Figure 13. Low battery indicated on display.
When a red LED flashes on the side of the dosimeter, or when a battery symbol is present on the display, the battery
needs to be replaced. You need a Phillips screwdriver (PH1) and a battery (CR2450) for this.
NOTE:
Make sure that the dosimeter is not connected to a computer with a USB cable while replacing the
battery.
1. Remove the screws on both sides of the dosimeter clip.
2. Remove the battery cover.
3. Take out the battery by carefully bending with for example the plastic clip under the battery at the top side of the
dosimeter.
4. Wait at least 5 seconds before inserting the new battery, to make sure that the dosimeter registers that a new
battery is inserted.
5. Put on the cover and the clip (optional) and insert the screws carefully (max 0.15 Nm torque), to avoid damage on
the screw threads.
6. Connect the dosimeter to a computer with Dose View and synchronize the time. The internal clock is the only
thing that is affected by a battery change. Other information in the dosimeter such as name, dose history and
calibration are unaffected.
Check that the dosimeter appears on a display again.
