Guidelines for Safe and Efficient Use 1
General
Your terminal is a radio transmitter and receiver. When 
the terminal is turned on, it receives and transmits radio 
frequency (RF) energy. Depending on the type of termi-
nal you have bought, it operates in different frequency 
ranges and employs commonly used modulation tech-
niques. The system that handles your call when you are 
using your terminal controls the power level at which 
your terminal transmits.
Exposure to Radio Frequency Energy
The International Commission on Non-Ionizing Radia-
tion Protection (ICNIRP), sponsored by the World 
Health Organization (WHO), published a statement in 
1996 which sets limits for exposure to RF fields from 
handheld mobile terminals. According to this statement, 
which is based on the available body of research, there is 
no evidence that mobile terminals meeting the recom-
mended limits can cause any adverse health effects. All 
Ericsson telephones conform to the ICNIRP recommen-
dations and international exposure standards, such as:
•CENELEC European Pre-standard ENV50166-2
•ANSI/IEEE C95.1-1992 (USA, Asia-Pacific)
If you want to limit RF exposure even further, you may 
choose to control the duration of your calls and operate 
your terminal in the most power efficient manner.
Antenna Care and Replacement
•Do not bend the antenna since it is sensitive and 
this will reduce its performance.
•Do not use the terminal with a damaged antenna. 
Take your terminal to a qualified service center for 
repair.
•Do not use an antenna designed for any other type 
of telephone than the one you have bought. Unau-
thorized antennas, modifications, or attachments 
could damage the terminal and may violate the 
appropriate regulations and will void the warranty.
•Ericsson cannot guarantee the terminal being water 
resistant.
Battery
•The terminal is water-resistant when the battery is 
removed.
Guidelines for Safe and Efficient Use

2Guidelines for Safe and Efficient Use
•Do not use the terminal with a damaged battery. 
Use only the designated Ericsson battery.
•Do not use a battery designed for any other type of 
telephone than the one you have bought. Unautho-
rized batteries could damage the terminal and may 
violate the appropriate regulations and will void the 
warranty and Ericsson can not guarantee the termi-
nal being water resistant.
Driving
Check the laws and regulations on the use of telephones 
in the areas where you drive. If you are going to use your 
terminal while driving:
•Get to know your wireless terminal and its features 
such as speed dial and redial.
•When available, use a handsfree 
device.
•Position your wireless terminal 
within easy reach.
•Suspend conversations during 
hazardous driving conditions or 
situations.
•Do not take notes or look up phone numbers while 
driving.
•Dial sensibly and assess the traffic; if possible, place 
calls when you are not moving or before pulling 
into traffic.
•Do not engage in stressful or emotional conversa-
tions that may be distracting.
•Use your terminal to call for help.
•Use you terminal to help others in emergencies.
•Call roadside assistance or a special wireless non-
emergency assistance number when necessary.
•Give full attention to driving.
RF energy may affect some electronic systems in motor 
vehicles. In addition, some vehicle manufacturers forbid 
the use of mobile phones in their vehicles. Check with 
your vehicle manufacturer’s representative to be sure that 
your terminal will not affect the electronic systems of 
your vehicle.
Electronic Devices
Most modern electronic equipment, for example equip-
ment in hospitals and cars, is shielded from RF energy. 
However, RF energy from telephones may affect some 
electronic equipment.
•Turn off your terminal in health care facilities when 
regulations posted in the areas instruct you to do so.
•Do not use your terminal near medical equipment 
without requesting permission.
Mobile phones may affect the operation of some 
implanted cardiac pacemakers, equipment for people 
with hearing impairments and other medically 
implanted equipment. Pacemaker patients should be 

