RF emissions (CISPR 11)
Group 2
The Surgitron
®
Dual/EMC must emit electromagnetic energy
in order to perform its intended function. Nearby electronic
equipment may be affected.
CISPR Emissions Classification
Class A
The emissions characteristics of this equipment make it
suitable for use in industrial areas and hospitals (CISPR 11
Class A). If it is used in a residential environment (for which
CISPR 11 Class B is normally required) this equipment might
not offer adequate protection to radiofrequency communication
services. The user might need to take mitigation measures,
such as relocating or re-orienting the equipment.

Mains power should be that of a typical
commercial or hospital environment. If
user requires continued operation during
power mains interruptions insure that
batteries are installed and charged.
Insure that battery life exceeds longest
anticipated power outages or provide and
additional uninterruptible power source.
