12. CLEANING

The equipment should be cleaned only as detailed in the operating instructions.

13. OBJECT AND LIQUID ENTRY

Care should be taken so that objects and/or liquids, such as cleaning fluids or beverages, are not spilled into the enclosure of the equipment.

14.DAMAGE REQUIRING SERVICE

Hafler equipment should be serviced by qualified service personnel when: A. The power supply cord or plug has been damaged, or

B . Objects have fallen, or liquid has been spilled into the equipment, or C . The equipment has been exposed to rain, or

D . The equipment does not appear to operate normally or exhibits a marked change in performance, or E . The equipment has been dropped, or the enclosure has been damaged.

15.SERVICING

The user should not attempt to service the equipment beyond that which is described in the operating instructions. All other service should be referred to qualified service personnel.

16. CARTS AND STANDS

The equipment should be used with carts or stands only of sufficient strength and stability for the use intended.

An equipment and cart combination should be moved with care. Quick stops and starts, excessive force, and uneven surfaces may cause the equipment and cart combination to topple.

17.POWER LINES

An outdoor antenna should be located away from power lines.

18.OUTDOOR ANTENNA GROUNDING

If an outside antenna is to be used with the Hafler Tuner, be sure that the antenna system is grounded so as to provide some protection against voltage surges and built up static charges. Section 810 of the National Electrical Code, ANSI/ NFPA No. 70-l 984, provides information concerning supporting structure, grounding of the lead-in wires to an antenna discharge unit, size of grounding conductors, location of antenna discharge unit, connections to grounding electrodes, and requirements for the grounding electrode. See Figure 1.
