1. Introduction
1.1. General warning notes
•The PMR-GPS should be used as an aid in navigation. The unit is not intended to replace
basic navigational procedures and common sense.
•When using this device in a vehicle, use it only when the vehicle is stopped and it is safe to do
so. Operating the unit while driving is dangerous and could result in an accident or collision. It
is more important to keep your eyes on the road and hands on the wheel.
•Do not operate the transceiver in Countries where PMR 446 is not allowed. Apply for individual
licence where necessary.
•Remove the batteries from the unit if it is not expected to be used for long periods.
This will eliminate the possibility of chemicals leaking from the batteries and corroding the
unit.
•Avoid exposing the unit to water or extremes of temperature.
•Do not use this device in or near a mining facility, which uses remotely triggered explosives
or in areas labeled “Blasting Area”. Premature or accidental detonation may result.
•Do not attempt to modify or in any way increase the output of this transceiver. Its output is
designed to meet the legal limits set by the EU Standards.
•Do not use this device or change its batteries in potentially explosive atmospheres as sparks
in such areas could result in an explosion.
•Turn your transceiver off wherever posted notices restrict the use of radios or cellular tele
phones. Facilities such as hospitals may use equipment that is sensitive to RF energy.
•Turn your transceiver off on board aircraft when requested to do so.
•Do not place your radio in front of a vehicle’s air-bag. If the air-bag deploys, it could propel
the unit like a projectile causing severe injuries.
1.2. Important to know
•Never attempt to charge alkaline or other “normal” dry cell batteries. When recharging, use only
Albrecht’s approved and recommended 1300 mAh rechargeable NiMH batteries (order Nr. 29723)
and chargers. Use of the charger with other batteries can cause damage to your PMR-GPS unit.
Other types of batteries may burst and cause personal injury. Nickel-Cadmium batteries are not
receommended because of their lower capacity and the higher risk of “Memory Effect” compared
to NiMH batteries..
•Avoid installing the PMR-GPS unit in an area where it may be subjected for prolonged periods of
time to direct sunlight or temperatures below -4° F (-20°C) or above 140° F (60°C).
•Keep the antenna at least 2.5 cm away from your head and body when transmitting and do not
use your PMR-GPS transceiver with a damaged antenna.
•Use the rubber covers as protection of sockets when not in use.
1.3. Where is the radio part allowed to be used?
Use of this unit is allowed within the EU countries + Iceland, Hungary and Switzerland, except Italy,
and Norway. In Belgium, residents must apply for an individual licence, while use of PMR 446 is free
for travellers up to 3 months. In Norway and Italy the PMR 446 frequencies are still in use by other
services. In France, transmitting on channels 1 and 2 is not yet allowed for the same reason. If You
intend to use the radio in countries not listed on the gift box and in our “Declaration of Conformity”,
You should ask the telecommunications authority for a licence in advance. You may also obtain latest
informations from the Albrecht homepage http://www.albrecht-online.de, where You can also
download the latest conformity declaration version and country lists.
1.4. Reducing „Memory Effect“ of rechargeable batteries
The recommended 1300 mAh NiMH (Nickel-Metal-Hydrid) batteries (1 set = Order Nr. 29723) are
almost free of the so called „Memory Effect“, which is more common to normal NiCD battery types.

Cover of battery
compartment
With the memory effect, the operating time becomes shorter and shorter, if You should use the battery
only for a short time and if You should always recharge it immediately.
•If possible, recharge batteries only after they are completely discharged.
•Do not shorten the charging periods. Stop charging only after charging process is completed.
•Discharge and charge Your batteries minimum 2 x per months
•The best Idea is to use 2 battery sets. One set can be provided completely charged while the
other set is in use!
•3-4 complete discharge-charge cycles can repair memory effects!
The lifetime of a battery set is about 300 to 400 cycles. It is normal, that the operating time will be
reduced at the end of the battery lifetime. Please replace battery sets only complete and do not mix
old and new battery cells.
1.5. DC power supply
You may insert non rechargeable alkaline batteries (4 pcs AA type) or rechargeable NiMH batteries (4
pcs AA size 1300 mAh recommended) While alkaline batteries have a longer operating time, they
cannot be recharged. If You will use Your GP 1 often, we recommend to use NiMH rechargeable
batteries. There are three ways of charging the batteries: with a rapid stand charger within approx. 3
hours or with a 12 V cigarette lighter adaptor cable, which allows recharging from the 12 V car power
supply or a 230V wall charger (Nr. 7360) within approx. 14 hours (normal charging).
CAUTION: Before You use the rapid stand charger, make sure that only the recommended 4 pcs
1300 mAh NiMH batteries are inserted in the radio’s battery compartment! It is very dangerous to use
not rechargeable or other type of batteries together with the rapid stand charger. Not approved
batteries may leak, explode or even burn and can cause severe injuries!

