Rechargeable Batteries
The R-3 uses a Nickel-Metal-Hydride battery
pack stored in the battery compartment.
Leaving the AC adaptor connected to the R-
3 and plugged into an AC line, even when
not in use, ensures the batteries will be fully
charged when you need to use the R-3 on
battery power. The R-3 can be used for 3 to
3.5 hours after batteries are fully charged.
(When the volume is set to 20.)
<
When the batteries need to be recharged,
the STANDBY/ON indicator blinks at
regular intervals. The blinking interval will
grow faster as the batteries get closer to
discharge until the R-3 shuts off
automatically to protect the batteries.
<
When the R-3 is not being used but the
AC adaptor is plugged in, the batteries
will be completely charged within
approximately 3.5 hours from a full
discharge. During this period the
STANDBY/ON indicator will flash.
<
When the R-3 is ON and the AC adaptor
plugged in, the batteries will be
completely charged within approximately
24 hours.
<
It may take up to 4 charge and discharge
cycles before the batteries are operating
at full capacity when the R-3 is new or
left unused for several weeks.
It is suggested that the R-3 be plugged in
for about 12 hours before you use it for
the first time.
<
Once the R-3 has been fully charged
while it is STANDBY, do not unplug the
AC adaptor and then immediately plug it
again. This will restart the charging cycle
even though the batteries are fully
charged. Doing this repeatedly will
damage the batteries.
<
If the R-3 is not plugged in, the batteries
will slowly discharge as a safety measure.
Battery Replacement
When the batteries are exhausted, replace
the battery pack with a new one.
1. Remove the battery compartment cover.
2. Disconnect the battery pack connector,
and remove it.
3. Insert a new battery pack and attach its
connector.
4. Close the cover.
Caution:
<
Do not heat or disassemble rechargeable
batteries. Never dispose of old batteries
by throwing them in a fire
