NordicTrack NTL21905.1 user manual

21.Inspect and properly tighten all parts of the treadmill every three months.

22.Never drop or insert any object into any open- ing.

23.DANGER: Always unplug the power cord immediately after use, before cleaning the treadmill, and before performing the maintenance and adjustment procedures de- scribed in this manual. Never remove the motor hood unless instructed to do so by an authorized service representative. Servicing other than the procedures in this manual should be performed by an authorized ser- vice representative only.

24.The treadmill is intended for in-home use only. Do not use the treadmill in any commer- cial, rental, or institutional setting.

25.If an outside antenna or cable system is con- nected, be sure that the antenna or cable sys- tem is grounded to provide some protection against voltage surges and built-up static charges. Section 810 of the National Electrical Code, ANSI/NFPA No. 70-1984, pro- vides information with respect to proper grounding of the mast and supporting struc- ture, grounding of the lead-in wire to an an- tenna discharge unit, size of grounding con- ductors, location of antenna discharge unit, connection to grounding electrodes, and re- quirements for the grounding electrode.

26.An outside antenna system should not be lo- cated in the vicinity of overhead power lines or other electric light or power circuits, or where it can fall into such power lines or cir- cuits. When installing an outside antenna system, extreme care should be taken to keep

from touching such power lines or circuits, as contact with them might be fatal.

27.To reduce the risk of electric shock, do not remove the cover or the back of the televi- sion. There are no user serviceable parts in- side. Refer servicing to qualified service per- sonnel.

28.Upon completion of any service or repairs to the treadmill or the television, ask the service technician to perform safety checks to con- firm that the unit is in proper operating con- dition.

•Use No. 10 AWG (5.3mm2) copper, No. 8 AWG (8.4mm2) aluminum, No. 17 AWG (1.0mm2) copper-clad steel or bronze wire, or larger as a ground wire.

•Secure an antenna lead-in and ground wires to the house with stand-off insulators spaced from 4 to 6 feet (1.22 to 1.83m) apart.

•Mount an antenna discharge unit as close as possible to where the lead-in enters the house.

•Use a jumper wire not smaller than No. 6 AWG (13.3mm2) copper, or the equivalent when a separate antenna-grounding elec- trode is used. See NEC Section 810-21 (j).

Note to CATV system installer: This reminder is provided to call the CATV system installer’s at- tention to Article 820-40 of the NEC that provides guidelines for proper grounding and, in particu- lar, specifies that the cable ground shall be con- nected to the grounding system of the building, as close to the point of cable entry as practical.
