Make sure the AC [POWER] switch is turned
OFF when connecting an AC power cable or a
backup battery (emergency power supply).
The CY FR series can operate with either an AC
or DC input. If AC power is interrupted and there
is an external DC source (emergency power
supply), the Repeater will continue to operate
until the DC source is exhausted.
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. The
AC Power switch does not effect the DC
supply. If Repeater is operating on DC, you
must use the power switch(s) on the Radio.
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 fire risk.
• An International AC power cable is available.
The internal AC power supply is jumper
selectable between 120V
ac
and 220V
ac
.
In DC operation
CAUTION:
Voltages greater than 16 VDC
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 first, then
the positive (red) terminal and negative
(black) terminal to the battery. This is to
prevent an electric shock or circuit damage.
