Problem
• When charging BP 4000, a rec-
ommended RECOVERY cycle
was not run. Remaining battery
life is not indicated.
• Volume too high and battery
voltage too low. SPR 4 limiter is
automatically activated to avoid
premature power-down.
• Battery/BP 4000 capacity lower
than 20%.

low for a moment (dropout).

10 seconds, warning comes up
again.
• Internal error.
Remedy
• Press Jog switch briefly and run
RECOVERY cycle next time you
charge BP 4000.
• Press Jog switch briefly to reset
limiter to last active mode. Re-
duce volume or replace batter-
ies/charge battery pack.
• Replace batteries/
charge BP 4000.
1. Press Jog switch briefly. (Warn-
ing disappears.)
2. Relocate transmitter/antenna. If

soon as possible, even if prob-
lem appears to be corrected.
