force.
Notes:
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 connector 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.
Installation of FNB-83 Battery Pack
The FNB-83 is a high-performance Ni-MH battery providing high capacity in a compact
package. Under normal use, the FNB-83 may be used for approximately 300 charge cycles,
after which operating time may be expected to decrease. If you have an old battery pack
which is displaying capacity which has become diminished, you should replace the pack with
a new one.
Installation of the battery is easy and quick:
Insert the battery pack into the battery compartment on the back of the radio while tilting
the Belt Clip outward, then close the Battery Pack Latch until it locks in place with a
"Click."
To remove the battery, turn the radio off and remove any protective cases. Open the
Battery Pack Latch on the bottom of the radio, then slide the battery downward and out
from the radio while tilting the Belt Clip out of the way.
Battery Charging
If the battery has never been used, or its charge is depleted, it may be charged by connecting
the NC-88 Overnight Battery Charger, as shown in the illustration, to the EXT DC jack. If only
12 ~ 16 Volt DC power is available, the optional E-DC-5B DC Adapter (with its cigarette
lighter plug) may also be used for charging the battery.
A fully-discharged pack will be charged completely in 10 hours. Disconnect the NC-88 from
the EXT DC jack and the AC line outlet.
Important Note
The NC-88 is not designed to power the transceiver for operation (reception or
transmission).
Do not leave the NC-88 connected to the transceiver for continuous periods in excess of
24 hours. Long term overcharging can degrade the Ni-MH battery pack and significantly
shorten its useful life.
