Keys
Some keys on the handsets have more than one function,
depending on what mode the radio is in. For example, [OK] for
accepting input and [H/L] for selecting high or low transmission
power are activated using the same key. To activate the lower
function on the key label, press and hold the key until the radio
responds.
A complete reference to keys is given in “Appendix 2 - Keys
reference” on page 97.
Soft keys
A soft key is a name that appears at the bottom of the screen and
provides additional functionality to the [SCAN] and/or [OK] and/or
[3CH] buttons during DSC operations.
Dot symbols on the handset keys and just under the display screen
indicate which keys correspond to the soft keys as follows:
• • • • • •
[SCAN] key [OK] key [3CH] key
The use of these keys is explained in the DSC section of this manual.
