The most effective means of reducing interference to a minimum has been built into your Zenith Television receiver. Occasionally however, the picture may be affected by electrical interference or reflections.

Automobile ignition, electrical appliances, etc., cause a speckled streaked appearing picture as shown. This condition is most noticeable in weak signal areas. (Fig. 6.)

Diathermy produces a distinctive herringbone pattern and one or two horizontal bands across the face of the picture. (Fig. 7). It can sometimes be reduced or eliminated by the insertion of a filter trap at the antenna terminals.

Radio signals by a neighboring commercial, amateur or police station may cause interference in the form of moving ripples or diagonal streaks. Television or FM receivers operating near your receiver, can also be the reason for this reaction. (Fig. 8.)
The insertion of a filter trap at the antenna terminals of the TV receiver will sometimes eliminate or reduce this type of interference.		FIG. 8

An outdoor type antenna is recommended for best reception. If such installation is impossible, different type indoor antenna may be used. Quality of reception also depends upon local signal conditions.

Some models are equipped with a di-pole or mono-pole antenna mounted at the cabinet back. To use this antenna, raise and extend rods. Vary the length and position of the rods or rod for best picture and sound.

Under favorable receiving conditions, satisfactory reception may be obtained with a 10 ft. length of antenna wire. (Supplied with some models). Stretch out wire for best reception.

When using a regular outside antenna, disconnect the inside antenna leads from the antenna terminal screws. Connect the
