Like all wireless devices, your SurroundBar 4000 IHT may be susceptible

o RF interference from such sources as microwave ovens, WiFi computer

ystems, video game systems, cordless telephones, blue tooth systems, baby

onitors and other devices. In particular, any devices operating in the 2.4GHz

and may cause intermittent wireless connections between the SurroundBar

4000 speaker and the subwoofer. It is also possible that your SurroundBar 4000

IHT System may affect other wireless systems. For the most part, you can avoid

wireless performance problems by physically separating these devices from

your SurroundBar 4000 IHT System. Maintaining a distance of several feet

r more between your SurroundBar 4000 IHT speaker and any wireless device

hould prevent any mutual interference effects. If you do notice any subwoofer

ignal dropouts take care to identify the root cause (most commonly having

ther wireless devices too close) and resolve accordingly. Any interference

effects from a microwave oven will cease once the oven stops operating

and may be resolved on a long-term basis by increasing the physical distance

between your SurroundBar 4000 IHT System and the microwave oven.
