Chapter 4 

At the start of each shift, perform the following 
safety checks: 
1.  Confirm that there is sufficient battery power 

to operate the transmitter:  If the LED color 
during the power-on procedure was green, then 
there is sufficient battery power to operate the 
transmitter.  If the LED color was yellow or 
red, then battery power is low and all four 
batteries should be replaced immediately.  See 
Table 4-1-3 below for more details. 

2.  Test the emergency stop function by pressing 

the red EMS button (shown in Figure 7).  A 
tone will sound and the LED will flash red and 
green alternately to indicate actuation of the 
emergency stop.  If this does not occur, do not 

use the transmitter.  If the emergency stop function works correctly, then restart the transmitter. 

3.  Confirm that the movement of the crane or other equipment corresponds to the appropriate 

control being activated on the transmitter. 

 
4.1.3 Checking Battery Power 
The transmitter will not work properly unless sufficient battery power is available.  Before each use, 
check the battery power and, if needed, replace the batteries following the battery changing 
procedure in Section 5.3 (handheld models) or 5.4 (joystick model). 
 
Remaining battery power is indicated by the color of the transmitter’s LED display (the circular light 
adjacent to the green Rotary Key Switch).  When the unit is turned on and whenever any button is 
pressed, the LED will turn green, yellow, or red to indicate the remaining power. 
 
To avoid motion of the crane or other equipment, use the Rotary Key Switch during a manual 
battery check.  To do this, turn the green Rotary Key Switch clockwise past “ON” to the “START” 
position and hold it there.  The LED will indicate the remaining power according to Table 4-1-3 
below (Note:  Ensure that the R0 Relay is not connected to any device because this step will activate 
that relay): 
 
Table 4-1-3  Battery Power Indicator 

Sufficient power to operate. 

Battery power is too low. Change the batteries as soon as it is 
safe to do so. A warning beep will sound every 4 seconds when 
any button is depressed.  Follow the battery changing procedure 
in Chapter 1, Section 5.3 (handheld models) or 5.4 (joystick 
model). 

There is insufficient power to operate normally and the 
transmitter will send an emergency stop signal to the receiver.  
Follow the battery changing procedure in Chapter 1, Section 5.3 
(handheld models) or 5.4 (joystick model).
