DEC 4000 Model 200 - Setting the Write-Protect Tab on the Cassette Tape

3.1.4.2 Setting the Write-Protect Tab on the Cassette Tape
If you wish to read or copy from a tape, set the write-protect tab on the
cassette to write-protect. This disables writing to tape and ensures data
integrity. Use a pen (not pencil) to set the write-protect tab (Figure 3–14)
to the desired position.
Observe the following guidelines when setting the write-protect tab.
• If you are reading data (copying from tape), set the write-protect tab to
write-protected.
• If you are writing data, set the write-protect tab to write-enabled.
• Write-protect tab position displays in front panel tape indicator.
