NOTES ABOUT DATAPAKS
There are two solid-state drives for datapaks in the back of
your Organiser. (See Figure 1.1. and
1.2.) When you first purchase your Organiser, drive number
one contains a real datapak. A dummy datapak is fitted in drive
number two to protect the electrical connectors. For the same
reason you should always keep a real or dummy datapak (or a
program pack) in each drive.
Changing A Datapak
Always switch off your Organiser before you remove or fit a
The datapaks slide into and out of their drives, and have an
easy-grip outer surface. Take care not to press the ON/CLEAR key
when removing or fitting a datapak. (This is easily avoided by
laying the machine face down on a flat surface, since the keyboard
is slightly recessed.) Simply press down and out on the ribbed
portion of a datapak to slide out of its drive. To fit a datapak,
push it into the required drive until you feel it click home.
Use the white label on your datapak to mark it for
The 'SAVE' and 'FIND' activities can be directed at either of
the datapak drives and the number of the target drive is shown in
the activity indicator, i.e. 'FIND1:', 'FIND2:', 'SAVE1:' and
'SAVE2:'. To move from 'FIND1:' to 'FIND2:' press the FIND key
again. If you press FIND repeatedly, Organiser selects datapak
drives one and two alternately. Similarly for save: Organiser
checks which datapak drives contain datapaks, and only offers
Once you have used a particular drive, the Organiser assumes you
want to continue using the same one until you select the other
drive or switch off.
Re-Using A Datapak
Although datapaks store your information permanently, it is
possible to clear an entire datapak using a special process called
formatting. This is achieved by controlled exposure of the datapak
in ultra-violet light in a purpose-built machine, the Psion
Formatter. The reformatted datapak will be completely blank and
read fur re-use. Note that the white label on the underside of each
datapak is to protect it from excessive exposure to light and must
be removed before formatting can occur.
Copying Between Datapaks
You may wish to copy a record from one datapak to another.
Perhaps you are passing on an address to a friend, reorganising
your data storage or preparing to re-use a datapak.
To copy a record, fit the two datapaks, find the record in one
and save it to the other. For example: Imagine you have a record in
the datapak in drive one which you want to copy into the datapak in
drive two. Press FIND to make 'FIND1:' appear. Now find your record
in the normal way. When it is displayed, press SAVE until 'SAVE2:'
appears to the left of your record. Press EXECUTE to save the
record in the datapak in drive two. The copying process is now
complete. You will be able to do this with all your record except
those you have erased.
You may wish to transfer your record from the original datapak
into a new one of equal or greater storage capacity. If your
original datapak contains any erased records, you will save space
by this process because erased records will not be transferred.
If you want to copy all records in one datapak into another, set
the Organiser to 'FIND1:' and 'SAVE2:' or vice versa before you
start so that it automatically chooses the correct datapak each
time you find or save a record.
For example, to copy all the records from the datapak in drive
one to the datapak in drive two, press FIND until 'FIND1:' appears,
then SAVE until 'SAVE2:' appears. Now, press FIND, EXECUTE, SAVE,
EXECUTE and repeat this sequence until you return to the first
record. (Remember to note the first record you copy.)
When a datapak is too full to accept the text you are trying to
save, Organiser displays the message " DATAPAK FULL" . To
make any more records you need another datapak. Your Organiser is
originally fitted with an eight kilobyte (8K) datapak, which can
hold 10.900 characters, but you can buy datapaks with greater
This message means the Organiser is having a difficulty
accessing the datapak. You should not see it unless your datapak
has suffered physical damage. The only likely exception is if you
have tried to save after receiving the " BATTERY LOW"
message in which case you will be able to find the existing
records, but no more can be saved on this datapak. It is advisable
to transfer the records into another datapak. The corrupted datapak
can then be reclaimed in a Psion Formatter.
Pressing ON/CLEAR clears such error messages so that you can
HINTS ABOUT RECORDS
When you are entering information you want to save, think about
finding it and structure it to give maximum retrieval efficiency.
Points to remember:
- Include the word that you will most likely want to use as a
search clue. (For instance, if you record the name and phone number
of a good local plumber, include the word 'plumber' so you can find
his phone number when you need him, although you've forgotten his
- When a record is recalled, you see its first
sixteen characters immediately and because you scan it backwards,
its last few characters are instantly accessible too. Use both
groups for the information you will need most often, remembering
that you need to know quickly which record you have found. (For
instance, if you are looking up your personal classification of
all the hotels you know in a certain town, you will probably see
your comment immediately, and if that is favourable, flick back
to see the phone number.
- If you want to categorise several records, which do
not share an obvious search clue, so that you can retrieve them
as a list, preface each one with the same unusual character
series. (For instance, when you are entering records of things
you must do this month, you could start them all with QDQ.)
- The answer to a calculation can only be saved if you edit it.
You could usefully do this by adding a label, to give it a
meaningful identity. For example, supposing you have calculated the
floor area, in square yards, of a kitchen which measures 15 feet by
12 feet, and 'CALC:15*12/9=20' is displayed. You might, for
instance, edit the result to add the label 'KITCHEN FLOOR' at the
beginning and 'SQ YDS', or whatever abbreviation you prefer, at the
Now you can save the information and be able to find it easily when
you need it. If you had several records of floor area you could
enter 'FLOOR' or 'SQ' or 'YDS' as a search clue to find them all in
a quick succession. To find the kitchen area in particular, it
would be quicker to search for '*KITCH'.
If you cannot see anything in the display when you switch on,
follow these steps until something appears in the display:
- Adjust the contrast control over the full range.
- Disconnect battery, reconnect securely and try again.
- Try a new battery.
- Remove any datapaks and start again.
No Response To Keyboard
If the display is alright but the keys seem to have no
- Make sure that you are not trying to type more than two hundred
characters on a line.
- Press ON/CLEAR a few times and try again.
- Disconnect the battery, wait for one minute and then reconnect
