 Using Your Phone

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.
