Navigation pointer, If a specific destination has been input, the arrow of
‡F
the pointer will keep pointing in the direction leading to the destination.
When installing batteries for the first time and failing to input a
destination, navigation pointer remains inactive, a state in which the
arrow disappears and the four axes stay right and stable while centered
data field shows the user's orientation.
‡G Compass icon-after calibration, the arrow keeps pointing to the
geomagnetic north. When installing batteries for the first time and
failing to calibrate, it remains fixed in NW, a character centering in the
ring of navigation pointer.

with the left one showing temperature from -10 to 24 degree in Celsius
or 14 to 76 degree in Fahrenheit, the right one showing from 25 to 60
degree in Celsius or 77 to 140 degree in Fahrenheit.
Distance data field, working as an odometer and straight line distance

calculator. When installing batteries for the time and failing to input a
destination before, it will not record the distance user travel and remain
showing zero. Only when a certain destination is input does the
odometer start recording the distance

Local time clock, acting as the type in common use, hour, minute and

second of which can be set or calibrated according to GMT. When
installing batteries for the first time, it runs from zero.
Note: When in use or because of low battery shutdown, removing batteries
from the unit for a shot time will not cause losses of geographic information,
navigational and timing data,however force the local time clock to stop running
and therefore cause a delay of time slot when reinstalling batteries to the unit.
Greenwich Mean Time, after a successful start (the first position has
‡K
been fixed), synchronize the time retrieved from GPS satellite
transmitted data which is in accordance with the universal time
coordinate. If GPS signal fails to reach the unit (or GPS signal icon
start blinking), it stop running and keep showing the time, until having
tracked the GPS signal again.
‡L Speed data field, functioning as speedometer, displaying the instant
speed of the unit after a successful start.If GPS signal fails to reach the
unit (or GPS signal icon
reflect the real speed of the unit until having tracked the GPS signal
again.
‡N
Satellite Icon, after a successful, the number of it indicates how many
satellites are being tracked. As soon as GPS signal is obstructed from
reaching the unit, all the icon will disappear from the display.
Battery icon, performances as remaining battery power indicator with
icon signifying full power,
Altitude data field, after a successful start (the first position has been

fixed), always display user's current altitude; before that it keep display
the altitude of the last position fix. When installing batteries for the first
time and before the first position fix, this field keeps showing zero.

Of 15 degrees of longitude centered upon a central meridian. This central meridian for a zone is
defined in terms of its position relative to a universal reference, the GMT (Greenwich Prime
Meridian). In other words, the central median of each zone has a longitude divisible by 15 degrees.
The number of hours that must be added or subtracted from local civil time in the zone to
Greenwich time depending on East longitude and West longitude.
Battery Status Icon
Just below the altitude data field locates the battery status icon. Capacity of batteries in use is
divided into four scales, with icon
user to recharge the batteries when batteries status icon is empty. The Polaris incorporates low-
battery shutdown technology in its hardware, at the moment when remaining power can not
sustain the whole system, the unit will automatically turn off and save all data.
Since Polaris can be power-sourced both from rechargeable type of batteries, such as NiMH/
NiCd and Non-rechargeable type as Alkaline, it's recommended to pay enough notice to the type
of battery. Remember to push the charging switch to lower side when installing non-rechargeable
battery.
To charge, user should make sure rechargeable batteries are in use and charging switch in the
upper side. When batteries is charged to full, Icon.
automatically reduce charging current to a very low value so that no damages will be caused when
user fail to remove the charging plug from the charging port.

Figure 14 illustrates the Polaris's thermometer which is divided into two graded bars with
different range of temperature joined at 24 Celsius degree. The left signifies the celsiur scale from
ten below zero to 24 degrees above zero while right signifies from 25 to 60 degree above zero.
