|
7. |
Hearing Protection & R. Noise Measurement Set |
Combine for use with the Model-170A mainframe , to test the characteristic for the hearing protection and receiving residual noise of the telephone. ( See " Note " please ) |
|
|
9. |
X-Y Mouse |
Mouse |
Replace the upward, downward, leftward, rightward and enter keys on the keyboard. |
|
10. |
HP Printer ( Option) |
Printer (All the HP DeskJet or HP Laser Printers that are supported by DOS can all be used.) |
Print out the tested results & data. |
|
Note : GM-2 is used for testing the hearing protection and receiving residual noise , Some countries like Germany, England, Australia and New Zealand etc. required this kind of testing, If not require the testing for the hearing protection and receiving residual noise , then, GM-2 is not needed. |
