Wiring Diagram
(1)Take apart your local PSTN connecting line from the phone or switchboard, and
connect it to the LINE connecting slut of MT-350. If you use MT-350 to send and
receive calls only, then you don’t need to connect the local PSTN line.
(2)Connect PHONE connecting slut to the inlet side (Telephone Office) of phone or
switchboard.
(3)Put in transformer power. The DC end connects to DC 12V of MT-350, and then the
PW lamp on the front side of MT-350 should light up.
(4)MT-350 will proceed with system detection after booting. Please connect the Line
and Phone correctly before energizing it. If problem is found during the system
operation, please take power source off first and process wiring task next.
