It takes a very long time or I am unable to send an SMS or MMS. What do I do?

If you have problem sending an SMS or MMS, please perform the following checks:

●You should have at least 1.5 to 2 MB of free memory space on your HP iPAQ so that the device operates efficiently. To check the free memory space, tap Start > Settings > System > Memory.

●Is the reception of the network signal good? You might be located within closed boundaries. If yes, move to an open space or closer to a window. For more information, see Check connection and signal strength on page 22.

●Try to select your network manually. For more information, see View available phone networks on page 31.

●Contact your service operator, to check if the network has been set properly and necessary provisioning of services is available.

I cannot use certain call functions. What should I do?

To use certain advanced call functions, such as Call Forwarding and Call Barring, you might need to subscribe to these services from your service operator.

Why do I hear noises in the background during a phone call?

You might hear noises in the background if you use your HP iPAQ near electronic equipment, such as microwave oven, speakers, or a television set. Avoid using your HP iPAQ near such items as it has an adverse effect on the voice quality.

How can I improve the standby time and talk time on my HP iPAQ?

Follow the guidelines given below to improve the standby and talk times on your HP iPAQ.

●The HP iPAQ might consume more power when the signal reception is poor. Try to move to an open location when you use your HP iPAQ.

●If you are not using the Push e-mail service, a service that continuously checks for e-mail messages with the Web server, disable it as it consumes excessive battery capacity and reduces the standby time.

●If you are using a new battery, it might take several charging and discharging cycles to reach its original capacity. Use the HP iPAQ after charging the battery completely. The solid green LED display indicates full battery charge.

●Do not overcharge or completely discharge the battery, as it might damage the battery and reduce the standby and talk time.

●If your battery is very old, replace it with a new one.

●Avoid using the HP iPAQ in very high or low temperature environments. The efficiency of a battery can be affected by extreme temperature conditions. To know more about the operating temperatures on your HP iPAQ, see Operating environment on page 118.
