2.10 Switching Key Lock
You can disable the keys on the Polaris MINI to prevent the accidental pressing
of keys using the key "Lock" switch on the front panel.
When the key "Lock" switch is placed in the left-most position, Polaris MINI
announces, "all keys locked". This means all keys on the unit are disabled
including the on/off switch. If the key "Lock" switch is placed in the center position,
Polaris MINI says, "top panel locked". This means you can continue to use the
buttons and switches on the front panel (media mode switch, media buttons and
on/off switch), however, you cannot use any of the keys on the top face of the
unit. If the key "Lock" switch is placed in the right-most position, Polaris MINI
announces, "unlocked". This indicates all keys are operational.
To lock and unlock only the keys on the front media panel, press the "Back" and
"Forward" media buttons simultaneously. The unit announces "Media keys
locked". If you press the keys again, the unit announces "Media keys unlocked",
and the media buttons are again operational.
