2.1 Using the 6541
The 6541 is simple to install and use. At installation all adjustments are made using
the switches located inside the front cover. Each instrument has a LCD display that
shows the water level reading and updates automatically as the water level changes.
The instrument is powered by an internal pack of alkaline batteries with a service
life of more than 12 months. The LCD will flash “Lo Batt.” when the battery pack
nears full discharge and requires replacement.
