radio signals from 3 or more GPS satellites. The

triangulating error allowed by the GPS satellites

is about 30 m (98 feet). Depending on the

environment of the location, the triangulating

error can be greater. In this case, your actual

location may not match the location on the map

based on the GPS information. Meanwhile,

the GPS satellites are controlled by the Unites

States Department of Defense, and the degree of

accuracy may be changed intentionally.

Error during the triangulating process

The camcorder acquires location information

every 10 seconds during triangulating. There

is a slight time difference between when the

location information is acquired and when the

location information is recorded on an image,

therefore, the actual recording location may not

match exactly the location on the map based on

the GPS information.

On the restriction of use of GPS on an airplane

During take off and landing of an airplane,

set the GPS switch to OFF and turn off the

camcorder, as you will be instructed to do by

the on-board announcement. In other cases, use

GPS in accordance with the regulations of the

place or situation.

On the map data

The camcorder contains map data for the

following countries/regions.

Europe, Japan, North America, Oceania, etc.

Built-in map is powered by companies as

follows; Map of Japan by Zenrin Co., Ltd., other

areas by NAVTEQ.

The map data included is as of the date of

production of this manual.

GPS maps will appear in 2-dimensional

graphics except for certain landmarks in Japan,

which will appear in 3D.

The map always displays the north at the top.

You cannot change the language on the map.

You cannot update the map data.

The scale of the map is 25 m to 6,000 km (or

100 feet to 6,000 miles).




About GPS

The GPS system consists of 24 or more GPS

satellites. A GPS receiver receives radio signals

from the satellites, and calculates the current

location of the receiver based on the orbital

information (almanac data) and travel time of the

signals, etc.

Determining a location is called “triangulating.” A

GPS receiver can determine the location’s latitude

and longitude by receiving signals from 3 or more

satellites.

As the positions of GPS satellites vary

constantly, it may take longer to determine

the location or the receiver may not be able to

determine the location at all, depending on the

location and time you use the camcorder.

“GPS” is a system for determining geographic

location by triangulating radio signals from

GPS satellites. Avoid using the camcorder

in places where radio signals are blocked or

reflected, such as a shadowy place surrounded

by buildings or trees, etc. Use the camcorder in

open sky environments.

You may not be able to record location

information at locations or in situations where

radio signals from the GPS satellites do not

reach the camcorder as follows.

In tunnels, indoors or under the shade of

buildings.

Between tall buildings or at narrow streets

surrounded by buildings.

In underground locations, locations

surrounded by dense trees, under an elevated

bridge, or in locations where magnetic fields

are generated, such as near high voltage

cables.

Near devices that generate radio signals of the

same frequency band as the camcorder: near

1.5 GHz band mobile telephones, etc.

On triangulating errors

If you move to another location right after

setting the GPS switch to ON, it may take

a longer time for the camcorder to start

trianguating, compared to when you stay in the

same place.

Error caused by the position of GPS satellites

The camcorder automatically triangulates your

current location when the camcorder receives
