Power Supply
Must be regulated and ripple free. It is not advisable to use a switched mode power supply, either to drive the
X7000 Modem or within close proximity to it. Switched mode power supplies can produce high energy radio
frequencies over a broad spectrum potentially causing interference with the operation of the Modem.
Note : If the direct modulation input is used (MIN) then the radio and the users modulation circuit must be
submitted for MPT1329 type approval.
Channel Selection
Channel selection may be effected by either the 5DIL switches, Single step, or via the serial data
communication.
