Radio Shack TRS-80 PC-3

• To transfer program and data from the tape, use the tape recorder with which the tape was prerecorded. A tape recorder, if
different from that used for recording, may cause no transfer of the prerecorded tape.
Care and Maintenance
*
Be sure that the power is OFF on both units when connecting or disconnecting the Printer/Cassette Interface and the
Computer.
* The Printer should be operated on a level surface.
* The unit should be kept away from extreme temperatures, moisture, dust, and loud noises.
* Use a soft, dry cloth to clean the unit. DO NOT use solvent or a wet cloth.
* Keep foreign objects out of the unit.
Errors
If the batteries become low, or if the Printer/Cassette Interface is subjected to strong noise, the unit may cease to function and the
Pocket Computer may "hang up". This can also occur if the units are connected and the power is not turned on the Printer/
Cassette Interface when a LPRINT or LLiST command is used. In some cases, ERROR 8 may be displayed on the Computer.
The CLear key may usually be used to clear this condition, but in some cases the ALL RESET may be required. Be sure to restore
adequate power to Printer/Cassette Interface before attempting to use it again.
