The “##” under the “POWER DOWN INTERVAL” menu is equal to a number from 0 to 99 hours. Entering
“0” hours disables the “POWER DOWN INTERVAL” feature. When the remaining “POWER DOWN
INTERVAL” time period falls to five minutes or less, an icon (resembling a small clock) will appear at the
lower right hand side of the display in place of the time of day. After two-seconds, the icon will then
disappear and the time of day will reappear in its place. The icon and the time of day will then alternate
appearances, at two-second intervals, until either the “POWER DOWN INTERVAL” has expired (as
evidenced by the unit turning off), or the “ESC” key is pressed, which will then add one hour to the
“POWER DOWN INTERVAL.” Also, an audible “beep” will be present, at one-minute intervals, until the
“POWER DOWN INTERVAL” has expired or the “ESC” key has been pressed. This will also occur when
the “POWER DOWN INTERVAL” time period falls to five minutes or less.
Response Time Adjustment
Response Time adjustment contains seven settings/selections: 1, 2, 4, 8, 16, 32 and “AUTO” seconds
(see Figure 2-18). When “AUTO” seconds is selected, the response time will automatically vary between
one (1) second and 32 seconds, depending on the intensity of the field that is currently being measured
(i.e. higher-intensity radiation fields will shorten the response time; lower-intensity fields will lengthen it
accordingly). Pressing the “SEL” key saves the setting and returns to the normal operating screen.

Log Data Set-up
The “LOG DATA SETUP SUB-MENU,” when selected from the “MODES SUB MENU,” consists of five
items: “MANUAL,” “MANUAL WITH BARCODE,” “TIMED,” “SURVEY,” and “SURVEY W/BARCODE”
(See Figure 2-19).
If the user selects “MANUAL,” data can be logged by pressing the “START/STOP/RST/SAVE” key. The
message “SAVE DATA? YES NO” is then displayed.
