Hardware Setup; Software Set Up (Optional) - GQ Electronics GMC-SE User Manual

Hardware setup

There are four buttons on the front of the unit: Key1, Key2, Key3 and Key4 (from left
to right)
1. Power up the unit. Pressing the Key4 (power) key for 3 seconds will turn on the unit.
Check the battery level.
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 Key4 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 recorded 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 unit's surface. Users may need to
remove it to get better view of the LCD display.
