Garmin NavTalk Owner's Manual page 25

The NavTalk' s three-level backlighting is controlled
with the PWR key, and may be adjusted at any time,
from any page.
An important feature of the NavTalk is the com-
bined GPS/Cellular Status Bar that appears at the bot-
tom of every main GPS and Cellular Page. The Status
Bar is important because it lets you know at a glance
the status of all the primary functions of your NavTalk.
The Status Bar appears in two sizes: large and regu-
lar. The large size Status Bar is displayed only at the
bottom of the Cellular Status Page and is divided into
two lines (see figure below).
The top line is dedicated to providing cellular infor-
mation and conveys three main pieces of information:
Zoom/Volume
Keys
Volume Adjust-
ment "Pop-Up"
Status Bar at the base
of the
Cellular Status Page.