Guidelines for Safe and Efficient Use 3
aware that the use of a terminal very close to a pace-
maker might cause the device to malfunction. Avoid 
placing the terminal over the pacemaker, i.e. in your 
breast pocket. When using the terminal, place it at the 
ear opposite your pacemaker. If a minimum distance of 
15 cm is kept between the terminal and the pacemaker, 
the risk of interference is limited. Contact your cardiolo-
gist for more information.
Aircraft
•Turn off your terminal before boarding any aircraft.
•Do not use it on the ground without crew permis-
sion.
To prevent interference with aircraft systems, you must 
not use your terminal while the plane is in the air.
Power Supply
•Connect AC (Power supply) only to designated 
power sources as marked on the product.
•Make sure the AC (Power Supply) is dry and clean 
before you plug it in.
•To reduce risk of damage to the electric cord, 
remove it from the outlet by holding onto the AC 
adapter rather than the cord.
•Make sure the cord is located so that it will not be 
stepped on, tripped over or otherwise subjected to 
damage or stress.
•To reduce the risk of electric shock, unplug the unit 
from any power source before attempting any clean-
ing, then use a soft, damp cloth.
Blasting Areas
Tur n  o ff  your terminal when in a blasting area or in 
areas posted “turn off two-way radio” to avoid interfer-
ing with blasting operations. Construction crews often 
use remote control RF devices to set off explosives.
Potentially Explosive Atmospheres
Your Ericsson terminal is specially designed for use in 
hazardous environments or areas with potentially explo-
sive atmospheres. However, you must pay special atten-
tion and be more careful when using the phone in such 
environments.
The terminal is designed for use in these environments 
only with the specially marked intrinsically safe Ericsson 
battery included in your phone package. Do not use the 
phone with any other type of battery other than the one 
marked “Intrinsically Safe.”
Areas with a potentially explosive atmosphere are often, 
but not always, clearly marked. They include fuelling 

4Guidelines for Safe and Efficient Use
areas, such as gas stations, below deck on boats, fuel or 
chemical transfer or storage facilities, and areas where 
the air contains chemicals or particles, such as grain, 
dust, or metal powders.
Do not transport or store flammable gas, liquid, or 
explosives in the compartment of your vehicle, that con-
tains your terminal and accessories.
Children
Do not allow children to play with your terminal since 
they could hurt themselves or others or accidentally 
damage the terminal.
Product Care
Although the terminal is resistant to rain and running 
water, do not unnecessarily subject it to water. If you 
need to wash your terminal, it is recommended that you 
do it gently in cold water under a water tap. Make sure 
that your battery is properly connected, the antenna is 
properly screwed on and that all accessories are removed 
before you wash your terminal. Do not use any deter-
gent or washing powder.
•Do not immerse the product in water.
•Do not expose your product to liquids other than 
water.
•Do not expose your product to extreme tempera-
tures.
•Do not use any other accessories than Ericsson 
originals. Failure to do so may result in loss of per-
formance, fire, electric shock or injury, and will 
void the warranty.
•Do not attempt to disassemble the product. Doing 
so will void the warranty. This product does not 
contain consumer serviceable components. Service 
should be performed by Authorized Service Centers 
only.
•The terminal will not withstand dust, moisture or 
rain if the battery and/or the antenna are not prop-
erly connected.
•Removal of the battery and antenna should be done 
under dry conditions. Make sure that no moisture 
gets into the terminal.
Efficient Operation
To use your terminal for optimum performance with 
minimum power consumption:
•In the Phone Mode, hold the terminal as you 
would a telephone. While speaking directly into the 
mouthpiece, angle the antenna in a direction up 
and over your shoulder.
•In Radio Mode and Speakerphone Mode, hold the 
terminal in front of your face about 30 - 50 cm 
away and speak in the direction of the terminal.
Guidelines for Safe and Efficient Use 5
•Do not hold the terminal close to your ear while it 
is in Speakerphone or Radio Mode.
•Do not hold the antenna when the terminal is in 
use. Holding the antenna affects call quality, may 
cause the terminal to operate at a higher power level 
than needed and shorten talk and standby times.
6Guidelines for Safe and Efficient Use

Getting Started 7
Complete the following steps after you have removed 
your terminal and its components from the box:
1  Attach your belt clip or swivel to your battery 
(optional).

