HANDLING
This chapter describes the handling instructions, nomenclature, and maintenance of the PU.
4.1 Handling Instructions
( 1 ) Do not drop or subject to shock.
( 2 ) Do not disassemble the case.
(3) When the PU is not in use or the PU is connected t o the CPUvia a cable, f i t the protective cap on to
the connector.
(4) Do not touch the connector pins of the PU.
(5j Do not open the ROM cartridgecontainer
and donot
remove the ROM cartridgelocatedinside.

4.3 Maintenance
The PU has no special components which require inspection or replacement.
When keeping the PU in storage, take care of the following points:
( 1 ) Avoid storing the PU in the following environments:
1) Ambient
temperature is outside the range -1OOC to 50°C.
2) Ambient humidity i s outside the range 10 to 90%RH.
3) Condensation occurs due to sudden temperature changes.
4)
5)
Anywhere that the PU may be subjected to wind and rain or the direct rays of the sun.
Anywhere that there areexcessive amounts of conductivepowders, such as dust, dirt, and iron
filings, or corrosive gases, oil mist, salt, etc.
(2) Ensure that the audio cassette manual is fully understood before use.

5.2 Connecting and Disconnecting t o and from the A Series CPU
The PU canbe connected and disconnected to and from the PC while it is running. If possible,however,

For the read or verify operation, s e t the volume of the audio cassette to maximum. (Refer to Appendix

For the selection of tape recording time, refer to the list of processing times in the Appendix.
Normal domestic cassettes may be used-however those sold for home computer useare recommended.
A tape recorded with the AGPU can be replayed to the CPU via the A7PU.
If device memory data recorded from the AOJ2CPUP23/R23 is replayed to the AOJ2CPU, verify error
will occur. If device memory data recorded from the AOJ2CPU is replayed to the AOJ2CPUP23/R23,
link register contents will be lost.
