TIP: It may be wise to do a very short sample program
to be sure everything is set correctly. For example,
choose a 10 minute recording session called “test 1”
and evaluate results.
TIP: Make sure to leave the PowerPad
®
on until the
recording is completed and check that there is AC
power or enough time left on the battery.
