METHOD 2:
If group selection is programmed as the primary function of the
ramp control,
select a group by pressing up or down, to scroll through the group list. The display
registers the new group name on line 2.

earlier. Use the
ramp control to scroll through different groups.
8.7 LAST SYSTEM/GROUP/CHANNEL RECALL
This feature, enabled through programming, allows the user to recall the last selected system/group after
an emergency or home function or system/group key function. For example, if the Home button (pre-
programmed) is pressed, the radio will go to the designated Home system/group or channel. If the Home
button is pressed again, the radio returns to the previous system/group or channel. At this time, the user
can toggle between the Home system/group or channel and the previous system/group or channel. The
operation is the same for the SG1-SG5 buttons.
8.8 DIGITAL VOICE OPERATION (PROVOICE)
8.8.1 Voice Modes
Each system (trunked or conventional) in the radio is programmed for no digital voice operation (analog
only) or digital voice format ProVoice. ProVoice programmed systems have three (3) different voice
modes: clear (analog), digital, and private. The voice modes are programmed on a per-group basis within
each trunked system and on a per-channel basis within each conventional system. A radio must be
equipped with the encrypt/decrypt option before it will operate in private mode.
Current ProVoice Conventional operation is for talk-around mode only.

8.8.2 Clear Modes
In Clear Mode, the radio transmits and receives only clear (analog) voice signals. These analog signals are
non-digitized and non-encrypted. Clear Mode transmissions can easily be monitored by unauthorized
persons. Groups or channels programmed for clear operation cannot transmit or receive unencrypted
digital or private messages.
