User's Manual

- Ensure that anyone performing maintenance on the unit is thoroughly familiar
with its operation.
- Power should be shut off to the crane or equipment before any maintenance
begins, unless absolutely required for troubleshooting the unit. When the power
is on, use extreme caution. High voltage or unexpected movement could cause
death or severe injury.
- Only 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 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 or nickel-metal-hydride batteries
due to voltage characteristics that cause a sudden loss of power when discharged.
They also have less capacity than alkaline batteries and therefore will not last as
long.
