Handset / Headset / Speakerphone
The FeaturePhone 175 SD features a handset and speakerphone. Both
the handset and the speakerphone key control Hook contact. The
Handset controls Hook contact by a magnetic proximity detector
mounted inside the device-case below the cradle for the microphone
side of the handset. Inside the handset a small magnet is mounted that
allows the FeaturePhone 175 SD to detect whether the handset is lifted
from the phone or put down again.
The handset control takes precedence over the speakerphone. If the
handset is “off hook”, press the Speakerphone key to transfer the call to
the speakerphone. The display will show “
Speakerphone ON
”. Press
speakerphone key again to transfer the call back to the handset. The
display will show “
Speakerphone OFF
”. If the call is on “speakerphone”
and the handset is “off hook” then putting down the handset will end
the call.
An optional headset can be connected to the FeaturePhone 175 SD. The
headset and handset can be used interchangeably. If a headset is used
the Hook control function
key can be used for “On” and “Off”
hook.
