Installation of Accessories
Antenna Installation
The supplied antenna provides good results over the entire frequency range
of the transceiver. However, for enhanced reception on certain non-Amateur
frequencies, you may wish to connect an an-
tenna designed specifically for that frequency
range, as the supplied antenna is necessarily
a compromise outside the Amateur bands,
and cannot be expected to provide high per-
formance at all frequencies.
To install the supplied antenna, hold the bot-
tom end of the antenna, then screw it onto the
mating connector on the transceiver until it is
snug. Do not over-tighten by using of extreme
force.
• Never transmit without having an antenna connected.
• When installing the supplied antenna, never hold the upper
part of the antenna while screwing it onto the mating con-
nector on the transceiver.
• If using an external antenna for transmission, ensure that the
SWR presented to the transceiver is 1.5:1 or lower, to avoid
excessive feedline loss.
Preparation of SBR-25LI Battery Pack
The
SBR-25LI
is a high-performance Li-Ion battery providing long operating
time in a compact package. Under normal use, the
SBR-25LI
may be used
for approximately 300 charge cycles, after which operating time may be ex-
pected to decrease. When an old battery pack exhibits diminished capacity,
replace the pack with a new one.
Installing the Battery Pack
1. Insert the battery pack into the bat-
tery compartment on the back of the
transceiver(
).
2. Push the battery in until the battery
latch on the lower back side of the
transceiver clicks securely(
).
