4.2.1  Entering a Password (Optional) 
The F22 Series Handheld models provide the ability to require a four-character password before use.  
This feature helps prevent unauthorized or inadvertent use of industrial equipment.  This feature 
must be enabled, and the password set, at the factory. 
 
If this option has been enabled, then the operator will be required to enter a four-character password 
before operating the transmitter.  To enter a password, follow the steps below during normal power-
on (Note: Do not follow the steps listed in Section 4.1.2): 
 
1.  Rotate the red EMS Button clockwise 45

° and pull out. 

2.  Turn the green Rotary Key Switch clockwise to the ON position (Note:  Do not turn the switch 

all the way to START). 

3.  While the LED is flashing green, press the pushbuttons sequentially to enter the four-character 

password (Note: There is a 10-second time limit). 

4.  If the password was entered correctly, then the buzzer will sound one long tone. 
5.  After the buzzer stops, turn the Rotary Key Switch to the START position and release. It will 

spring back to the ON position.  The transmitter is now ready for normal use. 

6.  If the password  was entered incorrectly,  then the buzzer will sound two short and one long tone. 
7.  After the buzzer stops, re-enter the correct password. 
 
Table 4-2-1. Signals for Correct / Incorrect Password 

 
Note: The password must be re-entered to return to normal operation if either: 
 
1.  The EMS Button is pressed; OR 
2.  An emergency stop signal is sent to the receiver due to a (factory-settable) period of inactivity 

(see Sections 10.4 and 10.5 for a description of the Auto-Shutdown feature). 

 
4.2.2 Ratcheting Operation 
 
Ratcheting is the ability to increase or decrease speed in discrete steps.  This function is available on 
handheld models F22-10D1, F22-12D, F22-6D and F22-6D1. The “ratchet up” button is 5 on      
F22-10D1 and F22-12D, and South on F22-6D and F22-6D1.  The “ratchet down” button is 6 on 
F22-10D1 and F22-12D, and North on F22-6D and F22-6D1.  To use ratcheting: 
 
1.  Press and hold the button controlling the desired motion, then press the “ratchet up”  

pushbutton to incrementally increase the speed of the equipment, or the “ratchet down” 
pushbutton to incrementally decrease the speed of the equipment. 

2.  When a motion button is fully depressed, one touch of the “ratchet up” button will move to the 

next highest speed.  Repeated touches will increase the speed up to four more times (six total 
speeds, including the initial 2-step button press).
