5.0 SWITCH FUNCTIONS AND DISPLAYS

All operations on the MINI-SA Portable Detector are controlled by two push- buttons located on the bottom of the unit. The operations vary depending on the operating mode and the graphic display appearing above the two switches. The unit sounds a brief audible “beep” whenever either pushbutton is de- pressed while the instrument is on. Whenever the instrument is turned ON or OFF, three successive audible tones will sound and the Red Alarm LED will flash. The Green Status LED will flash once every fifteen (15) seconds during instrument operation. When in the BATTERY SAVER mode, the Green Sta- tus LED flash rate increases to once every five (5) seconds.

When the unit is in the operating mode, depressing the Display Backlight Pushbutton will illuminate the graphic display for fifteen (15) seconds. A light bulb icon for the Backlight is located above the pushbutton on the operat- ing mode screen. Depressing the button again extinguishes the Backlight. The Backlight is sustained ON or OFF while the MENU operations are in progress, except for calibration. In an alarm condition, the Backlight flashes for the duration of the alarm indication.

When in the BATTERY SAVER mode, the instrument graphic display will be blank. Depressing either pushbutton will turn on the graphic display. The display remains on for thirty (30) seconds after the last pushbutton opera- tion.

WARNING

USE OF THE DISPLAY BACKLIGHT FOR EXTENDED PERIODS OF TIME WILL REDUCE BATTERY SERVICE LIFE.
