I tried to do a modem HotSync operation, but it did not complete successfully. (continued)

Check the following on your handheld computer:

■Confirm that the telephone cable is securely attached to your modem.

■Make sure the dialing instruction dials the correct phone number.

■If you need to dial an outside line prefix, make sure you selected the Dial Prefix option on your handheld computer and entered the correct code.

■If the telephone line you are using has Call Waiting, make sure you selected the Disable call waiting option under Modem Sync Phone Setup on your handheld computer and entered the correct code.

■Make sure the telephone line you are using is not noisy, which can interrupt communications.

■If you are using an external modem, make sure your modem resets before you try again. (Turn off your modem, wait a minute, then turn it back on.)

■Check the batteries in your modem and replace them if necessary.
