ALTITUDE / TIME FUNCTIONS
ALTITUDE.
The Vertech shows current
altitude above or below sea level from
-4,000 feet to +30,000 feet in 5 foot incre-
ments in the upper display.
ALTITUDE OFFSET.
Weather changes
produce changes in barometric pressure
that cause an offset in the displayed altitude
from the actual altitude. This offset is con-
sistent at any altitude, so if you start a hike with the altitude reading 50
feet high, it will remain 50 feet high at any elevation on your hike. You
can remove the offset by adjusting the altitude. When you adjust, you
set the displayed altitude to the actual altitude.
WHEN TO ADJUST ALTITUDE.
Altitude offset has no effect on
other Vertech functions, so there is no need to adjust until you want
to use the altitude function. Adjust at a known altitude such as at the
sea side, a marked summit or pass, or a location with an altitude
reference on a map such as a lake. Home or office make convenient
adjustment points after learning their elevations from a topographic
map. Adjust once a day when hiking or climbing or more often to
increase precision.
HOW TO ADJUST ALTITUDE.
Press the Adjust Button when in
the Altitude/Time function (A1). The altitude digits blink. Change them
with the Option Button. Altitude increases when the arrow on the left
of the display points up, and decreases when it points down. When you
reach the correct altitude, press the Adjust Button to exit.
SETTING THE DATE.
The date is shown in month / day / year
format. To set the date press the Adjust Button in the Date/Alarm
function (A2), then press the Function Button twice. When the month
digits blink advance them with the Option Button. At the correct month
press the Function Button, then advance the day with the Option
Button. At the correct day press the Function Button and advance the
year with the Option Button. At the correct year press the Adjust
Button to exit.
RESETTING MAXIMUM ALTITUDE.
The Maximum Altitude
function shows the maximum altitude reached since last reset to within
5 feet. To reset press the Adjust Button in the Maximum Altitude/
Countdown Timer function (A3). The altitude digits blink. Press the Start/
Stop button to reset to the current altitude. Press the Adjust Button to
exit or press the Function Button to set the countdown timer.
Adjust when you are at a known altitude such as sea level or at a landmark
with its altitude marked on a map. Adjust the altimeter by pressing the
Adjust Button when you are in the Altitude/Time function. When the altitude
digits flash, adjust in the direction of the arrow with the Option Button.
SWITCHING FROM FEET TO METERS.
To change the units
displayed from feet to meters press the Adjust Button in the Altitude/
Time function (A1). When the altitude digits are blinking, press the Start/
Stop Button to switch from feet to meters. When you switch the units,
accumulated vertical is converted to meters, vertical rates display in
meters, the Thermometer is switched to Celsius, and the Sea Level
Barometer displays in millibars.
SETTING THE CLOCK.
Press the Adjust Button in the Altitude/Time
function (A1). The altitude digits blink. Press the Function Button and the
clock hour digits blink. Advance them with the Option Button. In the 12-
hour clock “P” indicates that the hour is PM. At the correct hour press the
Function Button. The minutes blink. Advance them with the Option Button.
At the correct minute press the Function Button. The seconds blink. Press
the Option Button to zero them. The seconds advance continually because
the clock runs in the adjust display. To switch between 12 and 24 hour clock

clock, press the Adjust Button to exit.
To set the clock, press the Adjust Button in the Altitude/Time function. Press the
