4-4 53SL ES Series Mobile Radio Operating Manual April 2009
Basic Operation Section 4 - General Operation
4.1.2.4 Password Entry Procedure
When a password is requested, it is entered as follows:
• Rotate and press the Select switch. A single beep sounds when the switch is pressed (if
that option is selected)
4.1.2.5 User (Power-On) Passwords
Separate Download (write) and Upload (read) passwords can be programmed to prevent
unauthorized downloading or uploading of radio programming parameters. When one or
both of these passwords are used, the proper password must be entered to perform the
operation. A “User” password is not required to upload or download parameters.
4.1.2.6 Master Password
The Master Password overrides all the preceding passwords. It can be used by a system
administrator as a “pass key” to a password controlled function or to change a lost or
inadvertently changed password. Master passwords are set up and changed the same as the
other passwords. It does not override the following Zone Password.
4.1.2.7 Zone Password
A zone password can be programmed with the 53SL ES radio. It prevents unauthorized
reprogramming of zones by keypad programming.
Note The programming and usage of this password has not changed. It is independent from the
preceding passwords, and programmed using PC Configure.
4.1.3 Speaking into the Microphone
For best results, hold the microphone about 1-2 inches from your mouth and speak at a
normal conversational level. Do not shout since it distorts your voice and does not increase
range.
Note
If excessive background noise consistently interferes with communications, Microphone
Sensitivity should be adjusted (using PC Configure).
Make sure that the PTT (push-to-talk) switch is pressed before you begin to speak and
released as soon as the message is complete.
