Any aplet can be copied from one hp 39g+ to another via the built in infra-red
link at the top of the calculator. Indeed it is not only aplets which can be
copied, but lists, notes, sketches, matrices and programs. Of the family of
related models, only the hp 40g does not have this capability.
The key to this ability is the presence of a
screen key labeled
and its companion
key
. This is shown in the APLET view on
the right.
The infra-red port
These keys can be used to send a copy of the highlighted aplet to any other
hp 39g+.
The infra-red link is located at the top of the calculator, next to the socket
which is used to connect the hp 39g+ to a computer. This link is exactly like
the remote control of a VCR, and allows two calculators to talk to each other.
In the interests of security in tests and exams, the distance over which they
can talk is limited to about 8-10cm.
If you look at the keyboard side of the calculator, near the “hp 39g+” label
above the screen, you’ll find a small white triangle. This marks the position of
the infra-red port so you can line them up when looking down from above.
Put the two calculators top-end to top-end and line up the arrows with the
calculators no more than 9-10 cm apart. The best separation is about 3 -4cm.
The instructions which follow apply to the
transmission of an aplet via the infra-red link
but the process is the same for any other view
which has
and keys. The only
difference is with the hp 40g, the version
available in Europe. For this calculator the link
is via a supplied calculator to calculator cable and you would choose
HP39/40 (Wire) instead of the HP39+ (IrDA) specified on the next page.
