Hardware setup
There are four buttons on the front of the unit: S1, S2, S3 and S4 (from left to right)
1. Power up the unit. Pressing the S4 (power) key for 3 seconds will turn on the unit.
Check the battery level. Charge the battery fully when first time use.
It may take a few hours to get the battery fully charged. Check the battery icon on the display,
a fully charged battery icon will be filled with solid color, without flashing.
2. Set date/time. Press the S4 key to enter the menu and set the date and time. This is very
important for time stamping the recorded data. Do not skip this step. Most of the data are
related to the date and time.
3. Set the backlight timeout in second, in order to minimize the power consumption.
Set the power savings mode. If the power savings mode is ON, then the LCD display will be
turned off after 30 second if no key is being pressed during this period.
4. Now the unit is ready to use. You should see the background CPM rate in absence of a
radioactive source.
Note: There is a transparent protective sheet covering the units surface. Users need to remove it to
get better view of the LCD display.
