Voice Transmission
A ROLMphone speakerphone only allows voice
transmission in one direction at a time. Therefore, you
and the other party cannot talk simultaneously. Also,
if you are speaking you may not hear voice interrup-
tions or background noise, but this does not mean
your call has been disconnected.
If the noise level in your room is high, or the other
party is speaking too softly, you can increase the other
party’s voice volume by pressing the Volume Up ▲
key. If the other party’s voice is too loud, you can in-
crease your ability to interrupt by pressing the
Volume Down ▼ key. If the volume adjustment
cannot compensate for the high noise level, you can
use the handset to continue the conversation.
Since the speakerphone’s microphone is located
underneath the right front side of the telephone,
objects need to be kept away from that area to ensure
clear transmission. Also, if your telephone is near a
large object that reflects sound and you are further
away from the telephone than the object is, your voice
volume may be reduced and your voice may sound
hollow to the other party. However, the party should
still be able to understand you.
