may also be pressed before communication is started between the Base Unit
and the meter. The meter, base unit and Application Program all have ample
delays built in to allow the other link components to come online in any
sequence.

TROUBLESHOOTING THE IR LINK :
Most problems tend to occur due to the positioning of the meter relative to the
base unit. There are a few error messages that may appear on the meter’s
screen:
a. Timeout: This error message occurs when too much time has passed
between data sent by the meter and the response that should have been
received from the base unit. Possible causes:

Meter misalignment with the Base Unit (make sure the communication
windows are facing each other, within the distance indicated).

No connection to the PC. The Base Unit must be connected to the PC
through a USB cable. Check connection.
b. KBD: This message occurs when the user presses a key during
communications. Do not push any key on the meter during data transfer. The
meter interprets this as a request to escape this activity and returns to the
Main Menu. The base unit should return to a green LED status in a few
seconds. A message should appear on the PC screen as well, indicating lost
communications.
c. Sync: This message occurs when data framing is lost during data
transmission. This would only happen if the wireless link becomes unreliable.
Ensure the meter and base unit are aligned and restart the session.
d. Data E: This message occurs when the content of a correctly framed data
packet is invalid. Again, this is an unreliable wireless link problem.
NOTE: Individual records cannot be downloaded to the PC. The entire
storage content is delivered to the PC during a link session.
SETUP MENU:
The Setup group of features allows access to the configurable parameters of the meter.
They are: Date and Time, Power-off time, Backlight, and Conversions (temperature
mode and electrode type). All can only be accessed in the Setup Menu. To get to the
Setup Menu, use the
 keys to highlight option #6: SETUP.
