4 Setup
Security
To avoid unauthorized use of the instrument, you can activate a PIN / PUK security code.
PIN code
The PIN code is a four-digit code where each digit can be set to a number between 0–9, for example,
1234. If an incorrect PIN code is entered more than ten times, the instrument is locked and the PUK
code must be entered, see PUK code, page 58.
By default, the PIN code is set to 0000. With this code set, security is not activated and the user is not
prompted to enter the PIN code at start up.
The user can activate or change the PIN code (see following topic).
Activating or changing the PIN code
On the Face 2 display, press N or Oto scroll up or down until you see Set PIN and then press P.
Press N or O to enter the PIN of your choice digit by digit—press P to accept each digit.
After all digits have been set, press P to record the pin.
The menu returns to Set PIN.
Using the PIN code to unlock the instrument
When the PIN code has been activated, you must enter it when you start up the Instrument. To do this:
Switch on the FOCUS 35 instrument. The Face 2 display shows the menu Enter PIN.
Press N or Oto enter the PIN of your choice digit by digit—press P to accept each digit.
Once all valid digits have been entered, press P. This unlocks the instrument—the Face 2 display now
shows the menu Instrument Status, the Radio Channel, and the Network ID.
If an incorrect PIN code is entered more than ten times, the instrument is locked and the PUK code must
be entered, see PUK code. When the correct PUK code is entered, the PIN code is reset to 0000 and the
security PIN code is deactivated.
