laboratory conditions, but the actual SAR level of the transceiver while operating can be well below this value
This is because the transceiver is designed to use the minimum power required to reach the network.

implanted equipment. If a minimum distance of 15 cm (6 inches) is maintained between the GR64 module’s
radiating antenna and a pacemaker, the risk of interference is limited. If the integrator’s application is likely
to be situated in the vicinity of personnel, a suitable warning should be contained in the equipment manual to
this effect.
