The following describes, in more detail, the available settings for each System Setup fi le tab item.
‘General’ Tab
GPS Mode Allows you to choose between three operating modes:
Normal: with the GPS receiver On.
Battery Saver: with a less frequent satellite signal updating process to conserve battery power.
GPS Off: allows you to operate the StreetPilot III indoors, which saves even more battery power
since the unit is not receiving satellite information. The ‘Use Indoors’ option on the Map page
options menu sets the operating mode to ‘GPS Off’.
Units
Allows you to select the desired units of measure for distance in miles (‘Statute’) or kilometers
(‘Metric’). If you select ‘Statute’, the speed will be shown in miles per hour and the elevation will be
shown in feet.
Voice
This setting determines when the voice (and chime, if enabled) sounds. The StreetPilot III will
“speak” status messages (if enabled), such as “external power lost”, and route navigation messages, such
as “drive point eight miles west and turn right”. If enabled, a single chime will precede all automatic
voice navigation messages (see ‘Attention Tone’ below). There are three possible voice messages per
route leg. The fi rst one comes right after you have completed a turn and are starting a new leg: the
voice message will be preceded by a lower pitched tone. The second message will come toward the
end of the leg depending on how fast you are progressing: this message is also preceded by a lower
pitched tone. The last message on the route leg comes right before a turn and is preceded by a higher
pitched tone.
By selecting “SPEAK Key Only” on the ‘General’ tab
under the ‘Voice’ function, the unit will only talk when
the SPEAK key is pressed.
The ‘Attention Tone’ fi eld determines whether voice
prompts are preceded by a chime.
