4 Operating Notes

Your HEARO 888 DIGITAL is a radio frequency device that conforms to the strict European and FCC stan- dards. For physical reasons that are not related to the quality of the product, extremely strong interfer- ence sources may affect reception. In order to maintain interference-free listening pleasure, do not oper- ate your HEARO 888 DIGITAL in the close vicinity of radio equipment, cellular telephones, or directly above TV or computer monitor picture tubes. The supplied connecting cables are long enough to allow the transmitter to be placed at a safe distance from interference sources.

Reflections off metal surfaces may reduce the range of your transmitter. Therefore, be sure to place the transmitter at least 8 inches (20 cm) away from any kind of metal surface.

Operating switches on or connecting the transmitter to your audio source may cause clicks which at high volume settings may affect your hearing. Therefore, be sure to set the VOLUME control on the head- phones to minimum before switching between different sources (tuner, turntable, CD player, etc.) or con- necting the transmitter.
