1. MAXIMUM PERMISSIBLE EXPOSURE (MPE)

1.1 Standard Applicable

According to §1.1307(b)(1), system operating under the provisions of this section shall be operating in a manner
that the public is not exposed to radio frequency energy level in excess limit for maximum permissible exposure.

(a) Limits for Occupational / Controlled Exposure

Electric Field Magnetic Field Averaging Times
Frequency range Power Density
Strength (E) Strength (H) | E |2, | H |2 or
(MHz) (S) (mW/cm2)
(V/m) (A/m) S (minutes)
0.3-3.0 614 1.63 (100)* 6
3.0-30 1842/f 4.89/f (900/f)* 6
30-300 61.4 0.163 1.0 6
300-1500 / / F/300 6
1500-100000 / / 5 6

(b) Limits for General Population / Uncontrolled Exposure

Electric Field Magnetic Field Averaging Times
Frequency range Power Density
Strength (E) Strength (H) | E |2, | H |2 or
(MHz) (S) (mW/cm2)
(V/m) (A/m) S (minutes)
0.3-1.34 614 1.63 (100)* 30
1.34-30 824/f 2.19/f (180/f)* 30
30-300 27.5 0.073 0.2 30
300-1500 / / F/1500 30
1500-100000 / / 1 30
Note: f = frequency in MHz: * = Plane-wave equivalents power density

1.2 MPE Calculation Method

S = (30*P*G) / (377*R2)
S = power density (in appropriate units, e.g., mw/cm2)
P = power input to the antenna (in appropriate units, e.g., mw)
G = power gain of the antenna in the direction of interest relative to an isotropic radiator,
the power gain factor is normally numeric gain.
R = distance to the center of radiation of the antenna (in appropriate units, e.g., cm)

1.3 MPE Calculation Result

Model No.: RM pro, RM 3, RM 3+, RM pro+, RM home, RM home+, RM pro B
FCC ID: 2ACDZ-RMPRO
Device category: Universal Remote

Maximum peak output power: 13.93 (dBm)
Maximum peak output power at antenna input terminal: 24.71(mW)
Prediction distance: >20(cm)
Prediction frequency: 2412 (MHz)
Antenna gain: 2.0 (dBi)
Directional gain: 1 (numeric)
The worst case is power density at prediction frequency at 20cm: 0.0077(mw/cm2)
MPE limit for general population exposure at prediction frequency: 1 (mw/cm2)

0.0077(mw/cm2) < 1 (mw/cm2)

So the transmitter complies with the RF exposure requirements and the SAR is not required.