Note: To avoid initializing of the CPU and system clock each time when You use the unit, parts of the
microcontroller and clock circuits are powered from the battery, even if the radio is switched off.
The current consumption is with 0.6 mA very small, it corresponds to the self-discharging currents of
rechargeable batteries, but may discharge an alkaline battery within approximately ½ year when not in
use. We recommend to take out batteries when You do not intend to use Your GP1 for a longer time
period.

2.4. The Global Positioning System (GPS) network
GPS is a world-wide radio navigation system formed by a group of 24 satellites (21 operating and 3
spares) and their associated ground stations. GPS uses these satellites, appropriately called
NAVSTAR (Navigation Satellite Timing and Ranging), to calculate ground positions. The basis of GPS
operation is the use of triangulation from the satellites. To triangulate, a GPS receiver measures
distance using the travel time of radio signals. However, to measure travel time, GPS needs very
accurate timing, plus it needs to know exactly where the satellites are in space. To solve this problem,
each of the 24 satellites is inserted into a high enough orbit (12,000 miles) to preclude interference
from other objects, both man-made and natural, and to insure overlapping coverage on the ground so
that a GPS receiver can always receive from at least four of them at any given time. In addition,
compensation is inserted for any delay the signal experiences as it travels through the atmosphere to
the receiver.
The GPS network was originally conceived by the U.S. Department of Defense (DOD) to aid
navigation.
How the system works
With the satellites operating at 12,000 miles above the earth’s surface, they are arranged in a strategic
positions and orbit the earth at a speed of 17,000 miles-per-hour, thereby completing an earth orbit
every 12 hours. Each is powered by solar energy; if that fails, they are equipped with on-board backup
batteries to maintain operational GPS integrity, and with small rocket boosters to keep them flying
along the correct path.
Satellite Frequency and control signals
Each satellite transmits a low-power radio signal in the UHF frequency range; the frequencies used
are designated as L1, L2, etc. GPS receivers, such as the PMR-GPS unit, listen on the L1 frequency
of 1575.42 MHz. This signal, since it is line-of-sight, will reach the ground receiver unless it is
obstructed by solid objects, such as buildings and mountains.
The L1 signal is accompanied by a pair of pseudo-random signals (referred to as a pseudo-random
code) which is unique to each satellite. These codes are identified by the GPS receiver and allow for
the calculation of the travel time from the satellite to the ground. If this travel time is multiplied by the
speed of light, the result is the satellite range (distance from satellite to receiver). The navigation
information provided by each satellite consists of orbital and clock data, plus delay information based
on an ionospheric model. Signal timing is provided by highly accurate atomic clocks.
Ground control
There are five GPS ground control stations ----- Hawaii, Ascension Island, Diego Garcia, Kwajalein
and Colorado Springs ---- that control the satellites by checking their operational disposition and exact
position in space. Four of these stations are unmanned, and the fifth -- Colorado Springs –is the
Master station. The four unmanned stations constantly receive data and send it to the Master station.
The Master station then provides corrections for satellite Ephemeris constants and clock offsets and,
in conjunction with two other antenna sites, uplinks this information to the satellites.
2.5. The GPS receiver
The GPS receiver, (in this case, the PMR-GPS unit), uses NAVSTAR satellite signals as a way of
determining exact position on earth. Mathematically, you need four satellite ranges to accomplish
these coordinates. Although three ranges are enough, an additional range is required for technical
purposes.
So, our position is based on how long it takes for a signal sent from the satellite to arrive at our
receiver. Since timing is everything, the satellite signal is almost perfect since it has an atomic clock on
board. But, what about our GPS receiver timing? Our receiver certainly contains no atomic clock; if it
did, its cost would be prohibitive -- nobody could afford it. To get around this problem, our receiver
must take an additional satellite measurement. Hence, it really needs four satellite signals to insure
our correct position. Since this fourth measurement, done as a cross check, will not intersect with the
first three, our receiver’s computer says, in effect, there is a discrepancy in my measurements, and I
must not be synchronized with universal time. Since any offset from universal time will affect all of our
measurements, the receiver looks for a single correction factor that it can subtract from all its timing
measurements that would cause them all to intersect at a single point.
That correction brings the receiver’s clock back into sync with universal time and, in this way, atomic
timing accuracy is in the palm of your hand.