8Getting Started
Removing Your Battery
Removing the battery is the reverse of attaching it to the 
terminal.
1  Make sure that the terminal is turned off before 
removing the battery.
2  Press the two latches on the top of the battery.
3  Lift the battery up and away from the terminal.
Charging Your Battery
Your terminal is packaged with a rapid charger. You 
should fully charge the battery before you attempt to use 
your terminal. While you are charging your terminal 
with your rapid or travel charger, you will still be able to 
make and receive calls. You can purchase an overnight 
charger or a travel charger from your nearest Ericsson 
accessory retailer.
Never attach the charger to a terminal that does not have 
a battery installed.
1  Make sure that the battery is attached to the termi-
nal.
2  Connect the charger to the AC power.
3  Connect the other end of the cable to the terminal 
according to the picture. The flash symbol on the 
plug must face upward (you may have to press 
firmly).

Getting Started 9
The terminal automatically starts charging the battery 
when you attach the charger. The following indicate 
charging:
•The battery meter in the display will continuously 
fill and empty.
•The indicator on top of the terminal will show a 
steady red light (green, if the terminal is turned on).
When the battery is fully charged, the battery meter in 
the display shows full and the indicator on top of the 
terminal shows a steady green light.
Note! It is possible to use the terminal while the battery is 
being charged with the rapid charger or travel charger. 
This is not true with the overnight charger. Using the 
terminal to make or receive calls while the terminal is 
being charged will increase the charging time.
To disconnect the charger, first lift the plug connected to 
the terminal upwards and then pull it out.
Your Charger
Rapid Charger
The rapid charger supplies power to charge your battery 
while the battery is attached to your terminal. You can 
make and receive calls while using the rapid charger, if 
you wish. To charge your battery with the rapid charger:
1  Plug the charger into a standard wall electrical out-
let.
2  Hold the terminal with the display and keypad up.
3  Hold the small plug on the charger cord so the light-
ning bolt symbol is up.
4  Align the small plug on the charger cord with the 
connector on the bottom of your terminal. The con-
nector on the terminal is above the lightning bolt 
symbol.
5  Press the plug into the connector until the plug 
"snaps" into place.
Note! To disconnect the charger, first twist the plug connected 
to the terminal upwards and then pull it out.

10 Getting Started
Desk/Wall Stand
The desk/wall stand for your Ericsson rugged terminal 
serves both as a charger and a holder for the terminal. 
When the battery runs low, just place the terminal in the 
desk/wall stand to charge it (the charger must be con-
nected to the desk/wall stand).
The desk/wall stand, which consists of two separate 
pieces, can be placed on a table or attached to the wall. 
Separate and rotate the two pieces to change between 
desk and wall stand modes.
To use your desk/wall stand, do the following:
1  Separate the two pieces of the desk/wall stand (see 
picture below).
2  Place the desk/wall stand on a table or attach it to 
the wall.
3  Using the appropriate cord supplied with the 
charger, attach the terminal to the charger.
4  Plug the other end of the charger cord into a stan-
dard electrical wall outlet.
Note! The flash symbol must face upwards.
5  Place the terminal in the desk/wall stand for charg-
ing.

