Data Communication Precautions
The following explains important points to note during data communication,
and provides details about communication error messages.
Important!
• Keep the watch and the other device perfectly still during data communication.
• Do not allow anything to break the path between the two infrared ports
during data communication.
• Infrared communication may not be possible outdoors or in other areas
exposed to bright light. Best results are obtained under indoor lighting of
500 lux.
• The two infrared ports should be oriented so they are no more than 20cm
from each other, and are at an angle of less than 30 degrees from each other.
• Data communication at an angle greater than 15 degrees may be possible if
the two infrared ports are moved closer to each other.
• Proper infrared communication may be impossible if the two infrared ports
are too close to each other.
• You may need to position the infrared ports closer together when
transferring large volumes of data, when performing data transfer in an area
that is relatively hot, or when watch battery power is low.
• A separate nearby infrared data transfer operation can interfere with the
data communication operation of this watch.
• When positioning the watch for infrared data communication, make sure
you fold the band snugly underneath the watch case as shown in the
illustration.
Memory Capacity
Watch memory can hold a total of 24 Kbytes of data. Memory is shared
between the Contact, Schedule, To Do, User, and Browser Modes. The
following table shows how many data items (records, appointments, tasks, or
pages) can be stored in each mode under various data conditions.
• The maximum capacity is 16 Kbytes for the Contact Mode, and 8 Kbytes for
other modes.
• Note that the memory capacities in the table below are based on the
premise that there is no data stored in any of the other modes.
• The capacity of the Browser Mode is 8,100 characters when there is a
äWATCHäPAGE only (no user pages). If there is no data in the
äWATCHäPAGE, there can be up to 30 user pages in memory.
User Page title: 4 characters (24 bytes)
Text: Six lines with 30 characters each (192 bytes)
Each page title requires a minimum of eight bytes, plus the memory used
for input characters. The above values include these minimums.
The actual number of allowable user pages depends on the number of lines
of text in each page.
• There can be only one set of User Mode data in memory.
Precautions when Exchanging Data with an M-1510 Watch
• This watch can receive Telememo Mode index data from an M-1510 Watch.
Received index data is stored in the Contact Mode before the
äWATCHä index.
• This watch does not display a category icon for Schedule records received from
an M-1510 Watch. When you send a Schedule record from this watch to an M-
1510 Watch, the M-1510 Watch displays a category icon that looks like
.
• When you send an All Day Event Schedule record to an M-1510 Watch, the
M-1510 automatically adds a time of 12:00 before storing the data. Or if you
originally input and later deleted a time when inputting the record, it
automatically adds the time you originally input. Note that the M-1510
schedule reminder alarm also sounds in accordance with the automatically
added time.
• When this watch receives a To Do record from an M-1510 Watch, this
watch does not display a category icon or time (hour, minutes) for the
record. When you send a To Do record from this watch to an M-1510
Watch, the M-1510 displays a category icon that looks like
, and a time of
xx:xx.
• When this watch receives Browser data that includes indexes from an M-1510
Watch, this watch does not display the indexes.
• Any character sent from an M-1510 Watch or downloaded from your
computer that is not supported by this watch is replaced by
ã.
Data Communication Errors
The following describes error messages that can appear during data
communication, and what you should do to correct them.
Message Meaning
MODEL ERROR! The software installed on the computer
does not support data communication with
this watch.
TRANSFER ERROR! The path between the infrared ports is
blocked, the watch was moved, or some
other external influence is interfering with
proper data communication.
DATAFULL ERROR! The receiving watch memory is full.
ERROR! Any communication error other than the
above.
