FIGURE 1: HOW THE SYSTEM WORKS
Your PFM System has two principal parts: the Transmitter and the
Receiver. Much like a miniature radio station, the Transmitter and
microphone pick up the sounds you want to hear and broadcast
them over an FM radio signal. The receiver and earphone are used
to pick up the broadcast up to 30 meters (98.4 feet) away.

BATTERY INFORMATION
INSTALLATION
Open the battery compartment by lifting the tab on the back of
the transmitter or receiver with your finger. To remove depleted
batteries, pull up on the fabric strip.
IMPORTANT: If Alkaline (non-rechargeable) batteries are
being installed, slide the battery selection switch in the battery
compartment to the “Alkaline” position. See FIG. 7 below. If
installing NiMH (or rechargeable) batteries, slide the battery
selection switch to the “NiMH” position.
Press the batteries into place over the fabric strip. Be sure to
observe proper polarity (+/-). Damage due to improper battery
installation may void the warranty on the product. Close the
battery door. LED will flash when the batteries are getting low;
continue to use until the sound becomes weak or distorted, or
the unit quits operating, then replace or recharge batteries.
FIG.7: BATTERY INSTALLATION
HINTS FOR USING THE SYSTEM
The maximum operating distance between the transmitter and receiv-
er is about 30 meters (98.4 feet). The operating range will vary in dif-
ferent buildings and surroundings. In some locations, the signal may
momentarily disappear. This is called a “drop-out” and is due to
reflection and cancellation of the radio signal. Moving a few feet
should restore the signal.
Keep the transmitter and receiver units at least 1 meter (3.2 feet)
apart. If the transmitter gets too close to a receiver, it may overload
the receiver, causing noisy reception or blocking of the signal.
Do not use more than one transmitter on the same channel (frequen-
cy) at the same time unless they are physically separated by more
than 60 meters (196.8 feet). Operating more than one transmitter on
the same channel at the same time in the same place will result in
interference.
USING MULTIPLE PERSONAL FM SYSTEMS FOR MULTIPLE GROUPS:
For multiple groups using the Personal FM system within the
same facility, multiple Personal FM systems may be operated on
the same channel at the same time by maintaining physical separa-
tion of more than 60 meters (196.8 feet) between groups. The
physical separation of groups takes advantage of the FM capture
effect which causes receivers to lock onto the closest transmitter.

INCASE OFDIFFICULTY
If your Personal FM System is not working, check the following:
1. First, read through this manual carefully to verify proper setup and
installation of your system.
2. Make sure the batteries are fresh or completely charged and that
the “plus” and “minus” terminals are installed correctly.
3. If the rechargeable batteries will only work for a short period of
time (less than 1 hour) even after they are fully charged, they must
be regenerated. Leave them in the receiver or transmitter with the
unit turned on for 5 - 6 hours. Then turn receiver or transmitter off,
place it in the charger, and fully charge the receiver and transmitter
(refer to charger instruction manual). This should restore normal
battery life. Rechargeable batteries will gradually lose their capaci-
ty over time and should be replaced every one to two years.
4. Make sure the microphone is plugged into the T863 transmitter and
the earphone or headphone is plugged into the R863 receiver.
5. Move the transmitter and receiver closer together. You may be out
of range. When using the system indoors, it’snormal for the signal
to momentarily disappear in certain locations. This is called a
“drop-out.” Moving a few feet will restore the signal.
6. Do not try to use more than one transmitter on the same channel in
close proximity to each other. MORE THAN ONE TRANSMITTER
ON THE SAME CHANNEL WILL RESULT IN INTERFERENCE
IF THEYARE CLOSE TOGETHER. Keep the transmitters at least 60
meters (196.8 feet) apart or use separate channels for each system used.
7. If you are still hearing interference on the receivers, turn the transmit-
ter off and listen with a receiver. If you hear the interference with the
transmitter off, you need to change to a clear channel. Call Williams
Sound Customer Service Dept. at 1-800-843-3544 (U.S.A.) or
[phone] (Outside the U.S.A.) for details.
NON-RECHARGEABLE BATTERIES
In normal use, two AA 1.5 V alkaline batteries (BAT 001) will
last about 20 hours in the T863 transmitter. The batteries will
last approximately 40 hours in the R863 receiver. If the sound
becomes weak or distorted, replace the batteries. Do not leave
dead batteries in the receiver. Battery corrosion is not covered
by the Williams Sound warranty.
RECHARGEABLE BATTERIES
The T863 transmitter and R863 receiver can use rechargeable AA
batteries (BAT 026). On an overnight charge, these NiMH batteries
are designed to operate for 15 hours in the T863 transmitter and 30
hours in the R863 receiver.
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 charg-
ing is not covered by the Williams Sound 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.
!! IMPORTANT WARNINGS !!
DO NOT ATTEMPT TO RECHARGE ZINC CARBON
(“HEAVY DUTY”) , ALKALINE, OR LITHIUM BATTERIES!
DO NOT ATTEMPT TO RECHARGE DISPOSABLE BATTERIES!
These batteries may heat up and explode, causing possible injury
and damage to the equipment.
Avoid shorting the plus and minus battery terminals together with
metal objects. Battery damage and burns can result!
