Cover Ports When Not in Use
Whenever a port is not in use, make sure the port is covered. This keeps the contacts clean and
prevents inadvertent short-circuiting. Finger-tighten the covers, but do not use tools.
To reduce the risk of ignition of hazardous atmospheres, recharge, remove, or replace
the battery only in an area known to be non-hazardous! Recharging the battery pack can
be performed in hazardous area only via IS charge port.
When power is applied and the BW RigRat battery is charging. When the battery is fully
charged, the Full Charge icon is shown accompanied by "100%." If the instrument is off
but is being charged, it shows the charge state and percentage.
