Understanding the Display Icons
Your ADV0801 features a high contrast, backlit Liquid Crystal Display (LCD) to provide
important information about the status of the radio while you are programming and using it.
The LCD includes a row of icons at the top that provides information about the status of the
scanner while it is operating. Beneath this row of icons, there are 4 rows of 16 characters each
that provide alphanumeric information for frequencies, object names, Scan List status and
menu information.
The top row of icons are defined as follows:
F The Function Key (FUNC) has been pressed. FUNC acts as a "shift" key and typically
enhances in some way the action of the button that follows it. When using FUNC, press the
FUNC key first and release it, then press the next key.
T The scanner is currently receiving trunking control channel data.
G The attenuator is set for Global mode.
A The attenuator is currently active.
S The radio's squelch circuit is open.

battery charger circuit is active, and does not provide positive indication that the batteries are
actually being charged. Batteries will not charge unless the yellow battery holder is used.
