Media Object Timing 
Timing of individual media objects must be within the overall slide time except for audio. This 
provides plenty of flexibility and greatly reduces the complexity of building a presentation. 
 
The user may add text, an image and a sound clip to each slide. The timing of each within the 
slide can be adjusted. The default timings are as follows: 
 
 
Object type  Start Point  
(Seconds from start of slide) Default Duration 
(Seconds)...

The user may shorten slide duration to less than 
the duration of the audio track. If there is audio 
on the next slide, the audio will be stopped and 
the track for the next slide will be played. 
 
If there is no audio on the next slide, the audio 
track will continue playing until it finishes or a 
later slide is displayed which has its own audio 
track. 
 
If Page time is un-checked, then the display 
time for the text can be set to shorter than...

The P800 has much greater capability than that stated above. The user may therefore choose 
between two conformance modes: Standard and None. The setting may be found in Control 
Panel, Messaging accounts, MMS, Advanced. Standard mode is useful when sending messages 
to smaller MMS-capable phones. 
 
In Standard mode, the user may select any media items, but will be warned if the selection falls 
outside of the standard. For example: 
• 
Selection of a...

Composing a multimedia message 
Multimedia messages may be created in FC or, as shown below, in FO mode. 
 
 Composing an multimedia message is like building a small slide 
presentation. A typical slide will consist of a picture, some text 
and a sound. Text and sound can be added to complete a slide. 
 
The user can set the duration of the slide. If a sound is added, 
the slide duration is set to the duration of the sound clip. 
 
Slides can be chained...

Receiving a multimedia message 
Incoming MMS messages typically arrive just like SMS messages – automatic delivery with 
notification to the user. Messages are located in the MMS Inbox.

Receiving a multimedia message on other terminals 
Interoperability is dependent upon the capability of the receiving terminal and the MMS server in 
the mobile network. Here are some examples....

MMS technical features 
The MMS standard, just like SMS, offers store and forward transmission (instant delivery) of 
messages, rather than a mailbox-type model. MMS is a person-to-person communications 
solution, meaning that the user gets the message directly into the mobile. He or she doesn’t have 
to call the server to get the message downloaded to the mobile. GPRS enables a continuous 
connection and rapid transfer of data.

Message conversion 
The MMS-C is able to perform limited message conversion - for example, from MMS to SMS – so 
that processing and air time is not wasted in sending messages to mobile terminals that do not 
have adequate capability to receive them. It also handles service aspects such as store and 
forward, guaranteed delivery, subscriber preferences, operator constraints, and billing 
information. The MMS-C also vouches for high quality messaging,...

corresponding ‘Synchronised e-mail account’ inbox on the P800.  Messages and replies written 
using this account on the P800 are transferred and sent via the PC. 
 
Web and WAP based E-Mail can, of course, be accessed using the P800’s browser. 
 
Technical Explanation of E-Mail 
Configuring and using the E-Mail client in Messages is very straightforward in most cases, 
especially where the e-mail service is provided by the mobile operator. Reading e-mail...

In case (1) User A will connect using a circuit –switched call in much the same way as User B. A 
circuit-switch call will be established from the Interworking Centre (IWC) at the mobile operator to 
the modem bank at ISP-A. The P800 Messages application will perform a ‘Get&Send’ operation. 
Messages will access the POP server at ISP A and collect waiting messages. 
 
If User A now replies to the message and selected ‘Send Now’ on the P800 whilst...

In the above example, there are 6 waiting e-mails on the POP server when the P800 does the 
first Get&Send for the mail account. After the Get&Send all 6 e-mails are copied to the P800 
inbox (header only or body, depending on advanced settings). The user then deletes messages 2 
and 5. After the second Get&Send, messages 2 and 5 have also gone from the POP server. 
 
If the P800 discovers during a Get&Send that a message has been...
