BATTERY INFORMATION
INSTALLATION
Open the battery compartment using a coin in the slot in the bottom of the receiver or transmitter.
Press the batteries into place, observing proper battery polarity. Incorrect insertion of the battery is
difficult, and if forced, may cause both mechanical and electrical damage to transmitters or receivers
not covered by the five year warranty. Units will not work with the battery incorrectly installed.
NON-RECHARGEABLE BATTERIES
In normal use, two AA 1.5 V alkaline batteries (BAT 001) will last about 20 hours in the PFM T32
Transmitter or 12 hours in the T31 Transmitter. The batteries will last approximately 100 hours in
the PPA R35 Receiver. If the sound becomes weak or distorted, replace the batteries. Do not leave
dead batteries in the receivers. Battery corrosion is not covered by the Williams Sound five year
warranty.
RECHARGEABLE BATTERIES
The PFM T32 or T31 Transmitter and PPA R35 Receivers can use rechargeable AA batteries
(BAT 026). On an overnight charge, these NiMH batteries are designed to operate a PFM T32
Transmitter for 20 hours or T31 Transmitter for approximately 10 hours, and PPA R35 Receivers for
56 hours.
Note: The battery installed in the receiver may be recharged in the receiver only if it is a NiMH
battery, and only if a Williams Sound CHG 3512 Multi-Charger is used. Damage from improper
charging is not covered by the Williams Sound five year warranty.
Important Rechargeable Battery Information
Rechargeable batteries are shipped in a discharged condition. They must be charged for a complete
charge cycle before the first use. Rechargeable batteries will need to be replaced after 1-2 years of
use. Do not dispose of batteries in fire. Do not open batteries - toxic chemicals inside.
