Handset Modes
Standby mode (on-hook)
In standby mode, the handset is waiting for an incoming call or for the
user to place an outgoing call. The extension number is shown on the
display and there is no dial tone. In this mode, the handset is
conserving battery power and wireless LAN bandwidth.
When an incoming call arrives, the handset rings; the handset enters
the active mode and remains so until the call is ended. The call is
answered by pressing the START key, the Answ softkey, or the NavOK
key. The handset will ring according to user preference as specified in
the standby menus. The ringing can be silenced by pressing the END
key.
Active mode (off-hook)
To place or receive a call, press the START key. This transitions the
mobile handset to active off-hook mode. When there is a dial tone, the
handset is in communication with the PBX, and the display shows
information as it is received from the PBX. The user may place a call or
press a softkey or the FCN or LINE key to access additional operations.
To conserve these resources, return the handset to the standby mode
when a call is completed by pressing the END key.
Push-to-talk (PTT) mode
The NEC MH160 Wireless Handsets utilize channels for incoming and
outgoing radio communication. While PTT is active, the handset is in PTT
mode. It can receive regular phone calls in this mode. When a regular
phone call is answered, the handset enters active mode.
Configuration menu mode
When user preferences are being configured in the Config menu, the
handset is on but is not active. It cannot receive calls while in the Config
menu.
