MD Evolution – Cordless DT412 / DT422 / DT432 16
Although the SAR is determined at the highest certified power level,
the actual SAR level of the phone while operating can be well below
the maximum value. This is because the phone is designed to
operate at multiple power levels. Before a phone model is available
for sale to the public, it must be tested and certified to the FCC that
it does not exceed the limit established by government-adopted
requirement for safe exposure. The tests are performed in positions
and locations (for example, at the ear and worn on the body) as
required by the FCC for each model.
While there may be differences between the SAR levels of various
phones and at various positions, they all meet the government
requirement for safe exposure.
For body worn operation, to maintain compliance with FCC RF
exposure guidelines, use only approved accessories. When
carrying the telephone while it is on, use only the specific belt clip
that has been tested for compliance.
Use of non-approved accessories may violate the FCC RF
exposure guidelines and should be avoided.
This device has been shown to be capable of compliance for
localized specific absorption rate (SAR) for uncontrolled
environment/general population exposure limits specified in ANSI
IEEE Std. C95.1-1992 and had been tested in accordance with the
measurement procedures specified in FCC/OET Bulletin 65
Supplement C (2001) and IEEE Std. 1528- 2003 (December 2003).
Most modern electronic equipment (for example, equipment in
hospitals and cars) is shielded from RF energy. However, RF energy
from cordless telephones may affect some electronic equipment.
Chemical Resistance
The alpha and numeric characters printed on the exterior of the
cordless telephone have been tested and found resistant to
chipping, fading or wearing off when the telephone is treated with
common cleaners and disinfectants or perspiration.
The following chemicals have shown no harmful effect:
•
3% Hydrochloric Acid
• M-alcohol (70% Methylated Ethanol)
• 60% Chlorhexidin 0.5mg/ml
Important: Acetone can be damaging to the plastic casing
of the cordless telephone and should not be used.
