Checking battery status
When the BA is pressurised (active mode) the battery status can be checked by
toggling from the primary screen to the secondary screen using either of the green
RESET buttons.
When the BA is not in use (sleep mode) the battery status can be checked on the
control module LCD screen by pressing and holding either of the green RESET buttons
for five seconds to view the battery level status.
Do not check the battery status via the charging cradle. Placing a battery
on a charging cradle will start another charge cycle, which will limit the life
of the battery.
Table 1 summarises the battery charge status and icons.
