Power-Up Password; Programming Passwords; Lost Passwords; Changing Passwords - E.F. Johnson Company 53SL ES Series Operating Manual

Basic Operation
4.1.2
The power-up password feature prevents unauthorized use of the radio by requiring that an
eight-digit password be entered to make it operational. This feature is enabled or disabled
by programming. When a User Password is enabled, it must be entered each time radio
power is turned on.
When it is enabled, "ENTER PSWD" is briefly displayed when power is turned on, the
eight-digit numeric password must be entered by pressing and rotating the Select switch.
A single beep sounds when the switch is pressed (if that option is enabled). If an incorrect
password is entered, "INCORRECT" is displayed and it must be re-entered.
Up to four different User Passwords (User 1/User 2/User 3/User 4) can be programmed.
Currently, the same radio features are enabled for each. Entering any User Password at
power up enables normal radio operation.
The current User password can be changed if the "PW CHG" option switch is
programmed. Selecting this function displays prompts for entering and confirming a new
password.
4.1.2.1
Passwords are programmed using PC Configure. The applicable radio must be connected
to the computer and powered up to display this screen.
Note
Any password changes made to the radio will be immediately applicable when Password
Management is exited.
4.1.2.2
If a password is lost, contact customer service.
4.1.2.3
An assigned password can be changed by the user if the PW CHG option switch is
programmed. Selecting this function displays prompts for entering and confirming a new
password.
Note With the 53SL ES Handheld Control Unit, it is recommended that a number key not be
used for this function because the password mode is exited if that key is pressed to enter a
number.
