confirm the installation.
The .jar file is required for installation. If it is missing, the phone may ask 
you to download it. If there is no access point defined for Applications, you 
will be asked to select one. When you are downloading the JAR file, you may 
need to enter a user name and password to access the server. You obtain 
these from the supplier or manufacturer of the application.
During installation, the phone checks the integrity of the package to be 
installed. The phone shows information about the checks being carried 
out, and you are given options whether to continue with or cancel the 
installation. Once the phone has checked the integrity of the software 
package, the application is installed on your phone.

 INSTALL SOFTWARE
You can install applications that are specifically intended for the Nokia 3620 
and Nokia 3660 phones or suitable for the Symbian operating system. 
A software package is usually one large compressed file containing many 
component files.
Note: If you install a program that is not intended specifically 
for the Nokia 3620 and Nokia 3660 phones, it may function and 
look very different from the usual Nokia 3620 and Nokia 3660 
phone applications.
Warning: If you install a file that contains an update or repair to an 
existing application, you can only restore the original application if 
you have the original installation file or a full back-up copy of the 
removed software package. To restore the original application, first 
remove the application and then install the application again from 
the original installation file or the back-up copy.
Installation packages may be transferred to your phone from a computer, 
downloaded during browsing, or sent to you in a multimedia message, as an 
e-mail attachment, by Bluetooth connection, or by infrared. If you are using 
PC Suite to transfer the file, place it in the c:
okia\installs folder on 
your phone.
Example: If you have received the installation file as an e-mail attachment, 
go to your mailbox, open the e-mail, open the Attachments view, scroll to 
the installation file, and press   to start the installation. 
						

							[ 138 ] Start the installation:
To start the installation, open Manager, scroll to the installation package, 
and select Options→ Install. 
Alternatively, search the phone memory or the memory card for the 
installation file, select the file, and press   to start the installation. 
If you are installing software without a digital signature or a certificate, 
the phone warns you of the risks of installing software. Continue installation 
only if you are absolutely sure of the origin and contents of the 
software package. 
During installation, the phone checks the integrity of the package to be 
installed. The phone shows information about the checks being carried 
out and you are given options whether to continue or cancel the installation. 
Once the phone has checked the integrity of the software package, the 
application is installed on your phone.
To send your installation log to a help desk so that they can see what has 
been installed or removed, select Options→ Send log→ Via text message or 
Via e-mail (available only if the correct e-mail settings are in place).
 REMOVE SOFTWARE
1To remove a software package, scroll to it and select Options→ Remove.
2Press Yes to confirm the removal.
Warning: If you remove software, you can only re-install it if you 
have the original software package or a full back-up of the removed 
software package. If you remove a software package, you may 
no longer be able to open documents created with that software. 
If another software package depends on the software package that 
you removed, the other software package may stop working. Refer to 
the documentation of the installed software package for details.

 VIEW MEMORY CONSUMPTION
To open the memory view select Options→ Memory details.
Note: If you have a memory card installed on your phone, you will 
have a choice of two memory views, one for the phone or Phone 
memory and one for the Memory card. If not, you will only have the 
Phone memory view.
When you open either of the memory views, the phone calculates the 
amount of free memory for storing data and installing new software. In 
the memory views, you can view the memory consumption of the different 
data groups: Calendar, Contacts, Documents, Messages, Images, Sound 
files, Video clips, Applications, Mem. in use, and Free memory.
If the phone memory is getting low, remove some documents, or move 
them to the memory card. See also the “Troubleshooting” on p. 173.

17 Connectivity
Note: Your phone must be switched on to use the functions in the 
Connectivity folder. Do not switch the phone on when wireless 
phone use is prohibited or when it may cause interference 
or danger.
You can transfer data from your phone to another compatible device, for 
example, a phone or a computer, using a Bluetooth connection or infrared.
 BLUETOOTH CONNECTION
Go to Menu→ Connect.→ Bluetooth.
Bluetooth connectivity enables cost-free 
wireless connections between electronic 
devices within a maximum range of 30 feet. 
A Bluetooth connection can be used to send 
images, texts, business cards, and calendar 
notes. It can also be used to connect wirelessly 
to products with or using Bluetooth wireless 
technology, such as computers. 
Since Bluetooth devices communicate 
using radio waves, your phone and the 
other Bluetooth device do not need to 
be in direct line-of-sight. 
The two devices only need to be within a maximum of 30 feet (10 meters) 
of each other, although the connection can be subject to interference 
from obstructions such as walls or from other electronic devices. 
Using the Bluetooth application consumes the battery and the phones 
operating time will be reduced. Take this into account when performing 
other operations with your phone.
There may be restrictions on using Bluetooth devices. Check with your 
local authorities.

Bluetooth device compatibility
The Nokia 3620 and Nokia 3660 phones are designed to be compliant with 
and to adapt to Bluetooth Specification 1.1. Compatibility between the 
phone and other products with Bluetooth wireless technology depends also 
on the profiles and protocols used by both devices. The current profiles 
supported by the Nokia 3620 and Nokia 3660 are:
Dial-Up Networking profile (DUN) as a gateway
Fax profile (FAX) as a gateway
Object Push profile (OPP) as a client and server
File Transfer profile (FTP) as a server
Handsfree profile (HFP) as an audio gateway
Generic Object Exchange profile (GOEP)
Generic Access profile (GAP)
Serial Port profile (SPP) with the PC connectivity software
For information on compatibility with other Bluetooth devices, contact 
their manufacturers.
Activate the Bluetooth application for the first time
When you activate the Bluetooth application 
for the first time, you are asked to give a 
Bluetooth name to your phone.
After you have set the Bluetooth application 
to be active and changed My phones visibility 
to All, your phone and this name can be seen 
by other Bluetooth device users.
Write a name (max. 30 letters) or use the 
default name. If you send data using a 
Bluetooth connection before you have given 
an individual Bluetooth name to your phone, 
the default name will be used.
To send text using a Bluetooth connection (instead of text messages), go 
to Notes, write the text, and select Options→ Send→ Via Bluetooth.
