179Care & safety
Battery safety
• Always observe correct polarity of batteries (+ and -) when
inserting them.
• Dont store batteries at temperatures in excess of +60°C;
the optimum storage temperature for maximum battery life
is +10°C to +35°C.
• Dont dispose of batteries in a fire - there is a danger of
explosion.
• Dont crush, puncture, open, dismantle, or otherwise
mechanically interfere with batteries.
• If a battery should leak, do not allow the contents to come
into contact with your skin or your eyes. If it does, wash
immediately with plenty of cold water and seek medical
advice.
• If a battery has been accidentally swallowed, it is
ESSENTIAL that medical assistance is sought
IMMEDIATELY. If the small backup battery has been
swallowed, advise the medical person that a LITHIUM
battery is involved.
Caution:
There is a danger of explosion if the backup battery is incorrectly
replaced. Replace battery only with the same or equivalent type
recommended by Psion. Dispose of used batteries according to the
manufacturers instructions.
Prolonging battery life
You can take steps to help your batteries last longer:
• Turn off the remote link when not in use.
• Set Auto switch-off times for the machine and the backlight.
• Use Data and Agenda files on the Internal disk (C) instead
of a Memory disk (D), as the Series5 requires more power
to write to the Memory disk.
When your Series5 is switched off, it is on standby and will
continue to use a small amount of battery power, at a rate of
about 1% per day. If you are going to leave your Series5
switched off for a long period of time, you are advised to back
up your data beforehand as the batteries will eventually run out.
