antenna and the ME EQUIPMENT or ME SYSTEM
may be reduced to 1 m. The 1 m test distance is
permitted by IEC61000-4-3.
displayed, Replace with 2 new AAA batteries ,
slide open the battery cover and remove old
batteries.Replace the batteries being sure to align
properly as indicated inside the battery compart-
ment.
2.Remove the battery from the product if it is not
required for extended periods of time in order to
avoid damage to the thermometer resulting from a
leaking battery.
3.To protect the environment, dispose of empty
batteries at appropriate collection sites according
to national or local regulations.
Portable RF communications equipment
(including peripherals such as antenna cables and
external antennas) should be used no closer than
30 cm (12 inches) to any part , including cables
specified by the manufacturer. Otherwise,
degradation of the performance of this equipment
could result.
This equipment might not offer adequate
protection to radio-frequency communication
services. The user might need to take mitigation
measures, such as relocating or re-orienting the
equipment.
When the instrument is in use, never put it near

modulation at 18 Hz may be used because while it
does not represent actual modulation, it would be
worst case.
