3.2.4 Key Lock Function
The <SHIFT>, <ALT>, <CTRL>, <ORANGE> and <BLUE> keys have a lock
function that allows the function of these keys to be locked “on” until you unlock or
turn them “off”.
3.2.4.1 The 7035 Hand-Held Key Lock Function
Refer to “One-Shot Mode” on page 121 to learn how to define the lock and unlock
behaviour of the 7035 modifier keys.
On 7035 hand-held terminals, an onscreen message is displayed in uppercase letters
in the status area at the bottom of the terminal screen to indicate that a key is locked
“on”. For example, when the <CTRL> key is locked “on”, the onscreen message –
CTRL – is displayed in uppercase letters in the status area. For more information
about status area indicators, refer to “Onscreen Indicators – 7035 Only” on page 29.
3.2.4.2 8255 & 8260 Key Lock Function
Keep in mind that vehicle-mount terminals are available in two keyboard types –
‘F1 to F6’ and ‘F1 to ‘F10’ (see “8255 And 8260 Vehicle-Mount Terminal
Keyboards” on page 47 for a brief description). Depending on which keyboard type
you are using, locking and unlocking the <CTRL>, <ALT> or <SHIFT> key differs
slightly. These differences are highlighted in this section.
Important: Make certain that the appropriate keyboard type – ‘F1 to F6’
or
‘F1 to ‘F10’ – is selected in the “Keyboard Type” parameter
(see “Keyboard Type – Vehicle-Mounts Only” on page 130).
On 8255 and 8260 vehicle-mount terminals, LEDs are used to indicate the status of
a key. When a key is locked “on”, the corresponding LED stays on until the key is
unlocked. If you’ve only pressed a key once, the corresponding LED blinks until the
key is no longer active.
Locking And Unlocking The <ORANGE> Key
To lock this key “on”:
• Press the <ORANGE> key once.
To unlock or turn “off” this key:
• Press the locked <ORANGE> key a second time.
Note: The default key lock function of the <ORANGE> key can be changed
using the “One-Shot Mode” parameter (see page 121).
