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.

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.
