30 TMAA10-02 Handset
The TMAA10-02 handset provides the user with privacy and also
improves the audio quality in noisy environments. The handset
uses a dynamic microphone capsule, therefore the radio control
head must support dynamic microphone operation. For example,
a TMAA02-06 (support kit for dynamic microphones) must be
fitted to control head TMAC20-0T.
When your radio receives a call and the handset is mounted in
its locking cradle, the radio unmutes and you can hear the call
from your radio’s internal speaker and from any connected
remote speaker.
If you remove the handset from its cradle when you receive a call,
the radio unmutes and you can hear the call from your radio’s
internal speaker, from any connected remote speaker and from the
handset earpiece.
Using private handset mode, the radios internal and external speakers
are muted and the call can only be heard from the handset earpiece.
