mobile RF communications equipment (transmitters) and the Merlin PCS as recommended
in the table below, according to the maximum output power of the communications
equipment. For transmitters rated at a maximum output power not listed in the table below,
the recommended separation distance (
d) in meters can be estimated using the equation
applicable to the frequency of the transmitter, where
P is the maximum output power rating
of the transmitter in watts (
W) according to the transmitter manufacturer.

RF Operating Frequencies
Nearby or hidden equipment emitting strong magnetic fields, such as Radio-Frequency
Identification (RFID) emitters, other medical and radio devices, etc., can interfere with the
Merlin™ PCS inductive and RF communication, even if the other equipment complies with
applicable emission requirements. If interference occurs, you can minimize its effect by
reorienting or relocating the Merlin PCS or by shielding its location.
The operating characteristics of the Merlin PCS and its accessories are as follows:
Inductive Telemetry Wand
 RF Transmission – Carrier frequency below 100 kHz (inductive telemetry).
 RF Reception – Below 100 kHZ (inductive telemetry).
Merlin™ Antenna
 MICS band: 402-405 MHz. The effective radiated power is below the limits as specified in:
- Europe: EN ETSI 301 839
- USA: FCC 47 CFR Part 95; 95.601-95.673 Subpart E, 95.1201-95.1219
The following is applicable to Canada only:
This device may not interfere with stations operating in the 400.150-406.000 MHz band in the
meteorological aids, meteorological-satellite, and earth exploration-satellite services and must
accept any interference received, including interference that may cause undesired operation.

These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from
structures, objects, and people.
18
At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