Getting Started 11
Travel Charger
The travel charger supplies power to charge your battery 
while the battery is attached to your terminal. You can 
make and receive calls while using the travel charger, if 
you wish. To charge your battery with the travel charger:
1  Using the appropriate cord supplied with the 
charger, attach the terminal to the charger.
2  Using the other cord supplied, plug the charger into 
a standard electrical wall outlet.
When to Charge Your Battery
The NiMH battery that comes with your terminal can 
be charged whenever you wish without losing perfor-
mance. This is not the case with the cheaper nickel cad-
mium type batteries, often sold as accessories from other 
suppliers. For optimal talk and standby time in the long 
run, we recommend that you only use Ericsson original 
batteries with your Ericsson terminal.
To remind you that the battery will soon need to be 
charged or replaced with a charged one, the following 
will occur:
•An alarm signal (a long beep) sounds and the mes-
sage Low Battery! appears for 10 seconds in the 
display.
•The indicator light on top of the terminal starts 
blinking red.
Note! If the terminal is left turned on, the low battery alarm 
will be repeated several times and, finally, the terminal 
will turn itself off when the battery is no longer able to 
power it satisfactorily. It might be possible to turn the 
terminal on again, but you will not be able to make or 
receive any calls. You should charge the battery or 
replace it with a charged one.

20 Basic Operations
Emergency Calls
Your terminal was programmed with an emergency 
number (911) when it was manufactured. The pro-
grammed emergency number can be dialed and called at 
any time, if there is a 911 system available, regardless of 
any call restrictions (except Keypad Lock) you have set 
through the   Menu. A representative from your 
service provider or the retail outlet where you purchased 
your terminal should be able to change the emergency 
number in your terminal, if a 911 system is not available 
in your service area.
If police, fire, or medical help is needed, dial 911 or your 
emergency number and press YES. Tell the dispatcher 
that you are calling from a wireless terminal.  Wireless 
911 calls do not automatically provide emergency per-
sonnel with your name, location, or terminal number.  
The dispatcher will want to know the following:
1  Your name and wireless phone number.
2  The nature of the emergency.
3  If police, fire, or medical assistance is needed.
4  The exact location of the emergency including cross 
streets, mileposts, or landmarks.
5  How many people are involved, their condition, and 
if help is being administered.
Alert Calls
Use the Alert button on your terminal to automatically 
call a programmed Alert Number. to place a call, press 
and hold the Alert button. To display the default Alert 
Number, press and release the Alert button. Press   or 
 to select any of the 5 Alert Numbers that have been 
programmed into your phone. To change any of the 
stored Alert Numbers, see the section Recalling Num-
bers.
Note! The factory default Alert phone number is 911.
International Calls
If allowed by your system, you can place international 
calls with your terminal just as you would from any 
phone.  If you have difficulty completing international 
calls, check with your system operator for information.
Caller Number Identification
If your system provides Caller ID service, your terminal 
shows the phone number of an incoming call in the dis-
play.  Also, if the number is one that you have stored in 
memory with a name, the name is shown with the 
phone number when your terminal rings.  If  the Caller 
ID information is not available, the message NO ID  or a 

Basic Operations 21
blank line is shown in the display.  The word Private 
may be shown if the caller ID is restricted by the system.
Low Battery Power Alert
The low battery alert sounds when your battery is reach-
ing its lowest operational power level.  The words Low 
Battery flash in the display, and the indicator light on 
top of your terminal flashes red.  When this happens, 
leave your terminal turned On.  The terminal discharges 
the battery and then shuts itself Off.  You should charge 
the battery within 24 hours so that the battery can 
charge to full capacity.
Security Code
Your terminal has a security code that you must enter to 
gain access to certain functions, such as call restrictions 
and calling card numbers. The factory-programmed 
code is 0000. You should change this code to provide 
maximum security for your terminal.
Group Calling with TDMA Pro
If your service provider has the Ericsson TDMA Pro 
Server, the R250d terminal supports group calling. Eric-
sson TDMA Pro supports calling a group of phones by 
dialing a single group number defined in the TDMA 
Pro database. When the terminal calls a group or receives 
a group number, the display will indicate the group 
name associated with the number on the second line of 
the display.
When the call is active, the terminal will display the 
group or alert call type on the third line of the display as 
shown below.
The following group call types may be available:
•Talk - A group call where all member numbers are 
dialed simultaneously and each member is included 
when the terminal is answered. An active Talk 
group call includes all members of the group who 
answered the call. This is a two-way voice conversa-
tion. Your terminal will automatically answer Talk 
group calls when Radio Mode is selected.
•Broadcast - A group call where live or pre-recorded 
broadcast voice is sent to all member numbers of 
the group when the terminal is answered. This is a 
one-way voice conversation. Your terminal will 

