Important safety information  
Important safety information  
Read the following information before using the Nortel DECT Handset  
4025.  
CAUTION  
Like all cordless telephones, this handset  
uses radio signals, which do not  
guarantee a connection setup under all  
circumstances. Generally, you should not  
rely exclusively on cordless telephones  
when making indispensable calls (such as  
medical emergencies).  
The CE symbol on the product certifies its conformity with the technical  
guidelines concerning user safety and electromagnetic compatibility valid  
at the time of approval in accordance with European directive No.  
91\263\EEC.  
This product complies with IP50, according to IEC 529/EN60 529. Use  
only in countries where authorized.  
Sensitive electronic equipment  
Any radio-based equipment can potentially cause interference with other  
equipment and can receive interference from other equipment. This  
potential also applies for DECT equipment. However, due to the very low  
transmission power used by DECT equipment, the risk of interference is  
very small.

Important safety information  
Safety precautions  
Observe the following  
WARNING  
Do not open the handset or charger. Doing so could  
expose you to high voltages. Have all repairs carried out  
by authorized service personnel.  
CAUTION  
Do not allow the handset and charger to come into  
contact with water or chemicals.  
Do not allow the charger and the battery contacts to  
come into contact with conductive objects such as  
keys, paper clips, rings, or bracelets.  
This product contains magnetic material. Be aware  
that small metallic objects may stick (for example) to  
the loudspeaker. This may deteriorate the audio  
quality and can be harmful.  
WARNING  
Do not use the handset in a vehicle or hazardous  
location.  
CAUTION  
Use only the plug-in AC adapter and battery type  
supplied.  
Ensure the adapter voltage is the same as the  
electrical outlet voltage.  
Do not use AC adapters that are visibly damaged  
(cracked or broken housing), and keep the ventilation  
slits on the AC adapters free of obstruction.

Setting up the handset  
Setting up the handset  
Before you use the handset, it is important that you read the safety  
information and perform the following steps:  
1. Install the charger.  
2. Install the batteries.  
3. Charge the batteries.  
4. Subscribe the handset to the DECT system.  
Installing the charger  
Place the charger on a flat, even surface. To operate the charger, a mains  
connection is required. Ensure that the mains voltage matches the  
adapter mains voltage. Connect the charger to the mains connection.  
1. Connect the cable on the plug-in AC adapter to the terminal on the  
bottom of the charger.  
2. Plug the AC adapter into the mains socket outlet.  
CAUTION  
Do not install the charger, handset, and accessories  
near:  
water, moisture, or dampness  
sources of heat and direct sunlight  
devices that generate strong magnetic fields,  
electrical appliances, fluorescent lamps, computers,  
radios, televisions, or fax and telephone terminals  
12  
 
     
Setting up the handset  
CAUTION  
Do not install the charger, handset, and accessories in:  
areas where the handset can be covered, or in  
locations with poor ventilation  
areas where there is excessive dust and areas  
subject to vibration, shock, or extreme temperature  
fluctuations  
CAUTION  
Keep the charger, handset, and accessories out of  
reach of small children.  
Your handset is operational only after the batteries have been charged.  
You can then use the handset to make and receive calls.  
13  
 
Setting up the handset  
Installing the batteries  
The battery compartment is on the back of the handset. It takes the three  
type AAA batteries that are supplied. Please refer to “Important battery  
Figure 1 illustrates how to insert batteries in the DECT Handset 4025.  
Figure 1: Inserting the batteries

1. Insert a small item, such as the top of a ballpoint pen, into the hole at  
the bottom of the compartment cover. Push in and lift the cover at the  
same time, as shown in Figure 1.  
2. Insert the batteries in the battery compartment, taking care to observe  
the correct polarity. Make sure that the + - poles of the batteries  
correspond to the + - markings in the battery compartment.  
3. Replace the cover by placing it on the compartment at a slight angle  
and pressing it down until it clicks into place.

Setting up the handset  
Important battery information  
Heat or cold reduces the performance and service life of the batteries. It is  
possible that a handset with hot or cold batteries can be temporarily out of  
operation even if the batteries are fully charged.  
WARNING  
Do not dispose of the batteries in a fire. Recycle or  
dispose of batteries in accordance with local  
regulations.  
WARNING  
Do not replace the batteries in potentially explosive  
environments, such as rooms where flammable liquids  
or gases are present.  
CAUTION  
Do not charge the batteries unless you use the supplied  
charger and the proper batteries.  
Charging the batteries  
Place the handset in the charger.  
CAUTION  
Use only rechargeable AAA NiMh batteries of typical 800  
mAh, 1.2 V.  
CAUTION  
The batteries can become hot during the first charge  
cycle.  
15  
 
       
Setting up the handset  
CAUTION  
Avoid placing the handset in the charger when fully-  
charged batteries have been removed from the handset  
and inserted again. They can become overcharged.  
Charging guidelines  
Charge the batteries for at least six to seven hours before using the  
handset for the first time. This protective measure extends the service  
life of the batteries.  
The maximum power output is attained only after three to five  
charging and discharging cycles.  
Do not leave the handset connected to the charger longer than one  
month without using.  
The batteries can be charged and discharged hundreds of times, but  
eventually they will be worn out. If the operating time (that is, talk and  
standby time) is significantly shorter than usual, it is time to replace  
the batteries.  
To maintain optimum operating time, the batteries should be  
discharged from time to time by not placing the handset in the  
charger but leaving it switched on until it switches itself off. Use only  
this method to discharge the batteries.  
Extreme temperatures influence the charging capability of the  
batteries.  
Operating times  
Empty batteries require six to seven hours to fully charge.  
When a fully-charged handset is switched off, it discharges in  
approximately one week.  
When batteries are fully charged, the handset has approximately 20  
hours of talk time or approximately 200 hours of standby time.  
Charge display  
The handset display screen shows the battery charge status. When the  
battery capacity is almost exhausted, an alert tone sounds in the form of  
16  
 
           
Setting up the handset  
three short “beep” signals (only during a call). This indicates that  
approximately five minutes of talk time remains.  
See Figure 2 for battery charge status definitions.  
Figure 2: Battery charge status  
Fully charged - 75 to 100%  
Partially charged - 50 to 74%  
Partially charged - 25 to 49%  
Partially charged- 0 to 24%  
Batteries are empty.  
An alert tone sounds and the icon (frame) flashes.  
Note: When new batteries are inserted, a charge status icon does not  
display until a complete charge cycle has occurred. However, when  
partially charged batteries are inserted, then the charge status icon  
displays immediately.  
Subscribing the handset to a DECT system  
The handset must be subscribed to at least one DECT system before it  
can be used.  
Before you subscribe to a DECT system, acquire the following information  
from your system administrator:  
PABX-PIN — this code is used to access the DECT system  
DECT system name  
local phone number assigned to your DECT handset  
PARK-Code (a PARK-Code system ID that should be used only if  
more than one DECT system overlaps in your location)
