CAUTION:
The R300 Communicator and Interconnect units contain auto-ranging power
supplies (100 – 240 Vac, 50 – 60 Hz) and require 3 amps maximum current a piece.
The AC power source can be 1 phase of 120 Vac with neutral (100 Vac for Japan)
with a 15 amp circuit breaker, or 1 phase of 220 or 240 Vac (200 Vac for Japan) with
a 10 amp circuit breaker. A single, dedicated AC branch can service both the R300
Communicator and Interconnect units. These units require a three-wire AC cord
