Service and Warranty


Low Power
All decimal points light to warn you that you have 2 to 5 minutes of operating time left. You must then either:
  Operate from ac power
  Charge the battery pack
  Insert a fully charged battery pack

Blank Display

If the display blanks out, turn the HP-80 off then on. If 0.00 does not appear on the display, check the following:
1. If battery charger is attached to HP-80, make sure it is plugged into outlet.
2. Examine battery pack to see if it is discharged or is not making contact.
3. If display is still blank, try operating the HP-80 from the ac line.
4. If display is still blank, the HP-80 is defective (see warranty section).


In Warranty
The HP-80 is warranted against defects in materials and workmanship for one year from date of delivery. During the warranty period we will repair or replace components that prove to be defective, provided they are returned to Hewlett-Packard according to instructions (see Shipping Instructions). No other warranty is expressed or implied. We are not liable for consequential damage.
Out of Warranty
Beyond the one year warranty period, your calculator will be repaired for a moderate charge. Return the HP-80 along with all standard accessories (see Shipping Instructions). If only the battery pack is defective, simply order a replacement on the Order Card provided.
