BATTERY INFORMATION

INSTALLATION

To open the T31 transmitter battery compartment, use a coin in the slot on the bottom of the

transmitter. To open the R35 receiver battery compartment, lift the tab on the back of the receiver

with a finger. 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 (BAT001) will last about 12 hours in the

PFM T31 Transmitter and approximately 100 hours in the PPAR35 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 T31 Transmitter and PPAR35 Receivers can use rechargeable AA batteries

(BAT 026). On an overnight charge, these NiMH batteries are designed to operate a PFM T31

Transmitter for approximately 10 hours, and PPA R35 Receivers for 56 hours.

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 (approximately 4 hours). 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.
