Time out
If you see a message saying that there has
been a “Time-out”, it may mean that you did
not line the calculators up precisely enough
or pressed on one without pressing
on the other. The first thing they do is
say the electronic equivalent of “Hi there” to
each other, and if there is no answer from the other machine within about 30
seconds, this is the message you receive.
Calculator Tip
The main cause of failure in communications is low
batteries. Low batteries affect communications long before
the warning symbol appears.
Attached programs
If your aplet is one that has been created by
someone else, rather than simply a copy of
one of the standard ones, then it will probably
have one or more ‘helper’ programs
associated with it. For example, almost all the
aplets available from the Hewlett-Packard web
site come with sets of up to 6 or 7 programs to do the work, and without
which they are totally useless. As an example, the screen shown right
contains a number of programs which belong to an aplet called “Coin
Tossing” which can be downloaded from the web site The HP HOME view (at
http://www.hphomeview.com).
Normally you do not need to worry about this, since the calculator knows they
belong with the aplet and will automatically transmit them with it. This can
often greatly increase the transmission time. If you want to see these ‘helper’
programs, press SHIFT PROGRAM to see a list of the programs currently on
your calculator. Even if there are no other
programs currently stored, you will always see
the ‘Editline’ entry. It contains a record of the
last calculation you did in the HOME view and
can’t be deleted.
