EXPLICIT DEFINITIONS
WORD
DEFINITION
WARNING
Personal injury,  re hazard or electric
shock may occur.
CAUTION
Equipment damage may occur.
NOTE
If disregarded, inconvenience only.
No risk of personal injury,  re or
electric shock.
PRECAUTION
WARNING HIGH VOLTAGE! NEVER
attach an antenna or internal antenna connector
during transmission. This may result in an
electrical shock or burn.
WARNING HIGH VOLTAGE! NEVER
install the antenna at any place that person can
touch the antenna easily during transmission.
This may result in an electrical shock or burn.
NEVER
apply AC to the [BATTERY] terminals
on the repeater rear panel. This could cause a
 re or damage the repeater.
NEVER
apply more than 16 V DC, such as a
24 V battery, to the [BATTERY] terminals on the
repeater rear panel. This could cause a  re or
damage the repeater.
NEVER
let metal, wire or other objects touch
any internal part or connectors on the rear panel
of the repeater. This may result in an electric
shock.
NEVER
expose the repeater to rain, snow or
any liquids.
AVOID
using or placing the repeater in areas
with temperatures below –30°C (–22°F) or above
+60°C (+140°F). Be aware that temperatures
on a vehicleʼs dashboard can exceed 80°C
(+176°F), resulting in permanent damage to the
repeater if left there for extended periods.
AVOID
placing the repeater in excessively dusty
environments or in direct sunlight.
AVOID
putting anything on top of the repeater.
This will obstruct heat dissipation.
Place the repeater in a secure place to avoid
inadvertent use by children.
BE CAREFUL!
The heatsink will become hot
when operating the repeater continuously for long
periods.
BE CAREFUL!
If a linear ampli er is
connected,  rst set the repeaterʼs RF output
power to less than the linear ampli erʼs maximum
input level, otherwise, the linear ampli er will be
damaged.
Use Icom microphones only (optional). Other
manufacturerʼs microphones have different pin
assignments, and connection to the C
Y-F121S/
CY-F221S
series may damage the repeater.
For U.S.A. only
CAUTION:
This repeater is intended for use
as a  xed base station with the antenna located
outdoors on the rooftop or on antenna tower,
or indoors with the antenna located near the
repeater.

INSTALLATION AND CONNECTIONS
■
Unpacking
After unpacking, immediately report any damage
to the delivering carrier or dealer. Keep the
shipping cartons.
For a description and a diagram of accessory
equipment included with the CY-F121S/221S
series, see ʻSupplied accessoriesʼ of this
manual.
■
Selecting a location
Select a location for the repeater that allows
adequate air circulation, free from extreme
heat, cold, or vibrations, and away from TV
sets, TV antenna elements, radios and other
electromagnetic sources.
■
Antenna connection
For radio communications, the antenna is of
critical importance, along with output power and
sensitivity. Select antenna(s), such as a well-
matched 50 Ω antenna, and feedline. 1.5:1 or
better of Voltage Standing Wave Ratio (VSWR)
is recommended for desired band. Of course, the
transmission line should be a coaxial cable.
CAUTION: Protect repeater from lightning
by using a lightning arrestor.
NOTE: There are many publications
covering proper antennas and their
installation. Check with your local dealer for
more information and recommendations.
■
Duplexer
A duplexer is separately required when only
one antenna is used for both transmitting and
receiving. Select a duplexer according to the
transmitting and receiving frequencies. Ask your
Dealer for details.
■
Grounding
To prevent electrical shock, television interference
(TVI), broadcast interference (BCI) and other
problems, ground the transceiver through the
[GND] terminal on the rear panel.
For best results, connect a heavy gauge wire or
strap to a long earth-sunk copper rod. Make the
distance between the [GND] terminal and ground
as short as possible.
WARNING:
NEVER
connect the
[GND] terminal to a gas or electric pipe,
since the connection could cause an
explosion or electric shock.

Make sure the [POWER] switch is turned OFF
when connecting an AC power cable or a backup
battery (emergency power supply).
The CY-F121S/221S series can operate with an
AC or DC power supply. If AC power is interrupted
when operating the repeater with an AC power
supply, power is automatically provided to the
[BATTERY] terminals.
NOTE:
If turning the repeater OFF using the
rear panel switch, wait a few seconds before
turning it back ON. Otherwise, Logic circuits
may not sense the transition and operate
correctly.

In AC operation
• Use the supplied AC power cable for
connection to a domestic AC outlet.
• Extension cords should not be used unless
absolutely necessary. Using improper
extension cords could result in  re risk.

In DC operation
CAUTION:
Voltages greater than 16 V DC
will damage the repeater. Check the source
voltage before connecting the power cable.
•
DO NOT place the backup battery on or near
the repeater. Lead-acid batteries should be
placed at least 5 m (16.4 ft.) away from the
repeater. Use a heavy duty cable to make
the connection and be sure both the positive
(red) and negative (black) terminals are
correctly connected.
•
When connecting to the battery, connect the
DC power cable to the repeater  rst, then
the positive (red) terminal and negative
(black) terminal to the battery. This is to
prevent electric shock or circuit damage.

Fuse replacement
If a fuse blows or the repeater stops functioning,
try to  nd the source of the problem, and replace
the damaged fuse with a new, rated fuse.
Replace the circuitry fuse as shown below.
WARNING:
DISCONNECT
the AC
power cable and/or DC power cable from
the repeater. Otherwise, there is danger of
electric shock and/or equipment damage.
