Vertical Communications GCA70-248 - Manual (Page 86)

· Place the telephone on a hard surface and away from table edges. Do not
place the telephone in corners or enclosures. Do not let obstructions come
between you and the microphone. Rooms with hard, flat surfaces that reflect
sound may affect the sound-activated switches.
· If you are using a handset and the other party is using a speakerphone, avoid
breathing heavily into your microphone. Avoid other sounds that may affect
the distant telephone’s sound-activated switches.
· In some situations, such as when either you or the distant party are in a noisy
environment, you may have to lift your handset to ensure a clear conversa-
tion.
· When both you and the distant party use speakerphones, the sound-activated
switches can occasionally detect both voices simultaneously, thus blocking
out both voices.
