Certification
designed to provide reasonable protection against harmful interference when
the equipment is operated in a commercial environment. This equipment
generates, uses, and can radiate radio frequency energy and, if not installed
and used in accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this equipment in a
residential area is likely to cause harmful interference, in which case the user
will be required to correct the interference at his own expense. The following
techniques of reducing the interference problems are applied easily.
1. Disconnect the 980 Flow Meter from its power source to verify that it is or
is not the source of the interference.
2. If the 980 Flow Meter is connected into the same outlet as the device with
which it is interfering, try another outlet.
3. Move the 980 Flow Meter away from the device receiving the interference.
4. Reposition the receiving antenna for the device receiving the interference.
5. Try combinations of the above.
FCC Requirements
1. The Federal Communications Commission (FCC) has established Rules
which permit this device to be directly connected to the telephone
network. Standardized jacks are used for these connections. This
equipment should not be used on party lines or coin lines.
2. If this device is malfunctioning, it may also be causing harm to the
telephone network; this device should be disconnected until the source of
the problem can be determined and until repair has been made. If this is
not done, the telephone company may temporarily disconnect service.
3. The telephone company may make changes in its technical operations
and procedures; if such changes affect the compatibility or use of this
device, the telephone company is required to give adequate notice of the
changes.
4. If the telephone company requests information on what equipment is
connected to their lines, inform them of:
a. The telephone number that this unit is connected to,
b. The ringer equivalence number [1.4B]
c. The USOC jack required [RJ11C], and
d. The FCC Registration Number
Items (b) and (d) are indicated on the label. The ringer equivalence number
(REN) is used to determine how many devices can be connected to your
telephone line. In most areas, the sum of the RENs of all devices on any one
line should not exceed five. If too many devices are attached, they may not
ring properly.
