Theory of Operation

3.6

Mounting the unit

8742 may be set on a table top.
While not required, the 8742 can be bolted to the table top in either horizontal or

vertical orientation.
Under conditions of extreme usage, the case temperature of the Model 8742 may

exceed the levels considered safe by various international safety conventions. If

such use is anticipated, the user must position, or block access to, the unit so that the

unit cannot be accidentally touched.
