13-2
consecutive prompts or error messages will make it easier for
the user to distinguish between them.
•
Consider using the “Data Security” option to prevent the
operator from accidentally exiting “Data Collection” by
pressing the
F1
key instead of the intended
F2
key (the
F2
key replays the current voice message).
•
Be sure to record error messages for all possible problems
that the user may encounter during a data collection session.
Once the operator becomes accustomed to listening to the
voice prompts, it may become easy to overlook a “display
only” error message.
•
Use a barpad table and Accumulate Mode to enter numeric
data. This allows the operator to scan everything and avoid using
the keypad. Data collection becomes a simple “listen and scan”
operation. This has the potential to greatly speed up the entire data
collection process.
TriCoder's Voice Message Mapping
The TriCoder is shipped with 75 seconds of total recording time. The time
allotted for each message is partitioned as follows:
30 – ½ second messages (message numbers 01-30)
30 - 1 second messages (message numbers 31-60)
15 - 2 second messages (message numbers 61-75)
Messages are sequentially numbered beginning with the ½ second
messages, followed by the 1 second messages, and finally the 2 second
messages. You can change the partitions to allow for more or less of a
particular length message. For example, if you decide you do not want any
½ second messages and you want 15 more 1 second messages, your
allocation would look like this:
00 – ½ second messages
45 - 1 second messages (message numbers 01-45)
15 - 2 second messages (message numbers 46-60)
Voice message partitions are set in the TriCoder either from the bar coded
Setup Menu or by the keypad setup. From the Setup Menu, scan the bar
code for “Voice Messages”, and then scan six digits. The first 2 digits
correspond to the ½ second messages, the second 2 digits for the 1 second
messages and the last 2 digits for the 2 second messages. Remember that
the total amount of time must add up to 75 seconds.