22 Basic Operations
automatically answer Broadcast group calls when 
Radio Mode is selected.
•Sequential - A group call where each member num-
ber is dialed in a sequential order until one member 
answers. When one member answers, the call is 
active. This is a two-way voice conversation.
•First Answer - A group call where all member num-
bers are dialed simultaneously until one member 
answers. When one member answers, the call is 
active and ringing stops on the other terminals. 
This is a two-way voice conversation.
Your Ericsson rugged terminal provides a flashing dis-
play when answering a call associated with an Alert 
number stored in the TDMA Pro database or the termi-
nal Alert number memory. The terminal can store 25 
group numbers and five Alert numbers. You must enter 
your security code before you can store or delete Group 
numbers or Alert numbers.

Storing and Recalling Numbers 29
You can store phone numbers and associated names in 
your terminal’s memory to use for Recall dialing, Speed 
Dial, and Super Dial.  Each number you store can be up 
to 32 digits in length, and any names you store can be 
up to 24 characters in length. Group and Alert Numbers 
are accessed through   and   
submenus.

Message Services 33
Your terminal can receive two types of message service 
(text messages and voice mail) if these services are avail-
able from your service provider.  If you subscribe to 
either or both services, callers can leave you text mes-
sages or voice mail.  Your service provider then transmits 
the text messages and voice mail notifications to your 
terminal.
Text Message Service
Your terminal supports three message categories:  Nor-
mal, Urgent, and Emergency.  The actual tagging of the 
text message is dependent on the system used by your 
service provider.  Your service provider transmits mes-
sages to your terminal.  If your terminal is On, it receives 
the messages as described below.  If your terminal is not 
turned On, your service provider retains the messages 
and transmits them again later.
Note! Your Ericsson rugged terminal holds up to 10 messages 
or a maximum of 2KB of message text.
When reviewing a text message, the status of the text 
message is shown using the following letters:
•R - Read, text message has been read but not saved.
•S - Saved, text message has been read and saved.
•U - Unread, text message has not been read.
Normal Messages
If your terminal is turned On when it receives a normal 
text message, your terminal sounds a brief tone and a 
message similar to the one in this illustration is shown in 
the display. After 10 seconds, the message will be saved 
and the text message icon ( ) will appear in the dis-
play. You have a choice of reading the message immedi-
ately by pressing YES, or reading it later by pressing NO.  
Pressing NO clears the message received alert from the 
display and places a number and icon in the display to 
remind you of your messages.
Urgent Messages
If your terminal is turned On when it receives an urgent 
text message, your terminal sounds a brief tone and a 
message similar to the one in this illustration is shown in 
the display.  As with normal messages, you have a choice 
of reading the message immediately or reading it later.  
Urgent messages are always shown before normal mes-
sages, regardless of the order in which they were 
received.
Message Services

34 Message Services
Emergency Messages
If your terminal is turned On when it receives an emer-
gency message, your terminal sounds two brief tones,

Call-Back Messages
Some text messages you receive may be call-back mes-
sages.  A call-back message contains one or more phone 
numbers included by the person sending the message. If 
you press YES while reading a call-back message, a screen 
similar to the one shown here appears. To dial the dis-
played number, press YES (to place a calling card call to 
the displayed number, press and hold YES). If you do not 
wish to call the displayed number, press NO to resume

where calls are dropped and contact your service 
provider.
The signal strength 
varies.
This is a common occurrence.  Transmitter sites 
are set in geographic areas, and coverage is not 
100% all of the time.  Signal strength varies as you 
travel between cells.
