BATTERY INFORMATION
INSTALLATION
Open the battery compartment using a coin in the slot in the bottom of the transmitter. Press
the batteries into place, observing proper polarity. (See Figure 8.)
Incorrect insertion of the battery is difficult, and may cause both mechanical and electrical
damage not covered by the 5 year warranty to transmitters or receivers. Units will not work
with the battery incorrectly installed.
DISPOSABLE BATTERIES
In normal use, two AA 1.5 V alkaline batteries will last about 12 hours in the T31 Transmitter
and approximately 80 hours in the optional R31 and R32 Receivers, respectively.
If the sound becomes weak or distorted, replace the batteries. The indicator light may still be
on, even with batteries that are weak. Do not leave dead batteries in the receivers. Battery
corrosion is not covered by the
Williams Sound five year warranty.
RECHARGEABLE BATTERIES
The
T31
T
ransmitter and optional R31 and R32 Receivers can use rechargeable AA batteries
(BAT 026). On an overnight charge, these Ni-Cad batteries are designed to operate a T31
T
ransmitter for about 10 hours, R31 and R32 Receivers about 50 and 60 hours, respectively.
The battery installed in the receiver may be recharged in the receiver
only if it is a Nickel
Cadmium battery, and
only if the Williams Sound CHG 200A charger is used. Damage from
improper charging is not covered by the Williams Sound five year warranty. For charging
directions, see figure 9,
Using The CHG 200A Battery Charger To Charge Transmitters and
Personal Receivers.
