It is also possible to use a combination of keypad entries and barcode
entries. It might be desirable for the operator to use keypad entries for
clocking in/out and selecting tasks and only using the barcode labels for the
rows for instance.
Conversely, some customers might not appreciate the benefits of labelling
every row within a glasshouse yet want greater security over clocking in and
task selection. With this in mind a barcode only mode is available.
6.5 BARCODE ONLY MODE
In barcode only mode, it is still possible to enter a row via the keypad but all
other entries, including task selection, must be made via the keypad.
Barcode only mode is indicated on the screen via BC in the top right
corner.
To activate/deactivate the barcode only mode the 0 and 2 keys should be
held down while the start - up screen is shown (see section 2).
6.6 SUN SHIELD
For scanning in high ambient light environments, such as the glasshouse,
the barcode labels should be fitted in the optional sun shields. It is also
recommended that the sun shields should be used wherever possible as
they also act as a guide to correctly position the terminal which minimises
time lost to operators not correctly aiming their terminal.
7. ERROR MESSAGES
7.1 C LOCK NOT SET
If the internal clock has not acquired the current time from the NOMAD
system then an error message will be displayed CLOCK NOT SET . If this
message is displayed ensure that the terminal is within range of a link unit to
allow the terminal to acquire the time. Once the time is acquired the internal
clock of the terminal will maintain the time until power is lost.
