•  In general, maintenance on this product should only be performed by your installer, distributor, 

or ITL. 

•  Ensure that anyone performing maintenance on the unit is thoroughly familiar with its operation. 

•  The crane’s power sources should be shut off before any maintenance begins, unless absolutely 

required for troubleshooting the unit. When the power to the crane is on, use extreme caution. 
High voltage or unexpected movement of the crane can cause death or severe injury. 

•  Fall prevention devices should be used when anyone is working on the crane at an elevated 

height. 

•  Only ITL-certified maintenance personnel should attempt a repair more involved than the 

swapping of printed circuit boards. Improper repair can compromise the built-in safety features 
and can cause unexpected operation and damage. 

•  This product uses four AA alkaline batteries. When replacing batteries, all four must be replaced 

at the same time. 

•  ITL does not recommend use of nickel-cadmium batteries due to voltage characteristics that 

cause a sudden loss of power when discharged. They also have less capacity than AA alkaline 
batteries. 

The F22 Series Industrial Radio Remote Controller is equipped with a self-diagnostic program. If a 
malfunction is detected during the operation of the equipment, the system will sound an alarm on 
the receiver to indicate a receiver malfunction, or a buzzer on the transmitter to indicate a transmitter 
malfunction.  If this occurs, review Chapter 6 of the Operator’s Manual, “Basic Troubleshooting.” 

1.  Unscrew the cover of the battery compartment. 
2.  Remove and discard the old batteries. 
3.  Install 4 new AA alkaline batteries into the battery compartment, noting the polarity markings. 
4.  Replace the cover of the battery compartment. 
5.  Confirm proper installation:  If the batteries were installed correctly, the transmitter will beep 

twice.  If the transmitter does not beep twice, check battery polarity.
