6-1.Instrument Switch
1.Long press the Button for about 3 seconds to start the instrument; Long press the on button again forSwitch
about 3 seconds to shut down the instrument.
2.When the instrument is on, the LCD backlight will automatically reduce the brightness after no operation for one
minute.
3.Press any button again to turn on the LCD backlight again without automatic shutdown function.
6-2.Instrument Switching Unit
1.Press the Button to switch between µSv/h and µR/h, not only the current measured value, but also theUnit
cumulative value and the maximum value (Save the current last display unit each time you shut down).
2.Unit switching formula: 1µSv/h=100µR/h

6-3.Instrument Menu Setting
Short press the Button to enter the menu setting mode, you can set pulse and key sound switch, 24 hours andSet
12 hours switch, time, alarm threshold of measured value, alarm threshold of cumulative value.
• Pulse and Button sound: ON and OFF two state options
• 24 hours switch: 24 hours and 12 hours can be selected
• Time format: hour: minute
• Measurement Alarm threshold: 0.00-9999µSv/h, the default is 0.5µSv/h
• Cumulative alarm threshold: 0.000-99.99µSv/h, the default value is 3.0µSv/h
6-3-1.Set Pulse and Button Sound Switch
1.Press the Button once, then “ ” will flash, LCD will display “ ” or “ ”, through “ ” or “ ” changeSet ON OFF
the value, then press the Button to confirm saving and enter the 24-hour setting mode, or long press theMenu
Set Button to exit the setting mode directly.
2. When the acoustic switch is on, the meter will emit adrop” sound after detecting radiation rays, the stronger
the radiation signal is, the faster the sound frequency will be.
6-3-2.Set the Switch Between 24 Hour System and 12 Hour System
1.Press the Set Menu 12H 24H Button once, switch mode through “ ”, switch to LCD display “ ” or “ ”, through “ ”
or “ ” change the value.
2.Then press the Button to confirm saving and enter the time setting mode, or long press the Button toMenu Set
exit the setting mode directly.
6-3-3.Set Time
1. Press the Button once, switch mode through ”, switch to the hour of time for flashing, through “ ”Set Menu
or “ ” change the value, then press the Button to confirm saving and enter the minute setting mode, orMenu
long press the Button to exit the setting mode directly.Set
2. Press the Button once, switch mode through “ ”, switch to the time minute flash, through “ ” or “ ”Set Menu
change the value, then press the Button to confirm saving and enter the alarm threshold setting mode, orMenu
long press the Button to exit the setting mode directly.Set
6-3-4.Set the Alarm Threshold of the Measured Value
1.Press the Button once to switch mode through the “ ”, at this time, the LCD only flashes the value ofSet Menu
measurement display.
2.Through “ ” or “ ” change the value, press the Button to confirm saving and enter the cumulativeMenu
threshold setting mode, or long press the Button to exit the setting mode directly.Set
6-3-5.Example Set the Cumulative Threshold
1. Press the Button once to switch modes through the “ , at this time the LCD only flashes the ones bitSet Menu
of the accumulated value, changing the value by “ ” or “ ”.
• Press the Button for the first time to set the cumulative value threshold to one decimal place;Menu
• Press the Button a second time to set the cumulative value threshold to two decimal places;Menu
• Press the Button a third time to set the cumulative value threshold to three decimal places.Menu
• Press the Button a fourth time to save the threshold and exit setting mode.Menu
2.When the cumulative value threshold exceeds 10, the cumulative value threshold can only be set to two decimal
places, then press the Button for the third time to exit the setting mode.Menu
3.Hold down the Button to exit the setting mode.Set
7.Alarm Type
1.Alarm of exceeding the measured value threshold: If the current measured value exceeds the set measured value
threshold, the instrument will make a long alarm.
2.Alarm of exceeding the accumulated value threshold: If the current accumulated value exceeds the set accumulated
value threshold, the instrument will sound two alarms within one second.
3.When the battery of the instrument blinks in the space, the instrument will emit a short and rapid alarm sound,
at this time, you can press any button to stop the current low power alarm.
8.Range Display Type
9.Battery Charge
• The Detector has built-in batteries, so you do not need to replace the batteries.
• When the battery level symbol blinks, it indicates that the battery is low, use a 5V/1A adapter to charge the battery.
• Please remove the battery before long storage or transportation to prevent battery leakage.
10.Maintain
• Meters should be cleaned with damp cloth and non-irritating cleaner when necessary.
• Do not use corrosive or irritating cleaners.
• Please keep the instrument in the allowed temperature and humidity environment for use and storage.

11. Disposal
For the disposal of batteries in the EU, the /66/2006 EC directive of the European Parliament
applies. Due to the contained pollutants, batteries must not be disposed of as household waste.
They must be given to collection points designed for that purpose.
In order to comply with the EU directive 2012/19/EU we take our devices back. We either re-use
them or give them to a recycling company which disposes of the devices in line with law.
For countries outside the EU, batteries and devices should be disposed of in accordance with
your local waste regulations.
If you have any questions, please contact PCE Instruments.
