GETTING STARTED
2.1 INSTALLING AND REMOVING THE MODULE
The HP-71 Data Acquisition Pac ROM module can be plugged into any of the four ports on the front
edge of the HP-71B Handheld Computer.
CAUTION
¢ Do not place fingers, tools, or other objects into the plug-in ports. Damage to plug-in module
contacts and the computer's internal circuitry may result. Such actions could result in minor
electrical shock hazard and interference with pacemaker devices worn by some persons.
e Turn off the computer (press [f JOFF]) before installing or removing a plug-in module.
eo If a module jams when inserted into a port, it may be upside down. Attempting to force it
further may result in damage to the computer or the module.
e¢ Handle the plug-in modules very carefully while they are out of the computer. Do not insert
any objects in the module connector socket. Always keep a blank module in the computer
port when a module is not installed. Failure to observe these cautions may result in damage to
the module or the computer.
To insert the module, hold the HP-71 with the
keyboard facing up and the module with the label
facing up. Push the module into the port until it
snaps into place. Be sure to observe the precautions
described above.
