Volume settings
The microphone and loudspeaker settings are fac-
tory set, and do not usually need changing. It may
be necessary to change the settings when using
certain mobile telephones in the following situa-
tions:
– If the person you are talking to cannot hear you
loudly enough (increase value for "Mic volume").
– The person you are speaking to hears his voice
echoing (decrease the CDR-31 volume or de-
crease the "Mic volume" value).
– The handsfree unit produces a distorted sound
(decrease the "Call volume" value).
Recommendation
Only ever increase or decrease one of the two val-
ues at a time, and only by one level.
