IMPORTANT SAFETY INSTRUCTIONS
For your safety, it is important to read and follow these instructions before
operating the FOR-22 4-wire/radio interface:
(1) WARNING: To reduce the risk of fire or electric shock, do not expose the
FOR-22 4-wire/radio interface to rain or moisture. Do not operate the FOR-22
near water, or place objects containing liquid on it. Do not expose the FOR-22
to splashing or dripping water.
(2) For proper ventilation, make sure ventilation openings are not blocked.
Install the FOR-22 according to the directions in the Installation Chapter of this
manual.
(3) Do not install the FOR-22 near a heat source such as a radiator, heat register,
stove, or other apparatus (including amplifiers) that produces heat. Do not place
naked flame sources such as candles on or near the FOR-22.
(4) Do not defeat the safety purpose of the polarized or grounding-type plug. A
polarized plug has two blades, with one blade wider than the other. A
grounding-type plug has two blades and a third grounding prong. The wide
blade or the third prong is provided for your safety. If the provided plug does not
fit into your outlet, consult an electrician for replacement of the obsolete outlet.
(5) Protect the power plug from being walked on or pinched particularly at
plugs, convenience receptacles, and the point where they exit from the i-station’s
chassis.
(6) Only use attachments/accessories specified by Clear-Com Communication
Systems.
(7) Unplug the FOR-22 during lightning storms or when unused for long
periods of time.
(8) Refer all servicing to qualified service personnel. Servicing is required when:
•The FOR-22 station has been damaged in any way, such as when a
power-supply cord or plug is damaged.
•Liquid has been spilled or objects have fallen into the FOR-22.
•The FOR-22 has been exposed to rain or moisture.
•The FOR-22 does not operate normally.
•The FOR-22 has been dropped.
Please familiarize yourself with the safety symbols in Figure 1. When you see
these symbols on the FOR-22, they warn you of the potential danger of electric
shock if the station is used improperly. They also refer you to important
operating and maintenance instructions in the manual.
Please read and follow these
instructions before operating
the FOR-22 4-wire/radio
interface.
