Any combination of left or right and up or down can be used simultaneously. If the left
and right buttons are pressed at the same time, the monitor will stop all motion.
3) To open the water valve, push and release the valve open button. The valve will open
fully and remain open. To close the valve, push and release the valve close button. The
valve will completely close and remain closed. There is no need to wait for the valve to
fully open or close before reversing direction. The close button for the water valve on the
handheld will disengage the lock open feature of the primary transmitter and close the
water valve. This feature allows the operator to exit the vehicle with the water valve
locked open and operates the monitor via the handheld. When and if the operate
chooses to take over command of the water valve, a push of the close button releases
the “lock open” feature and transfers water valve control to the handheld.
4) The handheld transmitter has a power saving feature that turns the transmitter power
off if no signal is sent
for 5 minutes. Press and hold the “ON/OFF” button until the Power
LED illuminates to reactivate the transmitter. The “Low Battery” LED will flash slowly
when the battery voltage drops below a predetermined level. When the low battery LED
flashes rapidly, the batteries are nearly discharged and should be replaced immediately.
B. Oscillation Function
The 8494 RF monitor has an oscillation function, which can be used to provide
continuous exposure protection with no operator input. The oscillation limits are set using
either joystick or handheld transmitters. The motor two-speed feature is turned off during
oscillation and the monitor will oscillate back and forth at full speed.
Note: The oscillation travel limits must be within the programmed left/right rotation
envelope.
