Battery Care
|
|
|
When not being used, the batteries in your HP-67 have a self-discharge rate of approximately 1 % of available
charge per day. After 30 days, a battery pack could have only 50 to 75% of its charge remaining, and the
calculator might not even turn on. If a calculator fails to turn on. you should substitute a charged battery
pack, if available, for the one in the calculator. The discharged battery pack should be charged for at
least 14 hours.

|
If a battery pack will not hold a charge and seems to discharge very quickly in use, it may be defective.
The battery pack is warranted for one year, and if the warranty is in effect, return t-e defective pack
to Hewlett-Packard according to the shipping instructions. (If you are in doubt about the cause of the
problem, return the complete HP-67 along with its battery pack and ac adapter/recharger.) If the battery
pack is out of warranty, see your nearest dealer or use the Accessory Order Form provided with your HP-67
to order a replacement.

Magnetic Card Maintenance
|
|
|
Try to keep your cards as clean and free of oil, grease, and dirt as possible. Dirty cards can only
degrade the performance of your card reader. Cards may be cleaned with alcohol and a soft cloth.
|
|
|
Minimize the exposure of your calculator to dusty, dirty environments by storing it in the soft
carrying case when not in use. Each card pack contains one head cleaning card.
