Conducting a call
Push-to –talk
When operating in a noisy environment, it can be conveniet to
controll own microphone, so noise and disturbing sounds will not
affect the hands-free switching. When a call is started in hands-free,
it can be turned into push-to-talk by pressing the push-to-talk
key, and hands-free can be regained by giving the push-to-talk key
a shor push. The display will show the mode currently in use.
Transfer
A conversation can be transferred between the conversation
handset
modes, using either hands-free, push-to-talk, headset or handset.
headst
The principle is that the last active device is the one beeing used.
hands-free
For switching from headset or handset to hands-free it is neccesary
to pass via push-to-talk mode by first pressing the push-to-talk key
and after that entering hands-free by giving the push-to-talk key a
short push. This is because when in conversation, pressing the
hands-free key means terminating the call.
Headset
When a headset is connected having a push-to-talk button, a call
push-to-talk
can be received and accepted by pressing the push-to-talk button
of the headset. A short activation of the headset push-to-talk will
turn the headset conversation into full duplex.
Headset connector
With the SC421 a headset can be connected using a water tight connector set. The
connector allows for removing the headset when not in use.
The connector is
NOT
water tight when left open, so it is important to mount the cover
properly when the headset is removed, in order to leave it tight and closed for mositure.
Failure to do so will reduce lifetime.
