turns the speaker completely off. The unit will not sound
a tone when a key is pressed, nor will any alarm sound.
The alarm messages will still flash on the screen, how-

Contrast

To adjust the display's contrast, highlight the "Contrast"
label. Press the right or left arrow keys until the screen's
contrast is best for the lighting conditions.

To turn them off, press the PWR key again. A light bulb indicator on the
satellite status screen shows when the lights are on.

The lights automatically turn off after 30 seconds to
preserve the battery power. It will do this even if the
external power is applied to the unit. The time delay is
adjustable from 5 to 240 seconds by selecting Light
Dly from the System Setup menu . You can also turn
the lights on continuously from this menu. Highlight this
menu, then press the right arrow key to increase the
time the lights are on, the left arrow key to decrease it.

Set Local Time

When this unit is first initialized, it may not show the
correct time for your location due to daylight savings time, time zone vari-
ances, and so on. If the time shown on the clock displays is incorrect,
select "SET LOCAL TIME" from the system setup menu and press the
right arrow key. The screen shown at the top of the next page appears.
