The Liquid Crystal Display (LCD) in the TLA 852 shows two lines of characters. The
FLA 872 shows four lines of characters (or two lines of double height characters) . Each
line can have a maximum of 20 characters. Both units can also show a maximum of
seven symbols in a line. Lamps (Electro-luminescent (EL) option also available - FLA
Series only) are incorporated in the unit, to illuminate the display when required.

2.2 OPERATING INSTRUCTIONS
2.2.1 General
The operation of most functions of the TLA 852 and the FLA 872 is identical. Where
differences occur, both operations are described.
2.2.2 Switching the Unit ON
When the battery is installed in the unit, the display shows the time and date on the
bottom line and the status symbols on the top line. The display stays on until the
battery is removed or the ‘OFF’ mode is selected.
If the unit is in the ‘OFF’ mode, push and hold the O> button until the Audio and
Vibrate Alerts operate. The display then shows a message for a short time before
the time and date show. This is the ‘standby’ screen.
