battery power is sufficient. The LED will flash red when the battery
power is low, and it is required to replace with fresh batteries
immediately.
Receiver Power Supply
There are two type of receiver decoder/relays board for DC and AC
power supply.
A. The voltage range for the DC power supply is DC12 ~ 24V.

B. There are five different transformer with different voltages for the
AC power supply containing AC24/48, 48/110, 48/220, 110/220
and 220/380V, each transformer has two kind of voltage which will
be selected by a Jumper set at HI or LO position on the pc board as
shown on the following Fig.
4
Please find on the following, if the Jumper is set at HI position, the
voltages can be AC48, 110, 220, 220 or 380V; if the Jumper is set at
LO position, the voltage can be AC24, 48, 48, 110 and 220V.
