Speciﬁcations and Features

The FCC requires that the following statements be

includedinthismanualfortheSMVandSMQV:

For body worn operation, this transmitter models has

been tested and meets the FCC RF exposure guidelines

when used with the Lectrosonics accessories supplied or

designated for this product. Use of other accessories may

not ensure compliance with FCC RF exposure guidelines.

Contact Lectrosonics if you have any questions or need more

information about RF exposure using this product..

This device complies with FCC radiation exposure limits as

set forth for an uncontrolled environment. This device should

be installed and operated so that its antenna(s) are not co-

located or operating in conjunction with any other antenna or

transmitter.

Spurious radiation: 60 dB below carrier

Equivalent input noise: –125 dBV, A-weighted

Input level:

If set for dynamic mic: 0.5 mV to 50 mV before limiting.

Greater than 1 V with limiting.

If set for electret lavaliere mic: 1.7 uA to 170 uA before limiting.

(overall system, 400 Series mode)

(Note: the dual envelope “soft”

limiter provides exceptionally

good handling of transients

using variable attack and release

time constants. The gradual onset of limiting in the design begins below full

modulation, which reduces the measured ﬁgure for SNR without limiting by 4.5 dB)
