Trouble inspection
If the “error lamp” on the receiver blinks in red, turn OFF the power once and turn it ON again
(turn ON the starter switch again).
If blinking of “error lamp” persists, repair is needed as the radio remote control device is in fail-
ure.
If a trouble is found in the radio remote control device, check the following then contact the
nearest UNIC authorized service shop.
Check if:
(1) Crane is controlled by manual levers.
(2) The “power lamp” on the transmitter lights. If it blinks or does not light, replace the batter-
ies in the transmitter.
(3) Switches and control levers on the transmitter make a correct operation.
(4) The stay on the transmitter (antenna is built in) has not been broken or deformed.
(5) The “mode indicator lamp” in the control box lights and the “power lamp” on
the receiver blinks in green when power to the control box is turned ON.
If the “mode indicator lamp” blinks, refer to section “18. Mode indicator lamp” (on
page18-1).
