Understanding the Display Icons
Your PSR-310 features a high contrast, white 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. Figure 4 provides an example of the
display that is shown while the radio is scanning.

Figure 4 - Scanning Display
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.
BAR Signal meter indicating strength of the received signal.
BATT Battery status indicator. Comes on solid when battery is weak, and flashes two times each second
when battery failure is imminent. Briefly flashes approximately once every second when the radio is
connected to external power and the internal battery charger circuit is active.
NOTE: The “internal battery charger circuit active” indicator provides an indication that the 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.
^ v Menu position and search direction indicators.
