Outer electromagnetic rays may interfere with the equipment via radiation or conduction. Some protection
actions should be taken:
1) Use only single-phase 3-line alternating current power socket with the PE line installed well so
that the filter circuit in the equipment works normally to filter the interference that come from the
electricity network.
2) Keep the equipment out of the radio transmitters and radar transmitters with high transmission
power and high frequency large current equipments.
3) Use electromagnetic shielding methods when necessary. For example use the shielded cables.
4) The cables should distribute inside the office room so as to protect the equipment from being
damaged by high voltage and current caused by thunder. Distributing the cables outside is
strongly discouraged.
3.2 Swift dial
Since GSM call is one time send number, it will send number after receive all numbers. S1801FG will treat
has received all numbers and send number after stop dial 5s. Also add “＃” can treat as received numbers,
then no need wait 5s to send numbers.
3.3 Connect Fax machine
