6 SV 104IS MAINTENANCE
6.1 General recommendations for use
If not using the dosimeter it is best to keep the dosimeter in a powered up SA 104-5 or
SA 104-1 docking station. Use docking station charger only on fireproof surfaces;
Charge the SV 104IS instrument in an docking station before attempting to turn it on if the
dosimeter has not been used for a prolonged period or was stored in a low battery state
condition.
It is not recommended to leave the instrument nor accessories in direct sunlight conditions for
prolonged periods of time. Doing so may cause the battery contained inside to generate heat,
explode, or ignite. Using the instrument in this manner may also result in a loss of
performance and a shortened life expectancy.
To improve accuracy of remaining battery life indicator, run the dosimeter until it is fully
discharged; then proceed with a full charge with use of the SA 104-5 or SA 104-1 docking
station. The procedure is recommended before first use. Repeat this procedure year of use
to maintain more accurate current battery condition indication.
Do not disassemble or modify the instrument. The battery inside contains safety and
protective devices, which, if damaged, may cause the battery to generate heat, explode
or ignite.
6.2 Cleaning
Few things to remember:
Every time the SV 104IS gets too dirty, clean the surface of the dosimeter with water damp
soft cloth. Under no circumstances should this equipment be cleaned using a solvent based
cleaner (it can affect the case polymeric materials).
Pay special attention that the provided SA 122IS windshield is clean because dirtiness can
affect the measurements. Take off the windshield, shake off any dirt, and clean it with damp
cloth. If necessary change the windshield to new one. The foam windshield is considered
a consumable item and will need replacing if it becomes lost or its condition deteriorates too
much. Packs of 3 replacement windshields are available under the part number SA 122IS_3.
Pay special attention that the SV 27IS microphone front part is clean because dirtiness can
affect the measurements. Avoid the small inlet hole getting too dirty. Clean carefully with a dry
and soft non-fraying cloth.
