4.3 Charging the battery wirelessly (PED+ and PED-ER+)
The PED+ and PED-ER+ can be charged wirelessly using a Qi compatible wireless charger. To charge
wirelessly, the clip must be removed from the PED and the rear surface of the PED placed in contact with
the charging surface. When placed on a wireless charger, the PED may take a few seconds to recognise
the charger after which the charging cycle will begin. Charging progresses in the same way as wired
charging.
Attention : Depending on the charger used, wireless charging may take longer for a full charge cycle than wired
charging. Due to the technology used, when charging wirelessly the PED may become warm. PEDs should always
be charged in a cool environment (no greater than 35°C or 95°F) and out of direct sunlight.
4.4 Cleaning
Clean the mould using a non-abrasive cloth, water, and a mild detergent. The soft polymer over mould that has been
manufactured from materials with excellent chemical resistance and the screen is manufactured from a tough
polymer.
Caution
The screen of the PED-IS has an antistatic coating to prevent the build-up of a static charge. Care
must be taken when cleaning so that the antistatic coating is not removed.
To avoid damaging the antistatic coating the screen must only be cleaned using a non-abrasive cloth, water and a
mild detergent.
The image below shows a PED-IS where anti-static coating has been remove by cleaning incorrectly. By viewing the
PED-IS from different angles, areas of the screen where the antistatic has been removed are easily visible.
4.5 Calibration
Ionising radiation legislation recommends that all operational radiation measurement devices are subjected to regular
inspection and testing. This recommendation includes performance checks and where appropriate, recalibration of
PEDs.
