The lightning flash with arrowhead symbol
within an equilateral triangle is intended to

alert you to the presence of uninsulated
“dangerous voltage” within the product’s

enclosure that may be of sufficient

magnitude to constitute a risk of electrical

shock to persons.

The exclamation point within an equilateral

triangle is intended to alert you to the

presence of important operating and

maintenance (servicing) instructions in the

literature accompanying the product.

TO REDUCE THE RISK OF ELECTRICAL SHOCK, DO NOT REMOVE COVER

FROM THIS UNIT. NO USER-SERVICEABLE PARTS INSIDE.

REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.

WARNING: TO PREVENT SHOCK HAZARD, DO NOT EXPOSE THIS UNIT TO RAIN OR MOISTURE

NOTE TO CATV INSTALLERS

This reminder is provided to call the CATV System Installer’s attention to Article 820-40 of the NEC that provides guidelines for proper grounding and,

Safety Instructions

You should always follow these instructions to help ensure against injury to yourself and
damage to your equipment.

➧ Read all safety and operating instructions before you operate the modulator.
➧ Retain all safety and operating instructions for future reference.
➧ Heed all warnings on the modulator and in the safety and operating instructions.
➧ Follow all installation, operating, and use instructions.
➧ Unplug the modulator from the AC power outlet before cleaning. Use only a damp cloth for cleaning the exterior of the

modulator.

➧ Do not use accessories or attachments not recommended by Blonder Tongue, as they may cause hazards, and will void

the warranty.

➧ Do not operate the modulator in high-humidity areas, or expose it to water or moisture.
➧ Do not place the modulator on an unstable cart, stand, tripod, bracket, or table. The modulator may fall, causing serious

personal injury and damage to the modulator. Install the modulator only in a mounting rack designed for 19” rack­mounted equipment.

➧ Do not block or cover slots and openings in the modulator. These are provided for ventilation and protection from

overheating. Never place the modulator near or over a radiator or heat register. Do not place the modulator in an
enclosure such as a cabinet without proper ventilation. Do not mount equipment in the rack space directly above or
below the modulator.

➧ Operate the modulator using only the type of power source indicated on the marking label. Unplug the modulator power

cord by gripping the plug, not the cord.

➧ The modulator is equipped with a three-wire ground-type plug. This plug will fit only into a ground-type power outlet. If

you are unable to insert the plug into the outlet, contact an electrician to replace the outlet. Do not defeat the safety
purpose of the ground-type plug.

➧ Route power supply cords so that they are not likely to be walked on or pinched by items placed upon or against them.

Pay particular attention to cords at plugs, convenience receptacles, and the point where they exit from the unit.

➧ Be sure that the outdoor components of the antenna system are grounded in accordance with local, federal, and

National Electrical Code (NEC) requirements. Pay special attention to NEC Sections 810 and 820.

Safety Instructions - continued

➧ We strongly recommend using an outlet that contains surge suppression or ground fault protection. For added

protection during a lightning storm, or when the modulator is left unattended and unused for long periods of time, unplug
it from the wall outlet and disconnect the lines between the modulator and the antenna. This will prevent damage
caused by lightning or power line surges.

➧ Do not locate the antenna near overhead power lines or other electric light or power circuits, or where it can fall into

such power lines or circuits. When installing the antenna, take extreme care to avoid touching such power lines or
circuits, as contact with them can be fatal.

➧ Do not overload wall outlets or extension cords, as this can result in a risk of fire or electrical shock.
➧ Never insert objects of any kind into the modulator through openings, as the objects may touch dangerous voltage

points or short out parts. This could cause fire or electrical shock.

➧ Do not attempt to service the modulator yourself, as opening or removing covers may expose you to dangerous voltage

and will void the warranty. Refer all servicing to authorized service personnel.

➧ Unplug the modulator from the wall outlet and refer servicing to authorized service personnel whenever the following

occurs:

❐ The power supply cord or plug is damaged;
❐ Liquid has been spilled, or objects have fallen into the modulator;
❐ The modulator has been exposed to rain or water;
❐ The modulator has been dropped or the chassis has been damaged;
❐ The modulator exhibits a distinct change in performance.
➧ When replacement parts are required, ensure that the service technician uses replacement parts specified by Blonder

Tongue. Unauthorized substitutions may damage the modulator or cause electrical shock or fire, and will void the
warranty.

➧ Upon completion of any service or repair to the modulator, ask the service technician to perform safety checks to ensure

that the modulator is in proper operating condition.
