Light-emitting diode
The green light-emitting
diode located in the top
cover of the unit has two
funtions:
1: ON/OFF indicator.
2: Battery indicator.
The unit will turn itself on and
the diode will light up when
a signal is received from the
stethoscope. If no signal is
received, the unit will turn
itself off after one minute.
A blinking diode indicates that
the batteries are weak.
No light indicates that there is
no signal or that the batteries
are completely drained.
Batteries
[thedistributor) runs on
two easily replacable high-
energy TL-5902 lithium

1/2 AA, ER14252.
The batteries are estimated
to provide an effective
listening time of 200 hours.
Change batteries by pushing
the cover back. Check that
the batteries are installed
