SETUP
In the manual mode, the unit does not switch legs. Instead "ARRIVED" is
displayed at the bottom of the screen, and the unit continues to compute
navigation information referenced to the destination waypoint you just
passed. You must switch to the next leg manually by displaying the current
route with ROUTE and using the RIGHT ARROW to select the next leg and
then press NAV to continue navigating.
Access SETUP 14. Press the RIGHT ARROW to toggle between auto-
matic and manual leg switching modes.
SETUP 15 — Velocity Average. Velocity-related values (such as SOA and
SOG) are based on an instantaneous measurement of speed (velocity). In
practice, the instantaneous nature of the velocity measurement makes the
values based on it vulnerable to momentary fluctuations in velocity. The
measurements appear to vary from one moment to the next, sometimes
considerably.
Velocity Average allows you to replace the instantaneous measurements
with a weighted average, taken over a selected number of seconds. This has
the effect of "smoothing" and stabilizing the values displayed on the screen.
Velocity Averaging can be set to NONE, every 20 SECONDS, or every 120
SECONDS.
Access SETUP 15. The default setting is NONE. To choose a different
setting, press the RIGHT ARROW to scroll through the available values.
SETUP 16 — Battery Saver. The Battery Saver allows you to choose how
long the unit operates (continuously or 2-minute periods) when using battery
power.
When the Battery Saver is off, the unit operates until it is turned off with the
ON/OFF key or until 2 minutes after the second battery warning appears.
Battery Saver off is the default setting.
When the Battery Saver is on, the unit obtains position fixes for 2 minutes and
turns itself off. This drains relatively little power from the batteries. (The unit
will not turn itself off during Almanac Collect or Almanac Verify.)
Several of the unit's functions require that the unit operate for more than 2
minutes. At the same time, operating with the Battery Saver off is a heavy
drain on the batteries. We therefore recommend that you operate from
external power when averaging, collecting data, downloading or logging
data, and navigating on a route.
Battery Saver on is useful primarily as a means to conserve power when the
batteries are low and when performing single-fix positioning.
