Use a dedicated battery to power the receiver / servo.
This receiver employs an electronic switching (current is controlled by an FET circuit)
system. When the exclusive switch is set to ON or is pulled, the power is turned on.
Switches other than the exclusive switch cannot be used. In addition, since a very

connector when the receiver is not in use.
One or 2 batteries can be connected. When 2 batteries are connected, the battery with
the highest voltage is used. When only one battery is connected, always insulate the
unused connector. The battery can be connected to either side.

The DLPH-1 is equipped with a telemetry sensor function. The receiver voltage displayed on the
transmitter home screen is only a constant value. The voltages of battery 1 and battery 2 should
be monitored by telemetry voltage.
DLPH-1 uses two continuous slots. Please note that the proper default start slot for this accessory
is number 6. When setup-changing or adding, it is the following numbers that are made to a start
1,2,3,4,5,6,8,9,10,11,12,13,14,16,17,18,19,20,21,22,24,25,26,27,28,29,30
By connecting the transmitter and SB2 port, it is possible to register to the transmitter and change
the start slot. In that case, it is necessary to connect the battery to DLPH-1 and supply power.
Information on how to change the slot assignment is included in the transmitter's manual.
