Receiver Model WIR RX4
The RX4 is a headset-style receiver. Make sure the
“eye” on top of the receiver is not covered up when
in use.
Step 1:
Battery Installation: Open the battery
compartment by sliding the battery door
open on the earpiece. Press two AAA
batteries into place, observing proper
battery polarity. Slide the battery door
closed, taking care not to crush the plastic
locking tabs.
Step 2:
Turn the power switch on top of the
receiver on. Adjust the volume control
wheel located on the bottom of the
headset.
Battery Information for Receivers
For the RX3 Receiver in normal use, a heavy-duty 9
Volt battery such as the Eveready 216 will last about
10 hours. Alkaline batteries such as the Eveready
522 will provide about 17 hours of use. For the RX4,
alkaline AAA batteries will last about 20 hours. If
the sound becomes weak or distorted, replace the
battery. The indicator light may still be on, even
with a battery that is weak. Do not leave dead
batteries in the receivers, they may leak and damage
the receiver.
Rechargeable Batteries:
The RX3 receivers can also use a rechargeable
battery. We recommend only the 7-cell, 8.4 Volt
types
(BAT 003). A fully-charged battery (Williams BAT
003) will provide about 5 hours of use per charge.
The battery may be recharged without removing it
from the receiver.
The BAT 005 Single Charger has a cord that plugs
into the receiver “EAR” jack to charge the battery.
The CHG 1269 Multiple Charger can charge 12
receivers simultaneously through the receiver “EAR”
jacks.
The receiver should always be turned OFF while
charging. It takes about 14 hours to fully charge the
battery. If the battery is providing very short service
life (under 1 hour of use) let it drain completely by
leaving the receiver on for several hours and then
immediately recharge it.
Receivers can be left charging continuously when
not in use.
DO NOT ATTEMPT TO RECHARGE DISPOSABLE
BATTERIES!
AVOID SHORTING PLUS AND MINUS BATTERY
TERMINALS TOGETHER WITH METAL OBJECTS.
BATTERY DAMAGE AND BURNS CAN RESULT!
DO NOT MIX RECHARGEABLE BATTERIES &
CHARGERS FROM DIFFERENT
MANUFACTURERS.
