l FEATURES
YourFR-541Family Radio is a portable, easy to use, two-way radio that you can carry
almost anywhere. It is skillfully constructed to give you reliable communications for many
different applications. The FR-541 is ideal for use around the house, in your boat, on
hunting and camping trips, on the ski slopes or at the mall.
m PERFORMANCE
Your transceiver will achieve its maximum operating range when communicating with
other transceivers in a flat open area with no trees or buildings obstructing its signal.
Range may be up to two miles under such conditions. Obstacles such as buildings,
ees or mountains will tend to reduce the transceivers effective range.
:-CCWARNING
Replacement or substitution of transistors, diodes or other parts of a unique nature, with
parts other than those recommended by the manufacturer, may cause a violation of the
technical regulations of Part 15 of FCC Rules.
SAFEI-Y INFORMATION
Your wireless hand-held portable transceiver contains a low power transmitter. When
the PlT button is pushed it sends out radio frequency (RF) signals. The device is
authorized to operate at a duty factor not to exceed 50%. In August 1996, the Federal
Communications Commissions (FCC) adopted RF exposure guidelines with safety
levels for hand-held wireless devices.
Important: To maintain compliance with the FCC s RF exposure guidelines hold the
transmitter at least 2 inch ( 5 centimeters ) from your face and speak in a normal voice,
\ivith the antenna pointed up and away. If you wear the handset on your body while using
the headset accessory, use only the Audiovox supplied belt clip for this product and
ensure that the antenna is at least 2 inch ( 5 centimeters ) from your body when
transmitting. Use only the supplied antenna. Unauthorized antennas, modifications, or
attachments could damage the transmitter and may violate FCC regulations.
Normal Position: Hold the transmitter approximately 2”from your face and speak
in a normal voice, with the antenna pointed up and away.

oower:ng the unit:
{our radio transceiver operates on four AAA batteries. Alkaline batteries will
provide slightly better performance than rechargeable batteries. Only Audiovox
approved rechargeable batteries can be recharged in the radio transceiver using
the optional charger. This will ensure optimum performance for your radio. Use of
the Audiovox charger with other brands of batteries is not recommended as battery
charging times will vary. Refer to the manufacturerer’s instructions for charging
other brands of batteries.
Batteries
There are three methods of powering the unit:
1.Alkaline Batteries.
WARNING: Do not attempt to recharge Alkaline batteries.
2.Audiovox Rechargeable Ni-MH Batteries - (Rechargeable Ni-MH
batteries and Charging Stand not included). Use only Audiovox
approved rechargeable batteries and charger when charging
batteries internal to the unit.
NOTE: To extend battery life, avoid overcharging the batteries.
3. Various Brands of Rechargeable Batteries - Use of the
Audiovox charger with other brands of rechargeable batteries is not
recommended, as battery charging times will vary with different
brands of batteries. Refer to the manufacturers’s instructions for
charging other brands of batteries.
The following guidelines will improve performance and provide longer oper-
ating times for your radio:
Do not mix old and new batteries.
The use of alkaline-type batteries is recommended to provide the longest oper
ating time.
3. Do not mix alkaline, standard (carbon-zinc) or rechargeable batteries.
4. If the unit is not to be used for an extended period of time, remove the
batteries. Old or leaking batteries can cause damage to the unit and will void
the warranty.

n BATTERY INSTALLATION
Your FR-541 requires four AAA alkaline or four re-
chargeable AAA cells. Alkaline batteries will pro-
vide the best performance from your transceiver.
Remove the battery cover by releasing the clip latch
at the top, and sliding the clip up and away from the
back of the unit. Slide the battery cover downward
while applying pressure at the embossed arrow.
Observe the polarity symbols inside the battery tray
when installing the batteries.
CLIP EMBOSSE’;
RELEASE ARROW
Your FR-541 has a unique circuit designed to dramatically extend the life of its
batteries. After 5 seconds of inactivity, the FR-541 will switch to battery saver
mode. While in battery saver mode, the battery saver mode indicator ( x ) is
present on the display, and the transceiver will remain ready to receive’any in-
coming transmissions while the battery saver mode is active. Pressing any of
the buttons, except the up, down, Function (F) or VOX button will exit the battery
saver mode.
