Survey PAC Program
Message #1 Posted by Annie on 6 Feb 2006, 5:11 p.m.

Posting for customer:

When I turn on last week my HP41C on disply I saw: "BAT. LOST MEMORY". After replacing the batteries, all stored "HP SURVEY PAC" program lost. When I was trying to re-load, for instance:

EXC ALPHA SIZE ALPHA 005 (following Survey Pac)

EXC Alpha Curve Alpha

100 R R/S

I noticed on disply: SIZE 0... or CURVE what is not according to the Survey PAC.

I would greatly appreciate you suggestion and advice. I am unable to dowload any Survey PAC program.The Survey Module is in and before replacing batteries everything was OK.

The Lewis and Lewis is unable to fix up , because the HP 41 C is too old, nor other survey repair companies have any advice.

Thank you for your precious time and consideration.
