Installing and Operating the PG 720
Caution
!
Risk of damage to EPROMs or EEPROMs!
If you insert or remove the EPROM or EEPROM while it is in use, there is a
danger that it will be damaged.
You must not remove the S5 EPROM or EEPROM while the LED indicating
that the EPROM or EEPROM is being read etc. is lit. You cannot work
simultaneously with S5 memory submodules and memory cards.
Before inserting or removing S5 EPROMs or EEPROMs, you must equalize
the static charge on your body with the potential on the unit. You can do this
by briefly touching the metal mounting plate of the ports on the left-hand
side panel of the unit.
