery is preferably charged little and often; it will reach 90% of its capacity after half its charging time.
3. Troubleshooting Consult the following guide if you have problems with your equipment. If you still have questions, please contact your point of purchase.