Once our receiver has that correction, it applies to all the rest of its measurements and now we’ve got
recise positioning.
2.6. Combining GPS and Radio Features: Your GP 1
The Albrecht GP 1 provides you with the features of a precise hand-held GPS unit designed for
general purpose locating and navigation. Not only can it determine your actual position, it can also
guide you to a destination by establishing and storing waypoints to mark the trail or route, and allow
you to return to your original starting point.
But what makes this unit unique, is the incorporation of PMR capability, whereby your position can be
transmitted to another PMR-GPS unit, thereby allowing another party to know your exact position,
your intended route, and how long it will take you to arrive at that position.
By including three modes of operation, your PMR-GPS can act as a mobile radio transceiver only, as
a GPS unit only or as a combination of the two technologies for navigation and communication
purposes. The PMR-GPS incorporates the following features and capabilities:
•WAYPOINTS: The unit provides 150 waypoints with user-selected names and graphic
•symbols.
•ROUTE: Lets you navigate up to 10 routes with 20 waypoints in each route.
•TRACKS: Provides an automatic track log using 5 saved tracks; these tracks allow
•the user to locate the beginning and end point of each track.
•MARK: Allows the user to save and transmit his/her location to other GP 1 units
•tuned to the same channel (up to a distance of approximately 5 km).
•GP LOCATOR: Allows the user to receive and store position coordinates of other GP1 users.

4. First steps with Your GP 1
4.1. Initializing the GPS system mode
Before using the GPS mode of your GP 1 for the first time, the GPS receiver needs to determine its
new location automatically. GP 1 must initialize each time when You have travelled to a distant
location with Your switched-off GPS handheld. At the first time, after unpacking the GP 1, this
procedure may take some minutes. Later initializing procedures will be shorter. This is normal and
cannot be avoided.
4.2. Watching satellite acquisition on the GPS STANDBY page
Your GMR-GPS unit operates on positional data acquired from NAVSTAR
satellites.
To introduce Your unit to this information:
•Find a large, relatively open area that provides a clear view of the sky,
with a minimum of obstructions, such as buildings, radio towers, etc.
•Press and hold the Power/Mark (M) button on the left side of the unit for
at least 2 seconds.
A beep will sound and the standby screen will appear on the LCD. This screen
will automatically enter the RADIO + GPS mode (default mode).The GP 1needs
to receive at least three strong satellite signals to find your location.
The standby page graphically shows the unit acquiring satellites as the satellite
icons around the globe circumference become animated and darken.
SEARCHING appears under the ID bar at the top of the display. When you see
NAVIGATION appear, your GMR-GPS has found your location and you are
ready to use all of its GPS/radio capabilities.
If the unit is NAVIGATION, each of the satellites providing current GPS user
location should be highlighted, and should equal or exceed 3 as shown around
the circumference of the globe icon (4 or more is preferable). If the unit is
SEARCHING,wait approximately 5 minutes for the satellite(s) to find your
position. The NAVIGATION indication should appear.
Thereafter, during subsequent GPS operation, acquisition time should only take
from 5 to 45 seconds.
Note: Please be aware that the position data shown on the display are only correct, as long as
NAVIGATION appears on the display. After switching on the units, the display will initially show the
last measured location data, but always the “SEARCHING” indicates that the unit is still acquiring new
position data. Never trust position data as long as SEARCHING still appears.
