2 Retain instructions

- The safety and operating instructions should be retained for future reference.

3 Heed Warnings 

- All warnings on the product and in the operating instructions should be adhered to.

4 Follow Instructions

- All operating and use instructions should be followed.

5 Cleaning

- Unplug this product from the wall outlet before cleaning. Do not use liquid cleaners or aerosol cleaners.

Use a damp cloth for cleaning.

6 Attachments

- Do not use attachments not recommended by the product manufacturer as they may cause

hazards.

7 Water and Moisture

- Do not use this product near water-for example, near a bath tub, wash bowl, kitchen sink,

or laundry tub; in a wet basement; or near a swimming pool; and the like.

8 Accessories

- Do not place this product on an unstable cart, stand, tripod, bracket, or table. The product may fall,

causing serious injury to a child or adult, and serious damage to the product. Use only with a cart, stand, tripod,

bracket, or table recommended by the manufacturer, or sold with the product. Any mounting of the product should

follow the manufacturer’s instructions, and should use a mounting accessory recommended by the manufacturer.

A product and cart combination should be moved with care. Quick stops, excessive force, and uneven surfaces

may cause the product and cart combination to overturn.

10 Ventilation

- Slots and openings in the cabinet are provided for ventilation and to ensure reliable operation of

the product and to protect it from overheating, and these openings must not be blocked or covered. The openings

should never be blocked by placing the product on a bed, sofa, rug, or other similar surface. This product should

not be placed in a built-in installation such as a bookcase or rack unless proper ventilation is provided or the

manufacturer’s instructions have been adhered to.

11 Power Sources

- This product should be operated only from the type of power source indicated on the marking

label. If you are not sure of the type of power supply to your home, consult your product dealer or local power

company. 

Main Power Disconnect;

When the power switch is in the Off position, the amplifier is not completely

disconnected from the main power.  The primary method of isolating the amplifier from the mains supply is to

disconnect the mains plug. Ensure that the mains plug remains accessible at all times. When installing the

product, ensure that the plug is easily accessible.

Non-use Period;

Unplug the AC power cord from the AC outlet if the unit will not be used for a long period

of time such as several months or more.

CLASS 1 Products;

The M25 shall be connected to a 

MAINS

socket outlet with a protective earthing connection.

12 Power-Cord Protection

- Power-supply cords should be routed so that they are not likely to be walked on or

pinched by items placed upon or against them, paying particular attention to cords at plugs, convenience

receptacles, and the point where they exit from the product.

13 Outdoor Antenna Grounding

- If an outside antenna or cable system is connected to the product, be sure the

antenna or cable system is grounded so as to provide some protection against voltage surges and built-up static

charges. Article 810 of the National Electrical Code, ANSI/NFPA 70, provides information with regard to proper

grounding of the mast and supporting structure, grounding of the lead-in wire to an antenna discharge unit, size of

grounding conductors, location of antenna discharge unit, connection to grounding electrodes, and requirements

for the grounding electrode.

NOTE TO CATV SYSTEM INSTALLER

This reminder is provided to call the CATV system installer’s attention to Section 820-40 of the NEC which

provides guidelines for proper grounding and, in particular, specifies that the cable ground shall be connected

to the grounding system of the building, as close to the point of cable entry as practical.

14 Lightning 

- For added protection for this product during a lightning storm, or when it is left unattended and

unused for long periods of time, unplug it from the wall outlet and disconnect the antenna or cable system. This

will prevent damage to the product due to lightning and power-line surges.

15 Power Lines

- An outside antenna system should not be located in the vicinity of overhead power lines or other

electric light or power circuits, or where it can fall into such power lines or circuits. 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.

16 Overloading

- Do not overload wall outlets, extension cords, or integral convenience receptacles as this can

result in a risk of fire or electric shock.

17 Object and Liquid Entry

- Never push objects of any kind into this product through openings as they may touch

dangerous voltage points or short-out parts that could result in a fire or electric shock.  Never spill liquid of any kind

on the product.

WARNING

18 Transportation

- Transport the amplifier in both inner and outer shipping containers.  Do not transport the

amplifier using one shipping container; to do so may result in damage to either the amplifier or personnel.
