
Do not touch the battery poles or contacts of the RF devices with bare fingers! A layer of
grease causes transfer resistance to build up between the batteries and contacts. This
transfer resistance may lead to the FACP prematurely or incorrectly displaying low battery
voltage (batt. < 30).

Improper storage of the RF devices and batteries may be the cause of such transfer
resistance (e.g. due to corrosion). If necessary, clean contacts before inserting the
batteries (e.g. with isopropanol solution).

Use approved batteries only (Part No. 805597) and change the entire battery set (4 items)
in order to ensure an equal charge. The registered low battery voltage (batt. < 30) on the
FACP always relates to the battery with the smallest capacity.

For RF devices which register low battery voltage after a long operating time, the
malfunction may be repaired during inspection by agitating the batteries used for a short
amount of time (a few hours). When the RF device is activated, no "low battery voltage"
message appears. Always completely replace the set of batteries for the corresponding RF
device!
