Page 4: Introduction
A local telephone company may make changes in its communications facilities or procedure. If these changes could reasonably be expected to affect the use of the GX500 or compatibility with the network, the telephone company is required to give advanced written notice to the user, allowing the user to take appropriate steps to maintain telephone service.
Page 5 The pictures in this manual are for illustrative purposes only; your actual hardware may look slightly different. 1.2.7 Interference and Attenuation An GX500 may interfere with sensitive laboratory equipment, medical equipment, etc. Interference from unsuppressed engines or electric motors may cause problems.
